add-glamo-mci-slower-clocking-dynamic-switching.patch
This patch gives glamo-mci a concept of a platform-defined
dynamic clock slowing callback. It means that platform code
can associate some completely external state to decide if
we run the SD clock at normal rate or a rate divided by a
module parameter "sd_slow_ratio", which you can set on
kernel commandline like this:
glamo_mci.sd_slow_ratio=8
you can also change it at runtime by
echo 8 > /sys/module/glamo_mci/parameters/sd_slow_ratio
If no platform callback is defined, then no slow mode
is used. If it is defined, then the default division
action is / 8, eg, 16MHz normal -> 2MHz slow mode.

fix-allow-full-sd-voltage-range-selection.patch
Until now we just drove the SD Card at 3.3V all the time. But in
fact we can do better, and use a voltage negotiated with the
SD Card itself.
With the shipping 512MB Sandisk SD Card, 2.7V is negotiated which
gives 1.7dBm reduction in power on all the SD Card lines and should
further reduce GPS perturbation during SD Card usage.

fix-glamo-mci-ensure-more-than-74-clocks-after-power.patch
We are meant to run SD_CLK a little while after power-on for the SD
Card, but with the no idle clock changes we didn't take care about it.
This makes us sleep a little bit before disabling clock if we just
powered up the SD Card.

fix-glamo-mci-possible-timeout-overflow.patch
The MMC stack hands us a timeout calibrated in SD_CLK clocks, but the
Glamo can only deal with up to 65520 clocks of timeout. If the stack
handed us a request bigger than this, it would just wrap and the
timeout we actually used would be way too short.
With this patch if that happens, we use the longest timeout we can,
65520 clocks and give it our best shot.

fix-glamo-mci-set-default-drive-level-0.patch
Tests on access to SD Card with Glamo drive level "0" show
that it reduces SD_CLK energy at 1.5GHz by 24dBm compared to
drive level 3. This puts it only 6dB above the background
noise floor compared to 30dB and should make a solution for
GPS trouble with SD Card in.
SD card communication seems unaffected so far on the Sandisk
512MB card we ship.

fix-bq27000-charger-state-tracking.patch
Charger trigger stuff goes and asks for POWER_SUPPLY_PROP_STATUS
to figure out what the charger state is. But until now, we only
reported there what we found out from HDQ, and the HDQ registers
are not updated very often in the coulomb counter, it can be 4
or more second lag before it tells us about what it experiences.
When we react to USB insertion and only after 500ms debounce tell
power_supply stuff that something changed, it most times will
see old pre-USB-insertion state from bq27000 over HDQ at that time
and will report it ain't charging, buggering up the LED trigger
tracking.
This patch maintains distance between bq27000 and pcf50633 by
having platform callbacks in bq27000 that it can use to ask about
definitive charger "online" presence and "activity", whether the
charger says it is charging. If these callbacks are implemented
(and we implement them in this patch up in mach_gta02.c) then
this information is used in preference to what is found from
HDQ.
Result is if you set the LED trigger like this:
echo bat-charging > /sys/devices/platform/gta02-led.0/leds/gta02-aux:red/trigger
then it lights up properly on USB insertion now, goes away on
removal properly, as as far as I saw, when charging stops too.

debug-add-glamo-drive-strength-module-param.patch
Suggested-by: Werner Almesberger <werner at openmoko.org>
This patch allows users to control two additional settings
in Glamo MCI driver from kernel commandline or module
parameters.
First is Glamo drive strength on SD IOs including CLK.
This ranges from 0 (weakest) to 3 (strongest).
echo 0 > /sys/module/glamo_mci/parameters/sd_drive
(Changes to this take effect on next SD Card transaction)
or, from kernel commandline
glamo_mci.sd_drive=0
On tests here with 0 strength, communication to SD card
(shipped 512MB Sandisk) seemed fine, and a dd of 10MB
urandom had the same md5 when written to cache as after
a reboot. I set the default to 2.
Second is whether we allow SD_CLK when the SD interface
is idle.
# stop the clock when we are idle (default)
echo 0 > /sys/module/glamo_mci/parameters/sd_idleclk
# run the SD clock all the time
echo 1 > /sys/module/glamo_mci/parameters/sd_idleclk
(changes take effect on next SD Card transaction)
From kernel commandline, eg:
glamo_mci.sd_idleclk=1
Normally you don't want to run the SD Clock all the time.

else. It would mean we have a pretty fine race in there

fix-scard-stop-on-resume.patch
Reported-by: Ville-Pekka Vainio <vpivaini at cs.helsinki.fi>
The reporter noticed SD Card clock is running again after resume. After
looking at the code I saw I missed two tricks, this will force it off
after resume and will do better generally depending on what the last SD Card
packet was.
Since bulk read packet is normally last action (which set the clock off even
without this) the old patch worked for normal cases. But after resume, the last
packet on the wire was not a bulk transfer and we didn't take care about the
clock then.

add-limit-sdcard-clk-cmdline.patch
This patch allows you to control the maximum clock rate that will
be selected for SD Card access, from the kernel commandline using
glamo_mci.sd_max_clk=10000000
and also from
echo 10000000 > /sys/module/glamo_mci/parameters/sd_max_clk
although you have to suspend and resume to make the limit operational
on the actual SD_CLK line.
Clocks that are possible are divided down from ~50MHz, so 25000000,
16666666, 12500000, 10000000, etc. With Freerunner A5 revision that
has 100R series resistors in SD Card signals, I didn't get reliable
operation above 16MHz. With A6 revision the series resistors went
down to 75R, maybe it can work at 25MHz.
Reducing the clock rate is something to try if you find that your
SD Card is not communicating properly with the default speed.

fix-force-sdcard-clk-off-when-idle.patch
Existing Glamo bit for stopping SD Card Clock when there is no
transfer taking place does not work. This patch adds stuff around
the transfer code to force the SD clock up when something is going on
and down when it is idle. This'll save a little power and noise ;-)
I tested it briefly and was able to SD Boot normally on Sandisk 512M.
Wider testing is appreciated.

sdio: use interruptible sleep in kthread main loops
My FreeRunner's load average was leveling off at 2.00 as a result of
these two kernel threads:

This fixes them to use interruptible sleep primitives while waiting in
their main loops, as is conventional for kernel threads. They can't
actually be interrupted since kernel threads ignore all signals, but
by sleeping this way they get classified as long term waiters, and
don't get counted as running for purposes of load average calculation.
This is intended as a minimal fix. In the longer term, it'd probably
make sense to replace the semaphores with completions or something,
and to do away with some of these StudlyCapped wrapper functions.

introduce-BANKCON-meddling-sysfs.patch
A few questions have been flying around about how optimal
our waitstates are for various things including Glamo.
This patch introduces new sysfs nodes
/sys/devices/platform/neo1973-memconfig.0/BANKCON0
...
/sys/devices/platform/neo1973-memconfig.0/BANKCON7
If you cat them you get translated info about bus speed on
that chip select, eg,
# cat /sys/devices/platform/neo1973-memconfig.0/BANKCON1
BANKCON1 = 0x00000A40
Type = ROM / SRAM
PMC = normal (1 data)
Tacp = 2 clocks
Tcah = 0 clocks
Tcoh = 1 clock
Tacc = 3 clocks
Tcos = 1 clock
Tacs = 0 clocks
You can write them in hex too
# echo 0x200 > /sys/devices/platform/neo1973-memconfig.0/BANKCON1
The write format for BANKCON0 - 5 looks like this
b1..b0 PMC Page Mode Config
b3..b2 Tacp Page Mode Access Cycle
b5..b4 Tcah Address hold after CS deasserted
b7..b6 Tcoh CS hold after OE deasserted
b10..b8 Tacc Access Cycle Period
b12..b11 Tcos CS setup before OE asserted
b14..b13 Tacs Address setup before CS asserted
BANKCON 6 and 7 have two extra bits
b16..b15 MT Memory type (00=ROM/SRAM, 11=DRAM)
If it's ROM/SRAM, the rest of the bits are as described above.
For DRAM
b1..b0 SCAN Column address number
b3..b2 RAS to CAS delay
The patch is intended to let people experiement on their own. But
of course you will crash things for sure if the timing is wrong, and
you can also trash SD Card data if you make Glamo unstable, so remove
it or remount ro first. Other horrible things are possible, but
because the settings aren't sticky, you should always be able to
recover by either normal reboot usually or at worst NOR boot and then
dfu. Most likely you will just crash your session and have to reboot
if your settings are bad, but consider yourself warned bad things are
possible. :-)

changes us to set backlight back to last requested backlight
brightness level on resume. Note it means that you can
resume with screen blanked, but it should come back if that
happened with touchscreen action as usual.

fix-no-uart-leak-when-gps-off.patch
During the suspend current reduction campaign on suspend I
forced the GPS UART to be GPIO and to drive 0 into the GPS
unit so we would not burn current there. On resume it lets
the pins act as UARTs again. But really, we should do this
all the time that the GPS unit is off, lest we leak it
enough power to hold internal state and make trouble.

add-pcf50633-allow-force-charger-type.patch
This patch adds a sysfs node:
/sys/class/i2c-adapter/i2c-0/0-0073/force_usb_limit_dangerous
it allows to force the charging limit regardless of the one chosen
by pcf50633 kernel driver. As such, if you write a charging limit
here that is not suitable for the power source, and the power source
is not current limited on its side, it could draw more current than
your power source can handle, burn down you house, etc.
If you're certain that your power supply can handle it, you can use
this on your own responsibility to make the amount drawn by the
PMU match what you believed your power supply could handle.
Example usage, in case where you have a dumb 500mA USB charger that
does not have the ID resistor:
# cat /sys/class/i2c-adapter/i2c-0/0-0073/charger_type
host/500mA usb mode 100mA <=== dumb charger does not ennumerate us
# echo 500 > /sys/class/i2c-adapter/i2c-0/0-0073/force_usb_limit_dangerous
# cat /sys/class/i2c-adapter/i2c-0/0-0073/charger_type

introduce-resume-exception-capture.patch
This patch introduces a new resume debugging concept: if we
get an OOPS inbetween starting suspend and finishing resume, it
uses a new "emergency spew" device similar to BUT NOT REQUIRING
CONFIG_DEBUG_LL to dump the syslog buffer and then the OOPS
on the debug device defined by the existing CONFIG_DEBUG_S3C_UART
index. But neither CONFIG_DEBUG_LL nor the S3C low level configs
are needed to use this feature.
Another difference between this feature and CONFIG_DEBUG_LL is that
it does not affect resume timing, ordering or UART traffic UNLESS
there is an OOPS during resume.
The patch adds three global exports, one to say if we are inside
suspend / resume, and two callbacks for printk() to use to init
and dump the emergency data. The callbacks are set in s3c serial
device init, but the whole structure is arch independent.

This patch
- adds a diagnostic dump feature down /sys
- forces BOOT action on init and resume, and waits for
completion
- makes sure XYZ capture is enabled on resume
- adds some constants in the .h and removes some magic numbers

touchscreen-meddling.patch
Touchscreen on GTA01-02 experiences noise on the channel that serves the
"tall axis" of the LCM. The sample quality of the other axis is good.
The bad samples have a characteristic of one shot excursions that can
reach +/- 20% or more of the sample average.
Previously, we had a simple averaging scheme going in the touchscreen
driver that summed up 32 x and ys and then divided it by 32. This patch
first tidies up the existing code for style, then adds a new "running
average" concept with a FIFO. The running average is separate from the
summing average mentioned above, and is accurate for the last n samples
sample-by-sample, where n is set by 1 << excursion_filter_len_bits in the
machine / platform stuff.
The heuristic the patch implements for the filtering is to accept all
samples, but tag the *previous* sample with a flag if it differed from
the running average by more than reject_threshold_vs_avg in either
axis. The next sample time, a beauty contest is held if the flag was
set to decide if we think the previous sample was a one-shot excursion
(detected by the new sample being closer to the average than to the
flagged previous sample), or if we believe we are moving (detected by
the new sample being closer to the flagged previous sample than the
average. In the case that we believe the previous sample was an
excursion, we simply overwrite it with the new data and adjust the
summing average to use the new data instead of the excursion data.
I only tested this by eyeballing the output of ts_print_raw, but it
seemed to be quite a bit better. Gross movement appeared to be
tracked fine too. If folks want to try different heuristics on top
of this patch, be my guest; either way feedback on what it looks like
with a graphical app would be good.

Basically-solved-by: Graeme Gregory <graeme at openmoko.org>
Graeme found a while back that on resume, IISCON register in
s3c2442 does not show LRCK toggling in LRINDEX bit any more,
causing s3c24xx_snd_lrsync() to timeout and return an error,
aborting restart of any live stream that was playing at
suspend.
I confirmed it was true, meddled around for a bit looking
for some magic to restart LRCK or at least the reporting of
it, and in the end worked around it using the method noted
by Graeme: just ignore LRCK sync if it timed out. The worst
that could happen would be L and R swap for the duration of
stream that was suspended into but probably not even that.

Two issues... we never took care to take down engines in suspend
and bring them back in resume. This was part of the display
corruption that could be seen briefly on resume. The other issue
that made the "noise" corruption was bad ordering of resume steps.
This patch simplifies (removing needless re-init) resume actions
and makes explicit the suspend and resume steps. It also adds
code to track which engines are up and push them down in suspend
and bring them back in resume.
The result is no more corruption of display buffer in suspend, it
comes back completely clean.

fix-pcf50633-really-defer-backlight-on-resume.patch
Backlight wasn't off by default on resume, so it was never really
deferred (until LCM is initialized). This fixes that and so removes
the brief white screen between pcf50633 resume and LCM init.

fix-pcf50633-disable-irq-from-suspend-until-resume.patch
Disable pcf interrupt (not for wake, just as interrupt) in
suspend, re-enable it again just before we force-call the
workqueue function at end of pcf resume, which leads to
pcf interrupt source registers getting cleared so it can
signal an interrupt normally again.
This change ends the uncontrolled appearance of pcf interrupts
during resume time which previously caused the work to attempt
to use the I2C stuff before i2c host device had itself resumed.
Now the isr work is only queued, and the isr work function called,
definitively after pcf resume completes.
In suspend time, the work function may have been queued some
time before and be pending, and it could still show up at a
bad time. Therefore if the work function sees that it is
coming since the start of pcf50633 suspend function, it
aborts without attempting to read the pcf interrupt regs,
leaving them for resume to take care of.
USB current limit and no battery work functions are also made
aware of suspend state and act accordingly.
Lastly I noticed that in early resume, i2c_get_clientdata(&pcf->client)
returns NULL, presumably because i2c device is still suspended. This
could easily make trouble for async events like interrupt work,
since pcf pointer is the client data. Disabling appearance of the
work until after pcf50633 resume will also avoid that.

fix-pcf50633-kill-white-splash-of-death-on-suspend.patch
mach-gta02 meddles with the regulator platform struct after
it is defined, leading to LCM power getting lost in suspend
despite I set it to be left up. Fixing this finally removes
the incredibly stubborn white LCM on suspend "flash".
This is also going to be implicated in Sean McNeil's
experience of monochromatic LCM after resume, which was
previously attacked by resetting and re-initing the LCM
from scratch.
In addition, I realized that we take down core_1v3 in
pcf50633 suspend action, this is happening near the
start of suspend, so we are in a meta-race to finish
suspend in a controlled way before the caps on core_1v3
run out (I only saw 23.3uF total). If it's true, this
is where the weirdo sensitivity to timing during
suspend is coming from.
Therefore in this patch we also remove sleeps and
dev_info() etc (which have to flush on serial console)
from the pc50633 isr workqueue if we are in pcf50633
driver suspend state 1, ie, suspending... because we
don't have time for it.

introduce-charging-led-behaviour.patch
Creates a new behaviour requested by Will that the red LED on GTA02
is lit during battery charging.and goes out when the battery is full.
This is done by leveraging the PMU interrupts, but in one scenario
there is no interrupt that occurs, when the battery is replaced after
being removed with the USB power in all the while. So a sleepy work
function is started under those circumstances to watch for battery
reinsertion or USB cable pull.
100mA limit was not being observed under some conditions so this was
fixed and tested with a USB cable with D+/D- disconnected. 1A
charger behaviour was also tested.
Showing the charging action exposes some inconsistency in pcf50633
charging action. If your battery is nearly full, it will keep
charging it at decreasing current even after it thinks it is at
100% capacity for a long while. But if you pull that same battery
and re-insert it, the charger state machine in pcf50633 believe it is
full and won't charge it.

serial traffic appears to be synchronous)
Added a platform callback in jbt driver and support in pcf50633 so we
can defer bringing up the backlight until the LCM is able to process
video again (which must happen after the glamo is up and producing
video beacuse the LCM is hooked to glamo SPI)
GTA01 should not be affected by all this as the callback will default
to null and it is on pcf50606

Enable GPS only if it was powered on before suspending the device
Similar to the neo1974_pm_gsm.c keep a static struct around. On suspend
we will save the current power state, on resume we will use this
information to enable power of the GPS only when it was powered on before.
This is passing basic tests with screen /dev/ttySAC1 on suspend and resume.
Only do this for the GTA02 as I don't have a gllin setup for the GTA01
I wonder why the suspend and resume code is not using gps_pwron_set and why
for the GTA02 we need to keep the state of the GPIOs, this should be done
by the s3c code.

Fix the firing of "Jack"-Interrupts after resume when the modem is powered on.
GTA02_GPIO_nDL_GSM defaults to high/1. On resume do not enable the DL_GSM if
it was not enabled before. This is stopping the storm of interrupts.
Fix the logic in the download file handling. Downloads are disabled (0) when
the GTA02_GPIO_nDL_GSM is high (1). To enable downloading set
GTA02_GPIO_nDL_GSM to low (0, !on). Disable the jack interrupt while download
the is active. When disabling download we will get a couple of jack interrupts
but this is hardly avoidable.
Avoid reading the GPIO value if we do not even have a console set.

introduce-usb-host-power-control.patch
Unless I really really missed the point, there is no support for enabling
USB Host power for USB host mode. This patch adds a /sys node for GTA02
that allows control of the charge pump for 5V out on the USB mini connector
It doesn't change any logical mode in the CPU, just enables (1) and disables
(0) USB host power.

fix-glamo-mci-defeat-ops-during-suspend.patch
We need to be able to use the config option CONFIG_MMC_UNSAFE_RESUME that allows the rootfs
to live on SD. But when we use this, it tries to send a reset command to the SD card during
suspend -- and unfortunately many things like Power have suspended by then.
This patch again rejects IO on the MMC device during suspend of the MMC device, and it
gives the result the rootfs on SD card works okay.

introduce-bq27000-battery-driver.patch
This is a driver for the bq27000 found in the Highcell A5
battery, and the platform device stuff for it for GTA02. It
is a Power Supply Class battery device.
The driver doesn't contain an HDQ engine but accepts pointers
from the platform data to the HDQ action routines; our
platform data plugs it into the FIQ HDQ engine stuff.
The Power Supply class exposes the battery down /sys so you
can find out battery status by doing the equivalent of this
bash command
for i in capacity charge_full current_now present status technology temp time_to_empty_now time_to_full_now type voltage_now ; do echo -n "$i " ; cat /sys/devices/platform/bq27000-battery.0/power_supply/bat/$i ; done
Here is the kind of result you get from a battery discharging
capacity 0
charge_full 1215585
current_now 183375
present 1
status Discharging
technology Li-ion
temp 276
time_to_empty_now 0
time_to_full_now 3932100
type Battery
voltage_now 2761000
Note that temp is in 1/10 degrees C, other values are in uV,
uA, uW. The time_to_* reported are bogus, but that is what
the battery actually reports.
We can make more mappings to entries in power_supply class
but this is enough to get started with.

introduce-fiq-hdq.patch
This adds a platform driver and device which performs HDQ
battery protocol using a single GPIO pin which is set
through platform data.
HDQ has some hard latency requirements which can't
be met if interrupts are enabled, so normally using
a GPIO for this will require blocking out all other
interrupts and processes for several milliseconds
per register being read or written.
This HDQ protocol engine is a FSM implemented inside the
the FIQ ISR and regulated by timer interrupts happening
at 20us intervals. The path through the FSM on any
"clock" is very short and should be over with in ~
1us. Because FIQ has guaranteed latencies of <1us,
it means we can service the HDQ protocol without
blocking interrupts or any other process other than
the caller that is waiting for the result. It's pretty
cool performance from 1 GPIO ;-)
Due to it being hard to do locking from the FIQ ISR
the code simply sleeps 10ms or whatever the scheduler
gives it and checks if the transfer took place yet.
This platform driver doesn't have any knowledge about
the device it is talking to, it just knows it is a
HDQ device. It exports three functions for read, write
and confirming HDQ is initialized. It also exports two
/sys nodes that are usable by humans, one dumps the whole
127 register HDQ register space

s3c2410_udc-2440_dual_packet-workaround.patch
This is a patch that seems to make the USB hangs on the S3C2440 go away. At
least a good amount of ping torture didn't make them come back so far.
The issue is that, if there are several back-to-back packets,
sometimes no interrupt is generated for one of them. This
seems to be caused by the mysterious dual packet mode, which
the USB hardware enters automatically if the endpoint size is
half that of the FIFO. (On the 2440, this is the normal
situation for bulk data endpoints.)
There is also a timing factor in this. I think what happens is
that the USB hardware automatically sends an acknowledgement
if there is only one packet in the FIFO (the FIFO has space
for two). If another packet arrives before the host has
retrieved and acknowledged the previous one, no interrupt is
generated for that second one.
However, there may be an indication. There is one undocumented
bit (none of the 244x manuals document it), OUT_CRS1_REG[1],
that seems to be set suspiciously often when this condition
occurs. There is also CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which
may have a function related to this. (The Samsung manual is
rather terse on that, as usual.)
This needs to be examined further. For now, the patch seems to do the
trick.
Note that this is not a clean solution by any means, because we
might potentially get stuck in that interrupt for quite a while.

This is a MMC/SD driver for the Samsung S3C24xx SD/MMC controller, originally

Due to time restraints, he had no time to further maintain the driver and
follow the mainline Linux changes in the SD/MMC stack.
With his authorization, I have taken over the task of making it compliant to
the current mainline SD/MMC API and take care of the mainline kernel merge.
After a potential kernel inclusion, we would co-maintain the driver.

try harder to load tty ldisc driver
Currently function tty_ldisc_get() tries to load an ldisc driver module
only when tty_ldisc_try_get() returns -EAGAIN. This happens only if
module is being unloaded. If ldisc module is not loaded
tty_ldisc_try_get() returns -EINVAL and this case is not handled in
tty_ldisc_get(), so request_module() is not called.
Attached patch fixes this by calling request_module() if
tty_ldisc_try_get() returned any error code.
I discovered this when my UMTS modem stopped working with 2.6.27-rc1
because module ppp_async was not loaded.

mm/hugetlb: don't crash when HPAGE_SHIFT is 0
Some platform decide whether they support huge pages at boot time. On
these, such as powerpc, HPAGE_SHIFT is a variable, not a constant, and is
set to 0 when there is no such support.
The patches to introduce multiple huge pages support broke that causing
the kernel to crash at boot time on machines such as POWER3 which lack
support for multiple page sizes.

Missing symbol prefix on vmlinux.lds.h
ARCH=h8300:
init/main.c:781: undefined reference to `___early_initcall_end'
Same problem have
__start___bug_table
__stop___bug_table
__tracedata_start
__tracedata_end
__per_cpu_start
__per_cpu_end
When defining a symbol in vmlinux.lds, use the VMLINUX_SYMBOL macro.
VMLINUX_SYMBOL adds a prefix charactor.
You can't just use straight symbol names in common header files as they
dont take into consideration weird arch-specific ABI conventions. in the
case of Blackfin/h8300, the ABI dictates that any C-visible symbols have
an underscore prefixed to them. Thus all symbols in vmlinux.lds.h need to
be wrapped in VMLINUX_SYMBOL() so that each arch can put hide this magic
in their own files.

PNP: fix formatting of dbg_pnp_show_resources() output
Each resource should be printed on its own line, so start snprintf'ing
at the beginning of the buffer every time through the loop.
Also, use scnprintf() rather than snprintf() when building up the
buffer to print. scnprintf() returns the number of characters actually
written into the buffer (not including the trailing NULL).
snprintf() returns the number of characters that *would be* written,
assuming everything would fit in the buffer. That's nice if we want to
resize the buffer to make sure everything fits, but in this case, I
just want to keep from overflowing the buffer, and it's OK if the
output is truncated.
Using snprintf() meant that my "len" could grow to be more than the
the buffer size, which makes "sizeof(buf) - len" negative, which causes
this alarming WARN_ON:

Remove newline from the description of module parameters
Some module parameters with only one line have the '\n' at the end of the
description. This is not needed nor wanted as after the description the
type (i.e. int) is followed by a newline.
Some modules contain a multi-line description, these are not affected
by this patch.

tracehook: fix exit_signal=0 case
My commit 2b2a1ff64afbadac842bbc58c5166962cf4f7664 introduced a regression
(sorry about that) for the odd case of exit_signal=0 (e.g. clone_flags=0).
This is not a normal use, but it's used by a case in the glibc test suite.
Dying with exit_signal=0 sends no signal, but it's supposed to wake up a
parent's blocked wait*() calls (unlike the delayed_group_leader case).
This fixes tracehook_notify_death() and its caller to distinguish a
"signal 0" wakeup from the delayed_group_leader case (with no wakeup).

Raise the DMA block size limit from 2048 bytes to the maximum supported

kernel/audit.c control character detection is off-by-one
Hello,
According to my understanding there is an off-by-one bug in the
function:
audit_string_contains_control()
in:
kernel/audit.c
Patch is included.
I do not know from how many places the function is called from, but for
example, SELinux Access Vector Cache tries to log untrusted filenames via
call path:
avc_audit()
audit_log_untrustedstring()
audit_log_n_untrustedstring()
audit_string_contains_control()
If audit_string_contains_control() detects control characters, then the
string is hex-encoded. But the hex=0x7f dec=127, DEL-character, is not
detected.
I guess this could have at least some minor security implications, since a
user can create a filename with 0x7f in it, causing logged filename to
possibly look different when someone reads it on the terminal.

[PATCH] Audit: Collect signal info when SIGUSR2 is sent to auditd
Makes the kernel audit subsystem collect information about the sending
process when that process sends SIGUSR2 to the userspace audit daemon.
SIGUSR2 is a new interesting signal to auditd telling auditd that it
should try to start logging to disk again and the error condition which
caused it to stop logging to disk (usually out of space) has been
rectified.

[PATCH 1/2] proc: fix inode number bogorithmetic
Id which proc gets from IDR for inode number and id which proc removes
from IDR do not match. E.g. 0x11a transforms into 0x8000011a.
Which stayed unnoticed for a long time because, surprise, idr_remove()
masks out that high bit before doing anything.
All of this due to "| ~MAX_ID_MASK" in release_inode_number().
I still don't understand how it's supposed to work, because "| ~MASK"
is not an inversion for "& MAX" operation.
So, use just one nice, working addition. Make start offset unsigned int,
while I'm at it. It's longness is not used anywhere.

[S390] Optimize storage key operations for anon pages
For anonymous pages without a swap cache backing the check in
page_remove_rmap for the physical dirty bit in page_remove_rmap is
unnecessary. The instructions that are used to check and reset the dirty
bit are expensive. Removing the check noticably speeds up process exit.
In addition the clearing of the dirty bit in __SetPageUptodate is
pointless as well. With these two changes there is no storage key
operation for an anonymous page anymore if it does not hit the swap
space.
The micro benchmark which repeatedly executes an empty shell script
gets about 5% faster.

kgdb: fix gdb serial thread queries
The command "info threads" did not work correctly with kgdb. It would
result in a silent kernel hang if used.
This patach addresses several problems.
- Fix use of deprecated NR_CPUS
- Fix kgdb to not walk linearly through the pid space
- Correctly implement shadow pids
- Change the threads per query to a #define
- Fix kgdb_hex2long to work with negated values
The threads 0 and -1 are reserved to represent the current task. That
means that CPU 0 will start with a shadow thread id of -2, and CPU 1
will have a shadow thread id of -3, etc...
From the debugger you can switch to a shadow thread to see what one of
the other cpus was doing, however it is not possible to execute run
control operations on any other cpu execept the cpu executing the
kgdb_handle_exception().

kgdb: fix kgdb_validate_break_address to perform a mem write
A regression to the kgdb core was found in the case of using the
CONFIG_DEBUG_RODATA kernel option. When this option is on, a breakpoint
cannot be written into any readonly memory page. When an external
debugger requests a breakpoint to get set, the
kgdb_validate_break_address() was only checking to see if the address
to place the breakpoint was readable and lacked a write check.
This patch changes the validate routine to try reading (via the
breakpoint set request) and also to try immediately writing the break
point. If either fails, an error is correctly returned and the
debugger behaves correctly. Then an end user can make the
descision to use hardware breakpoints.
Also update the documentation to reflect that using
CONFIG_DEBUG_RODATA will inhibit the use of software breakpoints.

Fix rename of at91_nand -> atmel_nand
Structs called at91_nand_data where renamed to atmel_nand_data
and configs called *MTD_NAND_AT91* where renamed to
*MTD_NAND_ATMEL*. This was unfortunately not done consistently,
causing NAND chips not being initialised on several ARM boards.
I am aware that the author of the original change did not rename
MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example.
All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order
to keep naming consistency.
This patch was only tested on a MACH_SAM9_L9260, as this is the
only ARM board I have to my disposal.

ipv6: Fix ip6_xmit to send fragments if ipfragok is true
SCTP used ip6_xmit() to send fragments after received ICMP packet too
big message. But while send packet used ip6_xmit, the skb->local_df is
not initialized. So when skb if enter ip6_fragment(), the following
code will discard the skb.
ip6_fragment(...)
{
if (!skb->local_df) {
...
return -EMSGSIZE;
}
...
}
SCTP do the following step:
1. send packet ip6_xmit(skb, ipfragok=0)
2. received ICMP packet too big message
3. if PMTUD_ENABLE: ip6_xmit(skb, ipfragok=1)
This patch fixed the problem by set local_df if ipfragok is true.

ipvs: Move userspace definitions to include/linux/ip_vs.h
Current versions of ipvsadm include "/usr/src/linux/include/net/ip_vs.h"
directly. This file also contains kernel-only definitions. Normally, public
definitions should live in include/linux, so this patch moves the
definitions shared with userspace to a new file, "include/linux/ip_vs.h".
This also removes the unused NFC_IPVS_PROPERTY bitmask, which was once
used to point into skb->nfcache.
To make old ipvsadms still compile with this, the old header file includes
the new one.
Thanks to Dave Miller and Horms for noting/adding the missing Kbuild entry
for the new header file.

hwmon: (lm85) Simplify device initialization function
Clean up and simplify the device initialization function:
* Degrade error messages to warnings - what they really are.
* Stop warning about VxI mode, we don't really care.
* Drop comment about lack of limit initialization - that's the standard
way, all hardware monitoring drivers do that.
* Only read the configuration register once.
* Only write back to the configuration register if needed.
* Don't attempt to clear the lock bit, it locks itself to 1.
* Move the function to before it's called, so that we no longer need to
forware declare it.

hwmon: (lm75) add new-style driver binding
More LM75 updates:
- Teach the LM75 driver to use new-style driver binding:
* Create a second driver struct, using new-style driver binding
methods cribbed from the legacy code.
* Add a MODULE_DEVICE_TABLE (for "newER-style binding")
* The legacy probe logic delegates its work to this new code.
* The legacy driver now uses the name "lm75_legacy".
- More careful initialization. Chips are put into 9-bit mode so
the current interconversion routines will never fail.
- Save the original chip configuration, and restore it on exit.
(Among other things, this normally turns off the mode where
the chip is constantly sampling ... and thus saves power.)
So the new-style code should catch all chips that boards declare,
while the legacy code catches others. This particular coexistence
strategy may need some work yet ... legacy modes might best be set
up explicitly by some tool not unlike "sensors-detect". (Or else
completely eradicated...)

- Section comments now delineate the various sections of the driver:
hwmon attributes, driver binding, register access, module glue.
One driver binding function moved out of the attribute section,
as did the driver struct itself.
- Minor tweaks to legacy probe logic: correct a comment, and

- Whitespace, linelength, and comment fixes.

[PATCH 2/2] ocfs2: Fix race between mount and recovery
As the fs recovery is asynchronous, there is a small chance that another
node can mount (and thus recover) the slot before the recovery thread
gets to it.
If this happens, the recovery thread will block indefinitely on the
journal/slot lock as that lock will be held for the duration of the mount
(by design) by the node assigned to that slot.
The solution implemented is to keep track of the journal replays using
a recovery generation in the journal inode, which will be incremented by the
thread replaying that journal. The recovery thread, before attempting the
blocking lock on the journal/slot lock, will compare the generation on disk
with what it has cached and skip recovery if it does not match.
This bug appears to have been inadvertently introduced during the mount/umount
vote removal by mainline commit 34d024f84345807bf44163fac84e921513dde323. In the
mount voting scheme, the messaging would indirectly indicate that the slot
was being recovered.

[PATCH] configfs: Pin configfs subsystems separately from new config_items.
configfs_mkdir() creates a new item by calling its parent's
->make_item/group() functions. Once that object is created,
configfs_mkdir() calls try_module_get() on the new item's module. If it
succeeds, the module owning the new item cannot be unloaded, and
configfs is safe to reference the item.
If the item and the subsystem it belongs to are part of the same module,
the subsystem is also pinned. This is the common case.
However, if the subsystem is made up of multiple modules, this may not
pin the subsystem. Thus, it would be possible to unload the toplevel
subsystem module while there is still a child item. Thus, we now
try_module_get() the subsystem's module. This only really affects
children of the toplevel subsystem group. Deeper children already have
their parents pinned.

This commit adds the necessary inode locking to safely remove configfs

Two bugs:
1/ "A/B/C" and "A/C/E" are created, but never removed while their parent are
removed in the end. The same could happen with symlink() instead of mkdir().
2/ "A" and "A/C" inodes are not locked while detach_item() is called on them,
which may probably confuse VFS.
This commit fixes 1/, tagging new directories with CONFIGFS_USET_CREATING before
building the inode and instantiating the dentry, and validating the whole
group+default groups hierarchy in a second pass by clearing
CONFIGFS_USET_CREATING.
mkdir(), symlink(), lookup(), and dir_open() simply return -ENOENT if
called in (or linking to) a directory tagged with CONFIGFS_USET_CREATING. This
does not prevent userspace from calling stat() successfuly on such directories,
but this prevents userspace from adding (children to | symlinking from/to |
read/write attributes of | listing the contents of) not validated items. In
other words, userspace will not interact with the subsystem on a new item until
the new item creation completes correctly.
It was first proposed to re-use CONFIGFS_USET_IN_MKDIR instead of a new
flag CONFIGFS_USET_CREATING, but this generated conflicts when checking the
target of a new symlink: a valid target directory in the middle of attaching
a new user-created child item could be wrongly detected as being attached.
2/ is fixed by next commit.

[PATCH] configfs: Fix failing symlink() making rmdir() fail
On a similar pattern as mkdir() vs rmdir(), a failing symlink() may make rmdir()
fail for the symlink's parent and the symlink's target as well.
failing symlink() making target's rmdir() fail:
process 1: process 2:
symlink("A/S" -> "B")
allow_link()
create_link()
attach to "B" links list
rmdir("B")
detach_prep("B")
error because of new link
configfs_create_link("A", "S")
error (eg -ENOMEM)
failing symlink() making parent's rmdir() fail:
process 1: process 2:
symlink("A/D/S" -> "B")
allow_link()
create_link()
attach to "B" links list
configfs_create_link("A/D", "S")
make_dirent("A/D", "S")
rmdir("A")
detach_prep("A")
detach_prep("A/D")
error because of "S"
create("S")
error (eg -ENOMEM)
We cannot use the same solution as for mkdir() vs rmdir(), since rmdir() on the
target cannot wait on the i_mutex of the new symlink's parent without risking a
deadlock (with other symlink() or sys_rename()). Instead we define a global
mutex protecting all configfs symlinks attachment, so that rmdir() can avoid the
races above.

[PATCH] configfs: Fix symlink() to a removing item
The rule for configfs symlinks is that symlinks always point to valid
config_items, and prevent the target from being removed. However,
configfs_symlink() only checks that it can grab a reference on the target item,
without ensuring that it remains alive until the symlink is correctly attached.
This patch makes configfs_symlink() fail whenever the target is being removed,
using the CONFIGFS_USET_DROPPING flag set by configfs_detach_prep() and
protected by configfs_dirent_lock.
This patch introduces a similar (weird?) behavior as with mkdir failures making
rmdir fail: if symlink() races with rmdir() of the parent directory (or its
youngest user-created ancestor if parent is a default group) or rmdir() of the
target directory, and then fails in configfs_create(), this can make the racing
rmdir() fail despite the concerned directory having no user-created entry (resp.
no symlink pointing to it or one of its default groups) in the end.
This behavior is fixed in later patches.

kbuild: genksyms parser: fix the __attribute__ rule
We are having two kinds of problems with genksyms today: fake checksum
changes without actual ABI changes, and changes which we would rather like
to ignore (such as an additional field at the end of a structure that
modules are not supposed to touch, for example).
I have thought about ways to improve genksyms and compute checksums
differently to avoid those problems, but in the end I don't see a
fundamentally better way. So here are some genksyms patches for at least
making the checksums more easily manageable, if we cannot fully fix them.
In addition to the bugfixes (the first two patches), this allows genksyms
to track checksum changes and report why a checksum changed (third patch),
and to selectively ignore changes (fourth patch).
This patch:
Gcc __attribute__ definitions may occur repeatedly, e.g.,
static int foo __attribute__((__used__))
__attribute__((aligned (16)));
The genksyms parser does not understand this, and generates a syntax error.
Fix this case.

netfilter: xt_hashlimit: fix race between htable_destroy and htable_gc
Deleting a timer with del_timer doesn't guarantee, that the
timer function is not running at the moment of deletion. Thus
in the xt_hashlimit case we can get into a ticklish situation
when the htable_gc rearms the timer back and we'll actually
delete an entry with a pending timer.
Fix it with using del_timer_sync().
AFAIK del_timer_sync checks for the timer to be pending by
itself, so I remove the check.

netfilter: ipt_recent: fix race between recent_mt_destroy and proc manipulations
The thing is that recent_mt_destroy first flushes the entries
from table with the recent_table_flush and only *after* this
removes the proc file, corresponding to that table.
Thus, if we manage to write to this file the '+XXX' command we
will leak some entries. If we manage to write there a 'clean'
command we'll race in two recent_table_flush flows, since the
recent_mt_destroy calls this outside the recent_lock.
The proper solution as I see it is to remove the proc file first
and then go on with flushing the table. This flushing becomes
safe w/o the lock, since the table is already inaccessible from
the outside.

- Switch from WARN to BUG in ata_id_string as it will reboot if you get

- Allow the issue of command 0xFC on the 821x. This is needed to query
rebuild status.
- Tidy up printk formatting
- Do more ident rewriting on RAID volumes to handle firmware provided
ident data which is rather wonky
- Report the firmware revision and device layout in RAID mode
- Don't try and disable raid on the 8211 or RDC - they don't have the

bridge: send correct MTU value in PMTU (revised)
When bridging interfaces with different MTUs, the bridge correctly chooses
the minimum of the MTUs of the physical devices as the bridges MTU. But
when a frame is passed which fits through the incoming, but not through
the outgoing interface, a "Fragmentation Needed" packet is generated.
However, the propagated MTU is hardcoded to 1500, which is wrong in this
situation. The sender will repeat the packet again with the same frame
size, and the same problem will occur again.
Instead of sending 1500, the (correct) MTU value of the bridge is now sent
via PMTU. To achieve this, the corresponding rtable structure is stored
in its net_bridge structure.
Modified to get rid of fake_net_device as well.

Fix off-by-one error in iov_iter_advance()
The iov_iter_advance() function would look at the iov->iov_len entry
even though it might have iterated over the whole array, and iov was
pointing past the end. This would cause DEBUG_PAGEALLOC to trigger a
kernel page fault if the allocation was at the end of a page, and the
next page was unallocated.
The quick fix is to just change the order of the tests: check that there
is any iovec data left before we check the iov entry itself.
Thanks to Alexey Dobriyan for finding this case, and testing the fix.

only an error if the 'romfs_copyfrom()' routine isn't able to fill the
data that is supposed to be there.
Most of the patch is really just re-organizing the code a bit, and using
separate variables for the error value and for how much of the page we
actually filled from the filesystem.

[MIPS] kgdb: add arch support for the kernel's kgdb core
The new kgdb architecture specific handler registers and unregisters
dynamically for exceptions depending on when you configure a kgdb I/O
driver.
Aside from initializing the exceptions earlier in the boot process,
kgdb should have no impact on a device when it is compiled in so long
as an I/O module is not configured for use.
There have been quite a number of contributors during the existence of
this patch (see arch/mips/kernel/kgdb.c). Most recently Jason
re-wrote the mips kgdb logic to use the die notification handlers.

[MIPS] Initialization of Alchemy boards
An earlier update changed some calls from simple_strotl to strict_strtol but
did not account for the differences in the syntax between the calls.
simple_strotl returns the integer; strict_strtol returns an error code and
takes a pointer to the result. As it was, NULL was being passed in place of
the result, which led to failures during kernel initialization when using
YAMON.

GRU Driver: hardware data structures
This series of patches adds a driver for the SGI UV GRU. The driver is
still in development but it currently compiles for both x86_64 & IA64.
All simple regression tests pass on IA64. Although features remain to be
added, I'd like to start the process of getting the driver into the
kernel. Additional kernel drivers will depend on services provide by the
GRU driver.
The GRU is a hardware resource located in the system chipset. The GRU
contains memory that is mmaped into the user address space. This memory
is used to communicate with the GRU to perform functions such as
load/store, scatter/gather, bcopy, AMOs, etc. The GRU is directly
accessed by user instructions using user virtual addresses. GRU
instructions (ex., bcopy) use user virtual addresses for operands.
The GRU contains a large TLB that is functionally very similar to
processor TLBs. Because the external contains a TLB with user virtual
address, it requires callouts from the core VM system when certain types
of changes are made to the process page tables. There are several MMUOPS
patches currently being discussed but none has been accepted into the
kernel. The GRU driver is built using version V18 from Andrea Arcangeli.
This patch:
Contains the definitions of the hardware GRU data structures that are used
by the driver to manage the GRU.

rtc-dev: stop periodic interrupts on device release
Solves http://bugzilla.kernel.org/show_bug.cgi?id=11127
The old rtc.c driver did it and some drivers (like rtc-sh) do it in their
release function, though they should not -- because they should provide
the irq_set_state op and the rtc framework itself should care about it.
This patch makes it do so.
I am aware that some drivers, like rtc-sh, handle userspace PIE sets in
their ioctl op (instead of having the framework call the op), exporting
the irq_set_state op at the same time. The logic in rtc_irq_set_state
should make sure it doesn't matter and the driver should not need to care
stopping periodic interrupts in its release routine any more.
The correct way, in my opinion, should be this:
1) The driver provides the irq_set_state op and does not care closing the
interrupts in its release op.
2) If the driver does not provide the op and handles PIE in the ioctl op, it's
reponsible for closing them in its release op.
3) Something similar for other IRQs, like UIE -- if there's no in-kernel API
like irq_set_state, handle it in ioctl and release ops. The framework will
be responsible either for everything or for nothing. (This will probably
change later.)

gbefb: cmap FIFO timeout
Writes to the cmap fifo while the display is blanked caused cmap FIFO
timeout messages and a wrong colormap. To avoid this the driver now
maintains a colormap in memory and updates the colormap after the display
is unblanked.

commit fb6624ebd912e3d6907ca6490248e73368223da9 (initrd: Fix virtual/physical
mix-up in overwrite test) introduced the compiler warning below on mips,
as its virt_to_page() doesn't cast the passed address to unsigned long
internally, unlike on most other architectures:
init/main.c: In function `start_kernel':
init/main.c:633: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast
init/main.c:636: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast
For now, kill the warning by explicitly casting initrd_start to `void *', as
that's the type it should really be.

markers: fix markers read barrier for multiple probes
Paul pointed out two incorrect read barriers in the marker handler code in
the path where multiple probes are connected. Those are ordering reads of
"ptype" (single or multi probe marker), "multi" array pointer, and "multi"
array data access.
It should be ordered like this :
read ptype
smp_rmb()
read multi array pointer
smp_read_barrier_depends()
access data referenced by multi array pointer
The code with a single probe connected (optimized case, does not have to
allocate an array) has correct memory ordering.
It applies to kernel 2.6.26.x, 2.6.25.x and linux-next.

cpuset: fix wrong calculation of relax domain level
When multiple cpusets are overlapping in their 'cpus' and hence they
form a single sched domain, the largest sched_relax_domain_level among
those should be used. But when top_cpuset's sched_load_balance is
set, its sched_relax_domain_level is used regardless other sub-cpusets'.
This patch fixes it by walking the cpuset hierarchy to find the largest
sched_relax_domain_level.

sticore: don't activate unsupported GSC STI cards on HPPA
On HPPA there exists some older GSC graphics cards, which need special
graphic-card-BIOS patching to become supported. Since we don't have yet
implemented the patching, it's better to detect such cards in advance,
inform to the user that there are known problems and to not activate the
card.
Problematic GSC cards and BIOS versions are:
* Hyperdrive/Hyperbowl (A4071A) graphics card series:
* ID = 0x2BCB015A (Version 8.04/8)
* ID = 0x2BCB015A (Version 8.04/11)
* Thunder 1 VISUALIZE 48 card:
* ID = 0x2F23E5FC (Version 8.05/9)
* Thunder 2 VISUALIZE 48 XP card:
* ID = 0x2F8D570E (Version 8.05/12)
* Some Hyperion and ThunderHawk GSC cards
Further details are described here:

[MTD] MTD_DEBUG always does compile-time typechecks
The current style for debug messages is to ensure they're always

That way builds won't break only when debug options get enabled,
which is common when they are stripped out early by CPP.
This patch makes CONFIG_MTD_DEBUG adopt that convention.

[MTD] DataFlash: bugfix, binary page sizes now handled
The wrong version of the "teach dataflash about binary density" patch
just got merged (v2 not v3) ... this restores the missing updates:
* Fix the cmdlinepart *regression* that caused testing failures (!!)
by restoring the original part labels in relevant cases.
* Don't reference things that don't exist (!)
- An opcode that doesn't even exist for DataFlash
- The part is "at45db642" not "at45db641"
- ID zero in this JEDEC table
* Make the JEDEC probe routine report and handle errors better:
- If the SPI calls fail, return the error codes.
- Don't depend on ordering of table entries.
- Unrecognized ids are different from parts that have no ID.
We won't actually know how to handle them correctly; display
the ID and ignore the chip.
* Move the original block comment about the "legacy" chip ID scheme
back next to the code to which it applies ... not next to the new
JEDEC query code, which uses an entirely different strategy.
* Don't print a guessed erasesize; /proc/mtd has the real value.
And add a few more comments.

pkt_sched: Fix OOPS on ingress qdisc add.
Bug report from Steven Jan Springl:
Issuing the following command causes a kernel oops:
tc qdisc add dev eth0 handle ffff: ingress
The problem mostly stems from all of the special case handling of
ingress qdiscs.
So, to fix this, do the grafting operation the same way we do for TX
qdiscs. Which means that dev_activate() and dev_deactivate() now do
the "qdisc_sleeping <--> qdisc" transitions on dev->rx_queue too.
Future simplifications are possible now, mainly because it is
impossible for dev_queue->{qdisc,qdisc_sleeping} to be NULL. There
are NULL checks all over to handle the ingress qdisc special case
that used to exist before this commit.

regulator: regulator framework core
This adds the regulator framework core.
This framework is designed to provide a generic interface to voltage
and current regulators within the Linux kernel. It's intended to
provide voltage and current control to client or consumer drivers and
also provide status information to user space applications through a
sysfs interface.
The intention is to allow systems to dynamically control regulator
output in order to save power and prolong battery life. This applies
to both voltage regulators (where voltage output is controllable) and
current sinks (where current output is controllable).
This framework safely compiles out if not selected so that client
drivers can still be used in systems with no software controllable
regulators.

This interface is for machine specific code and allows the creation of
voltage/current domains (with constraints) for each regulator. It can
provide regulator constraints that will prevent device damage through
overvoltage or over current caused by buggy client drivers. It also
allows the creation of a regulator tree whereby some regulators are
supplied by others (similar to a clock tree).

regulator: consumer device interface
Add support to allow consumer device drivers to control their regulator
power supply.
This uses a similar API to the kernel clock interface in that consumer
drivers can get and put a regulator (like they can with clocks atm) and
get/set voltage, current limit, mode, enable and disable. This should
allow consumers complete control over their supply voltage and current
limit. This also compiles out if not in use so drivers can be reused in
systems with no regulator based power control.

The code to handle writes to /proc/ppc64/lparcfg incorrectly
assumes that the return code from the helper routines to update

then assumes any non-hcall return value is bad and sets the return

The update_[mp]pp routines can return values other than a hcall

SELinux: /proc/mounts should show what it can
Given a hosed SELinux config in which a system never loads policy or
disables SELinux we currently just return -EINVAL for anyone trying to
read /proc/mounts. This is a configuration problem but we can certainly
be more graceful. This patch just ignores -EINVAL when displaying LSM
options and causes /proc/mounts display everything else it can. If
policy isn't loaded the obviously there are no options, so we aren't
really loosing any information here.
This is safe as the only other return of EINVAL comes from
security_sid_to_context_core() in the case of an invalid sid. Even if a
FS was mounted with a now invalidated context that sid should have been
remapped to unlabeled and so we won't hit the EINVAL and will work like
we should. (yes, I tested to make sure it worked like I thought)

S2io: fix statistics flush after a MTU change
On s2io driver, when you change the interface MTU, it invokes a card
reset, which flush some statistics. This patch solves this problem, and
also set the net_device->stats as the default statistics structure,
instead of s2io_nic->stats.
To do that, s2io_nic->stats turned into a staging area, where is saved
statistics of the last hardware statistics query. So, the difference
between the current hardware statistics and s2io_nic->stats, is the
value that should be summed up, in order to get the correct statistics
value, even after a reset.

enc28j60: don't specify (wrong) IRQ type
Recent changes to the IRQ framework have made passing the wrong
trigger type to request_irq() become a fatal error. In the case
of the enc28j60 driver, it stopped working in my test harness.
(Specifically: the signal detects "pin change" events, both edges,
not just falling edges. Similarly, other boards might route it
through an inverter. Trigger type are board-specific.)
This fixes that problem by the usual fix of expecting board setup
code to have set up the correct IRQ trigger type. The best known
example of that being x86 setup.

rtl8187: Improve wireless statistics for RTL8187B
Wireless statistics produced by the RTL8187B driver are not particularly
informative about the strength of the received signal. From the data sheet
provided by Realtek, I discovered that certain parts of the RX header
should have the information necessary to calculate signal quality and
strength. With testing, it became clear that most of these quantities were
very jittery - only the AGC correlated with the signals expected from nearby
AP's. As a result, the quality and strength are derived from the agc value.
The scaling has been determined so that the numbers are close to those
obtained by b43 under the same conditions. The results are qualitatively
correct.
Statistics derived for the RTL8187 have not been changed.
The RX header variables have been renamed to match the quantites described
in the Realtek data sheet.

rt2x00: Clear queue entry flags during initialization
When the queues are being initialized the entry flags fields must be
reset to 0. When this does not happen some entries might still be
marked as "occupied" after an ifdown & ifup cycle which would trigger

rt2x00: Force full register config after start()
rt2x00 will only perform configuration changes from
mac80211 when the configuration option has changed.
This means it keeps track of the current active configuration
and will check these values when the config() callback function
is used.
However this causes breakage when the interface has been
brought down and up again, since all stored active values
aren't reset while the registers might have.
This is for example the case with rt61pci antenna registers which
will jump to invalid values when the interface has been started.
To make sure a full configuration takes place after the start()
callback function, a new flag is added which will be checked
during config() and skips the "what's changed" phase.

rt2x00: Fix QOS sequence counting
When IEEE80211_TX_CTL_ASSIGN_SEQ is not set,
the driver should disable hardware sequence counting
to make sure the mac80211 provided counter is used.
This fixes QOS sequence counting, since that is one
of the cases where mac80211 provides a seperate
sequence counter.
By moving the sequence counting code to rt2x00queue
we make sure that _all_ frames get the sequence counter,
including RTS/CTS and Beacon frames.

rt2x00: Fix the beacon length bug
When setting up a beacon template, the length of the beacon is
calculated with the assumption that the SKB already contains

This patch undoes the damage by adding the Tx descriptor length
to the beacon length. This is safe, because the shortest possible
beacon is longer than the Tx header.

rt2x00: Fix EIFS timing value
Olivier reported a difference between the EIFS
values used in the legacy driver and the one in
the rt2x00 drivers.
In rt2x00 the value was
( SIFS + (8 * (IEEE80211_HEADER + ACK_SIZE)) )
which comes down to 314us while the legacy driver uses the value 364us
This was caused because EIFS is: SIFS + DIFS + AckTime
This patch will fix this by adding the DIFS by the above value,
and creating a SHORT_EIFS define which uses the SHORT_DIFS.

rfkill: fix led-trigger unregister order in error unwind
rfkill needs to unregister the led trigger AFTER a call to
rfkill_remove_switch(), otherwise it will not update the LED state,
possibly leaving it ON when it should be OFF.
To make led-trigger unregistering safer, guard against unregistering a
trigger twice, and also against issuing trigger events to a led trigger
that was unregistered. This makes the error unwind paths more resilient.
Refer to "rfkill: Register LED triggers before registering switch".

Ath5k: fix memory corruption
When signal is noisy, hardware can use all RX buffers and since the last
entry in the list is self-linked, it overwrites the entry until we link
new buffers.
Ensure that we don't free this last one until we are 100% sure that it
is not used by the hardware anymore to not cause memory curruption as
can be seen below.
This is done by checking next buffer in the list. Even after that we
know that the hardware refetched the new link and proceeded further
(the next buffer is ready) we can finally free the overwritten buffer.
We discard it since the status in its descriptor is overwritten (OR-ed
by new status) too.

ALSA: asoc: restrict sample rate and size in Freescale MPC8610 sound drivers
The Freescale MPC8610 SSI device has the option of using one clock for both
transmit and receive (synchronous mode), or independent clocks (asynchronous).
The SSI driver, however, programs the SSI into synchronous mode and then
tries to program the clock registers independently. The result is that the wrong
sample size is usually generated during recording.
This patch fixes the discrepancy by restricting the sample rate and sample size
of the playback and capture streams. The SSI driver remembers which stream
is opened first. When a second stream is opened, that stream is constrained
to the same sample rate and size as the first stream.
A future version of this driver will lift the sample size restriction.
Supporting independent sample rates is more difficult, because only certain
codecs provide dual independent clocks.

Fix 'get_user_pages_fast()' with non-page-aligned start address
Alexey Dobriyan reported trouble with LTP with the new fast-gup code,
and Johannes Weiner debugged it to non-page-aligned addresses, where the
new get_user_pages_fast() code would do all the wrong things, including
just traversing past the end of the requested area due to 'addr' never
matching 'end' exactly.
This is not a pretty fix, and we may actually want to move the alignment
into generic code, leaving just the core code per-arch, but Alexey
verified that the vmsplice01 LTP test doesn't crash with this.

md: do not count blocked devices as spares
remove_and_add_spares() assumes that failed devices have been hot-removed

lguest: turn Waker into a thread, not a process
lguest uses a Waker process to break it out of the kernel (ie.
actually running the guest) when file descriptor needs attention.
Changing this from a process to a thread somewhat simplifies things:
it can directly access the fd_set of things to watch. More
importantly, it means that the Waker can see Guest memory correctly,
so /dev/vring file descriptors will work as anticipated (the
alternative is to actually mmap MAP_SHARED, but you can't do that with
/dev/zero).

lguest: Support assigning a MAC address
If you've got a nice DHCP configuration which maps MAC
addresses to specific IP addresses, then you're going to
want to start your guest with one of those MAC addresses.
Also, in Fedora, we have persistent network interface naming
based on the MAC address, so with randomly assigned
addresses you're soon going to hit eth13. Who knows what
will happen then!
Allow assigning a MAC address to the network interface with
e.g.
--tunnet=bridge:eth0:00:FF:95:6B:DA:3D
or:
--tunnet=192.168.121.1:00:FF:95:6B:DA:3D
which is pretty unintelligable, but ...

eCryptfs: use page_alloc not kmalloc to get a page of memory
With SLUB debugging turned on in 2.6.26, I was getting memory corruption
when testing eCryptfs. The root cause turned out to be that eCryptfs was
doing kmalloc(PAGE_CACHE_SIZE); virt_to_page() and treating that as a nice
page-aligned chunk of memory. But at least with SLUB debugging on, this
is not always true, and the page we get from virt_to_page does not
necessarily match the PAGE_CACHE_SIZE worth of memory we got from kmalloc.
My simple testcase was 2 loops doing "rm -f fileX; cp /tmp/fileX ." for 2
different multi-megabyte files. With this change I no longer see the
corruption.

vfs: pagecache usage optimization for pagesize!=blocksize
When we read some part of a file through pagecache, if there is a
pagecache of corresponding index but this page is not uptodate, read IO
is issued and this page will be uptodate.
I think this is good for pagesize == blocksize environment but there is
room for improvement on pagesize != blocksize environment. Because in
this case a page can have multiple buffers and even if a page is not
uptodate, some buffers can be uptodate.
So I suggest that when all buffers which correspond to a part of a file
that we want to read are uptodate, use this pagecache and copy data from
this pagecache to user buffer even if a page is not uptodate. This can
reduce read IO and improve system throughput.
I wrote a benchmark program and got result number with this program.
This benchmark do:
1: mount and open a test file.
2: create a 512MB file.
3: close a file and umount.
4: mount and again open a test file.
5: pwrite randomly 300000 times on a test file. offset is aligned
by IO size(1024bytes).
6: measure time of preading randomly 100000 times on a test file.
The result was:
2.6.26
330 sec
2.6.26-patched
226 sec
Arch:i386
Filesystem:ext3
Blocksize:1024 bytes
Memory: 1GB
On ext3/4, a file is written through buffer/block. So random read/write
mixed workloads or random read after random write workloads are optimized
with this patch under pagesize != blocksize environment. This test result
showed this.
The benchmark program is as follows:
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
#include <time.h>

spi_s3c24xx: really assign busnum
The original "Pass the bus number we expect the S3C24XX SPI driver to
attach to via the platform data." [1] patch was mis-sent, and missed two
important parts of the diff, which was to actually set the bus_num field
and add the relevant field to the platform data.
The previous commit 50f426b55d919dd017af35bb6a08753d1f262920 promised to
add a bus_num field, but failed to include the two hunks that added this
field to include/asm-arm/arch-s3c2410/spi.h and then pass it to the spi
core when creating the new master field in drivers/spi/spi_s3c24xx.c.

mpc52xx_psc_spi: fix block transfer
The block transfer routine in the mpc52xx psc spi driver misinterpret
the datasheet. According to the processor datasheet the chipselect is
held as long as the EOF is not written.
Theoretically blocks of any sizes can be transferred in this way. The
old routine however writes an EOF after every word, which has the size
of size_of_word. This makes the transfer slow.
Also fixed some duplicate code.

mmu-notifiers: core
With KVM/GFP/XPMEM there isn't just the primary CPU MMU pointing to pages.
There are secondary MMUs (with secondary sptes and secondary tlbs) too.
sptes in the kvm case are shadow pagetables, but when I say spte in
mmu-notifier context, I mean "secondary pte". In GRU case there's no
actual secondary pte and there's only a secondary tlb because the GRU
secondary MMU has no knowledge about sptes and every secondary tlb miss
event in the MMU always generates a page fault that has to be resolved by
the CPU (this is not the case of KVM where the a secondary tlb miss will
walk sptes in hardware and it will refill the secondary tlb transparently
to software if the corresponding spte is present). The same way
zap_page_range has to invalidate the pte before freeing the page, the spte
(and secondary tlb) must also be invalidated before any page is freed and
reused.
Currently we take a page_count pin on every page mapped by sptes, but that
means the pages can't be swapped whenever they're mapped by any spte
because they're part of the guest working set. Furthermore a spte unmap
event can immediately lead to a page to be freed when the pin is released
(so requiring the same complex and relatively slow tlb_gather smp safe
logic we have in zap_page_range and that can be avoided completely if the
spte unmap event doesn't require an unpin of the page previously mapped in
the secondary MMU).
The mmu notifiers allow kvm/GRU/XPMEM to attach to the tsk->mm and know
when the VM is swapping or freeing or doing anything on the primary MMU so
that the secondary MMU code can drop sptes before the pages are freed,
avoiding all page pinning and allowing 100% reliable swapping of guest
physical address space. Furthermore it avoids the code that teardown the
mappings of the secondary MMU, to implement a logic like tlb_gather in
zap_page_range that would require many IPI to flush other cpu tlbs, for
each fixed number of spte unmapped.
To make an example: if what happens on the primary MMU is a protection
downgrade (from writeable to wrprotect) the secondary MMU mappings will be
invalidated, and the next secondary-mmu-page-fault will call
get_user_pages and trigger a do_wp_page through get_user_pages if it
called get_user_pages with write=1, and it'll re-establishing an updated
spte or secondary-tlb-mapping on the copied page. Or it will setup a
readonly spte or readonly tlb mapping if it's a guest-read, if it calls
get_user_pages with write=0. This is just an example.
This allows to map any page pointed by any pte (and in turn visible in the
primary CPU MMU), into a secondary MMU (be it a pure tlb like GRU, or an
full MMU with both sptes and secondary-tlb like the shadow-pagetable layer
with kvm), or a remote DMA in software like XPMEM (hence needing of
schedule in XPMEM code to send the invalidate to the remote node, while no
need to schedule in kvm/gru as it's an immediate event like invalidating
primary-mmu pte).
At least for KVM without this patch it's impossible to swap guests
reliably. And having this feature and removing the page pin allows
several other optimizations that simplify life considerably.
Dependencies:
1) mm_take_all_locks() to register the mmu notifier when the whole VM
isn't doing anything with "mm". This allows mmu notifier users to keep
track if the VM is in the middle of the invalidate_range_begin/end
critical section with an atomic counter incraese in range_begin and
decreased in range_end. No secondary MMU page fault is allowed to map
any spte or secondary tlb reference, while the VM is in the middle of
range_begin/end as any page returned by get_user_pages in that critical
section could later immediately be freed without any further
->invalidate_page notification (invalidate_range_begin/end works on
ranges and ->invalidate_page isn't called immediately before freeing
the page). To stop all page freeing and pagetable overwrites the
mmap_sem must be taken in write mode and all other anon_vma/i_mmap
locks must be taken too.
2) It'd be a waste to add branches in the VM if nobody could possibly
run KVM/GRU/XPMEM on the kernel, so mmu notifiers will only enabled if
CONFIG_KVM=m/y. In the current kernel kvm won't yet take advantage of
mmu notifiers, but this already allows to compile a KVM external module
against a kernel with mmu notifiers enabled and from the next pull from
kvm.git we'll start using them. And GRU/XPMEM will also be able to
continue the development by enabling KVM=m in their config, until they
submit all GRU/XPMEM GPLv2 code to the mainline kernel. Then they can
also enable MMU_NOTIFIERS in the same way KVM does it (even if KVM=n).
This guarantees nobody selects MMU_NOTIFIER=y if KVM and GRU and XPMEM
are all =n.
The mmu_notifier_register call can fail because mm_take_all_locks may be
interrupted by a signal and return -EINTR. Because mmu_notifier_reigster
is used when a driver startup, a failure can be gracefully handled. Here
an example of the change applied to kvm to register the mmu notifiers.
Usually when a driver startups other allocations are required anyway and
-ENOMEM failure paths exists already.
struct kvm *kvm_arch_create_vm(void)
{
struct kvm *kvm = kzalloc(sizeof(struct kvm), GFP_KERNEL);
+ int err;
if (!kvm)
return ERR_PTR(-ENOMEM);
INIT_LIST_HEAD(&kvm->arch.active_mmu_pages);
+ kvm->arch.mmu_notifier.ops = &kvm_mmu_notifier_ops;
+ err = mmu_notifier_register(&kvm->arch.mmu_notifier, current->mm);
+ if (err) {
+ kfree(kvm);
+ return ERR_PTR(err);
+ }
+
return kvm;
}
mmu_notifier_unregister returns void and it's reliable.
The patch also adds a few needed but missing includes that would prevent
kernel to compile after these changes on non-x86 archs (x86 didn't need
them by luck).

mmu-notifiers: add mm_take_all_locks() operation
mm_take_all_locks holds off reclaim from an entire mm_struct. This allows
mmu notifiers to register into the mm at any time with the guarantee that
no mmu operation is in progress on the mm.
This operation locks against the VM for all pte/vma/mm related operations
that could ever happen on a certain mm. This includes vmtruncate,
try_to_unmap, and all page faults.
The caller must take the mmap_sem in write mode before calling
mm_take_all_locks(). The caller isn't allowed to release the mmap_sem
until mm_drop_all_locks() returns.
mmap_sem in write mode is required in order to block all operations that
could modify pagetables and free pages without need of altering the vma
layout (for example populate_range() with nonlinear vmas). It's also
needed in write mode to avoid new anon_vmas to be associated with existing
vmas.
A single task can't take more than one mm_take_all_locks() in a row or it
would deadlock.
mm_take_all_locks() and mm_drop_all_locks are expensive operations that
may have to take thousand of locks.
mm_take_all_locks() can fail if it's interrupted by signals.
When mmu_notifier_register returns, we must be sure that the driver is
notified if some task is in the middle of a vmtruncate for the 'mm' where
the mmu notifier was registered (mmu_notifier_invalidate_range_start/end
is run around the vmtruncation but mmu_notifier_register can run after
mmu_notifier_invalidate_range_start and before
mmu_notifier_invalidate_range_end). Same problem for rmap paths. And
we've to remove page pinning to avoid replicating the tlb_gather logic
inside KVM (and GRU doesn't work well with page pinning regardless of
needing tlb_gather), so without mm_take_all_locks when vmtruncate frees
the page, kvm would have no way to notice that it mapped into sptes a page
that is going into the freelist without a chance of any further
mmu_notifier notification.

tmpfs: fix kernel BUG in shmem_delete_inode
SuSE's insserve initscript ordering program hits kernel BUG at mm/shmem.c:814
on 2.6.26. It's using posix_fadvise on directories, and the shmem_readpage
method added in 2.6.23 is letting POSIX_FADV_WILLNEED allocate useless pages
to a tmpfs directory, incrementing i_blocks count but never decrementing it.
Fix this by assigning shmem_aops (pointing to readpage and writepage and
set_page_dirty) only when it's needed, on a regular file or a long symlink.
Many thanks to Kel for outstanding bugreport and steps to reproduce it.

PCI: disable ASPM per ACPI FADT setting
The ACPI FADT table includes an ASPM control bit. If the bit is set, do
not enable ASPM since it may indicate that the platform doesn't actually

PCI MSI: Don't disable MSIs if the mask bit isn't supported
David Vrabel has a device which generates an interrupt storm on the INTx
pin if we disable MSI interrupts altogether. Masking interrupts is only
a performance optimisation, so we can ignore the request to mask the
interrupt.

sh: Fix up unaligned current_text_addr().
As noted by Adrian:
Commit 3ab83521378268044a448113c6aa9a9e245f4d2f (kexec jump)
causes the following build error on sh:
<-- snip -->
...
CC kernel/kexec.o
{standard input}: Assembler messages:
{standard input}:1518: Error: offset to unaligned destination
make[2]: *** [kernel/kexec.o] Error 1
<-- snip -->
If I understand the assembler correctly it fails at
include/asm-sh/kexec.h:59
The issue here is that the mova reference lacks an explicit alignment,
and previous code paths would end up with this on a 16-bit boundary,
so we make the alignment explicit.

PCI: handle 64-bit resources better on 32-bit machines
If the kernel is configured to support 64-bit resources on a 32-bit
machine, we can support 64-bit BARs properly. Just change the condition
to check sizeof(resource_size_t) instead of BITS_PER_LONG.

cpu masks: optimize and clean up cpumask_of_cpu()
Clean up and optimize cpumask_of_cpu(), by sharing all the zero words.
Instead of stupidly generating all possible i=0...NR_CPUS 2^i patterns
creating a huge array of constant bitmasks, realize that the zero words
can be shared.
In other words, on a 64-bit architecture, we only ever need 64 of these
arrays - with a different bit set in one single world (with enough zero
words around it so that we can create any bitmask by just offsetting in
that big array). And then we just put enough zeroes around it that we
can point every single cpumask to be one of those things.
So when we have 4k CPU's, instead of having 4k arrays (of 4k bits each,
with one bit set in each array - 2MB memory total), we have exactly 64
arrays instead, each 8k bits in size (64kB total).
And then we just point cpumask(n) to the right position (which we can
calculate dynamically). Once we have the right arrays, getting
"cpumask(n)" ends up being:
static inline const cpumask_t *get_cpu_mask(unsigned int cpu)
{
const unsigned long *p = cpu_bit_bitmap[1 + cpu % BITS_PER_LONG];
p -= cpu / BITS_PER_LONG;
return (const cpumask_t *)p;
}
This brings other advantages and simplifications as well:
- we are not wasting memory that is just filled with a single bit in
various different places
- we don't need all those games to re-create the arrays in some dense
format, because they're already going to be dense enough.
if we compile a kernel for up to 4k CPU's, "wasting" that 64kB of memory
is a non-issue (especially since by doing this "overlapping" trick we
probably get better cache behaviour anyway).

Converted Linus's mails into a commit. See:
http://lkml.org/lkml/2008/7/27/156
http://lkml.org/lkml/2008/7/28/320
Also applied a family filter - which also has the side-effect of leaving
out the bits where Linus calls me an idio... Oh, never mind ;-)

ACPI/CPUIDLE: prevent setting pm_idle to NULL
pm_idle_save resp. pm_idle_old can be NULL when the restore code in
acpi_processor_cst_has_changed() resp. cpuidle_uninstall_idle_handler()
is called. This can set pm_idle unconditinally to NULL, which causes the
kernel to panic when calling pm_idle in the x86 idle code. This was
covered by an extra check for !pm_idle in the x86 idle code, which was
removed during the x86 idle code refactoring.
Instead of restoring the pm_idle check in the x86 code prevent the
acpi/cpuidle code to set pm_idle to NULL.

ipwireless: Increase PPP outgoing queue size
ipwireless: Increase PPP outgoing queue size
Increase default size of PPP outgoing queue. Currently set to 1, which
means that a packet quickly following another pushed by PPP must wait
until hardware actually sends the previous and PPP has to be waken up
by ppp_wakeup(). This slows down upstream.
Now PPP can push more packets at once which get buffered inside driver
and pushed immediatelly to hardware when previous packet is out.
Experiments show that size = 10 is quite good for all connection types
(GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads.
Need for higher queue size than 10 occures in only < 0.1 % of cases.

cpm2: Rework baud rate generators configuration to support external clocks.
The CPM2 BRG setup functions cpm_setbrg and cpm2_fastbrg don't support
external clocks. This patch adds a new exported __cpm2_setbrg function
that takes the clock rate and clock source as extra parameters, and moves
cpm_setbrg and cpm2_fastbrg to include/asm-powerpc/cpm2.h where they
become inline wrappers around __cpm2_setbrg.

powerpc: rtc_cmos_setup: assign interrupts only if there is i8259 PIC
i8259 PIC is disabled on MPC8610HPCD boards, thus currently rtc-cmos
driver fails to probe.
To fix the issue, we lookup the device tree for "chrp,iic" and
"pnpPNP,000" compatible devices, and if not found we do not assign RTC
IRQ and assuming that i8259 was disabled.
Though this patch fixes RTC on some boards (and surely should not break
any other), the whole approach is still broken. We can't easily fix this
though, because old device trees do not specify i8259 interrupts for the
cmos rtc node.

i2c: S3C2410: Pass the I2C bus number via drivers platform data
Allow the platform data to specify the bus bumber that the
new I2C bus will be given. This is to allow the use of the
board registration mechanism to specify the new style of
I2C device registration which allows boards to provide a
list of attached devices.
Note, as discussed on the mailing list, we have dropped
backwards compatibility of adding an dynamic bus number
as it should not affect most boards to have the bus pinned
to 0 if they have either not specified platform data for
driver. Any board supplying platform data will automatically
have the bus_num field set to 0, and anyone who needs the
driver on a different bus number can supply platform data
to set bus_num.

sh: Workaround for __put_user_asm() bug with gcc 4.x on big-endian.
I think this problem is GCC(4.1.2) bug.
Syscall "getdents" returned "dirent->d_off" is always 0.
I think other EB enviroment have same problem.
Problem code
0c03c954 <filldir>:
:
c03c97a: 58 f7 mov.l @(28,r15),r8 !-> offset (high)
c03c97c: 59 f8 mov.l @(32,r15),r9 !-> offset (low)
c03c97e: 53 f9 mov.l @(36,r15),r3
c03c980: 54 fa mov.l @(40,r15),r4
:
c03c9a0: 21 82 mov.l r8, at r1 !offset(high) -> dirent->d_off

sh: Conditionally re-enable IRQs in fault path.
The current kernel behaviour is to reenable interrupts unconditionally
when taking a page fault. This patch changes this to only enable them
if interrupts were previously enabled.
It also fixes a problem seen with this fix in place: the kernel previously
flushed the vsyscall page when handling a signal, which is not only
unncessary, but caused a possible sleep with interrupts disabled.

binfmt_elf_fdpic: Magical stack pointer index, for NEW_AUX_ENT compat.
While implementing binfmt_elf_fdpic on SH it quickly became apparent
that SH was the first platform to support both binfmt_elf_fdpic and
binfmt_elf, as well as the only of the FDPIC platforms to make use of the
auxvt.
Currently binfmt_elf_fdpic uses a special version of NEW_AUX_ENT() where
the first argument is the entry displacement after csp has been adjusted,
being reset after each adjustment. As we have no ability to sort this out
through the platform's ARCH_DLINFO, this index needs to be managed
entirely in create_elf_fdpic_tables(). Presently none of the platforms
that set their own auxvt entries are able to do so through their
respective ARCH_DLINFOs when using binfmt_elf_fdpic.
In addition to this, binfmt_elf_fdpic has been looking at
DLINFO_ARCH_ITEMS for the number of architecture-specific entries in the
auxvt. This is legacy cruft, and is not defined by any platforms in-tree,
even those that make heavy use of the auxvt. AT_VECTOR_SIZE_ARCH is
always available, and contains the number that is of interest here, so we
switch to using that unconditionally as well.
As this has direct bearing on how much stack is used, platforms that have
configurable (or dynamically adjustable) NEW_AUX_ENT calls need to either
make AT_VECTOR_SIZE_ARCH more fine-grained, or leave it as a worst-case
and live with some lost stack space if those entries aren't pushed (some
platforms may also need to purposely sacrifice some space here for
alignment considerations, as noted in the code -- although not an issue
for any FDPIC-capable platform today).

[XFS] xfs_setattr currently doesn't just handle the attributes set through

eating up stackspace.
This patch adds a new xfs_ioctl_setattr helper for the XFS ioctls that set
these attributes and remove the code to set them through xfs_setattr.

[XFS] fix mount option parsing in remount
Remount currently happily accept any option thrown at it, although the
only filesystem specific option it actually handles is barrier/nobarrier.
And it actually doesn't handle these correctly either because it only uses
the value it parsed when we're doing a ro->rw transition. In addition to
that there's also a bad bug in xfs_parseargs which doesn't touch the
actual option in the mount point except for a single one,
XFS_MOUNT_SMALL_INUMS and thus forced any filesystem that's every
remounted in some way to not support 64bit inodes with no way to recover
unless unmounted.
This patch changes xfs_fs_remount to use it's own linux/parser.h based
options parse instead of xfs_parseargs and reject all options except for
barrier/nobarrier and to the right thing in general. Eventually I'd like
to have a single big option table used for mount aswell but that can wait
for a while.

[XFS] Disable queue flag test in barrier check.
md raid1 can pass down barriers, but does not set an ordered flag on the
queue, so xfs does not even attempt a barrier write, and will never use
barriers on these block devices.
Remove the flag check and just let the barrier write test determine
barrier support.
A possible risk here is that if something does not set an ordered flag and
also does not properly return an error on a barrier write... but if it's
any consolation jbd/ext3/reiserfs never test the flag, and don't even do a
test write, they just disable barriers the first time an actual journal
barrier write fails.

[XFS] streamline init/exit path
Currently the xfs module init/exit code is a mess. It's farmed out over a
lot of function with very little error checking. This patch makes sure we
propagate all initialization failures properly and clean up after them.
Various runtime initializations are replaced with compile-time
initializations where possible to make this easier. The exit path is
similarly consolidated.
There's now split out function to create/destroy the kmem zones and
alloc/free the trace buffers. I've also changed the ktrace allocations to
KM_MAYFAIL and handled errors resulting from that.
And yes, we really should replace the XFS_*_TRACE ifdefs with a single
XFS_TRACE..

This doesn't make any sense, is not mentioned in the standards and not
performed by any other Linux filesystems so remove it.

[XFS] Restore the lowspace extent allocator algorithm
When free space is running low the extent allocator may choose to allocate
an extent from an AG without leaving sufficient space for a btree split
when inserting the new extent (see where xfs_bmap_btalloc() sets minleft
to 0). In this case the allocator will enable the lowspace algorithm which
is supposed to allow further allocations (such as btree splits and
newroots) to allocate from sequential AGs. This algorithm has been broken
for a long time and this patch restores its behaviour.

[XFS] use minleft when allocating in xfs_bmbt_split()
The bmap btree split code relies on a previous data extent allocation
(from xfs_bmap_btalloc()) to find an AG that has sufficient space to
perform a full btree split, when inserting the extent. When converting
unwritten extents we don't allocate a data extent so a btree split will be
the first allocation. In this case we need to set minleft so the allocator
will pick an AG that has space to complete the split(s).

[XFS] attrmulti cleanup
xfs_attrmulti_by_handle currently request the size based on
sizeof(attr_multiop_t) but should be using sizeof(xfs_attr_multiop_t)
because that is what it is dealing with. Despite beeing wrong this
actually harmless in practice because both structures are the same size on
all platforms.
But this sizeof was the only user of struct attr_multiop so we can just
kill it. Also move the ATTR_OP_* defines xfs_attr.h into the struct
xfs_attr_multiop defintion in xfs_fs.h because they are only used with
that structure, and are part of the user ABI for the
XFS_IOC_ATTRMULTI_BY_HANDLE ioctl.

[XFS] Fix returning case-preserved name with CI node form directories
xfs_dir2_node_lookup() calls xfs_da_node_lookup_int() which iterates
through leaf blocks containing the matching hash value for the name being
looked up. Inside xfs_da_node_lookup_int(), it calls the
xfs_dir2_leafn_lookup_for_entry() for each leaf block.
xfs_dir2_leafn_lookup_for_entry() iterates through each matching
hash/offset pair doing a name comparison to find the matching dirent.
For CI mode, the state->extrablk retains the details of the block that has
the CI match so xfs_dir2_node_lookup() can return the case-preserved name.
The original implementation didn't retain the xfs_da_buf_t properly, so
the lookup was returning a bogus name to be stored in the dentry.
In the case of unlink, the bad name was passed and in debug mode, ASSERTed
when it can't find the entry.

needs to index past the extents, that were copied to the previous page,
and move the remaining extents. For pages that are already full (ie
ext_avail == 0) the compaction code has no net effect so don't do it.

[XFS] Pack some shortform dir2 structures for the ARM old ABI
architecture.
This should fix the longstanding issues with xfs and old ABI arm boxes,
which lead to various asserts and xfs shutdowns, and for which an
(incorrect) patch has been floating around for years.
I've verified this patch by comparing the on-disk structure layouts using
pahole from the dwarves package, as well as running through a bit of xfsqa
under qemu-arm, modified so that the check/repair phase after each test
actually executes check/repair from the x86 host, on the filesystem
populated by the arm emulator. Thus far it all looks good.
There are 2 other structures with extra padding at the end, but they don't
seem to cause trouble. I suppose they could be packed as well:
xfs_dir2_data_unused_t and xfs_dir2_sf_t.
Note that userspace needs a similar treatment, and any filesystems which
were running with the previous rogue "fix" will now see corruption (either
in the kernel, or during xfs_repair) with this fix properly in place; it
may be worth teaching xfs_repair to identify and fix that specific issue.

[XFS] XFS: ASCII case-insensitive support
Implement ASCII case-insensitive support. It's primary purpose is for
supporting existing filesystems that already use this case-insensitive
mode migrated from IRIX. But, if you only need ASCII-only case-insensitive
support (ie. English only) and will never use another language, then this
mode is perfectly adequate.
ASCII-CI is implemented by generating hashes based on lower-case letters
and doing lower-case compares. It implements a new xfs_nameops vector for
doing the hashes and comparisons for all filename operations.
To create a filesystem with this CI mode, use: # mkfs.xfs -n version=ci

[XFS] Return case-insensitive match for dentry cache
This implements the code to store the actual filename found during a
lookup in the dentry cache and to avoid multiple entries in the dcache
pointing to the same inode.
To avoid polluting the dcache, we implement a new directory inode
operations for lookup. xfs_vn_ci_lookup() stores the correct case name in
the dcache.
The "actual name" is only allocated and returned for a case- insensitive
match and not an actual match.
Another unusual interaction with the dcache is not storing negative
dentries like other filesystems doing a d_add(dentry, NULL) when an ENOENT
is returned. During the VFS lookup, if a dentry returned has no inode,
dput is called and ENOENT is returned. By not doing a d_add, this actually
removes it completely from the dcache to be reused. create/rename have to
be modified to support unhashed dentries being passed in.

[XFS] Name operation vector for hash and compare
Adds two pieces of functionality for the basis of case-insensitive support
in XFS:
1. A comparison result enumerated type: xfs_dacmp. It represents an
exact match, case-insensitive match or no match at all. This patch
only implements different and exact results.
2. xfs_nameops vector for specifying how to perform the hash generation
of filenames and comparision methods. In this patch the hash vector
points to the existing xfs_da_hashname function and the comparison
method does a length compare, and if the same, does a memcmp and
return the xfs_dacmp result.
All filename functions that use the hash (create, lookup remove, rename,
etc) now use the xfs_nameops.hashname function and all directory lookup
functions also use the xfs_nameops.compname function.
The lookup functions also handle case-insensitive results even though the
default comparison function cannot return that. And important aspect of
the lookup functions is that an exact match always has precedence over a
case-insensitive. So while a case-insensitive match is found, we have to
keep looking just in case there is an exact match. In the meantime, the
info for the first case-insensitive match is retained if no exact match is
found.

de-duplicate calls to xfs_attr_trace_enter
Every call to xfs_attr_trace_enter() shares the exact same 16 args in the
middle... just send in the context pointer and let the next level down
split it into the ktrace.
Compile tested only.

[XFS] sort out opening and closing of the block devices
Currently closing the rt/log block device is done in the wrong spot, and
far too early. So revampt it:
- xfs_blkdev_put moved out of xfs_free_buftarg into the caller so that
it is done after tearing down the buftarg completely.
- call to xfs_unmountfs_close moved from xfs_mountfs into caller so
that it's done after tearing down the filesystem completely.
- xfs_unmountfs_close is renamed to xfs_close_devices and made static
in xfs_super.c
- opening of the block devices is split into a helper xfs_open_devices
that is symetric in use to xfs_close_devices
- xfs_unmountfs can now lose struct cred
- error handling around device opening sanitized in xfs_fs_fill_super

xfs_unmount is small and already pretty Linux specific, so merge it into

WARN_ON on the xfs_unmount_flush retval directly instead of propagating
the error back to the caller, and the mout failure case in simplified
significantly by removing the forced shutdown case and all the dmapi
events that shouldn't be sent because the dmapi mount event hasn't been
sent by that time either.

[XFS] Convert l_flushsema to a sv_t
The l_flushsema doesn't exactly have completion semantics, nor mutex
semantics. It's used as a list of tasks which are waiting to be notified
that a flush has completed. It was also being used in a way that was
potentially racy, depending on the semaphore implementation.
By using a sv_t instead of a semaphore we avoid the need for a separate
counter, since we know we just need to wake everything on the queue.
Original waitqueue implementation from Matthew Wilcox. Cleanup and
conversion to sv_t by Christoph Hellwig.

The 64K SPU local store mapping feature is incompatible with the

the memory management to differenciate between them while they
use a different page table format.
For now, disable 64K huge pages when CONFIG_SPU_FS_64K_LS,
in the long run, this can be fixed by making this feature use
the hugetlb page table format.

powerpc/powermac: Use sane default baudrate for SCC debugging
When using the "sccdbg" option to route early kernel messages and
xmon to the SCC serial port on PowerMacs, when this wasn't the
configured output port of Open Firmware, we initialize the baudrate
to 57600bps. This isn't a very good default on some powermacs where
both the FW and pmac_zilog will default to 38400. This fixes it to
use the same logic as pmac_zilog to pick a default speed.

powerpc: Show processor cache information in sysfs
Collect cache information from the OF device tree and display it in
the cpu hierarchy in sysfs. This is intended to be compatible at the
userspace level with x86's implementation[1], hence some of the funny
attribute names. The arrangement of cache info is not immediately
intuitive, but (again) it's for compatibility's sake.
The cache attributes exposed are:
type (Data, Instruction, or Unified)
level (1, 2, 3...)
size
coherency_line_size
number_of_sets
ways_of_associativity
All of these can be derived on platforms that follow the OF PowerPC
Processor binding. The code "publishes" only those attributes for
which it is able to determine values; attributes for values which
cannot be determined are not created at all.

powerpc: Call tracehook_signal_handler() when setting up signal frames
This makes the powerpc signal handling code call tracehook_signal_handler()
after a handler is set up. This means that using PTRACE_SINGLESTEP to
enter a signal handler will report to ptrace on the first instruction of
the handler, instead of the second. This is consistent with what x86 and
other machines do, and what users and debuggers want.

powerpc: Update cpu_sibling_maps dynamically
Rather doing one initialization pass over all the per-cpu
cpu_sibling_maps at boot, update the maps at cpu online/offline time.
This is a behavior change -- the thread_siblings attribute now
reflects only online siblings, whereas it would display offline
siblings before. The new behavior matches that of x86, and is
arguably more useful.

powerpc: kill useless SMT code in prom_hold_cpus
This piece of code is broken for >2 threads, and possibly in some

"ibm,ppc-interrupt-server#s" property to a value obtained from a
"reg" property) and doesn't seem to have any useful purpose in the
first place other than a dubious warning in case NR_CPUS is too
small, which probably isn't the right place to do so.

stop_machine(): stop_machine_run() changed to use cpu mask
Instead of a "cpu" arg with magic values NR_CPUS (any cpu) and ~0 (all
cpus), pass a cpumask_t. Allow NULL for the common case (where we
don't care which CPU the function is run on): temporary cpumask_t's
are usually considered bad for stack space.
This deprecates stop_machine_run, to be removed soon when all the
callers are dead.

Hotplug CPU: don't check cpu_online after take_cpu_down
Akinobu points out that if take_cpu_down() succeeds, the cpu must be offline.
Remove the cpu_online() check, and put a BUG_ON().
Quoting Akinobu Mita:
Actually the cpu_online() check was necessary before appling this
stop_machine: simplify patch.
With old __stop_machine_run(), __stop_machine_run() could succeed
(return !IS_ERR(p) value) even if take_cpu_down() returned non-zero value.
The return value of take_cpu_down() was obtained through kthread_stop()..

In file included from drivers/media/common/tuners/mxl5007t.c:25:drivers/media/common/tuners/mxl5007t.h:80:1: warning: "CONFIG_MEDIA_TUNER_MXL5007T" redefined
In file included from <command-line>:0:
./include/linux/autoconf.h:2782:1: warning: this is the location of the previous definition
Probably, some temporary hack for testing.

NFS: Ensure we call nfs_sb_deactive() after releasing the directory inode
In order to avoid the "Busy inodes after unmount" error message, we need to
ensure that nfs_async_unlink_release() releases the super block after the
call to nfs_free_unlinkdata().

/etc/rc6.d/S60umountroot: line 17: 1462 Segmentation fault mount $MOUNT_FORCE_OPT -n -o remount,ro -t dummytype dummydev / 2> /dev/null
The new super.c:nfs_remount function doesn't check the validity of the
options/options4 pointers. Unfortunately, this seems to happend.
The obvious patch seems to check the pointers, and not to do anything if
the happend to be NULL.
Tested on an XScale PXA255 system, latest git.

M.

V4L/DVB (8546): saa7146: fix read from uninitialized memory
The offset field of the scatterlist entry *after* the last valid scatterlist
entry was used instead of the first scatterlist entry (as was the intention
of this code).
This worked fine until the kzalloc of the sglist was replaced with kmalloc
and sg_init_table only zeroed the exact needed length. Apparently kzalloc
zeroes a bit more than is strictly necessary so the offset field was
always 0 in the past.
But now the offset field was suddenly random and this led to broken captures.

sparc, sparc64: use arch/sparc/include
The majority of this patch was created by the following script:
***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***
The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.

missing bits of net-namespace / sysctl
Piss-poor sysctl registration API strikes again, film at 11...
What we really need is _pathname_ required to be present in already
registered table, so that kernel could warn about bad order. That's the
next target for sysctl stuff (and generally saner and more explicit
order of initialization of ipv[46] internals wouldn't hurt either).
For the time being, here are full fixups required by ..._rotable()
stuff; we make per-net sysctl sets descendents of "ro" one and make sure
that sufficient skeleton is there before we start registering per-net
sysctls.

[SCSI] extend the last_sector_bug flag to cover more sectors
The last_sector_bug flag was added to work around a bug in certain usb
cardreaders, where they would crash if a multiple sector read included the
last sector. The original implementation avoids this by e.g. splitting an 8
sector read which includes the last sector into a 7 sector read, and a single
sector read for the last sector. The flag is enabled for all USB devices.
This revealed a second bug in other usb cardreaders, which crash when they
get a multiple sector read which stops 1 sector short of the last sector.
Affected hardware includes the Kingston "MobileLite" external USB cardreader
and the internal USB cardreader on the Asus EeePC.
Extend the last_sector_bug workaround to ensure that any access which touches
the last 8 hardware sectors of the device is a single sector long. Requests
are shrunk as necessary to meet this constraint.
This gives us a safety margin against potential unknown or future bugs
affecting multi-sector access to the end of the device. The two known bugs
only affect the last 2 sectors. However, they suggest that these devices
are prone to fencepost errors and that multi-sector access to the end of the
device is not well tested. Popular OS's use multi-sector accesses, but they
rarely read the last few sectors. Linux (with udev & vol_id) automatically
reads sectors from the end of the device on insertion. It is assumed that
single sector accesses are more thoroughly tested during development.

Minor cleanups for the MMC/SD support on avr32:
- Make at32_add_device_mci() properly initialize "missing"
platform data ... so boards like STK1002 won't try GPIO 0.
- Switch over to gpio_is_valid() instead of testing for only
one designated value.
- Provide STK1002 platform data for the unlikely case that
switches are set so first Ethernet controller isn't in use.
(That's the only way to get card detect and writeprotect
switch sensing on the STK1000.)
And get rid of one "unused variable" warning.

net: missing bits of net-namespace / sysctl
Piss-poor sysctl registration API strikes again, film at 11...
What we really need is _pathname_ required to be present in
already registered table, so that kernel could warn about bad
order. That's the next target for sysctl stuff (and generally
saner and more explicit order of initialization of ipv[46]
internals wouldn't hurt either).
For the time being, here are full fixups required by ..._rotable()
stuff; we make per-net sysctl sets descendents of "ro" one and
make sure that sufficient skeleton is there before we start registering
per-net sysctls.

KVM: s390: Fix program check on interrupt delivery handling
The current interrupt handling on s390 misbehaves on an error case. On s390
each cpu has the prefix area (lowcore) for interrupt delivery. This memory
must always be available. If we fail to access the prefix area for a guest
on interrupt delivery the configuration is completely unusable. There is no
point in sending another program interrupt to an inaccessible lowcore.
Furthermore, we should not bug the host kernel, because this can be triggered
by userspace. I think the guest kernel itself can not trigger the problem, as
SET PREFIX and SIGNAL PROCESSOR SET PREFIX both check that the memory is
available and sane. As this is a userspace bug (e.g. setting the wrong guest
offset, unmapping guest memory) we should kill the userspace process instead
of BUGing the host kernel.
In the long term we probably should notify the userspace process about this
problem.

KVM: s390: Fix guest kconfig
Cornelia Huck noticed that a modular virtio without kvm guest support
leads to a build error in the s390 virtio transport:
CONFIG_VIRTIO=m leads to
ERROR: "vmem_add_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined!
ERROR: "max_pfn" [drivers/s390/kvm/kvm_virtio.ko] undefined!
ERROR: "vmem_remove_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined!
The virtio transport only works with kvm guest support and only as a
builtin. Lets change the build process of drivers/s390/kvm/kvm_virtio.c
to depend on kvm guest support, which is also a bool.
CONFIG_S390_GUEST already selects CONFIG_VIRTIO, that should prevent
CONFIG_S390_GUEST=y CONFIG_VIRTIO=n situations.

KVM: Avoid instruction emulation when event delivery is pending
When an event (such as an interrupt) is injected, and the stack is
shadowed (and therefore write protected), the guest will exit. The
current code will see that the stack is shadowed and emulate a few
instructions, each time postponing the injection. Eventually the
injection may succeed, but at that time the guest may be unwilling
to accept the interrupt (for example, the TPR may have changed).
This occurs every once in a while during a Windows 2008 boot.
Fix by unshadowing the fault address if the fault was due to an event
injection.

ALSA: Allow to force model to intel-mac-v3 in snd_hda_intel (sigmatel).
Currently, even if you pass model=intel-mac-v3 as a module parameter to
snd_hda_intel, the function patch_stac922x (patch_sigmatel.c) will still
try to auto-detect the model type. This is a problem on my MacBook Pro 1st
generation, which needs intel-mac-v3, but sometimes incorrectly reports
0x00000100 as subsystem id, which causes the switch in patch_stac922x to
select intel-mac-v4.
To fix this, I added a new model called intel-mac-auto, so in case no
module parameter is passed, and an Intel Mac board is detected, the
model will be automatically detected, while no detection will be done
if the model is forced to intel-mac-v3.
This problem has been around for quite a while, and I used to fix it
by moving the case statement for 0x00000100 in patch_stac922x so that
intel-mac-v3 is chosen.
Another way to fix the problem would be to check if a module parameter
was set directly in patch_stac922x, using something like this:
if (spec->board_config == STAC_INTEL_MAC_V3 &&
!codec->bus->modelname) {
But I think it is less elegant (if you prefer that way, I can prepare a
patch).

Check for orig_start exceeding rlimit taken to sys_fcntl().
Failing expand_files() in dup{2,3}() now gets -EMFILE remapped to -EBADF.

[PATCH] dup3 fix
Al Viro notice one cornercase that the new dup3() code. The dup2()
function, as a special case, handles dup-ing to the same file
descriptor. In this case the current dup3() code does nothing at
all. I.e., it ingnores the flags parameter. This shouldn't happen,
the close-on-exec flag should be set if requested.
In case the O_CLOEXEC bit in the flags parameter is not set the
dup3() function should behave in this respect identical to dup2().
This means dup3(fd, fd, 0) should not actively reset the c-o-e
flag.
The patch below implements this minor change.

in dup2() behaviour]

[patch 4/4] vfs: immutable inode checking cleanup
Move the immutable and append-only checks from chmod, chown and utimes
into notify_change(). Checks for immutable and append-only files are
always performed by the VFS and not by the filesystem (see
permission() and may_...() in namei.c), so these belong in
notify_change(), and not in inode_change_ok().
This should be completely equivalent.

[patch 3/4] fat: dont call notify_change
The FAT_IOCTL_SET_ATTRIBUTES ioctl() calls notify_change() to change
the file mode before changing the inode attributes. Replace with
explicit calls to security_inode_setattr(), fat_setattr() and
fsnotify_change().
This is equivalent to the original. The reason it is needed, is that
later in the series we move the immutable check into notify_change().
That would break the FAT_IOCTL_SET_ATTRIBUTES ioctl, as it needs to
perform the mode change regardless of the immutability of the file.
[Fix error if fat is built as a module. Thanks to OGAWA Hirofumi for
noticing.]

[patch 1/4] vfs: utimes: move owner check into inode_change_ok()
Add a new ia_valid flag: ATTR_TIMES_SET, to handle the
UTIMES_OMIT/UTIMES_NOW and UTIMES_NOW/UTIMES_OMIT cases. In these
cases neither ATTR_MTIME_SET nor ATTR_ATIME_SET is in the flags, yet
the POSIX draft specifies that permission checking is performed the
same way as if one or both of the times was explicitly set to a
timestamp.
See the path "vfs: utimensat(): fix error checking for
{UTIME_NOW,UTIME_OMIT} case" by Michael Kerrisk for the patch
introducing this behavior.
This is a cleanup, as well as allowing filesystems (NFS/fuse/...) to
perform their own permission checking instead of the default.

[PATCH] fix MAY_CHDIR/MAY_ACCESS/LOOKUP_ACCESS mess
* MAY_CHDIR is redundant - it's an equivalent of MAY_ACCESS
* MAY_ACCESS on fuse should affect only the last step of pathname resolution
* fchdir() and chroot() should pass MAY_ACCESS, for the same reason why
chdir() needs that.

removed; it has no business being in nameidata.

[patch 05/14] hpfs: dont call permission()
hpfs_unlink() calls permission() prior to truncating the file. HPFS
doesn't define a .permission method, so replace with explicit call to
generic_permission().
This is equivalent, except that devcgroup_inode_permission() and
security_inode_permission() are not called.
The truncation is just an implementation detail of the unlink, so
these security checks are unnecessary.
I suspect that even calling generic_permission() is unnecessary, since
we shouldn't mind if the file isn't writable. But I leave that to the
maintainer to decide.

[PATCH] sysctl: keep track of tree relationships
In a sense, that's the heart of the series. It's based on the following
property of the trees we are actually asked to add: they can be split into
stem that is already covered by registered trees and crown that is entirely
new. IOW, if a/b and a/c/d are introduced by our tree, then a/c is also
introduced by it.
That allows to associate tree and table entry with each node in the union;
while directory nodes might be covered by many trees, only one will cover
the node by its crown. And that will allow much saner logics for /proc/sys
in the next patches. This patch introduces the data structures needed to
keep track of that.
When adding a sysctl table, we find a "parent" one. Which is to say,
find the deepest node on its stem that already is present in one of the
tables from our table set or its ancestor sets. That table will be our
parent and that node in it - attachment point. Add our table to list
anchored in parent, have it refer the parent and contents of attachment
point. Also remember where its crown lives.

[PATCH] allow delayed freeing of ctl_table_header
Refcount the sucker; instead of freeing it by the end of unregistration
just drop the refcount and free only when it hits zero. Make sure that
we _always_ make ->unregistering non-NULL in start_unregistering().
That allows anybody to get a reference to such puppy, preventing its
freeing and reuse. It does *not* block unregistration. Anybody who
holds such a reference can
* try to grab a "use" reference (ctl_head_grab()); that will
succeeds if and only if it hadn't entered unregistration yet. If it
succeeds, we can use it in all normal ways until we release the "use"
reference (with ctl_head_finish()). Note that this relies on having
->unregistering become non-NULL in all cases when one starts to unregister
the sucker.
* keep pointers to ctl_table entries; they *can* be freed if
the entire thing is unregistered. However, if ctl_head_grab() succeeds,
we know that unregistration had not happened (and will not happen until
ctl_head_finish()) and such pointers can be used safely.
IOW, now we can have inodes under /proc/sys keep references to ctl_table
entries, protecting them with references to ctl_table_header and
grabbing the latter for the duration of operations that require access
to ctl_table. That won't cause deadlocks, since unregistration will not
be stopped by mere keeping a reference to ctl_table_header.

[patch] vfs: fix lookup on deleted directory
Lookup can install a child dentry for a deleted directory. This keeps
the directory dentry alive, and the inode pinned in the cache and on
disk, even after all external references have gone away.
This isn't a big problem normally, since memory pressure or umount
will clear out the directory dentry and its children, releasing the
inode. But for UBIFS this causes problems because its orphan area can
overflow.
Fix this by returning ENOENT for all lookups on a S_DEAD directory
before creating a child dentry.
Thanks to Zoltan Sogor for noticing this while testing UBIFS, and
Artem for the excellent analysis of the problem and testing.

mmc: Add per-card debugfs support
For each card successfully added to the bus, create a subdirectory under
the host's debugfs root with information about the card.
At the moment, only a single file is added to the card directory for
all cards: "state". It reflects the "state" field in struct mmc_card,
indicating whether the card is present, readonly, etc.
For MMC and SD cards (not SDIO), another file is added: "status".
Reading this file will ask the card about its current status and
return it. This can be useful if the card just refuses to respond to
any commands, which might indicate that the card state is not what the
MMC core thinks it is (due to a missing stop command, for example.)

SCSI: fix race in device_create
There is a race from when a device is created with device_create() and
then the drvdata is set with a call to dev_set_drvdata() in which a
sysfs file could be open, yet the drvdata will be NULL, causing all
sorts of bad things to happen.
This patch fixes the problem by using the new function,
device_create_drvdata(). It fixes the problem in all of the scsi
drivers that need it.

The problem is ch_probe stores ch's private data at a wrong place.
We need to store it at scsi_device->sdev_gendev but the above patch
stores it at device struct that device_create_drvdata returns. So we
hit an oops when ch_remove accesses
scsi_device->sdev_gendev->driver_data, which is NULL.
Actually, there wasn't a race because ch doesn't create sysfs files
with device struct that device_create returns. This patch puts back
dev_set_drvdata() to set ch's private data properly.

[SCSI] Command protection operation
Controllers that support DMA of protection information must be told
explicitly how to handle the I/O. The controller has no knowledge of
the protection capabilities of the target device so this information
must be passed in the scsi_cmnd.
- The protection operation tells the HBA whether to generate, strip or
verify protection information.
- The protection type tells the HBA which layout the target is
formatted with. This is necessary because the controller must be
able to correctly interpret the included protection information in
order to verify it.
- When a scsi_cmnd is reused for error handling the protection
operation must be cleared and saved while error handling is in
progress.
- prot_op and prot_type are placed in an existing hole in scsi_cmnd
and don't cause the structure to grow.

[SCSI] Host protection capabilities
Controllers that support protection information must indicate this to
the SCSI midlayer so that the ULD can prepare scsi_cmnds accordingly.
This patch implements a host mask and various types of protection:
- DIF Type 1-3 (between HBA and disk)
- DIX Type 0-3 (between OS and HBA)
The patch also allows the HBA to set the guard type to something
different than the T10-mandated CRC.

[SCSI] fix shared tag map tag allocation
When drivers use a shared tag map we can end up with more requests
than tags, because the tag map is shost->can_queue tags and there
can be sdevs * sdev->queue_depth requests. In scsi_request_fn
if tag allocation fails we just drop down to just dequeueing the
tag without a tag. The problem is that drivers using the shared tag
map rely on a valid tag always being set, because it will use the
tag number to lookup commands later.
This patch has us check if we got a valid tag when the host lock
is held right before we check if the host queue is ready. We do the
check here because to allocate the tag we need the q lock, but
if the tag is bad we want to add the device/q onto the starved list
which requires the host lock.

[SCSI] fix shared tag map setup
Currently qla4xxx and stex pass in their can_queue values into
scsi_activate_tcq because they wanted the tag map that large.
The problem with this is that it ends up also setting the queue
depth to that large value. All we want to do this in this case
is set the device queue depth and the other device settings.
We do not need to touch the tag map sizing because the drivers
had setup that map according to their can_queue limits when the
shared map was created.
The scsi mid layer in request_fn will then handle the case where we
have more requests than available tags when it checks the host
queue ready function.

mm: print swapcache page count in show_swap_cache_info()
Every arch implements its own show_mem() function. Most of them share
quite some code, some of them are completely identical.
This series implements a generic version of this function and migrates
almost all architectures to it.
This patch:
Most show_mem() implementations calculate the amount of pages within
the swapcache every time. Move the output to a more appropriate place
and use the anyway available total_swapcache_pages variable.

/proc/PID/syscall
This adds /proc/PID/syscall and /proc/PID/task/TID/syscall magic files.
These use task_current_syscall() to show the task's current system call
number and argument registers, stack pointer and PC. For a task blocked
but not in a syscall, the file shows "-1" in place of the syscall number,
followed by only the SP and PC. For a task that's not blocked, it shows
"running".

task_current_syscall
This adds the new function task_current_syscall() on machines where the
asm/syscall.h interface is supported (CONFIG_HAVE_ARCH_TRACEHOOK). It's
exported for modules to use in the future. This function safely samples
the state of a blocked thread to collect what system call it is blocked
in, and the six system call argument registers.

tracehook: wait_task_inactive
This extends wait_task_inactive() with a new argument so it can be used in
a "soft" mode where it will check for the task changing state unexpectedly
and back off. There is no change to existing callers. This lays the
groundwork to allow robust, noninvasive tracing that can try to sample a
blocked thread but back off safely if it wakes up.

tracehook: CONFIG_HAVE_ARCH_TRACEHOOK
This adds the generic HAVE_ARCH_TRACEHOOK kconfig item. Each arch should
add to some Kconfig file:
select HAVE_ARCH_TRACEHOOK
if the arch code uses all the latest hooks to enable newfangled tracing
and debugging code. The comment in arch/Kconfig lists all the
prerequisite arch support. When all these are available, setting
HAVE_ARCH_TRACEHOOK will allow enabling any new features that depend on
the modern arch interfaces.

Author: Roland McGrath <roland at redhat.com>
Date: Fri Jul 25 19:45:57 2008 -0700
tracehook: asm/syscall.h
This adds asm-generic/syscall.h, which documents what a real
asm-ARCH/syscall.h file should define. This is not used yet, but will
provide all the machine-dependent details of examining a user system call
about to begin, in progress, or just ended.
Each arch should add an asm-ARCH/syscall.h that defines all the entry
points documented in asm-generic/syscall.h, as short inlines if possible.
This lets us write new tracing code that understands user system call
registers, without any new arch-specific work.

tracehook: TIF_NOTIFY_RESUME
This adds tracehook.h inlines to enable a new arch feature in support of
user debugging/tracing. This is not used yet, but it lays the groundwork
for a debugger to be able to wrangle a task that's possibly running,
without interrupting its syscalls in progress.
Each arch should define TIF_NOTIFY_RESUME, and in their entry.S code treat
it much like TIF_SIGPENDING. That is, it causes you to take the slow path
when returning to user mode, where you get the full user-mode state
accessible as for signal handling or ptrace. The arch code should check
TIF_NOTIFY_RESUME after handling TIF_SIGPENDING. When it's set, clear it
and then call tracehook_notify_resume().
In future, tracing code will call set_notify_resume() when it wants to get
a callback in tracehook_notify_resume().
