Somehow we need to merge the oe config changes into the one we publish
in git. The intention of the toplevel defconfig-gta01 and
defconfig-gta02 files is that they are our packaging config. It'd be
good if instead of forking it we had a single accurate config for GTA01
and GTA02 in the kernel tree.
I wrote a patch to change these configs on 2.6.24 stable branch, but I
can't test it right now and I wonder about one thing with profiling, on
2.6.27 I enabled FTRACE and it attached stuff to __attribute__ ((naked))
functions and killed FIQ thereby. Can you confirm it OK with whatever
it is OPROFILE does for instrumenting functions? If so I'll add it in
the kernel tree.
