Comment(by werner):
Here's a patch for measuring the time during which interrupts are
globally disabled:
http://svn.openmoko.org/developers/werner/wlan-spi/patches-tracking/find-
irq-blockers.patch
Another source of interrupt latency can be the time during which a
specific interrupt is disabled. The execution time of an interrupt
also (indirectly) shows up in this, but it's better to measure it
directly.
