[GIT PULL] Alarmtimer fixes for 3.1

[john stultz]

Hey Thomas, Ingo, Andrew,

	Again, these were sent out earlier but still haven't been pulled. I'm
leaving for vacation for the next two weeks (although I will
occasionally check email), so I wanted to resend this so it didn't get
missed.

In reviewing the alarmtimer code, I ran across a few bugs that should be
fixed for 3.1 and backported to 3.0-stable.

These are also available in the git repository at:
  git://git.linaro.org/people/jstultz/linux.git fortglx/3.1/tip/timers/alarmtimers

The last of these is a pretty terrible hack, but I've got a more
invasive fix (along with other cleanups) queued on top of these for 3.2
that should resolve it. Feel free to take a peek at those changes here:
  git://git.linaro.org/people/jstultz/linux.git fortglx/3.2/tip/timers/alarmtimers

Let me know if you have any thoughts or feedback!

thanks
-john
