Subject: [PATCH 00/12] Posix Alarm Timers full patchset

The first 8 of these patches are already in -tip for inclusion
in 2.6.38, but I wanted to send them all out again so folks could
try them out and I could hopefully get some feedback on the remaining 
patches in this set.

Specifically, I'm really hoping to get some feedback from any Android
folks on the introduction of CLOCK_BOOTTIME (generic posix version of
ANDROID_ALARM_ELAPSED_REALTIME) which provides CLOCK_MONOTONIC + suspend
time, as well as the posix alarm timers (CLOCK_REALTIME_ALARM and
CLOCK_BOOTTIME_ALARM), which try to provide equivalent functionality
as the Android Alarm Timers.

There are still a few remaining TODOs here, but getting some feedback
as to any limitations this interface has compared to the Android
/dev/alarm interface would be great.

The full set applies ontop of v2.6.37.

thanks
-john
