Subject: [PATCH 0/4] Android Alarm Driver Cleanups (for staging-next/3.5)

This patch-set moves the Android alarm driver in staging to use
the upstreamed CLOCK_BOOTTIME and alarmtimer interfaces, allowing
us to greatly shrink the alarm driver.

The Google Android team has been using these patches in its AOSP tree
for a little while without any reported issues.

The only gotcha is that I needed to make one alarmtimer interface
non-static in order to support the android alarm driver. This sort
of is a grey area for the staging tree, but I'm the author of the
upstreamed alarmtimer code, and Thomas (cc'ed) had no objection
to this patch going in via the staging tree, instead of -tip so 
this should be ok (and much simpler then dealing with
cross-maintainer dependencies).

Greg: Would you mind applying this set to staging-next for 3.5?

thanks
-john
