Android Kernel Upstreaming for 11.11 (overview)

Registered by John Stultz on 2011-04-29

Covers Android Upstreaming for the 11.11 cycle of both larger works such as completing the Alarm Timers upstreaming as well as starting the Low Memory Killer (or other larger functionality blocks). Also includes smaller efforts like the trivial tree patches, and involvement in Android community discussions on things like wakelocks.
