[jstultz] Briefly reviewed Rafael's wakelock patchset, did some initial testing and reported one locking issue (Feb 21): DONE
[jstultz] Working to get a ARM test platform working w/ suspend/resume functioning so I can test Rafael's work w/ Android (Feb 28): DONE

[jstultz] Compare and contrast Rafael's wakelock patches with Android's wakelock patches by testing and looking for differences in behavior: DONE
Work items for 12.04:
[jstultz] Reviewed Arve's recent rework of the wakelock code(April 11): DONE
[jstultz] Generated a patch to remove the userwakelock api's use of the wakelock shim, instead having it use the wakeup_source api directly(April 11): DONE
