Subject[PATCH RFC v2] Fix race window during idle cpu selection.
Date
This patch tries to fix a possible race window that lets multiple
tasks wakeup on the same cpu. schbench, uperf & Jackbench (Android)
mostly showed improvements while none of the other standard benchmarks
have shown any regression.

changes from v1->v2:
1. Added the performance numbers.
2. Did not include the debug patch.
It can still be found at
