Since we don't do energy-aware wakeups when we are overutilized, always honoring sync wakeups in this state does not prevent wake-wide mechanics overruling the flag as normal. This patch is based upon previous work to build EAS for android products. sync-hint code taken from commit 4a5e890ec60d "sched/fair: add tunable to force selection at cpu granularity" written by Juri Lelli <juri.lelli@arm.com> Signed-off-by: Chris Redpath <chris.redpath@arm.com> (cherry-picked from commit f1ec666a62dec1083ed52fe1ddef093b84373aaf) [ Moved the feature to find_energy_efficient_cpu() ] Signed-off-by: Quentin Perret <quentin.perret@arm.com> Change-Id: I4b3d79141fc8e53dc51cd63ac11096c2e3cb10f5
