Peter Zijlstra bbc8cb5bae sched: Reduce update_group_power() calls ... Currently we update cpu_power() too often, update_group_power() only updates the local group's cpu_power but it gets called for all groups. Furthermore, CPU_NEWLY_IDLE invocations will result in all cpus calling it, even though a slow update of cpu_power is sufficient. Therefore move the update under 'idle != CPU_NEWLY_IDLE && local_group' to reduce superfluous invocations.
