[PATCH Resend 0/3] sched: fix nr_busy_cpus

From: Vincent Guittot
Date: Mon Dec 03 2012 - 07:32:58 EST

The nr_busy_cpus field of the sched_group_power is sometime different from 0
whereas the platform is fully idle. This serie fixes 3 use cases:
- when the SCHED softirq is raised on an idle core for idle load balance but
the platform doesn't go out of the cpuidle state
- when some CPUs enter idle state while booting all CPUs
- when a CPU is unplug and/or replug

Vincent Guittot (3):
sched: fix nr_busy_cpus with coupled cpuidle
sched: fix init NOHZ_IDLE flag
sched: fix update NOHZ_IDLE flag
