[PATCH v3 0/2] sched: fix nr_busy_cpus

From: Vincent Guittot
Date: Fri Feb 08 2013 - 13:06:14 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 some CPUs enter idle state while booting all CPUs
- when a CPU is unplug and/or replug

Change since V2:
- change the initialization to idle state instead of busy state so a CPU that
enters idle during the build of the sched_domain will not corrupt the
initialization state

Change since V1:
- remove the patch for SCHED softirq on an idle core use case as it was
a side effect of the other use cases.

Vincent Guittot (2):
sched: fix init NOHZ_IDLE flag
sched: fix update NOHZ_IDLE flag
