[RFC 0/3] sched: fix nr_busy_cpus

[Vincent Guittot]

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
