Re: [RFC 0/3] sched: fix nr_busy_cpus

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

Applied to a independent branch in big LITTLE MP tree: fix-nr-busy-cpus-v1 Isn't merged with any other branch.
