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.
