Keisuke Nishimura 6f312ace4c sched/fair: Take the scheduling domain into account in select_idle_core() ... [ Upstream commit 23d04d8c6b ] When picking a CPU on task wakeup, select_idle_core() has to take into account the scheduling domain where the function looks for the CPU. This is because the "isolcpus" kernel command line option can remove CPUs from the domain to isolate them from other SMT siblings. This change replaces the set of CPUs allowed to run the task from p->cpus_ptr by the intersection of p->cpus_ptr and sched_domain_span(sd) which is stored in the 'cpus' argument provided by select_idle_cpu().
