Sebastian Andrzej Siewior 386ef214c3 sched: Teach the forced-newidle balancer about CPU affinity limitation. ... try_steal_cookie() looks at task_struct::cpus_mask to decide if the task could be moved to `this' CPU. It ignores that the task might be in a migration disabled section while not on the CPU. In this case the task must not be moved otherwise per-CPU assumption are broken. Use is_cpu_allowed(), as suggested by Peter Zijlstra, to decide if the a task can be moved.
