Merge tag 'sched_urgent_for_v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull scheduler fixes from Borislav Petkov:

 - Have get_push_task() check whether current has migration disabled and
   thus avoid useless invocations of the migration thread

 - Rework initialization flow so that all rq->core's are initialized,
   even of CPUs which have not been onlined yet, so that iterating over
   them all works as expected

* tag 'sched_urgent_for_v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  sched: Fix get_push_task() vs migrate_disable()
  sched: Fix Core-wide rq->lock for uninitialized CPUs
