Pull sched_ext fixes from Tejun Heo:
 "Five fixes addressing PREEMPT_RT compatibility and locking issues.

  Three commits fix potential deadlocks and sleeps in atomic contexts on
  RT kernels by converting locks to raw spinlocks and ensuring IRQ work
  runs in hard-irq context. The remaining two fix unsafe locking in the
  debug dump path and a variable dereference typo"
