[PATCH 0/4] irq_work: Fix ordering issue

[Frederic Weisbecker]

Patches 1 and 2 are the fix part, 3 is a cleanup, 4 is
extra-optimization (rfc).

Thanks to Paul that confirmed my doubts about ordering on cmpxchg() failure.

Frederic Weisbecker (4):
  irq_work: Convert flags to atomic_t
  irq_work: Fix irq_work_claim() ordering
  irq_work: Slightly simplify IRQ_WORK_PENDING clearing
  irq_work: Weaken ordering in irq_work_run_list()
