Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull irq updates from Ingo Molnar:
 "Most of the IRQ subsystem changes in this cycle were irq-chip driver
  updates:

   - Qualcomm PDC wakeup interrupt support

   - Layerscape external IRQ support

   - Broadcom bcm7038 PM and wakeup support

   - Ingenic driver cleanup and modernization

   - GICv3 ITS preparation for GICv4.1 updates

   - GICv4 fixes

  There's also the series from Frederic Weisbecker that fixes memory
  ordering bugs for the irq-work logic, whose primary fix is to turn
  work->irq_work.flags into an atomic variable and then convert the
  complex (and buggy) atomic_cmpxchg() loop in irq_work_claim() into a
  much simpler atomic_fetch_or() call.

  There are also various smaller cleanups"
