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

Pull irq updates from Thomas Gleixner:
 "The irq departement delivers:

   - plug a potential race related to chained interrupt handlers

   - core updates which address the needs of the x86 irqdomain conversion

   - new irqchip callback to support affinity settings for VCPUs

   - the usual pile of updates to interrupt chip drivers

   - a few helper functions to allow further cleanups and
     simplifications

  I have a largish pile of coccinelle scripted/verified cleanups and
  simplifications pending on top of that, but I prefer to send that
  towards the end of the merge window when the arch/driver changes have
  hit your tree to avoid API change wreckage as far as possible"
