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

Pull irq cleanups from Ingo Molnar:
 "This is a multi-arch cleanup series from Thomas Gleixner, which we
  kept to near the end of the merge window, to not interfere with
  architecture updates.

  This series (motivated by the -rt kernel) unifies more aspects of IRQ
  handling and generalizes PREEMPT_ACTIVE"

* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  preempt: Make PREEMPT_ACTIVE generic
  sparc: Use preempt_schedule_irq
  ia64: Use preempt_schedule_irq
  m32r: Use preempt_schedule_irq
