Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 APIC updates from Ingo Molnar:
 "Continued fallout of the conversion of the x86 IRQ code to the
  hierarchical irqdomain framework: more cleanups, simplifications,
  memory allocation behavior enhancements, mainly in the interrupt
  remapping and APIC code"
