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

Pull x86 cleanups from Ingo Molnar:
 "A handful of small cleanups"

* 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/irq: Remove a redundant #ifdef directive
  x86/smp: Remove the redundant #ifdef CONFIG_SMP directive
  x86/smp: Reduce code duplication
  x86/pci-calgary: Use setup_timer() instead of open coding it.
