Pull x86 apic changes from Ingo Molnar:
 "The main changes in this cycle were:

   - Re-activate the hw IRQ resend mechanism that was downgraded to a
     sw-resend unintentionally. (Ruslan Ruslichenko)

   - Avoid sporadic spurious hrtimer interrupts (Frederic Weisbecker)"

[ Let's see if the io_apic retrigger ends up surviving this release, it
  got reverted last time because it found problems elsewhere  - Linus ]
