Linus Torvalds 4bbbf13fd5 Very good bug-fixes:
- In the low-level assembler code we would jump to check events
    even if none were present. This incorrect behavior had been there
    since 2.6.27 days!
  - When using the fast-path for ACK-ing interrupts we were using the
    Linux IRQ numbers instead of the Xen ones (and they can differ) and
    missing interrupts in process.
  - Fix bootup crashes when ACPI hotplug CPUs were present and they
    would expand past the set number of CPUs we were allocated.
  - Deal with broken BIOSes when uploading C-states to the hypervisor.
  - Disable the cpuid check for MWAIT_LEAF if the ACPI PAD driver is
    loaded. If the ACPI PAD driver is used it will crash, so lets not
    export the functionality so the ACPI PAD driver won't load.

Pull Xen fixes from Konrad Rzeszutek Wilk:
 "Some of these had been in existence since the 2.6.27 days, some since
  3.0 - and some due to new features added in v3.4.

  The one that is most interesting is David's one - in the low-level
  assembler code we had be checking events needlessly.  With his patch
  now we do it when the appropriate flag is set - with the added benefit
  that we can process events faster.  Stefano's is fixing a mistake
  where the Linux IRQ numbers were ACK-ed instead of the Xen IRQ,
  resulting in missing interrupts.  The other ones are bootup related
  that can show up on various hardware."
