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

Pull x86 fix from Thomas Gleixner:
 "A single fix for a APIC regression introduced in 4.0 which went
  undetected until now.

  I screwed up the x2apic cleanup in a subtle way.  The screwup is only
  visible on systems which have x2apic preenabled in the BIOS and need
  to disable it during boot"
