<div class='commit-subject'>Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip</div><div class='commit-msg'>Pull x86 bugfix from Thomas Gleixner:
 "A single bugfix for the recent changes related to registering the boot
  cpu when this has not happened before prefill_possible_map().

  The main problem with this change got fixed already, but we missed the
  case where the local APIC is not yet mapped, when prefill_possible_map()
  is invoked, so the registration of the boot cpu which has the APIC bit
  set in CPUID will explode.

  I should have seen that issue earlier, but all I can do now is feeling
  embarassed"
