Pull x86 APIC fixup from Dave Hansen:
 "Revert VERW fixed addressing patch.

  The reverted commit is not x86/apic material and was cruft left over
  from a merge.

  I believe the sequence of events went something like this:

   - The commit in question was added to x86/urgent

   - x86/urgent was merged into x86/apic to resolve a conflict

   - The commit was zapped from x86/urgent, but *not* from x86/apic

   - x86/apic got pullled (yesterday)

  I think we need to be a bit more vigilant when zapping things to make
  sure none of the other branches are depending on the zapped material"
