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"
