[PATCH 007/114] x86: rename 'genapic' to 'apic'

From: Ingo Molnar
Date: Wed Jan 28 2009 - 18:48:19 EST

Rename genapic-> to apic-> references because in a future chagne we'll
open-code all the indirect calls (instead of obscuring them via macros),
so we want this reference to be as short as possible.
