[PATCH] i386/x86-64: Fix ACPI disabled LAPIC handling mismerge
The patch I submitted earlier to fix disabled LAPIC handling in ACPI was mismerged for some reason I still don't quite understand. Parts of it was applied to the wrong function. This patch fixes it up. Cc: len.brown@intel.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
