Merge branch 'for-ingo' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-sfi-2.6 into x86/apic
Merge reason: the SFI (Simple Firmware Interface) feature in the ACPI tree needs this cleanup, pull it into the APIC branch as well so that there's no interactions. Signed-off-by: Ingo Molnar <mingo@elte.hu>
