Merge branch 'core-headers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull header cleanup from Ingo Molnar:
 "This is a treewide cleanup, mostly (but not exclusively) with x86
  impact, which breaks implicit dependencies on the asm/realtime.h
  header and finally removes it from asm/acpi.h"
