* 'x86-cleanups-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  x86, nmi: Use predefined numbers instead of hardcoded one
  x86: asm/processor.h: remove double declaration
  x86, mtrr: replace MTRRdefType_MSR with msr-index's MSR_MTRRdefType
  x86, mtrr: replace MTRRfix4K_C0000_MSR with msr-index's MSR_MTRRfix4K_C0000
  x86, mtrr: remove mtrr MSRs double declaration
  x86, mtrr: replace MTRRfix16K_80000_MSR with msr-index's MSR_MTRRfix16K_80000
  x86, mtrr: replace MTRRfix64K_00000_MSR with msr-index's MSR_MTRRfix64K_00000
  x86, mtrr: replace MTRRcap_MSR with msr-index's MSR_MTRRcap
  x86: mce: remove duplicated #include
  x86: msr-index.h remove duplicate MSR C001_0015 declaration
  x86: clean up arch/x86/kernel/tsc_sync.c a bit
  x86: use symbolic name for VM86_SIGNAL when used as vm86 default return
  x86: added 'ifndef _ASM_X86_IOMAP_H' to iomap.h
  x86: avoid multiple declaration of kstack_depth_to_print
  x86: vdso/vma.c declare vdso_enabled and arch_setup_additional_pages before they get used
  x86: clean up declarations and variables
  x86: apic/x2apic_cluster.c x86_cpu_to_logical_apicid should be static
  x86 early quirks: eliminate unused function
