* '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
