Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Peter Anvin: "This is a collection of miscellaneous fixes, the most important one is the fix for the Samsung laptop bricking issue (auto-blacklisting the samsung-laptop driver); the efi_enabled() changes you see below are prerequisites for that fix. The other issues fixed are booting on OLPC XO-1.5, an UV fix, NMI debugging, and requiring CAP_SYS_RAWIO for MSR references, just as with I/O port references." * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: samsung-laptop: Disable on EFI hardware efi: Make 'efi_enabled' a function to query EFI facilities smp: Fix SMP function call empty cpu mask race x86/msr: Add capabilities check x86/dma-debug: Bump PREALLOC_DMA_DEBUG_ENTRIES x86/olpc: Fix olpc-xo1-sci.c build errors arch/x86/platform/uv: Fix incorrect tlb flush all issue x86-64: Fix unwind annotations in recent NMI changes x86-32: Start out cr0 clean, disable paging before modifying cr3/4
