Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Peter Anvin: "Quite a varied little collection of fixes. Most of them are relatively small or isolated; the biggest one is Mel Gorman's fixes for TLB range flushing. A couple of AMD-related fixes (including not crashing when given an invalid microcode image) and fix a crash when compiled with gcov" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, microcode, AMD: Unify valid container checks x86, hweight: Fix BUG when booting with CONFIG_GCOV_PROFILE_ALL=y x86/efi: Allow mapping BGRT on x86-32 x86: Fix the initialization of physnode_map x86, cpu hotplug: Fix stack frame warning in check_irq_vectors_for_cpu_disable() x86/intel/mid: Fix X86_INTEL_MID dependencies arch/x86/mm/srat: Skip NUMA_NO_NODE while parsing SLIT mm, x86: Revisit tlb_flushall_shift tuning for page flushes except on IvyBridge x86: mm: change tlb_flushall_shift for IvyBridge x86/mm: Eliminate redundant page table walk during TLB range flushing x86/mm: Clean up inconsistencies when flushing TLB ranges mm, x86: Account for TLB flushes only when debugging x86/AMD/NB: Fix amd_set_subcaches() parameter type x86/quirks: Add workaround for AMD F16h Erratum792 x86, doc, kconfig: Fix dud URL for Microcode data
