Merge branch 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Peter Anvin: "This series fixes a couple of build failures, and fixes MTRR cleanup and memory setup on very specific memory maps. Finally, it fixes triggering backtraces on all CPUs, which was inadvertently disabled on x86." * 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/efi: Fix dummy variable buffer allocation x86: Fix trigger_all_cpu_backtrace() implementation x86: Fix section mismatch on load_ucode_ap x86: fix build error and kconfig for ia32_emulation and binfmt range: Do not add new blank slot with add_range_with_merge x86, mtrr: Fix original mtrr range get for mtrr_cleanup
