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
