Merge branch 'efi-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull EFI fixes from Ingo Molnar:
 "Three fixes to EFI mixed boot mode, mostly related to x86-64 vmap
  stacks activated years ago, bug-fixed recently for EFI, which had
  knock-on effects of various 1:1 mapping assumptions in mixed mode.

  There's also a READ_ONCE() fix for reading an mmap-ed EFI firmware
  data field only once, out of caution"
