Pull EFI fix from Thomas Gleixner:
 "A single fix for a EFI boot regression on X86 which was caused by the
  recent rework of the EFI memory map parsing. On systems with invalid
  memmap entries the cleanup function uses an value which cannot be
  relied on in this stage. Use the actual EFI memmap entry instead"
