Pull EFI fixes from Thomas Gleixner:
 "Two fixes for EFI/PAT:

   - a 32bit overflow bug in the PAT code which was unearthed by the
     large EFI mappings

   - prevent a boot hang on large systems when EFI mixed mode is enabled
     but not used"

  x86/efi: Only map RAM into EFI page tables if in mixed-mode
  x86/mm/pat: Prevent hang during boot when mapping pages
