  x86/efi: Check status field to validate BGRT header (2014-02-14 10:07:15 +0000)

----------------------------------------------------------------
 * Fix boot failure on 32-bit EFI due to the recent EFI memmap changes
   merged during the merge window - Borislav Petkov

 * Avoid a crash during efi_bgrt_init() by detecting invalid BGRT
   headers based on the 'status' field.
