Merge tag 'efi-urgent' of git:// into x86/urgent

Pull EFI fixes from Matt Fleming:

 * Fix an EFI boot issue preventing a Parallels virtual machine from
   booting because the upper 32-bits of the EFI memmap pointer were
   being discarded in setup_e820(). (Dmitry Skorodumov)

 * Validate that the "efi" kernel parameter gets used with an argument,
   otherwise we will oops. (Ricardo Neri)
