Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming...

Pull EFI fixes from Matt Fleming:

" - Leave a valid 64-bit IDT installed during runtime EFI mixed mode
    calls to avoid triple faults if an NMI/MCE is received.

  - Revert Ard's change to the libstub get_memory_map() that went into
    the v3.20 merge window because it causes boot regressions on Qemu and
    Xen. "
