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

Pull EFI fixes from Matt Fleming:

 * Prevent accidental deletion of EFI variables through efivarfs that
   may brick machines. We use a whitelist of known-safe variables to
   allow things like installing distributions to work out of the box, and
   instead restrict vendor-specific variable deletion by making
   non-whitelist variables immutable (Peter Jones)
