Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/urgent
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)
