Pull EFI fixes from Ard Biesheuvel:
 "Another couple of EFI fixes, of which the first two were already in
  -next when I sent out the previous PR, but they caused some issues on
  non-EFI boots so I let them simmer for a bit longer.

   - ensure the EFI ResetSystem and ACPI PRM calls are recognized as
     users of the EFI runtime, and therefore protected against
     exceptions

   - account for the EFI runtime stack in the stacktrace code

   - remove Matthew Garrett's MAINTAINERS entry for efivarfs"
