[GIT PULL] EFI fixes for v6.2 #2

[Ard Biesheuvel <ardb@kernel.org>]

Hello Linus,

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.

Please pull.

----------------------------------------------------------------
Some more EFI fixes for v6.2:

- 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 Matt Garrett's MAINTAINERS entry for efivarfs
