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

[Ard Biesheuvel]

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.



The following changes since commit d3f450533bbcb6dd4d7d59cadc9b61b7321e4ac1:

  efi: tpm: Avoid READ_ONCE() for accessing the event log (2023-01-13 17:15:17 +0100)

  efi: Remove Matthew Garrett as efivarfs maintainer (2023-01-18 09:24:48 +0100)

----------------------------------------------------------------
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

I was all "who?", and had to look, and then went "Oh, you mean _Matthew_".

I didn't think he's ever gone by Matt, at least in kernel circles -
either in email or in person. At least not that I can remember.

So I edited it. Apologies to Matthew if he has now started going by Matt.
