[GIT PULL] EFI fixes for v6.1 (#3)

[Ard Biesheuvel <ardb@kernel.org>]

Hello Linus,

Here's the PR with the patch that gets rid of the misalignment WARN().

The other patch adds an SMBIOS based quirk for Ampere Altra machines. This is
the first time we've added such a quirk on arm64, but fortunately, we can just
call a EFI protocol to grab the type #1 SMBIOS record when running in the stub,
so we don't need all the machinery we have in the kernel proper to parse SMBIOS
data.

Please pull.

  arm64: efi: Fix handling of misaligned runtime regions and drop warning (2022-11-10 23:14:15 +0100)

----------------------------------------------------------------
Third batch of EFI fixes for v6.1

- Force the use of SetVirtualAddressMap() on Ampera Altra arm64
  machines, which crash in SetTime() if no virtual remapping is used
- Drop a spurious warning on misaligned runtime regions when using 16k
  or 64k pages on arm64
