Hello Linus,
Please pull the EFI fixes below.
The arm64 exception recovery is not a real fix, but it will be useful to have
in v6.1 going forward, so I've incorporated it here. I hope that's alright.
The following changes since commit 37926f96302d8b6c2bc97990d33e316a3ed6d67f:
efi: runtime: Don't assume virtual mappings are missing if VA == PA == 0 (2022-10-21 11:09:41 +0200)

arm64: efi: Recover from synchronous exceptions occurring in firmware (2022-11-03 18:01:15 +0100)
----------------------------------------------------------------
Second batch of EFI fixes for v6.1
- A pair of tweaks to the EFI random seed code so that externally
provided version of this config table are handled more robustly
- Another fix for the v6.0 EFI variable refactor that turned out to
break Apple machines which don't provide QueryVariableInfo()
- Add some guard rails to the EFI runtime service call wrapper so we can
recover from synchronous exceptions caused by firmware
----------------------------------------------------------------
Ard Biesheuvel (4):
efi: random: reduce seed size to 32 bytes
efi: random: Use 'ACPI reclaim' memory for random seed
efi: efivars: Fix variable writes with unsupported query_variable_store()
