[GIT PULL] arm64 fixes for 6.18

[Will Deacon]

Hi Linus,

Apologies for sending this during the US holidays but please can you
pull these three straightforward arm64 fixes for 6.18?

We've got a revert due to one of the recent CCA commits breaking ACPI
firmware-based error reporting, a fix for a hard-lockup introduced by a
prior fix affecting non-default (CONFIG_EXPERT) configurations and
another ACPI fix for systems using MMIO-based timers.

Other than that, we're looking pretty good.

Cheers,

Will
