FEAT_PAN has been around since ARMv8.1 (over 11 years ago), has no compiler
dependency (we have our own accessors), and is a great security benefit.

Drop CONFIG_ARM64_PAN, and make the support unconditionnal.

Since you mentioned that you were planning to merge this patch, I'd
like to point out that a related change[1] is on its way to Linus via
the KVM tree for 6.19. It is also in -next due to dependencies.

Could you please place these patches on a branch that I can pull in
the kvmarm tree to resolve the conflict? It really amounts to
reverting this patch now that we are guaranteed to have PAN on an
PAN- machine.

You can use for-next/cpufeature. It has these plus the LS64 stuff that
you might also want to pull into the kvm/arm tree.

Please yell if you have any issues.

Cheers,

Will
