[GIT PULL] KVM/arm64 fixes for 6.12, take #1

[Marc Zyngier <maz@kernel.org>]

Paolo,

Here's the first set of fixes for 6.12. We have fixes for a couple of
pretty theoretical pKVM issues, plus a slightly more annoying fix for
the feature detection infrastructure (details in the tag below). I
expect to have a few more fixes in the coming weeks. Oh, and Joey is
now an official reviewer, replacing James

Please pull,

	M.

  KVM: arm64: Fix kvm_has_feat*() handling of negative features (2024-10-03 19:35:27 +0100)

----------------------------------------------------------------
KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
  system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
  common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
  code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
  down -- hopefully only temporarly
