[GIT PULL] KVM/arm64 fixes for 6.1, take #3

[Marc Zyngier]

Paolo,

Here's another set of fixes for 6.1. Two of them are critical fixes
(MTE support triggering an invalid pointer dereference in nVHE
configurations, SME trapping not enabled in VHE configurations).
Thankfully, these configuration are pretty rare, because hardly anyone
is making us of MTE yet, and that SME HW simply doesn't exist in the
wild.

The rest is a limited set of fixes for relatively harmless bugs and
documentation update.

Please pull,

	M.

  arm64: booting: Document our requirements for fine grained traps with SME (2022-11-01 19:30:34 +0000)

----------------------------------------------------------------
KVM/arm64 fixes for 6.1, take #3

- Fix the pKVM stage-1 walker erronously using the stage-2 accessor

- Correctly convert vcpu->kvm to a hyp pointer when generating
  an exception in a nVHE+MTE configuration

- Check that KVM_CAP_DIRTY_LOG_* are valid before enabling them

- Fix SMPRI_EL1/TPIDR2_EL0 trapping on VHE

- Document the boot requirements for FGT when entering the kernel
  at EL1
