Merge tag 'kvmarm-fixes-6.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
* 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
