Pull kvm fixes from Paolo Bonzini:
"ARM:

   - 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

  x86:

   - Use SRCU to protect zap in __kvm_set_or_clear_apicv_inhibit()

   - Make argument order consistent for kvcalloc()

   - Userspace API fixes for DEBUGCTL and LBRs"
