* kvm-arm64/writable-midr:
  : Writable implementation ID registers, courtesy of Sebastian Ott
  :
  : Introduce a new capability that allows userspace to set the
  : ID registers that identify a CPU implementation: MIDR_EL1, REVIDR_EL1,
  : and AIDR_EL1. Also plug a hole in KVM's trap configuration where
  : SMIDR_EL1 was readable at EL1, despite the fact that KVM does not
  : support SME.
  KVM: arm64: Fix documentation for KVM_CAP_ARM_WRITABLE_IMP_ID_REGS
  KVM: arm64: Copy MIDR_EL1 into hyp VM when it is writable
  KVM: arm64: Copy guest CTR_EL0 into hyp VM
  KVM: selftests: arm64: Test writes to MIDR,REVIDR,AIDR
  KVM: arm64: Allow userspace to change the implementation ID registers
  KVM: arm64: Load VPIDR_EL2 with the VM's MIDR_EL1 value
  KVM: arm64: Maintain per-VM copy of implementation ID regs
  KVM: arm64: Set HCR_EL2.TID1 unconditionally
