* kvm-arm64/nv-tcr2:
  : Fixes to the handling of TCR_EL1, courtesy of Marc Zyngier
  :
  : Series addresses a couple gaps that are present in KVM (from cover
  : letter):
  :
  :   - VM configuration: HCRX_EL2.TCR2En is forced to 1, and we blindly
  :     save/restore stuff.
  :
  :   - trap bit description and routing: none, obviously, since we make a
  :     point in not trapping.
  KVM: arm64: Honor trap routing for TCR2_EL1
  KVM: arm64: Make PIR{,E0}_EL1 save/restore conditional on FEAT_TCRX
  KVM: arm64: Make TCR2_EL1 save/restore dependent on the VM features
  KVM: arm64: Get rid of HCRX_GUEST_FLAGS
  KVM: arm64: Correctly honor the presence of FEAT_TCRX
