Merge branch 'kvm-arm64/vtr-patch' into next

* kvm-arm64/vtr-patch:
  : Inline patching of ICH_VTR_EL2 constant, courtesy of Marc Zyngier
  :
  : Unify readers of ICH_VTR_EL2 on an instruction-patched constant value,
  : avoiding system register accesses known to trap under nested
  : virtualization and sharing the implementation between pKVM and 'regular'
  : KVM.
  KVM: arm64: vgic-v3: Kill kvm_vgic_global_state.ich_vtr_el2
  KVM: arm64: vgic-v3: Simplify initial GICv3 configuration sampling
  KVM: arm64: Convert most ICH_VTR_EL2 accesses to inlined literal value
  KVM: arm64: Add a helper providing an inlined literal value for ICH_VTR_EL2
  KVM: arm64: Move GICv3 broken SEIS implementation detection to a CPU errrata
  KVM: arm64: vgic-v3: Make vtr_to_* helpers use architectural field symbols
