Merge branch kvm-arm64/nv-trap-fixes into kvmarm/next
* kvm-arm64/nv-trap-fixes:
: NV trap forwarding fixes, courtesy Miguel Luis and Marc Zyngier
:
: - Explicitly define the effects of HCR_EL2.NV on EL2 sysregs in the
: NV trap encoding
:
: - Make EL2 registers that access AArch32 guest state UNDEF or RAZ/WI
: where appropriate for NV guests
KVM: arm64: Handle AArch32 SPSR_{irq,abt,und,fiq} as RAZ/WI
KVM: arm64: Do not let a L1 hypervisor access the *32_EL2 sysregs
KVM: arm64: Refine _EL2 system register list that require trap reinjection
arm64: Add missing _EL2 encodings
arm64: Add missing _EL12 encodings
