Merge branch 'kvm-arm64/nv-vgic' into kvmarm/next
* kvm-arm64/nv-vgic:
: NV VGICv3 support, courtesy of Marc Zyngier
:
: Support for emulating the GIC hypervisor controls and managing shadow
: VGICv3 state for the L1 hypervisor. As part of it, bring in support for
: taking IRQs to the L1 and UAPI to manage the VGIC maintenance interrupt.
KVM: arm64: nv: Fail KVM init if asking for NV without GICv3
KVM: arm64: nv: Allow userland to set VGIC maintenance IRQ
KVM: arm64: nv: Fold GICv3 host trapping requirements into guest setup
KVM: arm64: nv: Propagate used_lrs between L1 and L0 contexts
KVM: arm64: nv: Request vPE doorbell upon nested ERET to L2
KVM: arm64: nv: Respect virtual HCR_EL2.TWx setting
KVM: arm64: nv: Add Maintenance Interrupt emulation
KVM: arm64: nv: Handle L2->L1 transition on interrupt injection
KVM: arm64: nv: Nested GICv3 emulation
KVM: arm64: nv: Sanitise ICH_HCR_EL2 accesses
KVM: arm64: nv: Plumb handling of GICv3 EL2 accesses
KVM: arm64: nv: Add ICH_*_EL2 registers to vpcu_sysreg
KVM: arm64: nv: Load timer before the GIC
arm64: sysreg: Add layout for ICH_MISR_EL2
arm64: sysreg: Add layout for ICH_VTR_EL2
arm64: sysreg: Add layout for ICH_HCR_EL2
