Merge branch kvm-arm64/stage2-vhe-load into kvmarm/next
* kvm-arm64/stage2-vhe-load:
: Setup stage-2 MMU from vcpu_load() for VHE
:
: Unlike nVHE, there is no need to switch the stage-2 MMU around on guest
: entry/exit in VHE mode as the host is running at EL2. Despite this KVM
: reloads the stage-2 on every guest entry, which is needless.
:
: This series moves the setup of the stage-2 MMU context to vcpu_load()
: when running in VHE mode. This is likely to be a win across the board,
: but also allows us to remove an ISB on the guest entry path for systems
: with one of the speculative AT errata.
KVM: arm64: Move VTCR_EL2 into struct s2_mmu
KVM: arm64: Load the stage-2 MMU context in kvm_vcpu_load_vhe()
KVM: arm64: Rename helpers for VHE vCPU load/put
KVM: arm64: Reload stage-2 for VMID change on VHE
KVM: arm64: Restore the stage-2 context in VHE's __tlb_switch_to_host()
KVM: arm64: Don't zero VTTBR in __tlb_switch_to_host()
