* kvm-arm64/hvhe:
  : Support for running split-hypervisor w/VHE, courtesy of Marc Zyngier
  :
  : From the cover letter:
  :
  : KVM (on ARMv8.0) and pKVM (on all revisions of the architecture) use
  : the split hypervisor model that makes the EL2 code more or less
  : standalone. In the later case, we totally ignore the VHE mode and
  : stick with the good old v8.0 EL2 setup.
  :
  : We introduce a new "mode" for KVM called hVHE, in reference to the
  : nVHE mode, and indicating that only the hypervisor is using VHE.
  KVM: arm64: Fix hVHE init on CPUs where HCR_EL2.E2H is not RES1
  arm64: Allow arm64_sw.hvhe on command line
  KVM: arm64: Force HCR_E2H in guest context when ARM64_KVM_HVHE is set
  KVM: arm64: Program the timer traps with VHE layout in hVHE mode
  KVM: arm64: Rework CPTR_EL2 programming for HVHE configuration
  KVM: arm64: Adjust EL2 stage-1 leaf AP bits when ARM64_KVM_HVHE is set
  KVM: arm64: Disable TTBR1_EL2 when using ARM64_KVM_HVHE
  KVM: arm64: Force HCR_EL2.E2H when ARM64_KVM_HVHE is set
  KVM: arm64: Key use of VHE instructions in nVHE code off ARM64_KVM_HVHE
  KVM: arm64: Remove alternatives from sysreg accessors in VHE hypervisor context
  arm64: Use CPACR_EL1 format to set CPTR_EL2 when E2H is set
  arm64: Allow EL1 physical timer access when running VHE
  arm64: Don't enable VHE for the kernel if OVERRIDE_HVHE is set
  arm64: Add KVM_HVHE capability and has_hvhe() predicate
  arm64: Turn kaslr_feature_override into a generic SW feature override
  arm64: Prevent the use of is_kernel_in_hyp_mode() in hypervisor code
  KVM: arm64: Drop is_kernel_in_hyp_mode() from __invalidate_icache_guest_page()
