Merge branch kvm-arm64/wfxt into kvmarm-master/next
* kvm-arm64/wfxt:
: .
: Add support for the WFET/WFIT instructions that provide the same
: service as WFE/WFI, only with a timeout.
: .
KVM: arm64: Expose the WFXT feature to guests
KVM: arm64: Offer early resume for non-blocking WFxT instructions
KVM: arm64: Handle blocking WFIT instruction
KVM: arm64: Introduce kvm_counter_compute_delta() helper
KVM: arm64: Simplify kvm_cpu_has_pending_timer()
arm64: Use WFxT for __delay() when possible
arm64: Add wfet()/wfit() helpers
arm64: Add HWCAP advertising FEAT_WFXT
arm64: Add RV and RN fields for ESR_ELx_WFx_ISS
