Merge branch kvm-arm64/pkvm-psci into kvmarm-master/next
* kvm-arm64/pkvm-psci:
: .
: Cleanup of the pKVM PSCI relay CPU entry code, making it slightly
: easier to follow, should someone have to wade into these waters
: ever again.
: .
KVM: arm64: Remove extra ISBs when using msr_hcr_el2
KVM: arm64: pkvm: Use direct function pointers for cpu_{on,resume}
KVM: arm64: pkvm: Turn __kvm_hyp_init_cpu into an inner label
KVM: arm64: pkvm: Simplify BTI handling on CPU boot
KVM: arm64: pkvm: Move error handling to the end of kvm_hyp_cpu_entry
