[PATCH 13/22] KVM: VMX: Rename VMX functions to conform to kvm_x86_ops names

From: Sean Christopherson
Date: Thu Jan 27 2022 - 19:54:13 EST


Massage VMX's implementation names for kvm_x86_ops to maximize use of
kvm-x86-ops.h. Leave cpu_has_vmx_wbinvd_exit() as-is to preserve the
cpu_has_vmx_*() pattern used for querying VMCS capabilities. Keep
pi_has_pending_interrupt() as vmx_dy_apicv_has_pending_interrupt() does
a poor job of describing exactly what is being checked in VMX land.

No functional change intended.
