[PATCH v2 12/43] KVM: x86: Tweak halt emulation helper names to free up kvm_vcpu_halt()

[Sean Christopherson]

Rename a variety of HLT-related helpers to free up the function name
"kvm_vcpu_halt" for future use in generic KVM code, e.g. to differentiate
between "block" and "halt".

No functional change intended.
