[PATCH 22/45] KVM: x86: Drop kvm_arch_vcpu_free()

From: Sean Christopherson <hidden>
Date: 2019-10-22 02:02:28
Also in: kvm, kvmarm, linux-mips, lkml
Subsystem: kernel virtual machine for x86 (kvm/x86), the rest, x86 architecture (32-bit and 64-bit) · Maintainers: Sean Christopherson, Paolo Bonzini, Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen

Remove the superfluous kvm_arch_vcpu_free() as it is no longer called
from commmon KVM code.  Note, kvm_arch_vcpu_destroy() *is* called from
common code, i.e. choosing which function to whack is not completely
arbitrary.
