+int hv_enable_direct_tlbflush(struct kvm_vcpu *vcpu)I would've avoided re-using 'hv_enable_direct_tlbflush()' name which we
+{
already have in vmx. In fact, in the spirit of this patch, I'd suggest
we create arch/x86/kvm/vmx/vmx_onhyperv.c and move the existing
hv_enable_direct_tlbflush() there. We can then re-name it to e.g.
vmx_enable_hv_direct_tlbflush()
so the one introduced by this patch will be
svm_enable_hv_direct_tlbflush()
