The kvm_hv_verify_vp_assist() is used in svm object where 
kvm_hv_assist_page_enabled() is called,
so the deletion of this line now brings a link failure. The first version of the 
patch set did not catch
such a simple error, and I assume another discussion thread's in-flight changes 
were merged into.

We may add this line back to easily fix this merge conflict.
