Yikes!  It's not intention as of this patch.  It _is_ intentional for the "morph"
patch, as KVM can simply force "has_payload" in kvm_inject_page_fault() when
directly queueing the VM-Exit.  I suspect I botched this patch when splitting the
original changes into separate patches.

Argh, sorry about the versioning mixup.  I distinctly remember thinking this
couldn't possibly have been only the second version...  Should have double-checked
instead of trusting my archive.
