Another issue to consider for live migration: right now we only kunmap() and
release_page_dirty() the vmcs12 page after a vmclear (or vmxof, etc.). However,
we may need to do this also on exit to user space (KVM_VCPU_RUN ioctl
completes), so that live migration knows this page is dirty and needs to be
copied.
