How about

  kvm_release_pfn_page_clean(pfnpg);

I'm not sure. I always found kvm_release_pfn_clean() ugly, because it
doesn't mark the page 'clean'. I find put_page() more correct.

Something like 'kvm_put_pfn_page()' would make more sense, but I'm so
bad at naming things that I could just as well call it 'bob()'.
