Do you use paravirt_alloc_pd_clone()? I seem to you remember you
mentioning that it doesn't help you very much. I'm in the process of
unifying pgalloc*, and it seems to me that it would be a bit cleaner
without needing to worry about paravirt_alloc_pd_clone()...

Yes, we do, and it is one of our largest performance gains. It is
clone_pgd_range() that turned out not to be useful.
