So I have a pure (and even stupid) question to ask before the rest of
details.. it's pure question because I know little on guest_memfd,
especially on the future plans.

So.. Is there any chance guest_memfd can in the future provide 1G normal
(!CoCo) pages?  If yes, are these pages GUP-able, and mapp-able?

Thanks,
