Roughly, what I am thinking (limiting it to pte+pmd case) about is 
the following:

I cannot get the below to apply even with the original patch here 
applied + fix.

It looks like (in mm-new :) commit e73f43a66d5f ("mm/gup: remove dead 
pgmap
refcounting code") by Alastair has conflicted here, but even then I 
can't make
it apply, with/without your fix...!

I eventually resorted to telling the local AI to read the diffs and
apply them on top of the nth_page series locally. :) Attaching the
resulting patch, which worked well enough to at least see the proposal
clearly.

To be clear: it was never intended to be applied, because it wouldn't 
even compile in the current form.

It was based on this nth_page submission + fix.

thanks,
