I think you should persist with anon_vma and I should resurrect
anonmm, and let others decide between those two and pte_chains.

But while in this trial phase, can we both do it in such a way as to
avoid too much trivial change all over the tree?  For example, I'm
thinking I need to junk my irrelevant renaming of put_dirty_page to
put_stack_page, and for the moment it would help if you cut out your
mapping -> as.mapping changes (when I came to build yours, I had to
go through various filesystems I had in my config updating them
accordingly).  It's a correct change (which I was too lazy to do,
used evil casting instead) but better left as a tidyup for later?
