Each architecturee must provide a definition of mk_pte() today. They must also provide pfn_pte(). Usually the former is defined in terms of the latter, but not on some architectures. I was trying to decide what we should do for creating PTEs in a folio world, and it struck me that we should have architectures only provide pfn_pte() and then I don't need to trouble the arch maintainers with whatever MM API I come up with. The architectures not on the cc list I considered trivial. The architectures who have named patches are less trivial, and I did my best to write a decent commit message explaining why I did what I did to each architecture. I have some followup patches which remove folio->page conversions, but if this set of patches are wrong on any architecture, then they'll also be wrong, so I'm not sending them right now.
