Regarding the fixlet below - wouldnt PTE_FLAGS_MASK be better placed in

have a lot of PTE details in the page_*types.h files already.

No, you're right.

The boundary between page_types.h and pgtable_types.h does not seem to
be clear to me - what is the principle you followed?

Well, basically anything to do with the internals of a pte*_t go in pgtable.h. PTE_*_MASK should go there too, and is an oversight (though its on the margin because of its dependency on the page size/mask definitions in page*.h).
