Only skimmed over it, nothing jumped at me except ...

Nitpicking:

I was wondering if "page mask" really the right term here. I know that we use it in some context (gup, hugetlb, zeropage) to express "mask this off and you get the start of the aligned huge page".

For something that walks PFNMAPs (page frames without any real "huge page" logical metadata etc. grouping) it was uintuitive for me at first.

addr_mask or pfn_mask (shifted addr_mask) would have been clearer for me.

No strong opinion, just what came to mind while reading this ...
