Splitting must be entirely logarithmic

Parent article: Scaling transparent huge pages to 1GB

It's actually fairly trivial. We assume that any PMD we find contains the head page of a folio. We also assume the inverse, that if we're creating a PMD that we want it to point to the first 2MB of a folio. It really is a SMOP to fix, it's just finding all the places that make that assumption and testing the result is a pain.
