commit 7336375734d65ecc82956b59a79cf5deccce880c upstream.
Patch series "simplify follow_pte a bit".
This small series drops the not needed follow_pte_pmd exports, and simplifies the follow_pte family of functions a bit.
This patch (of 2):
follow_pte_pmd() is only used by the DAX code, which can't be modular.
