The only user of devmap PTEs is FS DAX, and khugepaged should not be

Note this is a transitory patch to test the above assumption both at

gets deleted when pXX_devmap is removed.
Yes, doesn't make sense for this patch to exist if it would go upstream
along with the next patch that removes that completely.
