Ugh. This is somewhat invasive, I worry that some header include or
architecture doesn't pick up on the subtle __PAGETABLE_XYZ_FOLDED
things (if you don't get the includes, the mm_xyz_folded() maros will
be mis-defined.

Has this been in linux-next or any other wide testing? The changes
aren't _new_, but...
