Alistair Popple 349994cf61 mm/rmap: add support for PUD sized mappings to rmap
The rmap doesn't currently support adding a PUD mapping of a folio.  This
patch adds support for entire PUD mappings of folios, primarily to allow
for more standard refcounting of device DAX folios.  Currently DAX is the
only user of this and it doesn't require support for partially mapped
PUD-sized folios so we don't support for that for now.
