   grant suggested adding support for it had performance implications,
   so he wasn't willing to let me make that edit.  i'm not sure i entirely
   understand the new scheme either.  the danger of updating code without
   updating its supporting documentation.

If "address" is NULL, use page+offset.  It's pretty simple.
