Subpage seems like a fairly bad name.  page_frag would fit into the
scheme used in a few other places.

The brings back the discussion of unifying the various incarnations we
have of this (biovec, skb frag and there were a few more at times),
but IIRC one of the sticking points back then was that one offset
insistet in 32-bit offset/len and the other on 16-bit.
