This patch prepares p9_fcall structure for zero copy. Added fields send the payload buffer information to the transport layer. In addition it adds a 'private' field for the transport layer to store mapped/pinned page information so that it can be freed/unpinned during req_done. This patch also creates trans_common.[ch] to house helper functions. It adds the following helper functions. p9_release_req_pages - Release pages after the transaction. p9_nr_pages - Return number of pages needed to accomodate the payload. payload_gup - Translates user buffer into kernel pages.
