    SubjectPATCH - use submit_bh in brw_kiovec

    Linus,
    the new submit_bh function provides functionality that is better
    suited for brw_kiovec to use than generic_make_request.

    This patch replaced generic_make_request with submit_bh in
    brw_kiovec and removed some field initialisation which is no longer
    required.

    patch against 2.4.0-test12-pre8
