- More SCSI port defs. - Nuke vtophys(). - Release resources in iop_init() upon failure. - Don't use a message wrapper when initalising the outbound FIFO. - A couple of field size/endian fixes. - Just use iop_post() when we don't need special handling. - IM_DISCARD is now pointless, since we don't queue at the driver level. - Map data transfers from/to userspace directly. - A few comment and stylistic changes.
