    Impact: rq->buffer usage cleanup
    
    ide_raw_taskfile() directly uses rq->buffer to carry pointer to the
    data buffer.  This complicates both block interface and ide backend
    request handling.  Use blk_rq_map_kern() instead and drop special
    handling for REQ_TYPE_ATA_TASKFILE from ide_map_sg().
    
    Note that REQ_RW setting is moved upwards as blk_rq_map_kern() uses it
    to initialize bio rw flag.
