           Summary: Bad use of GFP_DMA in S390 drivers
    Kernel Version: 2.5.63
            Status: NEW
          Severity: normal
             Owner: com.ibm at arndb.de
         Submitter: willy at debian.org


GFP_DMA should always be ORed with GFP_ATOMIC or GFP_KERNEL, not used
by itself:

./drivers/s390/cio/css.c:       sch = kmalloc (sizeof (*sch), GFP_DMA);
./drivers/s390/cio/device.c:    cdev->private = kmalloc(sizeof(struct
ccw_device_private), GFP_DMA);
./drivers/s390/cio/device_ops.c:        rcd_buf = kmalloc(ciw->count, GFP_DMA);
./drivers/s390/cio/qdio.c:      irq_ptr=kmalloc(sizeof(struct
qdio_irq),GFP_DMA);
./drivers/s390/cio/qdio.c:      irq_ptr->qdr=kmalloc(sizeof(struct
qdr),GFP_DMA);
./drivers/s390/net/netiucv.c:           conn->rx_buff =
alloc_skb(NETIUCV_BUFSIZE_DEFAULT, GFP_DMA);
./drivers/s390/net/netiucv.c:           conn->tx_buff =
alloc_skb(NETIUCV_BUFSIZE_DEFAULT, GFP_DMA);
