Converted to what?

drivers/scsi/sr_ioctl.c:	buffer = kmalloc(32, GFP_KERNEL | SR_GFP_DMA(cd));
drivers/scsi/sr_ioctl.c:	buffer = kmalloc(32, GFP_KERNEL | SR_GFP_DMA(cd));
drivers/scsi/sr_ioctl.c:	char *buffer = kmalloc(32, GFP_KERNEL | SR_GFP_DMA(cd));
drivers/scsi/sr_ioctl.c:	raw_sector = kmalloc(2048, GFP_KERNEL | SR_GFP_DMA(cd));
drivers/scsi/sr.c:	buffer = kmalloc(512, GFP_KERNEL | GFP_DMA);
drivers/scsi/sr.c:	buffer = kmalloc(512, GFP_KERNEL | GFP_DMA);
drivers/scsi/ch.c:	buffer = kmalloc(512, GFP_KERNEL | GFP_DMA);
drivers/scsi/ch.c:		buffer = kmalloc(512, GFP_KERNEL | GFP_DMA);

^^^ looks generic to mme.

drivers/net/tokenring/3c359.c:	xl_priv->xl_tx_ring = kmalloc((sizeof(struct xl_tx_desc) * XL_TX_RING_SIZE) + 7, GFP_DMA | GFP_KERNEL) ; 
drivers/net/tokenring/3c359.c:	xl_priv->xl_rx_ring = kmalloc((sizeof(struct xl_rx_desc) * XL_RX_RING_SIZE) +7, GFP_DMA | GFP_KERNEL) ; 

Tokenring not supported on x86?

drivers/net/znet.c:	if (!(znet->rx_start = kmalloc (DMA_BUF_SIZE, GFP_KERNEL | GFP_DMA)))
drivers/net/znet.c:	if (!(znet->tx_start = kmalloc (DMA_BUF_SIZE, GFP_KERNEL | GFP_DMA)))
drivers/net/lance.c:			rx_buff = kmalloc(PKT_BUF_SZ, GFP_DMA | gfp);
drivers/net/wan/cosa.c:	cosa->bouncebuf = kmalloc(COSA_MTU, GFP_KERNEL|GFP_DMA);
drivers/net/wan/cosa.c:	if ((chan->rxdata = kmalloc(COSA_MTU, GFP_DMA|GFP_KERNEL)) == NULL) {
drivers/net/wan/cosa.c:	if ((kbuf = kmalloc(count, GFP_KERNEL|GFP_DMA)) == NULL) {

None of the above are supported on x86?
