bnx2 fails to compile on parisc because of missing get_dma_ops()

[James Bottomley]

I'm not quite sure whose fault this one is.

However, this code in bnx2.c:

		if (!get_dma_ops(&pdev->dev)->sync_single_for_cpu) {
			next_rx_buf =
				&rxr->rx_buf_ring[
					RX_RING_IDX(NEXT_RX_BD(sw_cons))];
			prefetch(next_rx_buf->desc);
		}

Looks remarkably fragile: what exactly is it trying to do?

The commit that causes the problem:

commit a33fa66bcf365ffe5b79d1ae1d3582cc261ae56e
Author: Michael Chan <mchan@xxxxxxxxxxxx>
Date:   Thu May 6 08:58:13 2010 +0000

    bnx2: Add prefetches to rx path.

Looks fairly innocuous by the description.

Should parisc have a get_dma_ops()?  We don't need one because our dma
ops are per platform not per bus.
