Mike Miller (OS Dev) 8bf50f71cb cciss: disable DMA refetch on Smart Array P600 
This patch disables DMA refetch in the PCI bridge. We have disabled DMA
prefetch for quite some time. Testing with XEN revealed another ASIC bug. If
dom0 resides on a P600 the board can can an MCA bi accessing invalid memory
addresses. Apparently, we need to disable both prefetch and refetch.
My understanding is a refetch operation should not occur but it is a valid
thing to do if prefetched data is no longer available for whatever reason.
Please consider this patch for inclusion.
