[PATCH] x86_64: GART DMA merging fix
Don't touch the non DMA members in the sg list in dma_map_sg in the IOMMU
Some drivers (in particular ST) ran into problems because they reused the sg
lists after passing them to pci_map_sg(). The merging procedure in the K8
GART IOMMU corrupted the state. This patch changes it to only touch the dma*
entries during merging, but not the other fields. Approach suggested by Dave
Miller.
