If the TTM layer has used the DMA API to setup pages that are TTM_PAGE_FLAG_DMA32 (look at patch titled: "ttm: Utilize the DMA API for pages that have TTM_PAGE_FLAG_DMA32 set"), lets use it when programming the GART in the PCIe type cards. This patch skips doing the pci_map_page (and pci_unmap_page) if there is a DMA addresses passed in for that page. If the dma_address is zero (or DMA_ERROR_CODE), then we continue on with our old behaviour.
