drm/vmwgfx: Use the linux DMA api to get valid device addresses of pages The code handles three different cases: 1) physical page addresses. The ttm page array is used. 2) DMA subsystem addresses. A scatter-gather list is used. 3) Coherent pages. The ttm dma pool is used, together with the dma_ttm array os dma_addr_t Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Jakob Bornecrantz <jakob@vmware.com>
