These patches makes the vmwgfx driver use the DMA API to obtain valid
device addresses rather than blindly using physical addresses.
The main motivation is to be able to use a virtual IOMMU in the future.
Other TTM drivers typically map pages one by one rather than using a
scatter-gather list, bu
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
