This is illegal for at least two reasons: 1) While it may work on some platforms / iommus, obtaining page pointers from mapped sg-lists is illegal, since the DMA API allows page pointer information to be destroyed in the sg mapping process. 2) TTM has no way of determining the linear kernel map caching state of the underlying pages. PTEs with conflicting caching state pointing to the same pfn is not allowed. TTM operations touching pages of imported sg-tables should be redirected through the proper dma-buf operations.
