This v4 is now a 3 piece series (since v4), after Alexandre pointed out that both GF 100 and NV50 are affected by the same issue, and that a related issue has been solved already for Tegra in commit 9d0394c6bed5 ("drm/nouveau/instmem/gk20a: set DMA mask early"). The issue that this series addresses is the fact that the Nouveau driver invokes the DMA API before setting the DMA mask. In

TTM-allocated coherent objects were populated using the DMA API and accessed using the mapping it returned to workaround coherency issues. These issues seem to have been solved, thus remove this extra case to handle and use the regular kernel mapping functions.
