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 both cases addressed here, these are simply static bidirectional mappings of scratch pages whose purpose is not...

This v4 is now a 3 piece series, 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.
