This patch series fixes usage of the etnaviv driver with GPUs behind a IOMMU. It was tested on a NXP LS1028A SoC. Together with Lucas' MMU patches [1] there are not more (GPU internal) MMU nor (system) IOMMU faults on the LS1028A.

changes since v1: - don't move the former dma_mask setup code around in patch 2/3. Will avoid any confusion.
