Ben Skeggs f29f18eb95 drm/nouveau: avoid GPU page sizes > PAGE_SIZE for buffer objects in host memory ... While the Tegra (GK20A, GM20B, GP10B) MMUs support large pages in host memory, we're currently lacking IOMMU support for merging system pages into large enough chunks to be mapped as such by the GPU. The core VMM code actually supports automatically determining the best page size to map with, which is intended for these situations, but for various complicated reasons the DRM is currently forcing the page size selection on a per-BO basis. This should fix breakage reported on Tegra GPUs in the meantime, until one or both of the above issues are resolved properly.
