It has been a couple of months since v4 - apologies for this. v4 has not received many comments, but this version addresses them and makes a new attempt at pushing the critical bit for GK20A and Nouveau on ARM in general. As a reminder, this series addresses the memory coherency issue that we are seeing on ARM platforms. Contrary to x86 which invalidates the PCI caches whenever a write is made by

Another revision of this patchset critical for GK20A to operate. Previous attempts were exclusively using either TTM's regular page allocator or the DMA API one. Both have their advantages and drawbacks: the page allocator is fast but requires explicit synchronization on non-coherent architectures, whereas the DMA allocator always returns coherent memory, but is also slower, creates a
