Hi Christoph, do you have any public git repository with all your dma changes? I want to test them for ARC. Thanks. On Fri, 2018-12-14 at 09:25 +0100, Christoph Hellwig wrote:
If we want to map memory from the DMA allocator to userspace it must be zeroed at allocation time to prevent stale data leaks. We already do this on most common architectures, but some architectures don't do this yet, fix them up, either by passing GFP_ZERO when we use the normal page allocator or doing a manual memset otherwise.
