What has DMA to do with that? We're talking about alignment only. > At least in the kernel, we don't use stack for DMA buffers. Yes, but them, the kernel uses a much more complicated memory setup, with somewhat different mappings for different regions. We don't do that - or do we? IMO we use a single mapping for the whole RAM ?
