See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1903 Lines: 57 We can just use pci32_dma_ops. Btw, given that leon is 32-bit and appears to be PCI based, do even need the special case for it in get_arch_dma_ops at all?
