See http://www.infradead.org/rpr.html Sender: netdev-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: netdev@vger.kernel.org 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? Signed-off-by: Christoph Hellwig Acked-by: David S.
