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: 880 Lines: 27 This implementation is simply bogus - hexagon only has a simple direct mapped DMA implementation and thus doesn't care about the address.
