See http://www.infradead.org/rpr.html Cc: linux-kernel@vger.kernel.org Subject: [Xen-devel] [PATCH 27/44] sparc: remove leon_dma_ops X-BeenThere: xen-devel@lists.xen.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Errors-To: xen-devel-bounces@lists.xen.org Sender: "Xen-devel" X-Virus-Scanned: ClamAV using ClamSMTP 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.
