Date: Fri, 16 Feb 2007 10:50:58 -0800 From: "Gary Zambrano" <zambrano@...adcom.com> To: jgarzik@...ox.com cc: linux-kernel@...r.kernel.org, akpm@...l.org, netdev@...r.kernel.org Subject: [PATCH] dma-mapping.h Added dma_sync_single_range_for_cpu/device to dma-mapping.h in asm-arm & asm-avr32 to call dma_sync_single_for_cpu/device. This patch enables b44 to compile on systems with these cpus. This patch was created with the assumption that another method of dma_sync_single_range_for_cpu/device does not exist on these architectures.
