Please ignore this patch if frv doesn't use dma_map_page() and dma_map_single() from arch/mips/include/asm/dma-mapping. frv defines dma_map_page() and dma_map_single() in arch/frv/mb93090-mb00/pci-dma.c and arch/frv/mb93090-mb00/pci-dma-nommu.c -- Shuah > --- > arch/frv/include/asm/dma-mapping.h | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/arch/frv/include/asm/dma-mapping.h > b/arch/frv/include/asm/dma-mapping.h > index dfb8110..d8a8aac 100644 > --- a/arch/frv/include/asm/dma-mapping.h > +++ b/arch/frv/include/asm/dma-mapping.h > @@ -6,6 +6,7 @@ > #include <asm/cacheflush.h> > #include <asm/scatterlist.h> > #include <asm/io.h> > +#include <linux/dma-debug.h> > > /* > * See Documentation/DMA-API.txt for the description of how the > @@ -97,6 +98,7 @@ void dma_sync_sg_for_device(struct device *dev, struct > scatterlist *sg, int nele > static inline > int dma_mapping_error(struct device *dev, dma_addr_t dma_addr) > { > + debug_dma_mapping_error(dev, dma_addr); > return 0; > } > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
