All achitectures that do not define CONFIG_HAVE_DMA also have both of these definitions provided by dma-mapping-broken.h. Provide a default definition for the archs that define CONFIG_HAVE_DMA=y, but have no implementation for dma_{alloc,free}_attrs() by simply calling dma_{alloc,free}_coherent() and throwing away the attrs argument. Damian Hobson-Garcia (4): Provide default implementation for dma_{alloc,free}_attrs on arm64 Provide default implementation for dma_{alloc,free}_attrs on c6x Provide default implementation for dma_{alloc,free}_attrs on parisc Provide default implementation for dma_{alloc,free}_attrs on s390 arch/arm64/include/asm/dma-mapping.h | 3 +++ arch/c6x/include/asm/dma-mapping.h | 3 +++ arch/parisc/include/asm/dma-mapping.h | 3 +++ arch/s390/include/asm/dma-mapping.h | 3 +++ 4 files changed, 12 insertions(+), 0 deletions(-) -- 1.7.5.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
