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(). As I don't have hardware for any of these systems, the patches are only compile-tested where I could (arm64, s390) and untested for the archs where I couldn't find a readily available prebuilt cross-compiler (c6x, parisc). Changes from v1 --------------- arm64, s390: * Since these archs are using dma_ops, pass appropirate value for attrs to dma_ops->alloc(). * Indicate that these patches are compile teseted only (I don't have hardware) c6x, parisc: * Indicate that these patches are untested (I don't have cross compilers) Cheers, Damian Damian Hobson-Garcia (4): arm64: Provide default implementation for dma_{alloc,free}_attrs c6x: Provide default implementation for dma_{alloc,free}_attrs parisc: Provide default implementation for dma_{alloc,free}_attrs s390: Provide default implementation for dma_{alloc,free}_attrs arch/arm64/include/asm/dma-mapping.h | 17 +++++++++++------ arch/c6x/include/asm/dma-mapping.h | 3 +++ arch/parisc/include/asm/dma-mapping.h | 3 +++ arch/s390/include/asm/dma-mapping.h | 17 +++++++++++------ 4 files changed, 28 insertions(+), 12 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/
