Merge branch 'for-v3.18' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull dma-mapping update from Marek Szyprowski: "Provide the dma write coherent api (available previously on ARM architecture) for all other architectures, which use dma_ops-based dma mapping implementation. This lets one to use the same code in the device drivers regardless of the selected architecture" * 'for-v3.18' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: dma-mapping: Provide write-combine allocations s390: Implement dma_{alloc,free}_attrs()
