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()
