Merge branch 'for-3.15' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull DMA-mapping updates from Marek Szyprowski:
"This contains extension for more efficient handling of io address
space for dma-mapping subsystem for ARM architecture"
* 'for-3.15' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
arm: dma-mapping: remove order parameter from arm_iommu_create_mapping()
arm: dma-mapping: Add support to extend DMA IOMMU mappings
