Merge branch 'for-v3.12' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull DMA mapping update from Marek Szyprowski: "This contains an addition of Device Tree support for reserved memory regions (Contiguous Memory Allocator is one of the drivers for it) and changes required by the KVM extensions for PowerPC architectue" * 'for-v3.12' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: ARM: init: add support for reserved memory defined by device tree drivers: of: add initialization code for dma reserved memory drivers: of: add function to scan fdt nodes given by path drivers: dma-contiguous: clean source code and prepare for device tree
