Pull DMA-mapping fix from Marek Szyprowski:
"A build bugfix for the device tree support for reserved memory
regions. Due to superfluous include the common code failed to build
on ARM64 and MIPS architectures.
The patch that caused the build break has lived at linux-next for
about two weeks and noone noticed the issue, what convinced me that
everything was ok"
* 'for-v3.12-fix' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
drivers: of: fix build break if asm/dma-contiguous.h is missing
