Merge branch 'for-v3.12-fix' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping

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"
