Pull CMA and DMA-mapping fixes from Marek Szyprowski:
 "Another set of minor fixups for recently merged Contiguous Memory
  Allocator and ARM DMA-mapping changes.  Those patches fix mysterious
  crashes on systems with CMA and Himem enabled as well as some corner
  cases caused by typical off-by-one bug."

* 'fixes-for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
  ARM: dma-mapping: modify condition check while freeing pages
  mm: cma: fix condition check when setting global cma area
  mm: cma: don't replace lowmem pages with highmem
