Merge branch 'fixes-for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
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
