Pull DMA-mapping fixes from Marek Szyprowski:
 "A set of minor fixes for dma-mapping code (ARM and x86) required for
  Contiguous Memory Allocator (CMA) patches merged in v3.5-rc1."

* 'fixes-for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
  x86: dma-mapping: fix broken allocation when dma_mask has been provided
  ARM: dma-mapping: fix debug messages in dmabounce code
  ARM: mm: fix type of the arm_dma_limit global variable
  ARM: dma-mapping: Add missing static storage class specifier
