Merge branch 'fixes-for-v3.8-rc7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull DMA mapping fixes from Marek Szyprowski:
"This pull request contains important bugfix patches for 9
architectures, which finally fixes broken allmodconfig builds
introduced in v3.8-rc1. Those architectures don't use dma_map_ops
based implementation and require manual update or additional dummy
implementations of the missing new dma-mapping api functions:
dma_mmap_coherent and dma_get_sgtable."
