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." * 'fixes-for-v3.8-rc7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: xtensa: Provide dummy dma_mmap_coherent() and dma_get_sgtable() parisc: Provide dummy dma_mmap_coherent() and dma_get_sgtable() mn10300: Provide dummy dma_mmap_coherent() and dma_get_sgtable() m68k: Provide dma_mmap_coherent() and dma_get_sgtable() frv: Provide dummy dma_mmap_coherent() and dma_get_sgtable() cris: Provide dma_mmap_coherent() and dma_get_sgtable() c6x: Provide dummy dma_mmap_coherent() and dma_get_sgtable() blackfin: Provide dma_mmap_coherent() and dma_get_sgtable() avr32: Provide dma_mmap_coherent() and dma_get_sgtable()
