Merge branch 'for-linus-for-3.6-rc1' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull DMA-mapping updates from Marek Szyprowski: "Those patches are continuation of my earlier work. They contains extensions to DMA-mapping framework to remove limitation of the current ARM implementation (like limited total size of DMA coherent/write combine buffers), improve performance of buffer sharing between devices (attributes to skip cpu cache operations or creation of additional kernel mapping for some specific use cases) as well as some unification of the common code for dma_mmap_attrs() and dma_mmap_coherent() functions. All extensions have been implemented and tested for ARM architecture." * 'for-linus-for-3.6-rc1' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: ARM: dma-mapping: add support for DMA_ATTR_SKIP_CPU_SYNC attribute common: DMA-mapping: add DMA_ATTR_SKIP_CPU_SYNC attribute ARM: dma-mapping: add support for dma_get_sgtable() common: dma-mapping: introduce dma_get_sgtable() function ARM: dma-mapping: add support for DMA_ATTR_NO_KERNEL_MAPPING attribute common: DMA-mapping: add DMA_ATTR_NO_KERNEL_MAPPING attribute common: dma-mapping: add support for generic dma_mmap_* calls ARM: dma-mapping: fix error path for memory allocation failure ARM: dma-mapping: add more sanity checks in arm_dma_mmap() ARM: dma-mapping: remove custom consistent dma region mm: vmalloc: use const void * for caller argument scatterlist: add sg_alloc_table_from_pages function
