      Merge branch 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping · 58bca4a8

      Pull DMA mapping branch from Marek Szyprowski:
       "Short summary for the whole series:
      
        A few limitations have been identified in the current dma-mapping
        design and its implementations for various architectures.  There exist
        more than one function for allocating and freeing the buffers:
        currently these 3 are used dma_{alloc, free}_coherent,
        dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent.
      
        For most of the systems these calls are almost equivalent and can be
        interchanged.  For others, especially the truly non-coherent ones
        (like ARM), the difference can be easily noticed in overall driver
        performance.  Sadly not all architectures provide implementations for
        all of them, so the drivers might need to be adapted and cannot be
        easily shared between different architectures.  The provided patches
        unify all these functions and hide the differences under the already
        existing dma attributes concept.  The thread with more references is
        available here:
      
          http://www.spinics.net/lists/linux-sh/msg09777.html
      
        These patches are also a prerequisite for unifying DMA-mapping
        implementation on ARM architecture with the common one provided by
        dma_map_ops structure and extending it with IOMMU support.  More
        information is available in the following thread:
      
          http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819
      
        More works on dma-mapping framework are planned, especially in the
        area of buffer sharing and managing the shared mappings (together with
        the recently introduced dma_buf interface: commit d15bd7ee
        "dma-buf: Introduce dma buffer sharing mechanism").
      
        The patches in the current set introduce a new alloc/free methods
        (with support for memory attributes) in dma_map_ops structure, which
        will later replace dma_alloc_coherent and dma_alloc_writecombine
        functions."
      
      People finally started piping up with support for merging this, so I'm
      merging it as the last of the pending stuff from the merge window.
      Looks like pohmelfs is going to wait for 3.5 and more external support
      for merging.
