    Adapt core SH architecture code for dma_map_ops changes: replace
    alloc/free_coherent with generic alloc/free methods.

  • 3b9c6c11f   dma-mapping: remove dma_is_consistent API ... Browse Code »

    Architectures implement dma_is_consistent() in different ways (some
    misinterpret the definition of API in DMA-API.txt). So it hasn't been so
    useful for drivers. We have only one user of the API in tree. Unlikely
    out-of-tree drivers use the API.

    Even if we fix dma_is_consistent() in some architectures, it doesn't look
    useful at all. It was invented long ago for some old systems that can't
    allocate coherent memory at all. It's better to export only APIs that are
    definitely necessary for drivers.

    Let's remove this API.

  • 4565f0170   dma-mapping: unify dma_get_cache_alignment implementations ... Browse Code »

    dma_get_cache_alignment returns the minimum DMA alignment. Architectures
    defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we
    can unify dma_get_cache_alignment implementations.

    Note that some architectures implement dma_get_cache_alignment wrongly.
    dma_get_cache_alignment() should return the minimum DMA alignment. So
    fully-coherent architectures should return 1. This patch also fixes this
    issue.

  • 621266bdf   sh: Quiet noisy coherent DMA unmapping on R2D. ... Browse Code »

    IRQs are re-enabled at a later stage when doing the unmapping on R2D via
    the sm501 USB coherent DMA, resulting in the irqs_disabled() check
    producing considerable noise for this configuration. Just kill off the
    check, which was blindly copied from x86 anyways.

    commit dbe6f1869188b6e04e38aa861dd198befb08bcd7
    ("dma-mapping: mark dma_sync_single and dma_sync_sg as deprecated"
    conveniently broke every single SH build.

    In the future it would be great if people could at least bother
    figuring out how to use grep.

    This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.

    Most of the moving about was done with Sam's directions at:

    with subsequent hacking and fixups entirely my fault.
