    dma-mapping: remove CONFIG_ARCH_NO_COHERENT_DMA_MMAP · 62fcee9a
    Christoph Hellwig authored
    CONFIG_ARCH_NO_COHERENT_DMA_MMAP is now functionally identical to
    !CONFIG_MMU, so remove the separate symbol.  The only difference is that
    arm did not set it for !CONFIG_MMU, but arm uses a separate dma mapping
    implementation including its own mmap method, which is handled by moving
    the CONFIG_MMU check in dma_can_mmap so that is only applies to the
    dma-direct case, just as the other ifdefs for it.
