    common: dma-mapping: add support for generic dma_mmap_* calls · 64ccc9c0
    Marek Szyprowski authored
    Commit 9adc5374 ('common: dma-mapping: introduce mmap method') added a
    generic method for implementing mmap user call to dma_map_ops structure.
    This patch converts ARM and PowerPC architectures (the only providers of
    dma_mmap_coherent/dma_mmap_writecombine calls) to use this generic
    dma_map_ops based call and adds a generic cross architecture
    definition for dma_mmap_attrs, dma_mmap_coherent, dma_mmap_writecombine
    The generic mmap virt_to_page-based fallback implementation is provided for
    architectures which don't provide their own implementation for mmap method.
