    Linus Torvalds authored
    Pull dma-mapping updates from Christoph Hellwig:
    
     - turn dma_cache_sync into a dma_map_ops instance and remove
       implementation that purely are dead because the architecture doesn't
       support noncoherent allocations
    
     - add a flag for busses that need DMA configuration (Robin Murphy)
