  dma-mapping: turn dma_cache_sync into a dma_map_ops method (2017-10-19 16:37:49 +0200)

----------------------------------------------------------------
A couple of dma-mapping updates:

 - 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)

----------------------------------------------------------------
Christoph Hellwig (11):
      floppy: consolidate the dummy fd_cacheflush definition
      x86: make dma_cache_sync a no-op
      frv: make dma_cache_sync a no-op
      ia64: make dma_cache_sync a no-op
      microblaze: make dma_cache_sync a no-op
      mn10300: make dma_cache_sync a no-op
      powerpc: make dma_cache_sync a no-op
      unicore32: make dma_cache_sync a no-op
      xtensa: make dma_cache_sync a no-op
      sh: make dma_cache_sync a no-op
      dma-mapping: turn dma_cache_sync into a dma_map_ops method

Robin Murphy (1):
      drivers: flag buses which demand DMA configuration
