Merge tag 'dma-mapping-4.15' of git://git.infradead.org/users/hch/dma-mapping
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) * tag 'dma-mapping-4.15' of git://git.infradead.org/users/hch/dma-mapping: dma-mapping: turn dma_cache_sync into a dma_map_ops method sh: make dma_cache_sync a no-op xtensa: make dma_cache_sync a no-op unicore32: make dma_cache_sync a no-op powerpc: make dma_cache_sync a no-op mn10300: make dma_cache_sync a no-op microblaze: make dma_cache_sync a no-op ia64: make dma_cache_sync a no-op frv: make dma_cache_sync a no-op x86: make dma_cache_sync a no-op floppy: consolidate the dummy fd_cacheflush definition drivers: flag buses which demand DMA configuration
