Merge tag 'dma-mapping-4.14' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping updates from Christoph Hellwig: - removal of the old dma_alloc_noncoherent interface - remove unused flags to dma_declare_coherent_memory - restrict OF DMA configuration to specific physical busses - use the iommu mailing list for dma-mapping questions and patches * tag 'dma-mapping-4.14' of git://git.infradead.org/users/hch/dma-mapping: dma-coherent: fix dma_declare_coherent_memory() logic error ARM: imx: mx31moboard: Remove unused 'dma' variable dma-coherent: remove an unused variable MAINTAINERS: use the iommu list for the dma-mapping subsystem dma-coherent: remove the DMA_MEMORY_MAP and DMA_MEMORY_IO flags dma-coherent: remove the DMA_MEMORY_INCLUDES_CHILDREN flag of: restrict DMA configuration dma-mapping: remove dma_alloc_noncoherent and dma_free_noncoherent i825xx: switch to switch to dma_alloc_attrs au1000_eth: switch to dma_alloc_attrs sgiseeq: switch to dma_alloc_attrs dma-mapping: reduce dma_mapping_error inline bloat
