Merge tag 'dma-mapping-4.16' of git://git.infradead.org/users/hch/dma-mapping
Pull dma mapping updates from Christoph Hellwig: "Except for a runtime warning fix from Christian this is all about consolidation of the generic no-IOMMU code, a well as the glue code for swiotlb. All the code is based on the x86 implementation with hooks to allow all architectures that aren't cache coherent to use it. The x86 conversion itself has been deferred because the x86 maintainers were a little busy in the last months" * tag 'dma-mapping-4.16' of git://git.infradead.org/users/hch/dma-mapping: (57 commits) MAINTAINERS: add the iommu list for swiotlb and xen-swiotlb arm64: use swiotlb_alloc and swiotlb_free arm64: replace ZONE_DMA with ZONE_DMA32 mips: use swiotlb_{alloc,free} mips/netlogic: remove swiotlb support tile: use generic swiotlb_ops tile: replace ZONE_DMA with ZONE_DMA32 unicore32: use generic swiotlb_ops ia64: remove an ifdef around the content of pci-dma.c ia64: clean up swiotlb support ia64: use generic swiotlb_ops ia64: replace ZONE_DMA with ZONE_DMA32 swiotlb: remove various exports swiotlb: refactor coherent buffer allocation swiotlb: refactor coherent buffer freeing swiotlb: wire up ->dma_supported in swiotlb_dma_ops swiotlb: add common swiotlb_map_ops swiotlb: rename swiotlb_free to swiotlb_exit x86: rename swiotlb_dma_ops powerpc: rename swiotlb_dma_ops ...
