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
