arm64: use the generic swiotlb_dma_ops (2018-10-19 08:53:24 +0200)
---------------------------------------------------------------- Second batch of dma-mapping updates for 4.20:
- various swiotlb cleanups - do not dip into the ѕwiotlb pool for dma coherent allocations - add support for not cache coherent DMA to swiotlb - switch ARM64 to use the generic swiotlb_dma_ops
---------------------------------------------------------------- Christoph Hellwig (10): swiotlb: remove a pointless comment swiotlb: mark is_swiotlb_buffer static swiotlb: do not panic on mapping failures swiotlb: remove the overflow buffer swiotlb: merge swiotlb_unmap_page and unmap_single swiotlb: use swiotlb_map_page in swiotlb_map_sg_attrs swiotlb: refactor swiotlb_map_page swiotlb: don't dip into swiotlb pool for coherent allocations swiotlb: add support for non-coherent DMA arm64: use the generic swiotlb_dma_ops
