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
