Stefano Stabellini e058632670 xen/arm,arm64: fix xen_dma_ops after 815dd18 "Consolidate get_dma_ops..." ... The following commit: commit 815dd18788 Author: Bart Van Assche <bart.vanassche@sandisk.com> Date: Fri Jan 20 13:04:04 2017 -0800 treewide: Consolidate get_dma_ops() implementations rearranges get_dma_ops in a way that xen_dma_ops are not returned when running on Xen anymore, dev->dma_ops is returned instead (see arch/arm/include/asm/dma-mapping.h:get_arch_dma_ops and include/linux/dma-mapping.h:get_dma_ops). Fix the problem by storing dev->dma_ops in dev_archdata, and setting dev->dma_ops to xen_dma_ops. This way, xen_dma_ops is returned naturally by get_dma_ops. The Xen code can retrieve the original dev->dma_ops from dev_archdata when needed. It also allows us to remove __generic_dma_ops from common headers.
