When running on Xen as initial domain, we always want xen_dma_ops to be the one in use. We introduce __generic_dma_ops to allow xen_dma_ops functions to call back to the native implementation. Signed-off-by: Stefano Stabellini Acked-by: Catalin Marinas CC: will.deacon@arm.com Changes in v7: - return xen_dma_ops only if we are the initial domain; - rename __get_dma_ops to __generic_dma_ops. --- Reading git-diff-tree failed
