[RFC LINUX PATCH 0/2] Virtio ring works with DMA coherent memory
...dress back from the virtual address, and thus,
we can set the sg_dma_addr to store the DMA address and mark it already DMA
mapped.
When virtio vring sees the sg_dma_addr is ready set, do not call dma_map_page().
The issue was once discussed here:

rpmsg: DMA map sgs passed to virtio
Wendy Liang (1):
virtio_ring: Do not call dma_map_page if sg is already mapped.
