Maxime Coquelin d7b4e3287c vduse: implement DMA sync callbacks ... Since commit 295525e29a ("virtio_net: merge dma operations when filling mergeable buffers"), VDUSE device require support for DMA's .sync_single_for_cpu() operation as the memory is non-coherent between the device and CPU because of the use of a bounce buffer. This patch implements both .sync_single_for_cpu() and .sync_single_for_device() callbacks, and also skip bounce buffer copies during DMA map and unmap operations if the DMA_ATTR_SKIP_CPU_SYNC attribute is set to avoid extra copies of the same buffer.
