Christoph Hellwig dff8d6c1ed swiotlb: remove the overflow buffer ... Like all other dma mapping drivers just return an error code instead of an actual memory buffer. The reason for the overflow buffer was that at the time swiotlb was invented there was no way to check for dma mapping errors, but this has long been fixed.
