          Cause IO segments sent to a device for DMA to be merged virtually
          by the IOMMU when they happen to have been allocated contiguously.
          This doesn't add pressure to the IOMMU allocator. However, some
          drivers don't support getting large merged segments coming back
-         from *_map_sg(). Say Y if you know the drivers you are using are
-         properly handling this case.
