-         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

-         Most drivers don't have this problem; it is safe to say Y here.
