AFAIK, UVM was a big step in the way Chuck Cranor disposed of multi-layer object heirarchies, which do not exist in Linux anyways. But I am incompetent, so dig out Chuck's USENIX-99 presentation. That should explain how he extracts any performance advantages.
Rik van Riel is working on a Linux VM rewrite which looks interesting to me. I do not know of any whitepapers coming from his direction, so you need to dig linux-kernel archives. His patch may have a UVM-like effect on the performance. --Pete
