Actually, while I've always looked at the 36-bit extensions with extreme distaste, Stephen Tweedie convinced me that we can really cleanly and fairly easily support it in a perfectly reasonable manner. It won't be 100% support, but it looks better than just using it as a ramdisk (we can basically use it for page caches and anonymous pages without having to get ugly about it - they have enough of an abstraction layer that it doesn't impact the rest of the system much at all)
So we may actually end up with a reasonable support for it. The page cache and anonymous memory is really what people want anyway, other memory uses are basically "fluff" compared to those two.
We'll see. The proof is in the code, and while Stephen made a very good case for something that I would accept, we'll just have to see how it works out. Right now the alpha/sparc64 approach is still the only reasonable choice with Linux.
