Wait... what the heck is a "special" page? Isn't that a terrible name for _anything_? Or is there a tradition to the name? It sounds like it should be named "novma" or "autonomous" or something instead. Something that carries at least a little more information than "special". Where can I find the documentation for this bit?
Has this been discussed on LKML? Is the name a result of consensus or whim?
Help! :-)
