Honestly, GPL (or more permissive) is the only thing that really makes sense. Much of the documentation, once processed, includes an awful lot of stuff directly from the kernel source; there's really no way to say that it's not a derived product of the kernel. So the output of "make htmldocs" or "make pdfdocs" really has to be GPL, suggesting that the input should be GPL-compatible.
GPL isn't the best license for documentation. If we were starting today I'd try to find a way to use CC-SA instead, but that's not where we're at. And GPL is workable enough, I think.
At least that's how I see it, not that I really know any more than anybody else.
