Yes that's clearly how it should be. Unfortunately while adding the locking to do this, I found out that you can't actually call __vmalloc with BH disabled so this is a no-go. Unless we can make __vmalloc work with BH disabled, I guess we'll have to go back to multi-level lookups unless someone has a better suggestion.
