I'm actually inclined to try exactly that for 4.3, and then take
Ingo's patch as a fallback in case somebody actually notices.

I'm not convinced anybody actually uses those values, and they are
getting *less* relevant rather than more (on 64-bit, those values
really don't matter, since the vmalloc space isn't really a
limitation), so let's try removing them and seeing what happens. And
then we know what we can do if somebody does actually notice.
