So I'd find a patch like the attached to be perfectly acceptable (in
fact, we should have done this long ago).

That said, for a kernel hardening thing, I think it would be much more
important to just make sure that KASLR is enabled much more. Right now
I think it's disabled in practice if you enable hibernation support,
and I think most distros do that.

So I think that in *practice*, kaslr is much more likely to be
defeated by much more mundane reasons.
