Randomizing the kernel

Randomizing the kernel

This seems like a very simple and worthwhile step. Ubuntu has kptr_restrict turned on but it's useless without randomization.

It's true that there are still lots of information leaks left. Smatch has a check for some kinds of trivial leaks. I fixed a couple leaks last week.

But if you just keep on plugging away at it, these do get fixed eventually. The quality of kernel code really is getting better. I think of things like this as part of a five year project instead of as an end in themselves.
