Linus Torvalds 18b0bbd8ca Fix nasty /proc vulnerability ...

We have a bad interaction with both the kernel and user space being able
to change some of the /proc file status.  This fixes the most obvious
part of it, but I expect we'll also make it harder for users to modify
even their "own" files in /proc.
