Oh, apparently I never pushed out yesterday.

The patch literally just affects the (useless) hex number. So:

cat /proc/self/stack

now prints out

[<0>] proc_pid_stack+0xaa/0x100
[<0>] proc_single_show+0x48/0x80
[<0>] seq_read+0xd2/0x410

instead of putting some randomized kernel address there.

I considered getting rid of the whole "[<>]" thing, but that's where
"maybe there are tools that parse this" came in.

I doubt there are any, though. If proc-ps doesn't look at this, I
don't know what could. But the format change might as well be a
separate thing if somebody cares deeply.
