Is there any reason why we don't do a dump_stack on panic? I find this soooo useful in the -rt patch, where Ingo has placed a dump_stack on panic. With mainline, when I hit a panic, I don't always know how it got there. So I find myself adding the dump_stack and trying to create the bug again.
This patch simply adds dump_stack to panic.
