Finer-grained locking for kretprobes
Here's a mostly-untested, i386-only patch that I put together in my spare time
quite a while ago. I meant to test it on an SMP system before posting it, but
I haven't found the time. But I don't want the work to go to waste, so here it
is. The patch is described in its preamble.
