Actually, there are still cases where we're missing the annotations -
I've seen them in various oops dumps, but I forget where they are.
What I do remember is that they didn't seem trivial to fix at the
time, so it's still recommended that frame pointers are used if you
want to guarantee getting a debuggable oops dump.
