Nice!  Now the only thing missing is gettind kdb in mainline and a trace
reader in kdb ;-)

Any idea how easy it is to reuse the crash/gdb code for looking at crash
dumps through kgdb?

Btw, the Cc list here seems to be a very strong indicator that we
should have a linux-trace@vger list, I already noticed this for tons
of other tracing patches.
