The -rt patch uses the lastest stuff from Thomas Gleixner, John Stultz and
of course Ingo Molnar. The functions you are interested in, are in
kernel/time/ directory. Take a look at clockevents.c and perhaps
handle_tick(). I'm not sure what LTTng is doing there, but this will give
you a direction in which way to look.
