The last two steps have nothing to do with any kernel patch. They
simply allow non-root users to use realtime scheduling, which is useful
for pro audio no matter what kernel you run.
Con's patches are intended to improve interactivity for gaming and
desktop stuff where everything runs at the same priority and the
scheduler has to basically guess who to give the CPU to. They should
have no effect on pro audio applications, which explicitly request a
high-priority scheduling class.
