the mainstream kernel has merged *parts* of the RT patch. it does not
have all of it, and the last time i heard gleixner talk about it (last
fall, in portland, OR at the linux plumbers conf) he felt that it
unlikely that it would ever all be merged.

configuring your system for RT usage has ABSOLUTELY ZERO to do with
the presence or absence of the RT patch. RT scheduling, mlock and
other features used by RT applications are all available and usable on
all modern linux kernels. the RT patch just makes them work better, on
some machines, some of the time.
