Please note that the __rcudle() tracepoints depend on patch #45 from
my series (https://lkml.org/lkml/2012/2/3/471), though only for code
containing tracepoints that are called both from idle and non-idle.
I believe that the tracepoints in this patch series are only invoked
from idle, so should be no problem.
Thanx, Paul
