Subject[PATCH -rt 4/9] ifdef raise_softirq_irqoff wakeup
raise_softirq is called every timer interrupt in run_local_timers(),
which causes a thread wakeup to happen every timer interrupt. This
happens in !CONFIG_PREEMPT_SOFTIRQS, which means the wakeup is most
likely not needed. In addition it also fouls calc_load() since it's,
agian, observing at least one thread running on every invocation.
