[PATCH] optimize activate_task()
recalc_task_prio() is called from activate_task() to calculate dynamic
priority and interactive credit for the activating task. For real-time
scheduling process, all that dynamic calculation is thrown away at the end
because rt priority is fixed. Patch to optimize recalc_task_prio() away
for rt processes.
