Wu Zhangjin 7a7ac952d5 MIPS: Trace: Don't trace irqsoff for the idle process 
Like x86 did in arch/x86/kernel/{process_32.c,process_64.c}, also don't
trace irqsoff for idle.

If there's no useful work to be done, we don't care about the irqsoff
duration. If we trace the idle process, the max duration of irqsoff will
be the idle time and make the irqsoff tracer useless.
