    That's not enough, right now on x86 this code needs special
    architecture glue, see how the noirqtime flag is used to call
    into enable_sched_clock_irqtime() after TSC init.

    So if you apply your patch and boot CONFIG_IRQ_TIME_ACCOUNTING=y
    on say an ARM system, nothing will be done, because
    sched_clock_irqtime is always zero.

    Thanks,

    Ingo
