    sched/clock: Delay switching sched_clock to stable · 9881b024
    Peter Zijlstra authored
    Currently we switch to the stable sched_clock if we guess the TSC is
    usable, and then switch back to the unstable path if it turns out TSC
    isn't stable during SMP bringup after all.
    
    Delay switching to the stable path until after SMP bringup is
    complete. This way we'll avoid switching during the time we detect the
    worst of the TSC offences.
