    parisc: Mark cr16 clocksource unstable on SMP systems · 41744213
    Helge Deller authored
    The cr16 interval timer of each CPU is not syncronized to other cr16
    timers in other CPUs in a SMP system. So, delay the registration of the
    cr16 clocksource until all CPUs have been detected and then - if we are
    on a SMP machine - mark the cr16 clocksource as unstable and lower it's
    rating before registering it at the clocksource framework.
    
    This patch fixes the stalled CPU warnings which we have seen since
    introduction of the cr16 clocksource.
