    Impact: per CPU hrtimers can be migrated from a dead CPU
    
    The hrtimer code has no knowledge about per CPU timers, but we need to
    prevent the migration of such timers and warn when such a timer is
    active at migration time.
    
    Explicitely mark the timers as per CPU and use a more understandable
    mode descriptor for the interrupts safe unlocked callback mode, which
    is used by hrtimer_sleeper and the scheduler code.
