During resume, tick_resume_broadcast() programs the broadcast timer in oneshot mode unconditionally. On the platforms where broadcast timer is not really required, this will generate spurious broadcast timer ticks upon resume. For example, on the always running apic timer platforms with HPET, I see spurious hpet tick once every ~5minutes (which is the 32-bit hpet counter wraparound time). Similar to boot time, during resume make the oneshot mode setting of the broadcast clock event device conditional on the state of active broadcast users.
