Maybe I'm missing a path, but are there any callers that still pass
STIME_MAX to reprogram_hpet_evt_channel()?
hpet_broadcast_exit() no longer explicitly passes STIME_MAX like it
did in e862b83e8433, and then the per-cpu timer_deadline variable is
not set to STIME_MAX either in timer_softirq_action().
Thanks, Roger.
