 Log Message:
 heartbeat(9): Use the cheaper and equally safe time_uptime32.
 
 Since we cache this every 15sec, and check it within a tick, there's
 no way for this to wrap around without first triggering a heartbeat
 panic.  So just use time_uptime32, the low 32 bits of the number of
 seconds of uptime -- cheaper on LP32 platforms.
 
 PR kern/58633: heartbeat(9) makes unnecessary use of time_uptime
