Modified Files: src/sys/arch/xen/xen: xen_clock.c Log Message: If Xen system time went backward, instead of ignoring the event assume one tick passed and reinitialise the local state. If we need to call the hardclock timer several time to catch up missed events, don't do more than one second in a single event; and schedule the next event faster. Hopefully fixes occasionnal panic: cpu1: time has not advanced in 1501 heartbeats or panic: cpu0: softints stuck for 16 seconds seen in daily Xen atf runs.
