While the default "info lapic" always synchronizes cpu state ... mon_get_cpu() -> mon_get_cpu_sync(mon, true) -> cpu_synchronize_state(cpu) -> ioctl KVM_GET_LAPIC (taking KVM as example)
... the cpu state is not synchronized when the apic-id is available as argument. The cpu state should be synchronized when apic-id is available. Otherwise the "info lapic <apic-id>" always returns stale data.
