The lapic_shutdown() function which is called in sys_reboot path\nwill not disarm the flying timer, it just masks LVTT. lapic_shutdown() clears\nAPIC state w/ LVT_MASKED and timer-mode bit is 0, this can trigger timer-mode\nswitch between tsc-deadline and oneshot/periodic, which can result in preemption\ntimer be cancelled in apic_update_lvtt(). However, We can't depend on this when\nnot exposing tsc-deadline mode and oneshot/periodic modes emulated by preemption\ntimer. Qemu will synchronise states around reset, let's cancel preemption timer\nunder KVM_SET_LAPIC."
