consistent Currently the vcpu_make_request and signal_event in vcpu_lock_instr_emulation does not check whether target VCPU is up and running. This can cause problems because when VCPU is created but not launched, vcpu_make_request will not trigger wait_event on target VCPU, but signal_event may still execute to reduce the counter. This patch adds a check before vcpu_make_request and signal_event to make sure the request and signal are issued after target VCPU is up.
