pthread_cancel may block forever ## Summary In smp when cpu0 calls up_cpu_resume to release the cpu1 lock, another locked cpu1 did not execute immediately, and soon cpu0 called up_cpu_resume again, now cpu1 unable to respond to the interrupt at this time, resulting in a deadlock. Our solution is to restore cpu1 execution from asynchronous to synchronous to ensure that cpu1 is restored. ## Impact none ## Testing ostest -- This is an automated message from the Apache Git Service.
