A simple record: today, when debugging the dormant code, we encountered a very strange problem. During the wake-up process, we encountered a problem that we did not see oops. It seems that the operation is illegal, and the CPU enters the abnormal state. Bad mode in prefetch abort handler Detected

Flags: nzcv irqs off fiqs on mode uk8_32 segment user, the code is normal, and there is no rare operation, so there should be no such strange error, the reason is that local_irq_save and local_irq_restore are not paired on a branch path, making the parameter passed to local_irq_restore incorrect. This error occurs because the value of the processor mode bit in CPSR is incorrect.
