In uClinux-coldfire, does ISR begin with SAVE_ALL (entry.s) ? if so, i have a question : How does it restore its interrupt level while ISR is running? Because in SAVE_ALL, the first instruction, move #0x2700,%sr; /* disable intrs */ has changed the current SR, that is , current interrupt level has been losted.
