MIPS: die() does not call die notifier chain
The MIPS implementation of die() forgets to call notify_die() and thus notifiers registered via register_die_notifier() are not called. This results in kgdb not being activated on exceptions. The only subtlety is that notify_die declares its regs argument w/o const, so the const had to be removed from mips die() as well.
