To make trigger-after-execute behavior, kernel emulates the
instruction. If the instruction is 'load something into non-
volatile register', exception handler should restore emulated

instruction. If the instruction is 'load something into non-
volatile register', exception handler should restore emulated
register state while returning back, otherwise
