Hi Huang,

I've run the following script:

|#!/bin/bash
|check_error()
|{
|        r=$?
|        if [ ! $r -eq 0 ]
|        then
|                exit 1
|        fi
|}
|
|modprobe tcrypt mode=200
|modprobe tcrypt mode=200
|dmesg -c > step-0.txt
|
|for ((i=1; i<=7; i++))
|do
|        quilt push step${i}.patch
|        check_error
|
|        make
|        check_error
|
|        rmmod aes_x86_64
|        check_error
|
|        insmod arch/x86/crypto/aes-x86_64.ko
|        check_error
|
|        modprobe tcrypt mode=200
|        modprobe tcrypt mode=200
|        dmesg -c > step-${i}.txt
|done

and the result is attached.
