you can only get new features included upstream in the latest Linux kernel. So earliest version would be 3.4. You have to maintain you own repository for earlier version. But backporting should be not so much trouble if you have it included upstream.

you can do this in between.

        cd linux
        git config --global user.name "陈俊杰 (Aaron Chen)"
        git config --global user.email aaron.chen at siliconmotion.com

Aaron, Git is nowadays documented pretty well. So just use

    git help command

(like `git help commit`) to read the manual. Additionally you can just search for it using your favorite search engine. Interesting reads should be [1][2][3].
