Yes, I am almost doing nothing on this work these days but there was a little bit of progress thanks to so much advices; I succeeded in back porting recent version of SMACK on kernel 3.4 which my board is currently supporting.

Some parameters may be controlled and arranged but other parts, especially device drivers, should be touched from the clear and new state; If I do porting by modifying a built image, it would be more difficult to dealing with these issues.
