r3396 is alleged to have broken reverse of arcadia. it is alleged to have fixed fifa 2010. r3396 contains a change to thumb ASR which is plainly wrong. after that time several other cpu fixes were made, and the ASR changes are not necessary to fix fifa 2010 anymore. so I am reverting that part, and reverse of arcadia should be retested.
