So you admit the patch shouldn't have been accepted.

You just admitted that it was the wrong approach, since it touched arch files it didn't need to, etc.
Which vendor or distro included AA's 2004 patch, since you now claim it is "the right approach"? If you've got a (working) link to a vendor commit, from a long time ago, you will begin to have a better argument.

You've previously claimed that Linus and the other kernel developers are "not qualified" to make judgements about security patches "due to lack of expertise".
