Well, for the concrete patch I posted it is necessary since we do *not*
want random kernel stack garbage to leak anywhere.
I thinkt there has been some misunderstanding. The padding we talk
about is explicit padding (structure member tf_pad), not the implicit one
done by the compiler if the members are not properly aligned.
