Arjan's copy_from_user validation code already does verification checks on the copies using gcc magic. Some of the others might be useful - kmalloc_from_user() is a fairly obvious interface, a copy_from_user_into() interface where you pass the destination object and its actual length as well is mostly covered by Arjan's stuff.
