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.
