Oh, Steven is right.  The ones which are removed by the above patch
are different ones.  That said, it might be a good idea to apply fixes
for them to -stable too.  Mathieu, are you interested in submitting
similar -stable fixes for kernel/module.c::percpu_modcopy() and
lockdep.c::static_obj()?

Thanks.
