Funky, funky.

I'm assuming it's the

                                page = get_arg_page(bprm, pos, 1);
                                if (!page) {
                                        ret = -E2BIG;
                                        goto out;
                                }

in copy_strings() that causes this. Or possibly, the version in
copy_string_kernel().

Does *this* get that "pr_warn()" printout (and a stack trace once,
just for good measure)?
