The first patch is new because it'a a cleanup that does not require any change to the module verification code. The second patch is the only one that is intended to change any functionality. The rest only deduplicates code but I did not receive any review on that part so I don't know if it's desirable as implemented. The first two patches can be applied separately without the rest.
