Hello,

This is resend of the KEXEC_SIG patchset.

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.

Do you have the link of your 1st version?

This is the previous version:
https://lore.kernel.org/lkml/cover.1635948742.git.msuchanek@suse.de/ (local)

Thanks

Michal

And after going through the whole series, it doesn't tell what this
patch series intends to do in cover-letter or patch log.

Thanks
Baoquan

The first two patches can be applied separately without the rest.

Thanks

Michal
