I had already done this.

Please read this thread:
http://patchwork.ozlabs.org/patch/307941/

All boards I am touching in this patch are surely unmaintained.
(So we cannot ask the reason why they added multiple entries.)

I tried to contact to their maintainers but all mails have been bouncing.

So I dropped Cc: tag when I posted v4.
Otherwise, I would get delivery failure notification mails
from STMP again and again.
