Subject: Re: [PATCH 0/1] [RFC] x86: Export information about hardware memory encryption to sysfs

Hello Martin,

Thanks for your contribution.

Your emails contain a footer that threatens with legal repercussions
if their contents are treated in a certain way. This usually means
that, even if some people may comment on the code, there is no way we
can legally merge it, given that these restrictions are incompatible
with the GPL

So please find a way to resend these emails without the footers. I'll
be happy to look into more detail once you do that.
