I have expected that license was copied correctly in the past from gnu.org,
when same differences are in various projects. I just point out on another change.

Thank You for tip about web.archive.org - I really don't know about that web

Thank You for reponse.

Everyone can do that. I believe that someone report it already or at least
constult it. I write about this here because I should do that. When You
know about this difference in license in kernel, I believe that they know
it too and they decide it is ok.
