This made it into next as 83ac4ca943affce56a2c408ddb2f5232f478fb11 and
ba63053f018721a0ad60b083e21a15e324a4a8c4. Is it right that it is there
twice? And in the Author line the - in my name is missing. Would be
great if that could be fixed up.

Something like:

git filter-branch -f --env-filter 'test "$GIT_AUTHOR_NAME" != "Uwe Kleine König" || GIT_AUTHOR_NAME="Uwe Kleine-König"' linus/master..

should do the trick.
