Why are you dropping those authorship data?

Ok, it is clear to me that most of the code there got rewritten, and,
while IANAL, I think they still have some copyrights on it.

So, if you're willing to do that, you need to get authors ack
on such patch.

Same note applies here: we need Wind River's ack on that to drop it.
