Yep, the license and patent status seem to be separate issues.

However, I am not sure getting a clarification from the author even
helps us legally.  Also, why are we more critical of an Intel-provided
idea than any other idea we get from the community?  The scary answer
is that in many ways they are the same, and have the same risks.

So unless we hear about a problem, I think we should use the code.
