For both patches:

Reviewed-by: Lucas De Marchi <lucas.demarchi at intel.com>

I'm actually expecting these to be "squashed" in the original patch,
i.e. that we will have a rebase removing them from the branch. If that
is not the case, then you need a much better explanation in the commit
itself rather than on the cover letter.
