The patch series looks good to me.  I note that you went ahead and backported
patches for the current release candidate kernel.  I had held off on them (as noted
in my original patch series cover letter) because the kernel wasn't released yet and I
was unsure of policy on that.  As it stands I don't think any of the patches for
the unreleased kernel will actually be used yet unless someone is building against a
4.13-rc* kernel.  I suppose that can happen but even then they would have to update
acinclude.m4 to allow compile against a 4.13 kernel.

In any case, going forward I'll go ahead and backport patches even though the kernel
they are targeted for has not been released yet.

Thank you Joe!
