Use CPUs on the close NUMA when setting the EQ affinity hints.

Dan, are we sure there are no down-sides for always doing this? this
code is probably there for many years and we're introducing here new
behaviour to potentially to many Ms installs when they get distro
update that includes this patch.

I don't see a downside, this just favors using the node local CPUs before others.

OK, so this just favors before others and not limits (not in front of
the code now)? would be good to improve the change log and make this
clear.

I don't understand your 2nd sentence there.  "Ms installs"?

Millions of installs that run Linux driver.
