Ok, fair enough, I was hoping that "modern" systems would have better
NUMA memory interconnects.  I guess that isn't the case still :(

Things will keep improving, I'm sure.

Mathias, did you have anything you need reworked with this patch or any specific
comments on the overall patch?


If there's a performance benefit in adding these then I'm all for it.
for ring related allocations it makes sense.

Not sure if if there's any benefit in allocating the scratchpad structures from
a closer node, or any harm? xhci driver doesn't really access scratchpad that frequently.

The port related structures are changing completely, so xhci->usb2_ports xhci->usb3_ports
and other related are going away. Just sent a series for that. So some rebasing is needed.
