Bug Description

The 2-socket variation of Cavium ThunderX boards requires NUMA support.

NUMA support is required to support the 2-socket variation of Cavium
ThunderX boards. These patches have not yet been accepted upstream.
However, as far as I can tell, all outstanding feedback has been
addressed and no additional changes have been requested since the last
iteration (v15). I'll follow that progress and resubmit should that
change.

I've regression tested on an X-Gene system and on a dragonboard 410c.
For the dragonboard, I disabled the new configs (as I'd expect that's
how they'd land in that branch).
