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).

The following changes since commit e53f19d6cccd1304606144bf079bb2ec5854df27:

  ipv4: only create late gso-skb if skb is already set up with
CHECKSUM_PARTIAL (2016-03-17 06:23:09 -0600)
