[PULL][Xenial] Workaround Cavium ThunderX erratum 23144

[Dann Frazier]

This addresses LP: #1589704. It is a fix on top of the arm64 numa
support which landed upstream for 4.7, and which we backported to
xenial. That code won't be present in yakkety until it graduates to
4.7 - at which point I'll double-check that this CONFIG is enabled
there as well.

The following changes since commit 4843b9787adda03c376b5e271af3187a16a7950b:

  clocksource: Allow unregistering the watchdog (2016-06-06 14:09:16 -0700)
