This is a patch that we need to have on Zesty, including on the 16.04.3 installer. On POWER9 the ERAT may be incorrect on wakeup from some stop states that lose state. This causes random segvs and illegal instructions when these stop states are enabled. This patch invalidates the ERAT on wakeup on POWER9 to prevent this from causing a problem.
