workaround cavium thunderx silicon erratum
Status in linux package in Ubuntu:
Status in linux source package in Xenial:
This impacts 2 socket Cavium ThunderX systems using pass-1.1 silicon, and can result in IO hangs.
$ dmesg | grep "ITS command queue timeout"
The workaround is in gicv3 specific code, and only activated when the hw revision in the IIDR matches ThunderX pass 1.x silicon, so risk to other platforms is minimal.
