Though seemingly well-ACK'd upstream before the v4.11 merge window,
these patches were pushed off until v4.12 for logistical reasons:
They are required to support new arm64 server systems.

Should this version be merged into the Ubuntu kernel, I'll keep an eye
on any changes that happen before they get merged and backport if

Tested on HiSilicon D05 & QDF2400 platforms, regression tested on a
Cavium ThunderX system in DTB mode.
