The drivers for Cavium's ThunderX platforms have hit linux-next. This backports them to Xenial. I tested on a ThunderX system and an X-Gene (for regression). I've also tested on a Dragonboard 410c. For that test, I applied these patches to the 4.4.0-1009.9 release, but left them disabled in the config. The patches required some minor tweaking to apply in Kconfig/Makefile/MAINTAINERS because the dragonboard branch is also carrying a new PCI driver. This changeset includes a refactoring of the pci-generic driver to permit code reuse. pci-generic is currently ARM-specific, and I'm not aware of any system that Ubuntu currently supports that uses it. However, I am aware that a refactoring may complicate the application stable backports. I'll volunteer to resolve any such porting problems.
