is the first bad commit commit 2de50e9674fc4ca3c6174b04477f69eb26b4ee31 Author: Russell Currey Date: Mon Feb 8 15:08:20 2016 +1100 powerpc/powernv: Remove support for p5ioc2 "p5ioc2 is used by approximately 2 machines in the world, and has never ever been a supported configuration." The code for p5ioc2 is essentially unused and complicates what is already a very complicated codebase. Its removal is essentially a "free win" in the effort to simplify the powernv PCI code. In addition, support for p5ioc2 has been dropped from skiboot. There's no reason to keep it around in the kernel.
