by Christian König

Well that's quite a patch set. First of all can you separate this a bit more by driver? I'm assuming we maintainers are supposed to pick that up and apply it. radeon and amdgpu can stick together since that is mostly Alex and me, but I'm not sure if we want to do some of the suggested changes to radeon. Going to pick up the single TTM change for upstreaming. Thanks, Christian.
