Hi all,
Today's linux-next merge of the drm tree got conflicts in several amdgpu files because there are a set of (mostly identical) patches that appear Linus' tree and the drm tree. In each case I just used the version fo the file from the drm tree.
You should do a test merge between your tree and Linus' tree and see what you want to do about the resolution (either do the back merge (I think with v4.16-rc6), or provide Linus with branch that has the merge done). Its a bit of a mess :-(
