Rebased on adeucher/amd-staging-4.13 and tested on Vega10 (graphics) and Kaveri (KFD). Meaningful graphics tests with retry faults enabled will only be possible after PASID support is added to amdgpu_cs. The chash table was moved to drivers/gpu/drm/amd/lib for now but is ready to move to lib if needed. I have not got any feedback on LKLM and I don't want that to hold up the patch series.
