Rebased on the public drm-next-4.15-wip. Patch 8 from the WIP patch series did not apply at all, because upstream KFD doesn't support GPUVM yet. The "lib: Closed hash table ..." change is updated and the same as what I sent to LKML yesterday. Changes are mainly in the way the self test is hooked up, Kconfig options and some checkpatch fixes. If it takes too long to get accepted upstream, I could add it under drivers/gpu/drm/amd/chash in the interim. This is only compile tested on this branch. I can't do much more because the upstream KFD doesn't support Vega10 and GPUVM yet. Someone will have to add PASID support for graphics on top of this.
