Update of what's left of the previous 25-patch series. Rebased on new 4.16-rc1 amdkfd-next branch. Added ability to use VMs from DRM render node file descriptors as discussed with Christian. In order to keep backwards compatibility with older Thunks without GPUVM support, we still need the ability to create our own VMs as a fallback. The alternative would be checking for !pdd->vm in lots of places, which would be more prone to errors. This patch series requires an updated Thunk because the ioctl numbers shifted since v2. I pushed and update to fxkamd/drm-next-wip on github.com:RadeonOpenCompute/ROCT-Thunk-Interface.git that also uses the new acquire_vm ioctl.
