[PATCH 00/14] Add KFD GPUVM support for dGPUs v3

[Felix Kuehling]

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.
