Hi Dave, Daniel,
Ideally this would have gone through drm-misc, but it had dependencies on some changes in the DC code which were in my latest PR, so I sent this as a separate PR on top of my amdgpu PR.
The following changes since commit 0f899fd466b693a129b16994c1b2b4db2fcde4a4:
drm/amdkfd: Improve kfd_process lookup in kfd_ioctl (2020-01-09 16:08:19 -0500)
