This series is intended to add support for shutting down the GPU on kernel shutdown/reboot using the ->shutdown() hook, similar to what amdgpu does. This is mainly intended to workaround a bios issue on the P50 that was preventing nouveau from initializing the dedicated GM107 GPU on that system properly. You can find more details on this issue in the patch labeled "Shut down GPU on kernel
