commit a6d9b5a2c343dc3cc3daa42f9ddffac2e4130bff
Author: Danilo Krummrich <dakr at redhat.com>

    drm/nouveau: make use of the GPUVM's shared dma-resv
    
    DRM GEM objects private to a single GPUVM can use a shared dma-resv.
    Make use of the shared dma-resv of GPUVM rather than a driver specific
    one.
    
    The shared dma-resv originates from a "root" GEM object serving as
    container for the dma-resv to make it compatible with drm_exec.
    
    In order to make sure the object proving the shared dma-resv can't be
    freed up before the objects making use of it, let every such GEM object
    take a reference on it.
