[Nouveau] [PATCH drm-misc-next v4 1/8] drm/gpuvm: rename struct drm_gpuva_manager to struct drm_gpuvm
Rename struct drm_gpuva_manager to struct drm_gpuvm including
corresponding functions. This way the GPUVA manager's structures align
very well with the documentation of VM_BIND [1] and VM_BIND locking [2].
It also provides a better foundation for the naming of data structures
and functions introduced for implementing a common dma-resv per GPU-VM
including tracking of external and evicted objects in subsequent
patches.
