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
GPUVM provides common infrastructure to track external and evicted GEM
objects as well as locking and validation helpers.
Especially external and evicted object tracking is a huge improvement
compared to the current brute force approach of iterating all mappings
in order to lock and validate the
Currently the DRM GPUVM offers common infrastructure to track GPU VA
allocations and mappings, generically connect GPU VA mappings to their
backing buffers and perform more complex mapping operations on the GPU VA
space.
However, there are more design patterns commonly used by drivers, which

This patch adds an abstraction layer between the drm_gpuva mappings of
a particular drm_gem_object and this GEM object itself. The abstraction
represents a combination of a drm_gem_object and drm_gpuvm. The
drm_gem_object holds a list of drm_gpuvm_bo structures (the structure
representing this
Introduce flags for struct drm_gpuvm, this required by subsequent
commits.

Provide a common dma-resv for GEM objects not being used outside of this
GPU-VM. This is used in a subsequent patch to generalize dma-resv,
external and evicted object handling and GEM validation.
