Subject: [PATCH drm-misc-next 0/5] PowerVR VM fixes

Hi,

Some major GPUVM changes landed just before v8 of the PowerVR series. Since v8
went in rather quickly (review process was finished otherwise) I haven't had the
chance to review the subsequent code changes.

Hence, this series with a few fixes in this context. Plus a minor GPUVM patch to
make the drm_gpuvm_prepare_* helpers useful for PowerVR.

- Danilo

  drm/imagination: vm: prevent duplicate drm_gpuvm_bo instances
  drm/imagination: vm: check for drm_gpuvm_range_valid()
  drm/imagination: vm: fix drm_gpuvm reference count
  drm/gpuvm: fall back to drm_exec_lock_obj()
  drm/imagination: vm: make use of GPUVM's drm_exec helper
