[PATCH v3 0/3] vm- and vma cleanups

[Thomas Hellström]

The first patch of the series addresses a vm open count bug by
removing the vm open count.

The second patch removes the vma refcount that is no longer needed;
the vma is kept a live by taking the vm refcount and object lock.

Finally the last patch removes some unnecessary code. There should be
no functional changes.

v3:
- Documentation fixes
- Added R-Bs

Thomas Hellström (3):
  drm/i915: Remove the vm open count
  drm/i915: Remove the vma refcount
  drm/i915/gem: Remove some unnecessary code
