Thomas Hellstrom	d7a67cb162	drm/ttm: Use private locks for the default bo range manager ... Searching for a free block in the range manager may in some situations be a lenghty operation, and we want to avoid holding the global lru lock during that time. Instead use a per-manager spinlock. This leaves the global lru lock for quick lru list and swap list manipulation only, including list manipulation associated with reserving buffer objects.
