Thomas Zimmermann abbc4d6ecd drm/vram-helper: Reuse existing page mappings in vmap ... For performance, BO page mappings can stay in place even if the map counter has returned to 0. In these cases, the existing page mapping has to be reused by the next vmap operation. Otherwise a new mapping would be installed and the old mapping's pages leak. Fix the issue by reusing existing page mappings for vmap operations.
