Notice that this uncovers an issue with the kernel-doc handling of array arguments, causing the first parameter of drm_clflush_pages() to not show up in the rst-generated page. A proposed fix is under review in linux-doc: <http://www.spinics.net/lists/linux-doc/msg42544.html> Changes since v1: - Add section to drm-mm.rst. - Fix kernel-doc style issues. - s/memory/kernel memory/.
