 GEM objects can now have a function table instead of having the callbacks on the
 DRM driver struct. This is now the preferred way and drivers can be moved over.
 
+DRM_GEM_CMA_VMAP_DRIVER_OPS, DRM_GEM_SHMEM_DRIVER_OPS already support this, but
+DRM_GEM_VRAM_DRIVER_PRIME does not yet and needs to be aligned with the previous
+two. We also need a 2nd version of the CMA define that doesn't require the

+ * FIXME: Locking
+ *
+ * - fbcon state itself is protected by the console_lock, and the code does a
+ *   pretty good job at making sure that lock is held everywhere it's needed.
+ *
+ * - access to the registered_fb array is entirely unprotected. This should use
+ *   proper object lifetime handling, i.e. get/put_fb_info. This also means
+ *   switching from indices to proper pointers for fb_info everywhere.
+ *
+ * - fbcon doesn't bother with fb_lock/unlock at all. This is buggy, since it
+ *   means concurrent access to the same fbdev from both fbcon and userspace
+ *   will blow up. To fix this all fbcon calls from fbmem.c need to be moved out
+ *   of fb_lock/unlock protected sections, since otherwise we'll recurse and
+ *   deadlock eventually. Aside: Due to these deadlock issues the fbdev code in
+ *   fbmem.c cannot use locking asserts, and there's lots of callers which get
+ *   the rules wrong, e.g. fbsysfs.c entirely missed fb_lock/unlock calls too.
