Garbage collect fbdev scrolling acceleration
--------------------------------------------
-Scroll acceleration is disabled in fbcon by hard-wiring p->scrollmode =
-SCROLL_REDRAW. There's a ton of code this will allow us to remove:
+Scroll acceleration has been disabled in fbcon. Now it works as the old
+SCROLL_REDRAW mode. A ton of code was removed in fbcon.c and the hook bmove was
+removed from fbcon_ops.
+Remaining tasks:
-- lots of code in fbcon.c
-
-- a bunch of the hooks in fbcon_ops, maybe the remaining hooks could be called
+- a bunch of the hooks in fbcon_ops could be removed or simplified by calling
directly instead of the function table (with a switch on p->rotate)
- fb_copyarea is unused after this, and can be deleted from all drivers
+- after that, fb_copyarea can be deleted from fb_ops in include/linux/fb.h as
+ well as cfb_copyarea
+
Note that not all acceleration code can be deleted, since clearing and cursor
support is still accelerated, which might be good candidates for further
deletion projects.
