-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:
-
-- lots of code in fbcon.c
-
-- a bunch of the hooks in fbcon_ops, maybe the remaining hooks could be called
- 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
-
-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.

+ On modern machines, on mainstream machines (like x86-64) or when
