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.

* Scroll Method
*/
/* There are several methods fbcon can use to move text around the screen:
*
* Operation Pan Wrap
*---------------------------------------------
* SCROLL_MOVE copyarea No No
* SCROLL_PAN_MOVE copyarea Yes No
* SCROLL_WRAP_MOVE copyarea No Yes
* SCROLL_REDRAW imageblit No No
* SCROLL_PAN_REDRAW imageblit Yes No
* SCROLL_WRAP_REDRAW imageblit No Yes
*
* (SCROLL_WRAP_REDRAW is not implemented yet)
*
* In general, fbcon will choose the best scrolling
* method based on the rule below:
*
* Pan/Wrap > accel imageblit > accel copyarea >
* soft imageblit > (soft copyarea)
*
* Exception to the rule: Pan + accel copyarea is
* preferred over Pan + accel imageblit.
*
* The above is typical for PCI/AGP cards. Unless
* overridden, fbcon will never use soft copyarea.
*
* If you need to override the above rule, set the
* appropriate flags in fb_info->flags. For example,
* to prefer copyarea over imageblit, set
* FBINFO_READS_FAST.
*
* Other notes:
* + use the hardware engine to move the text
* (hw-accelerated copyarea() and fillrect())
* + use hardware-supported panning on a large virtual screen
* + amifb can not only pan, but also wrap the display by N lines
* (i.e. visible line i = physical line (i+N) % yres).
* + read what's already rendered on the screen and
* write it in a different place (this is cfb_copyarea())
* + re-render the text to the screen
*
* Whether to use wrapping or panning can only be figured out at
* runtime (when we know whether our font height is a multiple
* of the pan/wrap step)
*
