01dd2fbf0d typo fixes
Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.

Because this is a consolidation of a couple old missed patches, it touches both
Kconfigs and documentation texts.

afd1db1632 fbcon: Revise primary device selection
Use set_con2fb_map() to select the primary display driver instead of using
unbind_con_driver() and bind_con_driver().  Using the former is much simpler

623e71b035 fbcon: allow fbcon to use the primary display driver
Allow fbcon to select the primary display adapter using the
fb_is_primary_device() arch-specific helper.  If a a primary adapter is
detected, fbcon will unbind the old adapter from the VT layer, then rebind
using the new adapter.  This requires that bind_/unbind_con_driver() be made
public.

Because this feature may produce unexpected behavior (from the user's POV),
this must be explicitly enabled in Kconfig.

15bdab959c [PATCH] vgacon: Add support for soft scrollback
The scrollback buffer of the VGA console is located in VGA RAM.  This RAM
is fixed in size and is very small.  To make the scrollback buffer larger,
it must be placed instead in System RAM.

This patch adds this feature.  The feature and the size of the buffer are
made as a kernel config option.  Besides consuming kernel memory, this
feature will slow down the console by approximately 20%.

e4fc27618b [PATCH] fbcon: Console Rotation - Prepare fbcon for console rotation
This patch series implements generic code to rotate the console at 90, 180,
and 270 degrees. The implementation is completely done in the framebuffer
console level, thus no changes to the framebuffer layer or to the drivers
are needed.

Console rotation is required by some Sharp-based devices where the natural
orientation of the display is not at 0 degrees. Also, users that have
displays that can pivot will benefit by having a console in portrait mode
if they so desire.

The choice to implement the code in the console layer rather than in the
framebuffer layer is due to the following reasons:

- it's fast
- it does not require driver changes
- it can coexist with devices that can rotate the display at the hardware level
- it complements graphics applications that can do display rotation

The changes to core fbcon are minimal-- recognition of the console
rotation angle so it can swap directions, origins and axes (xres vs yres,
xpanstep vs ypanstep, xoffset vs yoffset, etc) and storage of the rotation
angle per display. The bulk of the code that does the actual drawing to the
screen are placed in separate files. Each angle of rotation has separate
methods (bmove, clear, putcs, cursor, update_start which is derived from
update_var, and clear_margins).  To mimimize processing time, the fontdata
are pre-rotated at each console switch (only if the font or the angle has
changed).

The option can be compiled out (CONFIG_FRAMEBUFFER_CONSOLE_ROTATION = n) if
rotation is not needed.

Choosing the rotation angle can be done in several ways:

1. boot option fbcon=rotate:n, where
     n = 0 - normal
     n = 1 - 90 degrees (clockwise)
     n = 2 - 180 degrees (upside down)
     n = 3 - 270 degrees (counterclockwise)

2. echo n > /sys/class/graphics/fb[num]/con_rotate

     where n is the same as described above. It sets the angle of rotation
of the current console

3 echo n > /sys/class/graphics/fb[num]/con_rotate_all

     where n is the same as described above. Globally sets the angle of
rotation.

GOTCHAS:

	The option, especially at angles of 90 and 270 degrees, will exercise
the least used code of drivers.  Namely, at these angles, panning is done
in the x-axis, so it can reveal bugs in the driver if xpanstep is set
incorrectly. A workaround is to set xpanstep = 0.

	Secondly, at these angles, the framebuffer memory access can be
unaligned if (fontheight * bpp) % 32 ~= 0 which can reveal bugs in the drivers
imageblit, fillrect and copyarea functions.  (I think cfbfillrect may have
this buglet). A workaround is to use a standard 8x16 font.

Speed:

	The scrolling speed difference between 0 and 180 degrees is minimal,
somewhere areound 1-2%.  At 90 or 270 degress, speed drops down to a vicinity
of 30-40%. This is understandable because the blit direction is across the
framebuffer "direction." Scrolling will be helped at these angles if xpanstep
is not equal to zero, use of 8x16 fonts, and setting xres_virtual >= xres * 2.

Note: The code is tested on little-endian only, so I don't know if it will
work in big-endian. Please let me know, it will take only less than a minute
of your time.

This patch prepares fbcon for console rotation and contains the following
changes:

- add rotate field in struct fbcon_ops to keep fbcon's current rotation
  angle

- add con_rotate field in struct display to store per-display rotation angle

- create a private copy of the current var to fbcon.  This will prevent
  fbcon from directly manipulating info->var, especially the fields xoffset,
  yoffset and vmode.

- add ability to swap pertinent axes (xres, yres; xpanstep, ypanstep; etc)
  depending on the rotation angle

- change global update_var() (function that sets the screen start address)
  as an fbcon method update_start.  This is required because the axes, start
  offset, and/or direction can be reversed depending on the rotation angle.

- add fbcon method rotate_font() which will rotate each character bitmap to
  the correct angle of rotation.

- add fbcon boot option 'rotate' to select the angle of rotation at bootime.
   Currently does nothing until all patches are applied.

998e6d5116 [PATCH] fbcon: Add rl (Roman Large) font
I converted the "rl" console font from the kbd utility to be a built-in font
for the framebuffer console, and I was wondering if you would be OK with
including it.  I've generated a font_rl.c file and related minor
modifications.  I find it's the most visually appealing of the kbd fonts which
is why I use it and selected it for conversion.  I believe the font is GPL'd.

1bbb4f2035 [PATCH] USB: sisusb[vga] update
here is a new and extended version of the sisusbvga (previously: sisusb)
driver. The patch is against 2.6.13 and updates the driver to version 0.0.8.

Additions include complete VGA/EGA text console support and a build-in
display mode infrastructure for userland applications that don't know
 about the graphics internals.

Fixes include some BE/LE issues and a get/put_dev bug in the previous
version.

Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.

Please note that the patch also affects the Makefile in
drivers/video/console as the driver requires the VGA 8x16 font in case
the text console part is selected.

Heavily tested, as usual. Please apply.

One thing though: I already prepared for removal of the "mode" field and
the changed "name" field in the usb_class_driver structure. This will
perhaps need some refinement depending on whether you/Linus merge the
respective core changes before or after 2.6.14.

303b86d991 [PATCH] New framebuffer fonts + updated 12x22 font available
Improve the fonts for use with the framebuffer.

I've added all the characters marked 'FIXME' in the sun12x22 font and
created a 10x18 font (based on the sun12x22 font) and a 7x14 font (based
on the vga8x16 font).

This patch is non-intrusive, no options are enabled by default so most
users won't notice a thing.

I am placing my changes under the GPL, however, I've not seen any copyright
notices on the sun12x22 font and the vga8x16 font which I derived my new
fonts from so I don't know what the copyright status is.

3.2GB when imported into git - space that would just make the early
