6d54aaf389 metronomefb: Fix warning when building 64bit
The metronome driver produces warnings when built on x86-64 as it assumes that
size_t is an int. Use %Zd instead.

93f78da405 Revert "vt: fix background color on line feed"
This reverts commit c9e587abfd, and the
subsequent commits that fixed it up:

 - afa9b649 "fbcon: prevent cursor disappearance after switching to 512
   character font"

 - d850a2fa "vt/fbcon: fix background color on line feed"

 - 7fe3915a "vt/fbcon: update scrl_erase_char after 256/512-glyph font
   switch"

by request of Alan Cox. Quoth Alan:
  "Unfortunately it's wrong and its been causing breakages because
   various apps like ncurses expect our previous (and correct)
   behaviour."

Alexander sent out a similar patch.

aef7db4bd5 fbdev: fix recursive notifier and locking when fbdev console is blanked
Fix infinite recursive notifier in the fbdev layer.  This causes recursive
locking.  Dmitry Baryshkov found the problem and confirmed that the patch
fixes the bug.

After doing
# echo 1 > /sys/class/graphics/fb0/blank

08650869e0 fbcon: fix monochrome color value calculation
Commit 22af89aa0c ("fbcon: replace mono_col
macro with static inline") changed the order of operations for computing
monochrome color values.  This generates 0xffff000f instead of 0x0000000f
for a 4 bit monochrome color, leading to image corruption if it is passed
to cfb_imageblit or other similar functions.  Fix it up.

The driver is based on different source files including corgi_ssp.c,

and many others.

The LCD and Backlight device actually share the same SPI device, so
they are made into this single driver.

3aa04f1b07 atmel_lcdfb: disable LCD and DMA engines when suspending
When suspending the system with atmel_lcdfb enabled, I sometimes see
this:

	atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10

Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.

There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.

Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.

e8a91c953f [ARM] omap: Fix IO_ADDRESS() macros
OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
for use with __raw_{read|write}* for accessing registers.  Therefore,
these macros should return (void __iomem *) cookies, not integer values.

Doing this improves typechecking, and means we can find those places
where, eg, DMA controllers are incorrectly given virtual addresses to
DMA to, or physical addresses are thrown through a virtual to physical
address translation.

Impact: cleanup

Video mode selection became always possible in 2.6.23-rc1 after i386 setup
code rewrite in C.

Regardless, VIDEO_SELECT is stupid config option because it affects only
kernel setup code, not code which always stays in memory.

vga= always possible now which is good.

922613436a [ARM] 5200/1: am200epd: use fb notifiers and gpio api
The original am200epd driver was designed with bad assumptions. It
manipulated GPSR/GPLR registers directly. It relied on direct access to the
pxa LCDC registers which have since conflicted with commit
ce4fb7b892 . This patch moves it into mach-pxa
and overhauls it to use a fb obtained through fb notifiers. It now uses the
generic GPIO api.

relying on this behaviour was incorrect in any case and the BUG also
appeared when the device node was on an ext3 filesystem.

969830b2fe radeonfb: fix accel engine hangs
Some chips appear to have the 2D engine hang during screen redraw,
typically in a sequence of copyarea operations. This appear to be
solved by adding a flush of the engine destination pixel cache
and waiting for the engine to be idle before issuing the accel
operation. The performance impact seems to be fairly small.

Here is a trace on an RV370 (PCI device ID 0x5b64), it records the
RBBM_STATUS register, then the source x/y, destination x/y, and
width/height used for the copy:

----------------------------------------
radeonfb_prim_copyarea: STATUS[00000140] src[210:70] dst[210:60] wh[a0:10]
radeonfb_prim_copyarea: STATUS[00000140] src[2b8:70] dst[2b8:60] wh[88:10]

radeonfb_prim_copyarea: STATUS[80026133] src[e8:80] dst[e8:70] wh[80:10]
radeonfb_prim_copyarea: STATUS[8002612d] src[170:80] dst[170:70] wh[30:10]
radeonfb_prim_copyarea: STATUS[80026127] src[1a8:80] dst[1a8:70] wh[8:10]
radeonfb_prim_copyarea: STATUS[80026121] src[1b8:80] dst[1b8:70] wh[88:10]
radeonfb_prim_copyarea: STATUS[8002611b] src[248:80] dst[248:70] wh[68:10]
----------------------------------------

When things are going fine the copies complete before the next ROP is
even issued, but all of a sudden the 2D unit becomes active (bit 17 in
RBBM_STATUS) and the FIFO retry (bit 13) and FIFO pipeline busy (bit
14) are set as well.  The FIFO begins to backup until it becomes full.

What happens next is the radeon_fifo_wait() times out, and we access
the chip illegally leading to a bus error which usually wedges the
box.  None of this makes it to the console screen, of course :-)
radeon_fifo_wait() should be modified to reset the accelerator when
this timeout happens instead of programming the chip anyways.

Ker:xnel panic - not syncing: Irrecoverable deferred error trap.
----------------------------------------

Another quirk is that these copyarea calls will not happen until the
first drivers/char/vt.c:redraw_screen() occurs.  This will only happen
if you 1) VC switch or 2) run "consolechars" or 3) unblank the screen.

This seems to happen because until a redraw_screen() the screen scrolling
method used by fbcon is not finalized yet.  I've seen this with other fb
drivers too.

So if all you do is boot straight into X you will never see this bug on
the relevant chips.

efc4918143 radeon: misc corrections
I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font.  The problem
goes away if I disable acceleration.

I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.

1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
   and the XORG video driver differ.  I've made the kernel
   match what XORG is using.

2) In radeonfb_engine_reset() we have top-level code structure
   that roughly looks like:

	if (family is 300, 350, or V350)
		do this;
	else
		do that;
	...
	if (family is NOT 300, OR
	    family is NOT 350, OR
	    family is NOT V350)
		do another thing;

   this last conditional makes no sense, is always true,
   and obviously was likely meant to be "family is NOT
   300, 350, or V350".  So I've made the code match the
   intent.

fdac4e69a1 sticore: don't activate unsupported GSC STI cards on HPPA
On HPPA there exists some older GSC graphics cards, which need special
graphic-card-BIOS patching to become supported.  Since we don't have yet
implemented the patching, it's better to detect such cards in advance,
inform to the user that there are known problems and to not activate the
card.

Problematic GSC cards and BIOS versions are:
* Hyperdrive/Hyperbowl (A4071A) graphics card series:
   * ID = 0x2BCB015A (Version 8.04/8)
   * ID = 0x2BCB015A (Version 8.04/11)
* Thunder 1 VISUALIZE 48 card:
   * ID = 0x2F23E5FC (Version 8.05/9)
* Thunder 2 VISUALIZE 48 XP card:
   * ID = 0x2F8D570E (Version 8.05/12)
* Some Hyperion and ThunderHawk GSC cards

5bb49fcd50 video/fb: cleanup FB_MAJOR usage
Currently, linux/major.h defines a GRAPHDEV_MAJOR (29) that nobody uses,
and linux/fb.h defines the real FB_MAJOR (also 29), that only fbmem.c
needs.  Drop GRAPHDEV_MAJOR from major.h, move FB_MAJOR definition from
fb.h to major.h, and fix fbmem.c to use major.h's definition.
