89c223a616 macfb: Do not overflow fb_fix_screeninfo.id
Don't overflow the 16-character fb_fix_screeninfo id string (fixes some 
console erasing and blanking artifacts). Have the ID default to "Unknown" 
on machines with no built-in video and no nubus devices. Check for 
fb_alloc_cmap failure.

bca404afdc fbdev: fix FB console blanking
The commit aef7db4bd5 fixed the problem with
recursive locking in fb blanking code if blank is caused by user setting
the /sys/class/graphics/fb*/blank.  However this broke the fbcon timeout
blanking.

If you use a driver that defines ->fb_blank operation and at the same time
that driver relies on other driver (e.g.  backlight or lcd class) to blank
the screen, when the fbcon times out and tries to blank the fb, it will
call only fb driver blanker and won't notify the other driver.  Thus FB
output is disabled, but the screen isn't blanked.

Restore fbcon blanking and at the same time apply the proper fix for the
above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are
already called through notification from fb_blank, thus we don't have to
blank the fb again.

c4c6fa9891 radeonfb: fix problem with color expansion & alignment
The engine on some radeon variants locks up if color expansion is called
for non aligned source data.  This patch enables a feature of the core
fbdev to request aligned input pixmaps and uses the HW clipping engine to
clip the output to the requested size

Since the compiler optimizes memset(x,0,n) to __memzero() perfectly

7953031da4 ARM: OMAP: Remove broken LCD driver for SX1
Recently the omap McBSP code was cleaned up to get rid of
direct McBSP register tinkering by the drivers. Looks like
lcd_sx1.c never got converted, and now it breaks builds.

It seems the lcd_sx1.c driver is attempting SPI mode, but
doing it in a different way compared to omap_mcbsp_set_spi_mode().

Remove the broken driver, patches welcome to add it back when
done properly by patching both mcbsp.c and lcd_sx1.c.

b3b4dc8840 lcd: fix oops if driver only interested in .set_power
The LCD driver core calls LCD drivers when either the blanking state or
the display mode has changed, but does not make any check to see if the
called driver has a .set_mode method.

This means if a driver only has a .set_power method then the system will
OOPS on changing mode (and with the console semaphore held so you cannot
easily see the problem).

Fix the problem by ensuring that either callback is valid before use.

a684e7d330 fbdev: fix fb_compat_ioctl() deadlocks
commit 3e680aae4e ("fb: convert
lock/unlock_kernel() into local fb mutex") introduced several deadlocks
in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion,
unlike lock_kernel().  This broke frame buffer applications on 64-bit
systems with a 32-bit userland.

commit 120a37470c ("framebuffer compat_ioctl
deadlock") fixed one of the deadlocks.

This patch fixes the remaining deadlocks:
  - Revert commit 120a37470c,
  - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(),
  - Change all callsites of fb_ioctl() where info->lock is already held to
    call do_fb_ioctl() instead,
  - Add sparse annotations to all routines that take info->lock.

Fix deadlock in fb_compat_ioctl.  fb_compat_ioctl acquires a mutex and

Updatescrollmode is marked inline, but it's big and is called only from

This unbreaks the legacy configs in {corgi,spitz}_defconfig, however, SPI
based ADS7846 touchscreen driver and a new SPI-based corgi_lcd.c driver
with integrated backlight support are recommended.

0d468300dc Remove empty imacfb.c file
Commit 7c08c9ae0c ("efifb/imacfb
consolidation + hardware support") claimed to remove imacfb entirely and
merge its DMI table into the efifb driver.  So far so good, but the diff
actually ended up just generating an empty file instead of removing it.

[ Technical reason: the patch header looked like

  diff -puN drivers/video/imacfb.c~efifb-imacfb-consolidation-hardware-support drivers/video/imacfb.c
  --- a/drivers/video/imacfb.c~efifb-imacfb-consolidation-hardware-support
  +++ a/drivers/video/imacfb.c
  @@ -1,376 +0,0 @@

  which git will think is a truncation, not a delete.  Git wants to see a
  target of /dev/null to consider it a delete. ]

So remove it properly.

The function alloc_carmine_fb() references the variable __devinitdata

4d31a2b74c fbdev: ignore VESA modes if framebuffer does not support them
Currently, it is possible to set a graphics VESA mode at boot time via the
vga= parameter even when no framebuffer driver supporting this is
configured.  This could lead to the system booting with a black screen,
without a usable console.

Fix this problem by only allowing to set graphics modes at boot time if a
supporting framebuffer driver is configured.

9350cc90ca uvesafb: don't treat mode info retrieval failures as errors
Some BIOSes return error codes when queried for information about
modes from their own modelist.  uvesafb treats this as an error
case and bails out.

Change this behavior so that broken modes do not prevent the driver
from working.  Only the failure to retrieve information about any
usable video mode is considered to be an error case.

b1ee26bab1 radeonfb: accelerate imageblit and other improvements
Implement support for HW color expansion of 1bpp images, along with some
improvements to the FIFO handling and other accel operations.

The offset fixup code is now unnecessary as the fbcon core will call our
set_par upon switch back from KD_GRAPHICS before anything else happens.  I
removed it as it would slow down accel operations.

The fifo wait has been improved to avoid hitting the HW register as often,
and the various accel ops are now performing better caching of register
values.

Overall, this improve accel performances.  The imageblit acceleration does
result in a small overall regression in performances on some machines (on
the order of 5% on some x86), probably becaus the SW path provides a
better bus utilisation, but I decided to ingnore that as the performances
is still very good, and on the other hand, some machines such as some
sparc64 get a 3 fold performance improvement.

486ff387c0 cirrusfb: do not change MCLK for Alpine chips
A memory clock value (MCLK) is changed to a minimum required by a current
mode bandwidth.  This usually lowers the MCLK to its minimum (50 MHz) thus
decreasing the card performance.  Just leave the MCLK value set by card
BIOS.

The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a
pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a
jitter on the screen.  A countermeasure is to use the MCLK as pixclock
source instead of a VCLK.  The patch implements this as well.

3f7a26b4b9 intelfb: support 945GME (as used in ASUS Eee 901)
Add support for Intel's 945GME graphics chip to the intelfb driver.  I
have assumed that the 945GME is identical to the already-supported 945GM
apart from its PCI IDs; this is based on a quick look at the X driver for
these chips which seems to treat them identically.

The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
I'd be able to use it to get a console at the native 1024x600 resolution
which is not known to the BIOS.  I realised too late that the intelfb
driver does not support mode changing on laptops, so it won't be any
use for me.
