This patch adds a new framebuffer driver for the Intel Based macs. This
framebuffer is needed when booting from EFI to get something out the box.

This is a fix for the most annoying problem that remained with neofb:
After "setterm -powersave powerdown" the console blanker will disable the
backlight after the given timeout expires. If this happens after the lid
has been shut, we read "LCD off" from the register and store that in the
driver. Once the lid is opened, the backlight turns on, but any key press
that would awaken the blanked console will switch the backlight off again.
The workaround so far was to use the "display config toggle" Fn key combo -
once if no external display is attached, otherwise as often as required to
restore the desired display setup.
The following patch fixes the issue at least for the LCD-only case, with no
external monitor attached. Other display setup permutations are pending
further testing, but so far I can guarantee at least no negative change in
behaviour, if any at all.

nVidia is churning out chipsets like there's no tomorrow. And even though the
pci_device_id table now has numerous entries, it is still not guaranteed that
all supported devices are included or will be included.
Fortunately, nvidiafb has chipset detection logic built in. So, change the
contents of the pci_device_id table so it will capture all nVidia devices of
the display class. Unsupported chipsets will then be filtered out by
nvidiafb's detection logic.

The EDID block should specify the display's operating limits (vertical and
horizontal sync ranges, and maximum dot clock). If not given by the EDID
block, the ranges are extrapolated from the modelist. However, the
computation used is only a rough approximation, and the resulting values may
not reflect the actual capability of the display. This problem is frequently
encountered when the EDID block has a single entry, the single mode entry will
fail validation.
To prevent this, calculate the values based on the same method used in
fb_validate_mode().

Reported by: Rich (Bugzilla Bug 6417)
"if savage driver is used in x.org together with savagefb, it results in
seriously garbled and distorted screen - coupled with severe slowdowns."
This bug is the result of Xorg unable to handle savagefb altering the
hardware which results in X failing to start properly and/or failed console
switching.
Add savagefb_state_save and savagefb_state_restore. These hooks will only
save and restore the extended VGA registers. Standard VGA registers will be
left alone. This is enough to make savagefb play nicely with the latest
Xorg savage driver, and perhaps with savage DRI. (Transient screen artifacts
may appear before X loads and during console switches).
(Unfortunately, blanking the screen also leaves Xorg in a blanked state, so I
have to unblank the screen before Xorg loads. So I doubt if the transient
screen artifacts will be completely invisible but hopefully it will only be
for a shorter duration (not much).)

Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
VM_SHM.
remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since
it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not
place pages on the LRU. The pages are therefore never subject to swap
anyways. Remove all the vm_flags settings before calling remap_pfn_range.
After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense
to do this to vga_vram_base, because we're going to access memory between
vga_vram_base and vga_vram_end.
But it doesn't really make sense to map starting at vga_vram_end, because
we aren't going to access memory starting there. On ia64, which always has
to be different, ioremapping vga_vram_end gives you something completely
incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being
nonsense.
As a bonus, we often know the size up front, so we can use ioremap()
correctly, rather than giving it a zero size.

the physical monitor. This patch fixes that problem on the systems I have
easy access to...
I've tested with SLES9SP3 (2.6.5+ kernel) and 2.6.16-rc6 custom kernels on
an IBM eServer p5 520 w/G450 (a.k.a GXT135P on IBM's ppc64 systems), and a
colleague of mine (Ian Romanick) tested it successfully on an Apple ppc32
box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to
verify that it didn't obviously break anything. In my testing, I covered
single-card, single and dual-head setups using both HD15 and DVI-D signals,
on both the IA32 and ppc64 boxes. While everything appeared fine on both
boxes, I did encounter one problem: I can't get any signal on the DVI-D
output on the ppc64 box. However, this is also the case without my patch.
I just noticed that screen-blanking only occurs on the primary display as
well.

Bugzilla Bug 6299:
A pixel size of 8 bits produces wrong logo colors in x86_64.
The driver has 2 methods for setting the color map, using the protected
mode interface provided by the video BIOS and directly writing to the VGA
registers. The former is not supported in x86_64 and the latter is enabled
only in i386.
Fix by enabling the latter method in x86_64 only if supported by the BIOS.
If both methods are unsupported, change the visual of vesafb to
STATIC_PSEUDOCOLOR.

The monochrome->color expansion routine that handles bitmaps which have
(widths % 8) != 0 (slow_imageblit) produces corrupt characters in big-endian.
This is caused by a bogus bit test in slow_imageblit().
Fix.
This patch may deserve to go to the stable tree. The code has already been
well tested in little-endian machines. It's only in big-endian where there is
uncertainty and Herbert confirmed that this is the correct way to go.
It should not introduce regressions.

Fixes for the pxafb driver:
* Return -EINVAL for resolutions that are too large as per framebuffer
driver policy.
* Increase the error timeout for disabling the LCD controller. The current
timeout is sometimes too short on the Sharp Zaurus Cxx00 hardware and an
extra delay in an error path shouldn't pose any problems.
* Fix a dev reference which causes a compile error when DEBUG is defined.

Generalise the Corgi backlight driver by moving the default intensity and
limit mask settings into the platform specific data structure. This enables
the driver to support other Zaurus hardware, specifically the SL-6000x (Tosa)
model.
Also change the spinlock to a mutex (the spinlock is overkill).

Updates to the HP Jornada 680 Backlight driver:
- Correct the suspend/resume functions so the driver compiles
(SUSPEND_POWER_DOWN/RESUME_POWER_ON no longer exist).
- Convert the driver to match the recent platform device changes.
- Replace the unsafe static struct platform_device with dynamic allocation.
- Convert the driver to the new backlight code.
This has not been tested on a device due to lack of hardware but wouldn't
compile beforehand.

Backlight class attributes are currently easy to implement incorrectly.
Moving certain handling into the backlight core prevents this whilst at the
same time makes the drivers simpler and consistent. The following changes are
included:
The brightness attribute only sets and reads the brightness variable in the
backlight_properties structure.
The power attribute only sets and reads the power variable in the
backlight_properties structure.
Any framebuffer blanking events change a variable fb_blank in the
backlight_properties structure.
The backlight driver has only two functions to implement. One function is
called when any of the above properties change (to update the backlight
brightness), the second is called to return the current backlight brightness
value. A new attribute "actual_brightness" is added to return this brightness
as determined by the driver having combined all the above factors (and any
driver/device specific factors).
Additionally, the backlight core takes care of checking the maximum brightness
is not exceeded and of turning off the backlight before device removal.
The corgi backlight driver is updated to reflect these changes.
