intelfbhw_get_p1p2 is used only if REGDUMP is defined - compile it in only
if REGDUMP is defined - one less compiler warning.

According to drivers/video/intelfb/intelfb.h, the intelfb driver
supportes the following devices:
830M/845G/852GM/855GM/865G/915G/915GM/945G/945GM. So the description in
drivers/video/Kconfig and the documentation in
Documentation/fb/intelfb.txt is outdated.
airlied: cleaned up some other obvious mistakes in intelfb.txt.

[04/05] intelfb: implement FBIO_WAITFORVSYNC ioctl
The (unofficial) FBIO_WAITFORVSYNC ioctl is implemented by sleeping on the appropriate waitqueue, as defined in my earlier patch. Currently, only display 0 (aka pipe A) is supported.

[03/05] intelfb: Implement basic interrupt handling
Functions have been added to enable and disable interrupts using the MMIO registers. Currently only pipe A vsync interrupts are enabled.
A generalized vsync accounting struct is defined, with the intent that it can encapsulate per-pipe vsync related info in the future. Currently a single instance is hard-coded.
The interrupt service routine currently only looks for vsync interrupts on pipe A, and increments a counter and wakes up anyone waiting on it.
This implementation is heavily influenced by similar implementations in the atyfb and matroxfb drivers.

The backlight changes that went in had a bug where they could cause the
kernel to access an unitialized pointer when blanking if there is no
backlight control on a machine.
The bug affects atyfb, aty128fb, nvidiafb and rivafb. radeonfb seems to
be ok. This fixes it.

I wish I was happier about this patch. It'll serve as a placeholder for
the moment. I'm still trying to get a G550 working in order to even
reproduce the problem this patch introduces. I find that the G450 has
jitter even without this patch, so it won't show me what the patch changed.
At this point, I'll continue trying to get the G550 to work, and in
parallel work with the G450 to work out the kinks.
The patch is below.
Set XDVICLKCTRL only on PPC, as doing this apparently introduces jitter on
the G550, at least on x86 architectures.

There were still some issues with offb when BootX doesn't provide a
proper display node, this fixes them. This also re-instates the
palette hacks that were disabled a couple of kernel versions ago when
I converted to the new OF parsing, and shuffles some functions around
to avoid prototypes.

Since we now use the generic backlight infrastructure, I think we need to
call rivafb_bl_init before calling register_framebuffer since otherwise
rivafb_bl_init might race with the framebuffer layer already opening the
device and setting up the video mode. In this case we might end up with a
not yet fully intialized backlight (info->bl_dev still NULL) when calling
riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel
dies without any further notice during boot.
This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb
would be affected too - I can fix that too but don't have any hardware to
test this on.

CONFIG_FB_NVIDIA already depends on CONFIG_PCI in drivers/video/Kconfig.
Driver does an extra ``sanity check'' which is then redundant.

This patch fixes several problems:
- The legacy backlight value might be set at interrupt time. Introduced
a worker to prevent it from directly calling the backlight code.
- via-pmu allows the backlight to be grabbed, in which case we need to
prevent other kernel code from changing the brightness.
- Don't send PMU requests in via-pmu-backlight when the machine is about
to sleep or waking up.
- More Kconfig fixes.

Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw
too much power when suspended to RAM, reducing drastically the battery
lifetime. The solution is to enable suspend-to-D2 on these machines. They
are whitelisted through their subsystem vendor/device ID. This fixes
http://bugzilla.kernel.org/show_bug.cgi?id=3022
The patch introduces a framework to alter the pm_mode and reinit_func fields
of the radeonfb_info structure based on a whitelist. This should facilitate
future hardware-dependent workarounds. The workaround for the Samsung P35
that is already in the radeonfb code has been rewritten using this framework.
The behavior can be overridden with module options:
i) video=radeonfb:force_sleep=1
enable suspend-to-D2 also on non-whitelisted machines (useful for
testing new notebook models),
ii) video=radeonfb:ignore_devlist=1
Disable checking the whitelist and do not apply any workarounds.

The backlight and lcd subsystems can be notified by the framebuffer layer
of blanking events. However, these subsystems, as a whole, can function
independently from the framebuffer layer. But in order to enable to the
lcd and backlight subsystems, the framebuffer has to be compiled also,
effectively sucking in a huge amount of unneeded code.
To prevent dependency problems, separate out the framebuffer notification
mechanism from the framebuffer layer and permanently link it to the kernel.
