Building with CONFIG_DEBUG_SECTION_MISMATCH=y reports:
CC drivers/video/pvr2fb.o
LD drivers/video/built-in.o
WARNING: drivers/video/built-in.o(.text+0xb9b0): Section mismatch in reference from the function pvr2fb_check_var() to the variable .devinit.data:pvr2_fix
The function pvr2fb_check_var() references
the variable __devinitdata pvr2_fix.
This is often because pvr2fb_check_var lacks a __devinitdata
annotation or the annotation of pvr2_fix is wrong.
This is obviously crap as no such reference exists, but it's a bit
closer to reality from older versions which blamed the PCI table. The
real problem was a reference to pvr2_var.vmode from pvr2fb_check_var(),
as pvr2_var is flagged as __devinitdata (pvr2_fix is also, so at least
that part is right).
pvr2_var.vmode is just a fancy way of saying FB_VMODE_NONINTERLACED, so
we just reference that explicitly instead.

During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.
But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.
For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.
These changes are necessary to fix a hibernation regression related
to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

The current attr_fgcol_ec / attr_bgcol_ec macros do a simple shift of bits
to get the color from vc_video_erase_char. For a monochrome display
however the attribute does not contain any color, only attribute bits.
Furthermore the reverse bit is lost because it is shifted out, the
resulting color is always 0.
This can bee seen on a monochrome console either directly or by setting it
to inverse mode via "setterm -inversescreen on" . Text is written with
correct color, fb_fillrects from a bit_clear / bit_clear_margins will get

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.
This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.
Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.

Avoid displaying garbage on unused framebuffers. For most users a single
framebuffer is used together with fbcon. sm501fb supports two framebuffers
where one often is assigned to fbcon and the other one is left unused during
the boot.
The problem here is that framebuffers not in use by fbcon happen to display
garbage. This can easily be solved by making sure that framebuffer memory and
palette ram are cleared.
The problem can be observed by using looking at the panel output (fb1) after
booting the kernel with fbcon on crt (fb0). This is the default
configuration. It's also possible to watch the garbage on the crt framebuffer
by passing "fbcon=map:1" on the kernel cmdline. This will assign fbcon to the
panel (fb1) and leave the crt (fb0) unused.

This patch makes it possible to control panel pins usage with flags passed
from the platform data. Without this patch the sm501fb driver always controls
the VBIASEN and FPEN pins. The polarity and use of these pins are very
platform specific, so this patch introduces the flags
SM501FB_FLAG_PANEL_USE_VBIASEN and SM501FB_FLAG_PANEL_USE_FPEN which enable
the use of these pins.
This patch is needed to support the a Sharp LQ104V1DG21 lcd panel on SuperH
platforms such as R2D-1 and R2D-PLUS boards. Letting the sm501fb driver
control the FPEN and VBIASEN pins like today just results in lcd panel

The current nvidiafb_check_var() simply bails out if the selected mode is
out of range of the panel dimensions. A good question would be why the
bogus mode is being selected in the first place -- the panel dimensions
that are read back are certainly bogus, but alas, I have no idea where to
even begin looking at the i2c/EDID/DDC mess:
nvidiafb: Device ID: 10de0165
nvidiafb: CRTC0 analog not found
nvidiafb: CRTC1 analog not found
nvidiafb: EDID found from BUS1
nvidiafb: CRTC 0 is currently programmed for DFP
nvidiafb: Using DFP on CRTC 0
nvidiafb: Panel size is 1280 x 1024
nvidiafb: Panel is TMDS
nvidiafb: unable to setup MTRR
nvidiafb: Flat panel dithering disabled
nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000)
In my .config I presently have:
CONFIG_FIRMWARE_EDID=y
CONFIG_FB_DDC=y
CONFIG_FB_NVIDIA_I2C=y
I've not tried fiddling with these options, as I haven't the vaguest idea
what I should be looking at.
As a workaround, simply groveling for a new mode based on the probed
dimensions seems to work ok. While it would be nice to debug this further
and sort out why the panel information is bogus, I think it's still worth
retrying the mode based on the panel information at hand as a last-ditch
effort, rather than simply bailing out completely.

Since the introduction of the acquire_console_sem calls in
0333d83509, kexecing can cause the
kernel to deadlock:
ps3fb_shutdown()
-> unregister_framebuffer()
-> fb_notifier_call_chain(FB_EVENT_FB_UNBIND)
-> fbcon_fb_unbind()
-> unbind_con_driver()
-> bind_con_driver()
[ acquires console_sem ]
-> fbcon_deinit()
-> fbops->fb_release(newinfo, 0)
-> ps3fb_release()
-> ps3fb_sync()
[ acquires console_sem ]
This change avoids the deadlock by moving the acquire_console_sem()
out of ps3fb_sync(), and puts it into the two other callsites, leaving
ps3fb_release() to call ps3fb_sync() without the console semaphore.
[Geert]
- Corrected call sequence above
- ps3fb_release() may be called with and without console_sem held. This is an
inconsistency that should be fixed at the fb level, but for now, try to
acquire console_sem in ps3fb_release().
I think it's safer to let ps3fb_release() try to acquire console_sem and
not refresh the screen if it fails, than to call ps3fb_sync() without
holding console_sem, as ps3fb_par may be modified at the same time, causing
crashes or lockups.
Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen
when display flipping is disabled, which is an uncommon case (except during
shutdown/kexec).

This patch adds Graphics Output Protocol support to the kernel. UEFI2.0 spec
deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output
Protocol (GOP) is produced. Therefore, the boot loader needs to query the
UEFI firmware with appropriate Output Protocol and pass the video information
to the kernel. As a result of GOP protocol, an EFI framebuffer driver is
needed for displaying console messages. The patch adds a EFI framebuffer
driver. The EFI frame buffer driver in this patch is based on the Intel Mac
framebuffer driver.
The ELILO bootloader takes care of passing the video information as
appropriate for EFI firmware.
The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI
platform.

This patch adds an additional loop, that delays turning off the DMA
until the LCDC core has been turned off. This prevents the picture
to be shifted some random length when the kernel re-initializes
the LCDC.
Without this patch, the LCDC keeps running for some small time after the
PWRCON:LCD_PWR has been cleared ; the FIFO suffers an underrun and on
re-starting the LCDC the FIFO data stays shifted.
This behavior has been seen and fixed on AT91SAM9261-EK and two custom
AT91SAM9261 boards, all of them having different LCD panels.

The code in fb_ddc_read() is said to be based on the implementation of the
radeon driver:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fc5891c8a3ba284f13994d7bc1f1bfa8283982de
However, comparing the old radeon driver code with the new fb_ddc code
reveals some differences. Most notably, the I2C bus lines are held at the
end of the function, while the original code was releasing them (as the
comment above correctly says.)
There are a few other differences, which appear to be responsible for read
failures on my system. While tracing low-level I2C code in i2c-algo-bit, I
noticed that the initial attempt to read the EDID always failed. It takes
one retry for the read to succeed. As we are about to remove this
automatic retry property from i2c-algo-bit, reading the EDID would really
fail.
As a summary, the I2C lines quirk which is supposedly needed to read EDID
on some older monitors is currently breaking the (first) read on all other
monitors (and might not even work with older ones - did anyone try since
October 2006?)
After applying the patch below, which makes the code in fb_ddc_read()
really similar to what the radeon driver used to have, the first EDID read
succeeds again.
On top of that, as it appears that this code has been broken for one year
now and nobody seems to have complained, I'm curious if it makes sense to
keep this quirk in place. It makes the code more complex and slower just
for the sake of monitors which I guess nobody uses anymore. Can't we just
get rid of it?

cpu_data is currently an array defined using NR_CPUS. This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.
These changes were adopted from the sparc64 (and ia64) code. An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index. This corresponds to the index into a cpumask_t as well as the
per_cpu index. It's used in various places like show_cpuinfo().
cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.

There is a test in tgafb_mono_imageblit() for a colour image with a fall-back

The pixel mask calculation in tgafb_mono_imageblit() uses a variable
left-shift on a 32-bit data type by up to 32. Shifting by the width of a data
type or more produces an unpredictable result according to the C standard.
Rather than widening the data type this fix makes sure the count is between 0
and 31. The reason is not to penalise 32-bit platforms with operation on a
"long long" type for a marginal case that is meant not to happen (blitting an
image of a zero width).
The reason it has escaped for so long is the Alpha, being purely 64-bit, :-)
does not mask the shift out to 32 bits. This is a valid implementation --
producing the correct result certainly falls within "unpredictable behaviour".
It does trigger on MIPS though and it is the recent merge of the TC support
which only enabled the driver for use on anything other than the Alpha. For
MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as
it should be and the frame buffer is not updated.

As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular
cursor can still be seen blinking in the upper left part of the screen. It is
fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE,
KD_TEXT) call done by something in userspace, perhaps by X itself, while the
tty is still in graphics mode. And when the tty is in KD_TEXT mode, the
cursor timer is restarted.
Although this is a userspace problem, we can work around it by delaying the
restart of the cursor timer until an fbcon_switch() is called. In other
words, the cursor timer will not be restarted even if a KD_TEXT mode switch is
requested.

ps3fb: Enhance horizontal panning on firmware 1.90 and up:
- On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying
rectangles from XDR to DDR memory with different source and destination
line lengths. Hence larger horizontal virtual resolutions can be supported
(up to 16368 pixels).
- As the actual frame buffer memory layout no longer matches the entries in
ps3fb_res[], create fake struct ps3fb_ioctl_res data for the
PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it
keep on working.

of the GPU command buffer and the frame buffer. Fix and cleanup various issues
with overlap and alignment:
- Move the GPU command buffer from the beginning to the end of video memory
- Exclude the GPU command buffer from the actual frame buffer memory
- Align the start of the virtual frame buffer to PAGE_SIZE instead of to 64
KiB, and don't waste memory if it's already aligned (for fullscreen modes)
- Take into account the alignment when checking memory requirements and
maximum number of frames
- Make sure fb_fix_screeninfo.smem_start always points to the virtual frame
buffer start, so we don't have to compensate for that in ps3fb_mmap()

The i.MX frame-buffer read operation should be faster for all configurations
then drawing each individual character again in response to scroll events.
The nonstandard fields allows to configure frame-buffer special options flags
for different display configurations by board specific initialization code.
One of such specific options is reversed order of pixels in each individual
byte. i.MX frame-buffer seems to be designed for big-endian use first. The
byte order is correctly configured for little-endian ordering, but if 1, 2 or
4 bits per pixel are used, pixels ordering is incompatible to Linux generic
frame-buffer drawing functions.
The patch "Allow generic BitBLT functions to work with swapped pixel order in
bytes" introduces required functionality into FBDEV core. The pixels ordering
selection has to be enabled at compile time CONFIG_FB_CFB_REV_PIXELS_IN_BYTE
and for each display configuration which requires it by flag
FB_NONSTD_REV_PIX_IN_B in "nonstd" field of info structure.
This patch provides way for board specific code to select this option.

Various console drivers are able to resize the screen via the con_resize()
hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware. However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.
To work around this problem, add an extra parameter to con_resize(). This
parameter is ignored by drivers except for vgacon. If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success. If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware. The
latter is the more correct behavior.
With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.

There are a few nvidia hardware where the i2c port assignments are reversed,
i.e., the 1st i2c port is assigned to the secondary display and the 2nd i2c
port to the primary display. In most cases, if only 1 display is attached, or
if only 1 flatpanel and 1 analog display is attached, the port reversal is of
no consequence. However if 2 flatpanels are attached, it can cause display
problems.
There is no sane way of determining if the hardware reversed the i2c port
assignment, so the simplest fix is to add a boot/module option, "reverse_i2c
to explicitly reverse the i2c port.
This also restores i2c ordering back to the pre-2.6.22 state.

This patch adds support for the other three palette formats possible with
the PXA LCD controller. This is required on boards where an LCD is connected
with all its 18 bits. With this patch, it's possible to use an 8-bit mode
with 18-bit palette entries. This used to be possible in 2.4 kernels but
disappeared in 2.6. With current kernels, you can only get wrong colours
out of an LCD connected this way.
Users can choose the palette format by doing something like this
in their board definition:
static struct pxafb_mach_info my_fb_info = {
[...]

uvesafb is an enhanced version of vesafb. It uses a userspace helper (v86d)
to execute calls to the x86 Video BIOS functions. The driver is not limited
to any specific arch and whether it works on a given arch or not depends on
that arch being supported by the userspace daemon. It has been tested on
x86_32 and x86_64.
A single BIOS call is represented by an instance of the uvesafb_ktask
structure. This structure contains a buffer, a completion struct and a
uvesafb_task substructure, containing the values of the x86 registers, a flags
field and a field indicating the length of the buffer. Whenever a BIOS call
is made in the driver, uvesafb_exec() builds a message using the uvesafb_task
substructure and the contents of the buffer. This message is then assigned a
random ack number and sent to the userspace daemon using the connector
interface.
The message's sequence number is used as an index for the uvfb_tasks array,
which provides a mapping from the messages coming from userspace to the
in-kernel uvesafb_ktask structs.
The userspace daemon performs the requested operation and sends a reply in the
form of a uvesafb_task struct and, optionally, a buffer. The seq and ack
numbers in the reply should be exactly the same as those in the request.
Each message from userspace is processed by uvesafb_cn_callback() and after
passing a few sanity checks leads to the completion of a BIOS call request.

After fixing the too small memory allocation in cr_backlight_probe()
from drivers/video/backlight/cr_bllcd.c
(commit e3bbb3f053) I noticed that the
Coverity checker also thought there were a few memory leaks in there.
I took a closer look and confirmed that there were indeed several
leaks.
At the start of the function we allocate storage for a
'struct cr_panel' and store the pointer in a variable named 'crp'.
Then we call pci_get_device() and pci_read_config_byte() and if
either of them fail we return without freeing the memory allocated
for the 'struct cr_panel'. These two leaks are easy to fix since we
don't even use 'crp' for anything up to this point, so I simply
moved the allocation further down in the function so it only happens
just before we actually need it.
A bit further down we call backlight_device_register() and store the
result in 'crp->cr_backlight_device'. In case of error we return
'crp->cr_backlight_device' from the function, thus leaking 'crp'
itself. The same thing happens with the call to lcd_device_register().
To fix these two leaks I declare two new pointers to hold the return
values, so that in case of error we can return the pointer (as before)
but without leaking 'crp'.
This version of the patch also adds missing
backlight_device_unregister() / lcd_device_unregister() / pci_dev_put()
calls to error paths.

Three main sets of changes:
1) dmi_get_system_info() return value should have been marked const,
since callers should not be changing that data.
2) const-ify DMI internals, since DMI firmware tables should,
whenever possible, be marked const to ensure we never ever write to
that data area.
3) const-ify DMI API, to enable marking tables const where possible
in low-level drivers.
And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.
The bulk of the changes are #2 and #3, which are interrelated. #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

This builds upon my previous attempts to resolve some jitter problems seen
with the Matrox G450 and G550 -based cards, including odd disparities observed
between x86 and Power -based machines in a somewhat less hackish way (removing
the hacked ifdefs).
Apparently, preference should be given to use the DVI PLL when frequencies
permit, the Standard PLL otherwise. The max pixel clock for the panellink
interface is extracted from the PInS information on the card and used as a
limit to determine which PLL to use.

Visualize-EG, Graffiti and A4450A graphics cards on PARISC can
be configured in double-buffer and standard mode, but the stifb
driver supports standard mode only.
This patch detects double-buffered cards more reliable.
It is a real bugfix for a very nasty problem for all parisc users which have
wrongly configured their graphic card. The problem: The stifb graphics driver
will not detect that the card is wrongly configured and then nevertheless just
enables the graphics mode, which it shouldn't. In the end, the user will see
no further updates / boot messages on the screen.
We had documented this problem already on our FAQ
(http://parisc-linux.org/faq/index.html#viseg "Why do I get corrupted graphics

All of these drivers use a silly:
struct all_info {
struct fb_info info;
struct foo_par par;
};
struct all_info *all = kzalloc(sizeof(*all), GFP_KERNEL);
all->info.par = &all->par;
etc. etc. code sequence, basically replicating the provided
framebuffer_alloc()/framebuffer_release(), and doing it badly.
Not only is this massive code duplication, it also caused a
bug in that we weren't setting the fb_info->device pointer
which results in an OOPS when fb_is_primary_device() runs.
Fix all of this by using framebuffer_{alloc,release}() and
passing in "&of_device->dev" as the device pointer.

Fixes STN LCD support for the atmel_lcdfb framebuffer driver.
This patch is the result of a work from Jan Altenberg and has
been tested on a Hitachi SP06Q002 on at91sam9261ek.
It adds a Kconfig switch that enables the proper LCD in the
board configuration file (STN or TFT). The switch is used
in arch/arm/mach-at91/at91sam9261_devices.c & board-sam9261ek.c
as an example.
This patch includes the "Fix wrong line_length calculation"
little one from Jan and Haavard (submitted earlier).

The current scheme works on static interpretation of text names, which
is wrong.
The output-device setting, for example, must be resolved via an alias
or similar to a full path name to the console device.
Paths also contain an optional set of 'options', which starts with a
colon at the end of the path. The option area is used to specify
which of two serial ports ('a' or 'b') the path refers to when a
device node drives multiple ports. 'a' is assumed if the option
specification is missing.
This was caught by the UltraSPARC-T1 simulator. The 'output-device'
property was set to 'ttya' and we didn't pick upon the fact that this
is an OBP alias set to '/virtual-devices/console'. Instead we saw it
as the first serial console device, instead of the hypervisor console.
The infrastructure is now there to take advantage of this to resolve
the console correctly even in multi-head situations in fbcon too.

To emphasize the existence of the SPEs (which can be used under Linux), we
added a second row of (smaller) helper penguin logos, one for each SPE.

The SH board that was the only user for this code was removed entirely from
the kernel quite some time ago, so there's no reason to leave the stubs in
place. Additionally this driver was completely broken anyways, so there's
not really a lot of point in fixing it up either.
I can't imagine that this driver gets any testing on ARM either, given that
FB_BLANK_UNBLANKING doesn't exist, and kills the build regardless of which
platform is compiling. This fixes that, too.
It wouldn't be a lot of work to finish the platform device conversion and
go with a generic 8-bit read/write_reg and kill off the architecture
dependence completely, should someone have any use for this driver.

This allows for proper console unregistration via the VT layer, and updates
the FB layer to use it. This makes debugging new console drivers much easier,
since you can properly clean them up before unloading.
[adaplas]
unregister_framebuffer() is typically called as part of the driver's
module_exit(). Doing so otherwise will freeze the machine as the VT layer is
holding reference counts on fbcon, and fbcon on the driver. With this change,
it allows unregister_framebuffer() to be called safely anywhere as needed.
Additions from the original: If multiple drivers are used by fbcon, and if
one of them unregisters, a driver will take over the consoles vacated by the
outgoing one (via set_con2fb_map). Once only the outgoing driver remains,
then fbcon will unbind from the VT layer (if CONFIG_HW_CONSOLE_UNBINDING is
set to y).
It is important that these drivers implement fb_open() and fb_release()
just to ensure that no other process is using the driver. Likewise, these
drivers _must_ check the return value of unregister_framebuffer().

set_con2fb_map() has regressed for some time. Using fbcon=map:01, for
example, works only if there is only 1 working framebuffer. Trying to do a
set_con2fb_map() on a non-allocated vc will freeze the system.
- ensure that succeeding drivers after the first gets mapped to the console
- remove fbcon_preset_display() and modify fbcon_set_display() to include the
former's functionality

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.

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

Well, first of all, I don't want to change so many files either.
What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.
In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(
Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)
Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.
Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

I can query the status of output device0 by running " cat
/sys/class/video_output/acpi_video0
" The return value is defined in ACPI SPEC B.5.5 _DCS(Return the
Status of Output Device). Also you can turn off video1 and turn on
video0 by " echo 0 > acpi_video1; echo 0x80000000 > acpi_video0".
Please reference ACPI SPEC B.5.7 _DSS for the parameter definition.
Please note that it may or may NOT works purely depending on if
your vendor providing correct ACPI video extension support in bios.

Reported by James Pearson as:
boot to run level 3
if not root, then make sure /dev/console is writeable
login and type:
setterm -blank 0
start X
type into an xterm:
while true; do echo "" > /dev/console; usleep 100000; done
while the above loop is running switch to the text console and back
again (Ctrl-Alt-F1 then Ctrl-Alt-F7)
... and the screen will be shifting (and wrapping) to the left.
This problem stems from continuously writing text to the system console (which
is in KD_TEXT mode) while the foreground console is in KD_GRAPHICS
mode. Somewhere along the way, console printing got confused and omitted the
KD_GRAPHICS/KD_TEXT test. Thus, vgacon attempted to scroll the screen of X,
which causes X to shift.
Fix by disallowing vgacon to touch the hardware when the vc is in KD_GRAPHICS
mode. A definitive fix entails a full audit of the console code.

Check if the mode can properly display the screen. This will be needed by
drivers where the capability is not constant with each mode. The function
fb_set_var() will query fbcon the requirement, then it will query the driver
(via a new hook fb_get_caps()) its capability. If the driver's capability
cannot handle fbcon's requirement, then fb_set_var() will fail.
For example, if a particular driver supports 2 modes where:
mode1 = can only display 8x16 bitmaps
mode2 = can display any bitmap
then if current mode = mode2 and current font = 12x22
fbset <mode1> /* mode1 cannot handle 12x22 */

where the framebuffer is allocated from system RAM (via vmalloc). Using
__raw_read/__raw_write (fb_readl/fb_writel) for these drivers is
illegal, especially in other platforms.
Create file read and write methods for these types of drivers. These are
named fb_sys_read() and fb_sys_write().

It was always intended for the logo to be drawn only if both fbcon and the
driver that is mapped to it are both compiled statically. Currently, if fbcon
is loaded prior to the driver, the logo is not shown. Reverse the order, and
the code may attempt to draw the logo which is __initdata. By accident, this
bug is rarely seen because this method of loading the modules is not common
and secondly, a code in fb_prepare_logo() that checks the height of the logo
(now a random value) rarely succeeds.
Fix by drawing the logo only if both fbcon and the driver are statically
compiled.

I have a problem with blanking. The soundcard uses speakers of the monitor.
Sound is muted when the screen blanks due to a bug in aty128fb.c.
Here is a fragment of linux/fb.h
/* VESA Blanking Levels */
#define VESA_NO_BLANKING 0
#define VESA_VSYNC_SUSPEND 1
#define VESA_HSYNC_SUSPEND 2
#define VESA_POWERDOWN 3
enum {
/* screen: unblanked, hsync: on, vsync: on */
FB_BLANK_UNBLANK = VESA_NO_BLANKING,
/* screen: blanked, hsync: on, vsync: on */
FB_BLANK_NORMAL = VESA_NO_BLANKING + 1,
/* screen: blanked, hsync: on, vsync: off */
FB_BLANK_VSYNC_SUSPEND = VESA_VSYNC_SUSPEND + 1,
/* screen: blanked, hsync: off, vsync: on */
FB_BLANK_HSYNC_SUSPEND = VESA_HSYNC_SUSPEND + 1,
/* screen: blanked, hsync: off, vsync: off */
FB_BLANK_POWERDOWN = VESA_POWERDOWN + 1
};
So FB_BLANK_NORMAL is 1, FB_BLANK_VSYNC_SUSPEND is 2,
FB_BLANK_HSYNC_SUSPEND is 3, FB_BLANK_POWERDOWN is 4.
And now:
blank = FB_BLANK_NORMAL (1)
blank & FB_BLANK_HSYNC_SUSPEND (1 & 3) is true,
so normal blank caused hsync suspend and sound is muted.

I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.
Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:
[PATCH] scatterlist.h needs types.h

This shrinks the size of "struct i2c_client" by 40 bytes:
- Substantially shrinks the string used to identify the chip type
- The "flags" don't need to be so big
- Removes some internal padding
It also adds kerneldoc for that struct, explaining how "name" is really a
chip type identifier; it's otherwise potentially confusing.
Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name
and for i2c_adapter.name, this needed to affect i2c_adapter too. The
adapters which used that symbol now use the more-obviously-correct
idiom of taking the size of that field.
JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to
avoid wasting space in padding.
