77d6750470 V4L/DVB (5632): Dvb-pll: pass dvb_frontend_parameters to generic set() function
Rename dvb_pll_desc.setbw() to set(), and accept struct dvb_frontend_parameters
instead of passing both freq and bandwidth, so that this may be used as a
generic function.

In order to do this, dvb_pll_configure must also be altered in the same manner,
to take struct dvb_frontend_parameters instead of freq and bandwidth.

ecf854df72 V4L/DVB (5629): Cx88: VP3054 support can't be a module when cx88 is compiled in
If cx88 support is compiled into the kernel while vp3054 is left as a module,
the kernel will fail to link.  Adjust the existing "#if" code in cx88 so
that it won't consider vp3054 to be supported in this case.

It might make sense to move vp3054 selection into the "customisation" menu
instead of a cx88 sub-option (though this is a cx88 feature, there is no extra
chip involved).

It might also make sense to use dvb_attach() to load vp3054 support.

8314418629 Freezer: make kernel threads nonfreezable by default
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.

f057131fb6 V4L/DVB (5816): Cx88-blackbird: fix vidioc_g_tuner never ending list of tuners
v4l-info and other programs would loop indefinitely while querying the
tuners for cx88-blackbird cards.

The cause was that vidioc_g_tuner didn't return an error value for
qctrl->id != 0, making the application think there is a never ending
list of tuners...

This patch adds the same index check as done in vidioc_g_tuner() in
cx88-video.

6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
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:

arch/alpha/kernel/err_common.c

6bdcc6e6db V4L/DVB (5363): Dvb: Remove lgh06xf driver
The code of the dvb-pll driver and the lgh06xf driver is nearly
identical.  The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call.  The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it.  By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.

There is one other difference.  dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this.  In some devices the PLL is not reachable over I2C at the timer the
tuner is attached.  Some more initialization, such as firmware loading,
must take place first.  None of the devices using a LG-H06xF should have
this problem.

05ad390724 V4L/DVB (5166): Remove obsolete alias defines of CONFIG_* settings
The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly.  To work around
this, makefiles would define some new macro based on the setting of a
config variable.  e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary.  This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.

95efa03bd6 V4L/DVB (5012a): Remove some unused code from kernel mainstream
There are some long time unused code under some media driver source files. 
There's no need of keeping it at mainstream.
Those unused code will remain available at V4L/DVB master tree and also at
kernel history.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

fa027c2a0a [PATCH] mark struct file_operations const 4
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

a96afb3e94 V4L/DVB (5021): Cx88xx: Fix lockup on suspend
Suspending with the cx88xx module loaded causes the system to lock up
because the cx88_audio_thread kthread was missing a try_to_freeze()
call, which caused it to go into a tight loop and result in softlockup
when suspending. Fix that.

reference to .init.text: from .text between 'cx88_card_setup'
(at offset 0x68c) and 'cx88_risc_field'
Caused by leadtek_eeprom() being declared __devinit and called from
a non-devinit context.

315eb962d2 V4L/DVB (4980): Fixes bug 7267: PAL/60 is not working
On cx88 driver, sampling rate should be at chroma subcarrier freq (FSC).
However, driver were programming wrong values for PAL/60, PAL/Nc and
NTSC 4.43. This patch do the proper calculation. It also calculates
htotal, hdelay and hactive constants, according with the sampling
rate.
It is tested with PAL/60 by Piotr Maksymuk and Olivier. Also tested with
the already-supported standards.

Test is still required for PAL/Nc.
