kernel-sync:
Original patch description from the patch by Rafael J. Wysocki <rjw@sisk.pl>:
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.

If v4l2_ctrl_next is called without the V4L2_CTRL_FLAG_NEXT_CTRL then
it should check whether the passed control ID is valid and return 0
if it isn't. Otherwise a for-loop over the control IDs will never
end.

This patch adds an internal ioctl-like interface which can be used in
situations where a single Video4Linux device is implemented by multiple
device drivers. One master device controls one or more slave devices.
The slaves provide Video4Linux ioctl-like interface for the use of the
master.
Only a handful of ioctls are implemented at the moment. More can (and
should) be added as more functionality is required.

The VBI DMA is handled in a special way and is marked with a bit.
However, that bit was set at the wrong time and could be cleared
by mistake if a PCM (or other) DMA request would arrive before the
VBI DMA was completed. So on completion of the VBI DMA the driver
no longer knew that that DMA transfer was for VBI data. And this
in turn caused havoc with the card's DMA engine.

v4l_printk_ioctl_arg() is a debug printing function that is normally

elsewhere. This patch gets it in a state where it will work correctly,

Due to several internal API changes on kernel, kernel backward
compatibility were lost. Basically, compat.h should be the last include
for it to work properly.
This patch basically reorders kernel headers to allow backward compat to
work fine.
Also:
Some includes were added after some non-include macros, on old drivers.
Better to keep all includes at the beginning of the files.

From: Trent Piepho <xyzzy@speakeasy.org>
If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as
the first user after the driver is loaded, the driver wedges itself and will
never capture properly. Even if one uses a V4L2 application later, it still
won't work.
If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2
driver, then the driver will be ok. One can then run a V4L1 application, and
it will work.
It turns out the problem is with norm changing and the crop support that was
added in 2.6.21. The driver defaults to PAL, and keeps the last norm it was
set too across opens. If one changes the norm via V4L1, the cropping
parameters are not reset like they should be, and they'll remain broken across
device opens.
This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl
VIDIOCSCHAN handler. The norm is set via the existing call to set_input(),
which calls set_tvnorm(), which will reset the cropping values now that it is
able to detect the norm change.

For svhs, tuner, and tuner_type, be consistent in using UNSET instead of -1.
For tuner_type also consistently use the existing constants:
0 => TUNER_TEMIC_PAL
1 => TUNER_PHILIPS_PAL_I
2 => TUNER_PHILIPS_NTSC
4 => TUNER_ABSENT
5 => TUNER_PHILIPS_PAL
21 => TUNER_TEMIC_4039FR5_NTSC
25 => TUNER_LG_PAL_I_FM

The bttv driver has code to detect if a tda9887 is present, that was previous
used to auto-load the tda9887 driver. Now there is no tda9887 driver, so the
code is pointless; it just figures out if it should load the driver and then
does nothing.
For cards that are defined as having no tuner, the init code would still do
i2c probes for various tuner devices and auto-load the tuner module. That can
be skipped for cards that don't need it. The code is made to understand that
in addition to 'UNSET', 'TUNER_ABSENT' also means no tuner.
The tuner into printk()s are also made nicer. Levels are added, INFO or
WARNING, depending on the meaning. For cards with no tuner, or no tuner
defined, a more informative message is printed.
Card has no tuner, before patch:
bttv0: tuner type=-1
or
bttv0: tuner type=4
After patch:
bttv0: tuner absent
Card has a tuner, but the type isn't defined, before patch:
bttv0: tuner type=-1
After patch:
bttv0: tuner type unset [<- also warning now, as the tuner won't work right]
