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.

Before kernel 2.6.14, the driver checked for status before stopping the
thread. So, a compatibility test did exist. After 2.6.14, the
if (state)
were replaced by:
if (1)
However, it makes no sense to keep the if(1).

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: Oleg Nesterov <oleg@tv-sign.ru>
Spotted and tested by Thomas Sattler <tsattler@gmx.de>.
cinergyT2.c does cancel_delayed_work() + flush_scheduled_work() while
holding cinergyt2->sem. This leads to deadlock because work->func()
needs the same mutex to complete. Another bug is that this code in fact
can't reliably stop the re-arming delayed_work.
Convert this code to use cancel_rearming_delayed_work() and move it
out of ->sem. Another mutex, ->wq_sem, was added to protect against the
concurrent open/resume.
This patch is a horrible hack to fix the lockup which happens in practice.
As Dmitry Torokhov pointed out this driver has other problems and needs
further changes.
