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.

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.

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.

Clean up the use of structure templates in cx88-i2c and cx88-vp3054-i2c.
For one thing, a real template is supposed to be read-only. And in some
cases it's more efficient to initialize the few fields we need
individually.
This clean-up shrinks cx88-i2c.o by 33% and cx88-vp3054-i2c.o by 49%
(x86_64).

Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence
and a sleep sequence.
The init sequence sets the AGC control register to 0xa0, selecting the fast
time constant and 112 dBuV take-over point. This the recommended value for
DVB-T operation.
The sleep sequence sets bit P4 (which is believed to turn the analog
demodulator on), turns off the tuning voltage, and sets the AGC control
register to 0x60 (external AGC voltage, the recommended value for analog
operation).
The existing dvb-pll users in the cx88 driver, listed below, will gain these
init and sleep sequences.
CX88_BOARD_HAUPPAUGE_HVR1100 Hauppauge WinTV-HVR1100 DVB-T/Hybrid
CX88_BOARD_HAUPPAUGE_HVR1100LP Hauppauge WinTV-HVR1100 DVB-T/Hybrid (Low Profi

CX88_BOARD_HAUPPAUGE_HVR3000 Hauppauge WinTV-HVR3000 TriMode Analog/DVB-S/DV
CX88_BOARD_HAUPPAUGE_HVR1300 Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encod
This non-dvb-pll user in the cx88 driver should only gain the sleep sequence,
as it already had an equivalent init sequence. The non-dvb-pll code for this
user is removed.
X88_BOARD_DNTV_LIVE_DVB_T_PRO digitalnow DNTV Live! DVB-T Pro
In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll:
SAA7134_BOARD_MD7134 Medion 7134
SAA7134_BOARD_ASUS_EUROPA2_HYBRID Asus Europa2 OEM
The saa7134 functions philips_fmd1216_tuner_init(),
philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are
deleted and the dvb-pll versions are used.
This should result in equivalent sleep, init, and tuning sequences being sent
to the tuner.
For the cxusb driver, only one board is effected:
USB_PID_MEDION_MD95700 Medion MD95700
This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c()
for init and tuning, respectively. These functions are effectively the same
as the dvb-pll versions. They call a tuner pass control function defined at
the dvb-usb level, but this does not matter, as this card does not have a
tuner pass control function (only the dib3000mb does). This board will gain
the sleep sequence, while init and tuning should be unchanged.

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.

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

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.

Rework the way the DMA buffer is handled and IRQs are generated.
ALSA uses a ring-buffer of multiple periods. Each period is supposed to
corrispond to one IRQ.
The existing driver was generating one interrupt per ring-buffer, as opposed
to per period. This meant that as soon as the IRQ was generated, the hardware
was already starting to re-write the beginning of the buffer. Since the DMA
happens on a per-line basis, there was only a narrow window to copy the data
out before the buffer was overwritten.
The cx88 core RISC program generator is modified so that it can set the IRQ
and counter flags to count every X lines of DMA transfer. This way we can
generate an interrupt every period instead of every full ring-buffer. Right
now only period of one line are supported, but it should be possible to
support longer periods. Note that a WRITE instruction generates an IRQ when
it starts, not when the transfer is finished. Thus to generate an IRQ when
line X is done, one must set the IRQ flag on the instruction that starts line
X+1, not the one that ends line X.
Change the line size so that there are four lines in the SRAM FIFO. If there
are not four lines, the analog output from the cx88's internal DACs is full of
clicks and pops.
Try to handle FIFO sync errors. Sometimes the chip generates many of these
errors before audio data starts. Up to 50 sync errors will be ignored and the
counter reset.
Have the IRQ handler save the RISC counter to the chip struct, and then have
the pointer callback use this to calculate the pointer position. We could
read the counter from the pointer callback, but sometimes the sync errors on
start up cause the counter to go crazy. ALSA sees this and thinks there has
been an overrun. The IRQ hander can avoid saving the counter position on
sync errors.
The chip "opened" flag wasn't necessary. ALSA won't try to open the same
substream multiple times. Probably this code was cut&pasted from the bt87x
driver, which has multiple sub-streams for one chip.
Do error checking for the videobuf mapping functions.
snd_card_cx88_runtime_free() is useless and can be deleted.

The driver should now pass the 'busy' state of the device to the cx2341x
module whenever controls are set or tried. -EBUSY will be returned if the
device is busy and the user attempts to modify certain 'dangerous' controls.
It concerns controls that change the audio or video compression mode and bitrates.
The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy)
to the cx2341x, effectively keeping the old behavior for now.
