V4L/DVB (5147): Make vivi driver to use vmalloced pointers

Before this patch, vivi were simulating a scatter gather DMA transfer.
While this is academic, showing how stuff really works on a real PCI
device, this means a non-optimized code.
There are only two memory models that vivi implements:
1) kernel alloced memory. This is also used by read() method.
   On this case, a vmalloc32 buffer is allocated at kernel;
2) userspace allocated memory. This is used by most userspace apps.
   video-buf will store this pointer.
   a simple copy_to_user is enough to transfer data.
The third memory model scenario supported by video-buf is overlay mode.
This model is not implemented on vivi and unlikely to be implemented on
newer drivers, since now, most userspace apps do some post-processing
(like de-interlacing).
After this patch, some cleanups may be done at video-buf.c to avoid
allocating pages, when the driver doesn't need a PCI buffer. This is the
case of vivi and usb drivers.

but they are very useful for debugging hardware from userspace and are
used as such.  Officially export them.

VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER

exportable versions (u32 -> __u32, etc).

V4L/DVB (5095): Pvrusb2: Allow VIDIOC_S_FMT with -1 for resolution values

With the previous patch, mplayer started but was polling the video
device forever without any video actually coming out. Further analysis
showed that it does a VIDIOC_S_FMT with width and height set to -1 (!!!).
The code handling this only cares that both are lower than the minimum
range allowed so it ends up setting the size to 19x17 (!!) This pretty
much breaks the encoder here. Even if this breakage is yet another (TM)
result of my setup, setting the size to 19x17 by default would surprise
most users IMHO.
So, special case for -1 and interpret this to be a request for the
default size, please. Users can then set their favorite size both
through mplayer and through sysfs.
With this patch, mplayer finally works in pvr:// mode (not that we
really gain anything over operating it through sysfs with lirc,
sometime I might actually get off my lazy a** and contribute this
setup too)

V4L/DVB (5077): Bttv cropping support

Adds the missing VIDIOC_CROPCAP, G_CROP and S_CROP ioctls, permitting
applications to capture or overlay a subsection of the picture or to
extend the capture window beyond active video, into the VBI area and the
horizontal blanking. VBI capturing can start and end on any line,
including the picture area, and apps can capture different lines of each
field and single fields.
For compatibility with existing applications, the open() function
resets the cropping and VBI capturing parameters and a VIDIOC_S_CROP
call is necessary to actually enable cropping.
Regrettably in PAL-M, PAL-N, PAL-Nc and NTSC-JP mode the maximum image
width will increase from 640 and 768 to 747 and 923 pixels respectively.
Like the VBI changes however, this should only affect applications which
depend on former driver limitations, such as never getting more than 640
pixels regardless of the requested width.
Also, new freedoms require additional checks for conflicts and some
applications may not expect an EBUSY error from the VIDIOC_QBUF and
VIDIOCMCAPTURE ioctls. These errors should be rare though.
So far, the patch has been tested on a UP machine with a bt878 in PAL-
BGHI and NTSC-M mode using xawtv, tvtime, mplayer/mencoder, zapping/

     "automagically" reset to sane values on each mode change.

for min/max frequency at runtime.

hirange/lowrange fields of the v4l2_tuner struct instead, but then I see that

To do the mode switching we need to:
a) broadcast AUDC_SET_RADIO and
b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder.

The first is done by adding a new pvr2_i2c_op and having it trigger on
input change, the second by adding this command in pvr2_encoder_start()
and requesting an encoder restart on input change by setting
stale_subsys_mask appropriately.

The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly
provided by Hans Verkuil on the pvrusb2 mailing list. The idea to
implement mode switching this way (on input change) is due to Mike Isely.

Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure,
but I think this can be traced to a cornell student being the first to
