Arjan van de Ven 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.

Hans J. Koch c0c7fa0966 V4L/DVB (4406): Convert radio-cadet to V4L2 API
This is a card with RDS capabilities. 
RDS specifications didn't change from V4L1 to V4L2, so that part should be OK. 
This patch changed the following stuff:
* The device can be opened multiple times. That's necessary because there are 
at least a radio application and an RDS application (rdsd) that want to 
open() the device.
* Added a poll() function. Every character device should have that, and rdsd 
expects it as it uses select() on that file descriptor.
* Converted the ioctls to V4L2. MUTE is not implemented correctly as the 
card doesn't seem to have a special bit for that. Probably there are a few 
more ioctls that should at least return 0 or an error.
As I do not own such a card, I couldn't test anything. If there is anybody out 
there who owns such an ancient card, please test and report. 
I just checked that the code compiles.

Mauro Carvalho Chehab 5e87efa3b2 V4L/DVB (4068): Removed all references to kernel stuff from videodev.h and videodev2.h
The videodev.h and videodev2.h describe the public API for V4L and V4L2.
It shouldn't have there any kernel-specific stuff. Those were moved to
v4l2-dev.h.
This patch removes some uneeded headers and include v4l2-common.h on all
V4L driver. This header includes device implementation of V4L2 API provided
on v4l2-dev.h as well as V4L2 internal ioctls that provides connections
between master driver and its i2c devices.

Arnd Bergmann 0d0fbf8152 V4L (926_2): Moves compat32 functions from fs to v4l subsystem
This moves the 32 bit ioctl compatibility handlers for
Video4Linux into a new file and adds explicit calls to them
to each v4l device driver.

Unfortunately, there does not seem to be any code handling
the v4l2 ioctls, so quite often the code goes through two
separate conversions, first from 32 bit v4l to 64 bit v4l,
and from there to 64 bit v4l2. My patch does not change
that, so there is still much room for improvement.

Also, some drivers have additional ioctl numbers, for
which the conversion should be handled internally to
that driver.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
