f0f37e2f77 const: mark struct vm_struct_operations
* mark struct vm_area_struct::vm_ops as const
* mark vm_ops in AGP code

But leave TTM code alone, something is fishy there with global vm_ops
being used.

2bcd57ab61 headers: utsname.h redux
* remove asm/atomic.h inclusion from linux/utsname.h --
   not needed after kref conversion
 * remove linux/utsname.h inclusion from files which do not need it

NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.

b1912a85b5 media: video: Fix build in saa7164
-tip testing found that the x86 build (64-bit allyesconfig) fails due to:

  LD      vmlinux.o
  drivers/built-in.o:(.bss+0x4b648): multiple definition of `debug'
  arch/x86/built-in.o:(.kprobes.text+0x88): first defined here
  ld: Warning: size of symbol `debug' changed from 90 in
arch/x86/built-in.o to 4 in drivers/built-in.o
 make: *** [vmlinux.o] Error 1

This is because recent saa7164 changes introduced a global symbol
named 'debug'. The x86 platform code already defines a 'debug'
symbol. (which is named in a too generic way as well - but it
can be used nicely to weed out too generic symbols in drivers ;-)

Rename it to saa_debug.

388dba3047 Driver-Core: fix devnode callbacks for dabusb and industrialio

  drivers/media/video/dabusb.c:758: warning: initialization from incompatible pointer type

Due to this commit:

Missing the dabusb driver's dabusb_nodename() callback.

35ccf8f8ea V4L/DVB (13009): gspca - stv06xx-hdcs: Reduce exposure range
Due to rounding and clipping, exposure and gain settings do not map to
unique register values.  Rather than read the registers and report gain
and exposure that may be different than the values that were set, just
cache the latest values that were set and report them.  Reduce exposure
range from 0-65535 to 0-255 so libv4l's autogain doesn't take forever.
Remove vestiges of driver signal processing that is now handled by
libv4l.

6c119ff493 V4L/DVB (13002): Adds support for Zolid Hybrid PCI card:
http://linuxtv.org/wiki/index.php/Zolid_Hybrid_TV_Tuner

test status analog (PAL-B):
- Sometimes picture is noisy, but it becomes crystal clear after
  switching between channels. (happens for example at 687.25 Mhz)
- On a lower frequency (511.25 Mhz) the picture is always sharp, but
  lacks colour.
- No sound problems.
- radio untested.

Digital:
- DVB-T/H stream reception works.
- Would expect to see some more channels in the higher frequency region.

Overall is the impression that sensitivity still needs improvement
both in analog and digital modes.

	   This is not correct since vpif is common across capture

	   moved to this module
	2) Since there are common registers, a spinlock is added for
	   mutual exclusion.

This is the vpif capture bridge driver for DM6467.  This video
supports two video channels each having a tvp5147 device at
the input. This allows simultaneous capture of NTSC/PAL video
in each of this channel. Both MMAP and USERPTR io mechanism
are supported. Currently buffer allocation happens at REQBUF
ioctl request. Since USERPTR IO is supported, this is not an
issue since user applications can allocate buffers and pass
the user space address to the driver. Following are TODOs :-
	1) Adding support for allocation of buffers at init
	2) VBI/HBI data service

This has incorporated comments received against version v0
of the patch series.

0da2808ca2 V4L/DVB (12580): soc-camera: remove now unneeded subdevice group ID assignments
Since we are not using v4l2_device_call_* calls any more, we don't need to
initialise subdevice .grp_id any more. This also fixes compiler warnings on
64-bit platforms.

This makes the soc-camera interface for V4L2 subdevices thinner yet. Handle
gain and exposure internally in each driver just like all other controls.

Remove unneeded soc-camera operations, this also makes the soc-camera API to

6a6c878672 V4L/DVB (12534): soc-camera: V4L2 API compliant scaling (S_FMT) and cropping (S_CROP)
The initial soc-camera scaling and cropping implementation turned out to be
incompliant with the V4L2 API, e.g., it expected the user to specify cropping
in output window pixels, instead of input window pixels. This patch converts
the soc-camera core and all drivers to comply with the standard.

Use host-side image scaling when the client fails to set the requested format.
We also have to take scaling into account when performing host-side cropping.
Similar to cropping we try to use client-side scaling as much as possible to
preserve bus bandwidth and optimise the frame-rate.

The current tw9910 driver does not implement cropping correctly. Therefore, and
also because various rectangles in struct soc_camera_device are in user scale,
we cannot and shall not use rect_current as window location.

We should not change the format when requested to crop, only S_FMT can do this.

b897a91afb V4L/DVB (12525): soc-camera: prohibit geometry change with initialised buffers
Prohibit S_FMT and S_CROP with a different window width or height after video
buffer initialisation. This simplifies the work to be done in specific host and
client drivers, and it doesn't seem to make much sense to allow these changes.
We do however allow S_CROP with equal width and height to just move the window,
this doesn't affect video buffer management and is usually easy enough to
implement.
