67b60aad16 V4L/DVB (5215): Experimental support for signal strength/BER/uncorrectable count
After studying many hours worth of register dumps of MT352 and ZL10353 fed
with identically damaged RF signals I have made an educated guess at which
registers contain the AGC level, bit error rate and uncorrectable error
count values.
Implement the IOCTLs that return these values to userspace.

90060d32ca V4L/DVB (5212): Pvrusb2: Be more forgiving about encoder firmware size
The pvrusb2 driver previously rejected encoder firmware whose size was
not a multiple of 8192.  But this is a false check because it's
possible to find cx23416 firmware whose size doesn't conform to this
limit.  So change the firmware loader implementation to be more
forgiving of the image size.

8eec14295e V4L/DVB (5208): Kthread API conversion for dvb_frontend and av7110
dvb kernel_thread to kthread API port.  
It is running fine here, including module load/unload and software suspend
(which doesn't work as expected with or without this patch :).
I didn't convert the dvb_ca_en50221 as I do not have such an interface, but
if the conversion process is fine with the v4l-dvb maintainers, it should not
be a problem to send a patch for that too ...

b1e7df1d35 V4L/DVB (5204): Change videodev2.h licence to dual GPL/BSD
videodev2.h contains just the V4L2 API structs and defines.
By allowing this header file to be dual GPL/BSD will enable sharing
userspace apps between Linux and *BSD systems. It will also allow developing
newer BSD licensed drivers that can be shared on Linux and *BSD.
It should be noticed that most of the current V4L drivers, and v4l core
itself are GPL only. This won't be changed by this patch.

05ad390724 V4L/DVB (5166): Remove obsolete alias defines of CONFIG_* settings
The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly.  To work around
this, makefiles would define some new macro based on the setting of a
config variable.  e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary.  This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.

input_register_device() was changed to return an error code instead of
being void in 2.6.15.  Handle it with a macro wrapper in config.h.  For

required some trivial header re-ordering in budget-ci.c and ttusb_dec.c.
In kernel 2.6.15-rc1 a helper function called setup_timer() was added to
linux/timer.h.  Add to compat.h, but require that linux/timer.h be
included first to give the definition of struct timer_list.
A new 4GB DMA zone, __GFP_DMA32, was added in 2.6.15-rc2.  Alias it to
__GFP_DMA on older kernels.

b50e7fe993 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.

52ebc763d8 V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal only
The direct register access ioctls were defined as kernel internal only,
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 
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h 
to videodev2.h.

Types used in struct v4l2_register are changed to the userspace 
exportable versions (u32 -> __u32, etc). 

Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move 
the check into the video_ioctl2() dispatcher so it doesn't need to be 
duplicated in each driver's call-back function. CAP_SYS_ADMIN check is 
added to pvrusb2 (which doesn't use video_ioctl2).
