Linus Torvalds fb09bafda6 Staging tree pull request for 3.5-rc1
Here is the big staging tree pull request for the 3.5-rc1 merge window.
 
 Loads of changes here, and we just narrowly added more lines than we
 added:
  622 files changed, 28356 insertions(+), 26059 deletions(-)
 
 But, good news is that there is a number of subsystems that moved out of
 the staging tree, to their respective "real" portions of the kernel.
 
 Code that moved out was:
 	- iio core code
 	- mei driver
 	- vme core and bridge drivers
 
 There was one broken network driver that moved into staging as a step
 before it is removed from the tree (pc300), and there was a few new
 drivers added to the tree:
 	- new iio drivers
 	- gdm72xx wimax USB driver
 	- ipack subsystem and 2 drivers
 
 All of the movements around have acks from the various subsystem
 maintainers, and all of this has been in the linux-next tree for a
 while.

in -next and pointed out by Olof Johanssen: a clean - but incorrect -
merge of the arch/arm/boot/dts/at91sam9g20.dtsi file.  Fix up manually

Volokh Konstantin 0982db20ab [media] staging: media: go7007: Adlink MPG24 board issues
This issuses applyed only for Adlink MPG24 board with go7007
 & wis2804, all whese changes was tested for continuos
 load&restart mode

This is minimal changes needed for start up go7007&wis2804 to work correctly
  in 3.4 branch

Changes:
  - When go7007 reset device, i2c was not worked (need rewrite GPIO5)
  - As wis2804 has i2c_addr=0x00/*really*/, so Need set I2C_CLIENT_TEN flag for validity
  - some main nonzero initialization, rewrites with kzalloc instead kmalloc
  - STATUS_SHUTDOWN was placed in incorrect place, so if firmware wasn`t loaded, we
    failed v4l2_device_unregister with kernel panic (OOPS)
  - some new v4l2 style features as call_all(...s_stream...) for using subdev calls
  - wis-tw2804.ko module code was incompatible with 3.4 branch in initialization v4l2_subdev parts.
    now i2c_get_clientdata(...) contains v4l2_subdev struct instead non standart wis_tw2804 struct

Adds:
  - Additional chipset tw2804 controls with: gain,auto gain,inputs[0,1],color kill,chroma gain,gain balances,
    for all 4 channels (from tw2804.pdf)
  - Power control for each 4 ADC (tw2804) up when s_stream(...,1), down otherwise

Hans Verkuil 5126f2590b [media] v4l2-dev: add flag to have the core lock all file operations
This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.

The drivers that didn't need this flag were:

drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c

The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.

Eventually this flag should go and it should not be used in new drivers.

There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).

It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.

For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.

While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.

I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

Gianluca Gennari abfac0b648 [media] as102: set optimal eLNA config values for each device
Ryley and me tested several eLNA configuration values with both a rooftop
and a portable antenna.

Ryley fuond out that the best value for his Elgato stick is indeed the current
default value 0xC0.

Instead, my stick is not capable of tuning VHF channels with 0xC0. With 0x80,
VHF works but the tuner sensitivity with the portable antenna is poor.
Instead, the value 0xA0 works with VHF and also gives good performance with
both the rooftop and the portable antenna.

So we concluded that devices built on the reference design work best with 0xA0,
while custom designs (Elgato, PCTV) seem to require 0xC0.

I also removed the unused parameter "minor" in struct as102_dev_t.

Gianluca Gennari abf9d00537 [media] as102: add __packed attribute to structs defined inside packed structs
This patch fixes a regression in kernel 3.3 due to this patch:

http://patchwork.linuxtv.org/patch/8332/

That patch changes "#pragma pack(1)" with "__packed" attributes, but it is not
complete. In fact, in the as102 driver there are a lot of structs/unions
defined inside other structs/unions.
When the "__packed" attribute is applied only on the external struct, it will
not affect the internal struct definitions.
So the regression is fixed by specifiying the "__packed" attribute also on the
internal structs.

This patch should go into 3.3, as it fixes a regression introduced in the new
kernel version.
