Pull media build fixes from Mauro Carvalho Chehab:
 "A series of patches that fix compilation on non-x86 archs.

  While most of them are just build fixes, there are some fixes for real
  bugs, as there are a number of drivers using dynamic stack allocation.
  A few of those might be considered a security risk, if the i2c-dev
  module is loaded, as someone could be sending very long I2C data that
  could potentially overflow the Kernel stack.  Ok, as using /dev/i2c-*
  devnodes usually requires root on usual distros, and exploiting it
  would require a DVB board or USB stick, the risk is not high"

Pull media updates from Mauro Carvalho Chehab:
 "This series include:
   - a new Remote Controller driver for ST SoC with the corresponding DT
     bindings
   - a new frontend (cx24117)
   - a new I2C camera flash driver (lm3560)
   - a new mem2mem driver for TI SoC (ti-vpe)
   - support for Raphael r828d added to r820t driver
   - some improvements on buffer allocation at VB2 core
   - usual driver fixes and improvements

  PS this time, we have a smaller number of patches.  While it is hard
  to pinpoint to the reasons, I believe that it is mainly due to:

   1) there are several patch series ready, but depending on DT review.
      I decided to grant some extra time for DT maintainers to look on
      it, as they're expecting to have more time with the changes agreed
      during ARM mini-summit and KS.  If they can't review in time for
      3.14, I'll review myself and apply for the next merge window.

   2) I suspect that having both LinuxCon EU and LinuxCon NA happening
      during the same merge window affected the development
      productivity, as several core media developers participated on
      both events"

8ceafbfa91 Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King:
 "This series cleans up the handling of DMA masks in a lot of drivers,
  fixing some bugs as we go.

  Some of the more serious errors include:
   - drivers which only set their coherent DMA mask if the attempt to
     set the streaming mask fails.
   - drivers which test for a NULL dma mask pointer, and then set the
     dma mask pointer to a location in their module .data section -
     which will cause problems if the module is reloaded.

  To counter these, I have introduced two helper functions:
   - dma_set_mask_and_coherent() takes care of setting both the
     streaming and coherent masks at the same time, with the correct
     error handling as specified by the API.
   - dma_coerce_mask_and_coherent() which resolves the problem of
     drivers forcefully setting DMA masks.  This is more a marker for
     future work to further clean these locations up - the code which
     creates the devices really should be initialising these, but to fix
     that in one go along with this change could potentially be very
     disruptive.

  The last thing this series does is prise away some of Linux's addition
  to "DMA addresses are physical addresses and RAM always starts at
  zero".  We have ARM LPAE systems where all system memory is above 4GB
  physical, hence having DMA masks interpreted by (eg) the block layers
  as describing physical addresses in the range 0..DMAMASK fails on
  these platforms.  Santosh Shilimkar addresses this in this series; the
  patches were copied to the appropriate people multiple times but were
  ignored.

  Fixing this also gets rid of some ARM weirdness in the setup of the
  max*pfn variables, and brings ARM into line with every other Linux
  architecture as far as those go"

0ca4343518 errno.h: remove "NFS" from descriptions in comments
glibc recently changed the error string for ESTALE to remove "NFS" -

https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=96945714ec61951cc748da2b4b8a80cf02127ee9

from: [ERR_REMAP (ESTALE)] = N_("Stale NFS file handle"),
to:   [ERR_REMAP (ESTALE)] = N_("Stale file handle"),

And some have expressed concern that the kernel's errno.h
comments still refer to NFS.

So make that change... note that this is a comment-only change,
and has no functional difference.

c2d3306991 GPIO bulk changes for the v3.13 development cycle
- Merged the GPIO descriptor API from Alexandre Courbot.
   This is a first step toward trying to get rid of the
   global GPIO numberspace for the future.
 
 - Add an API so that driver can flag that a certain GPIO
   line is being used by a irqchip backend for generating
   IRQs, so that we can enforce checks, like not allowing
   users to switch that line to an output at runtime, since
   this makes no sense. Implemented corresponding calls
   in a few select drivers.
 
 - ACPI GPIO cleanups, refactorings and switch to using the
   descriptor-based interface.
 
 - Support for the TPS80036 Palmas GPIO variant.
 
 - A new driver for the Broadcom Kona GPIO SoC IP block.
 
 - Device tree support for the PCF857x driver.
 
 - A set of ARM GPIO refactorings with the goal of getting
   rid of a bunch of custom GPIO implementations from the
   arch/arm/* tree:
 
   - Move the IOP GPIO driver to the GPIO subsystem and
     fix all users to use the gpiolib API for accessing
     GPIOs. Delete the old custom GPIO implementation.
 
   - Delete the unused custom PXA GPIO implemention.
 
   - Convert all users of the IXP4 custom GPIO
     implementation to use gpiolib and delete the custom
     implementation.
 
   - Delete the custom Gemini GPIO implementation, also
     completely unused.
 
 - Various cleanups and renamings.

Merge tag 'gpio-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO changes from Linus Walleij:
 "Here is the bulk of GPIO changes for the v3.13 development cycle.

  I've got ACKs for the things that affect other subsystems (or it's my
  own subsystem, like pinctrl).  Most of that pertain to an attempt from
  my side to consolidate and get rid of custom GPIO implementations in
  the ARM tree.  I will continue doing this.

  The main change this time is the new GPIO descriptor API, background
  for this can be found in Corbet's summary from this january in LWN:

    http://lwn.net/Articles/533632/

  Summary:

   - Merged the GPIO descriptor API from Alexandre Courbot.  This is a
     first step toward trying to get rid of the global GPIO numberspace
     for the future.

   - Add an API so that driver can flag that a certain GPIO line is
     being used by a irqchip backend for generating IRQs, so that we can
     enforce checks, like not allowing users to switch that line to an
     output at runtime, since this makes no sense.  Implemented
     corresponding calls in a few select drivers.

   - ACPI GPIO cleanups, refactorings and switch to using the

   - Support for the TPS80036 Palmas GPIO variant.

f095ca6b31 spi: Updates for v3.13
As well as the usual driver updates and cleanups there's a few
 improvements to the core here:
 
  - The start of some improvements to factor out more of the SPI message
    loop into the core.  Right now this is just simplifying the code a
    bit but hopefully next time around we'll also have managed to roll
    out some noticable performance improvements which drivers can take
    advantage of.
  - Support for loading modules for ACPI enumerated SPI devices.
  - Managed registration for SPI controllers.
  - Helper for another common I/O pattern.

0b1e73ed22 Staging driver update for 3.13-rc1
Here's the big drivers/staging/ update for 3.13-rc1.
 
 Nothing major here, just a _ton_ of fixes and cleanups, mostly driven by
 the new round of OPW applicants, but also there are lots of other people
 doing staging tree cleanups these days in order to help get the drivers
 into mergable shape.
 
 We also merge, and then revert, the ktap code, as Ingo and the other
 perf/ftrace developers feel it should go into the "real" part of the
 kernel with only a bit more work, so no need to put it in staging for
 now.
 
 All of this has been in linux-next for a while with no reported issues.

7f16e5c141 Merge tag 'v3.12' into drm-intel-next
I want to merge in the new Broadwell support as a late hw enabling
pull request. But since the internal branch was based upon our
drm-intel-nightly integration branch I need to resolve all the
oustanding conflicts in drm/i915 with a backmerge to make the 60+
patches apply properly.

We'll propably have some fun because Linus will come up with a
slightly different merge solution.

Conflicts:
	drivers/gpu/drm/i915/i915_dma.c
	drivers/gpu/drm/i915/i915_drv.c
	drivers/gpu/drm/i915/intel_crt.c
	drivers/gpu/drm/i915/intel_ddi.c
	drivers/gpu/drm/i915/intel_display.c
	drivers/gpu/drm/i915/intel_dp.c
	drivers/gpu/drm/i915/intel_drv.h

All rather simple adjacent lines changed or partial backports from
-next to -fixes, with the exception of the thaw code in i915_dma.c.
That one needed a bit of shuffling to restore the intent.

Oh and the massive header file reordering in intel_drv.h is a bit
trouble. But not much.

v2: Also don't forget the fixup for the silent conflict that results
in compile fail ...

The correct way for a driver to specify the coherent DMA mask is

ed5d6ca003 staging: drm/imx: fix return value check in ipu_add_subdevice_pdata()
In case of error, the function platform_device_register_data() returns
ERR_PTR() and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

46a51c8021 Staging: zram: Fix access of NULL pointer
This patch fixes the bug in reset_store caused by accessing NULL pointer.

The bdev gets its value from bdget_disk() which could fail when memory
pressure is severe and hence can return NULL because allocation of
inode in bdget could fail.

Hence, this patch introduces a check for bdev to prevent reference to a
NULL pointer in the later part of the code. It also removes unnecessary
check of bdev for fsync_bdev().

b1bdd4d3ed staging: ft1000: return values corrected in scram_start_dwnld
The ft1000 usb driver ignores expected Linux error codes, and uses two
values defined in ft1000_usb.h: STATUS_SUCCESS 0, and STATUS_FAILURE
0x1001; and sometimes -1. This patch changes the return values of the
function scram_start_dwnld to match the status of the handshake returned
by its helper functions, get_handshake and get_handshake_usb. If the
handshake fails, -ENETRESET is returned instead of the inappropriate
STATUS_FAILURE. Also, a new test has been added to differentiate failure
due to timeout from failure due to net reset (the default). -ETIMEDOUT
is returned in this case. Finally, 0 is returned on success instead of
STATUS_SUCCESS.

43fc69b112 staging: ft1000: change values of status return variable in write_dpram32_and_check
The ft1000 usb driver ignores expected Linux error codes, and uses two
values defined in ft1000_usb.h: STATUS_SUCCESS 0, and STATUS_FAILURE
0x1001; and sometimes -1. This patch changes the return value of the
function write_dpram_32_and check to 0 or -EREMOTEIO, respectively. The
relevant change was made in the helper function check_buffers (which is
only called from write_dpram32_and_check); it now returns 0 on success
and -EREMOTEIO on failure, and this is allowed to propagate through
write_dpram32_and_check. Assignments to the return variable status that
are no longer needed were removed as well. In one function up the call
chain, dsp_reload in ft1000_hw.c, the status variable was changed from
u16 to int to avoid collecting a signed value in an unsigned variable.

f0ac9bebf1 imx-drm: ipuv3-crtc: Invert IPU DI0 clock polarity
sig_cfg.clk_pol controls the 'di0_polarity_disp_clk' bit of register
IPUx_DI0_GENERAL through the following code in imx-drm/ipu-v3/ipu-di.c:

	if (!sig->clk_pol)
		di_gen |= DI_GEN_POLARITY_DISP_CLK;

With 'di0_polarity_disp_clk' bit set we do not have stable HDMI output on
mx6solo: contours of pictures look jittery and the white colour does not appear
really white.

Russell King initially reported this problem at:
http://www.spinics.net/lists/arm-kernel/msg279805.html

Inverting 'di0_polarity_disp_clk' leads to stable HDMI output image.

Tested on the following boards:
- mx6solowandboard (HDMI output)
- mx6qwandboard (HDMI output)
- mx6qsabrelite (LVDS)
- mx6qsabresd (HDMI output and LVDS)
- mx6dlsabresd (HDMI output)

The `S626_BF_*` bitfield position macros are no longer used and are just
a subset of the corresponding `S626_STDBIT_*` bitfield position macros.
Remove them.

2cea19faf1 staging: comedi: s626: expand standardized IndxSrc values
The 'IndxSrc' value for the standardized encoder setup is currently 1
bit wide and takes one of the following values:

  S626_INDXSRC_HARD = 0 // index source from hardware encoder
  S626_INDXSRC_SOFT = 1 // index source software controlled by IndxPol

However the hardware 'IndxSrcA' and 'IndxSrcB' values for the 'A' and
'B' counters are 2 bits wide.  The above standardized values 0 and 1
correspond to the hardware values 0 and 2.

In order to simplify conversions between the standardized values and
hardware values, expand the range of standardized values to cover all
four possible values.  The new values are as follows:

  S626_INDXSRC_ENCODER = 0  // index source from hardware encoder
  S626_INDXSRC_DIGIN = 1    // index source from digital inputs
  S626_INDXSRC_SOFT = 2     // index source s/w controlled by IndxPol
  S626_INDXSRC_DISABLED = 2 // index source disabled

(Note the change in value for `S626_INDXSRC_SOFT` and the replacement of
`S626_INDXSRC_HARD` with `S626_INDXSRC_ENCODER` for consistency with the
`CntSrc` values.)

0830ada537 staging: comedi: s626: make CRA and CRB setup conversions more readable
Use the new macros defined in "s626.h" for constructing and decomposing
'CRA', 'CRB' and standardized encoder setup values to make the
conversions between standardized encoder setup values, and CRA/CRB
register values easier to follow.

There is some messing about with the 'IndxSrc' values which are 1-bit
wide in the standardized encoder setup, and 2-bit wide in the 'CRA' and
'CRB' register values.  This will be addressed by a later patch.
