547472b8e1 ipv4: Disallow non-namespace aware protocols to register.
All in-tree ipv4 protocol implementations are now namespace
aware.  Therefore all the run-time checks are superfluous.

Reject registry of any non-namespace aware ipv4 protocol.
Eventually we'll remove prot->netns_ok and this registry
time check as well.

03878bb473 [media] s5p-fimc: fimc-lite: Prevent deadlock at STREAMON/OFF ioctls
This patch fixes regression introduced in commit 6319d6a002beb26631
'[media] fimc-lite: Add ISP FIFO output support'.
In case of a configuration where video is captured at the video node
exposed by the FIMC-LITE driver there is a following video pipeline:
sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node
In this situation s_stream() handler of the FIMC-LITE.n is called
back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video
node, through vb2_stream_on/off(), start/stop_streaming and
fimc_pipeline_call(set_stream). The fimc->lock mutex is already held
then, before invoking vidioc_streamon/off. So it must not be taken
again in the s_stream() callback in this case, to avoid a deadlock.
This patch makes fimc->out_path atomic_t so the mutex don't need
to be taken in the FIMC-LITE subdev s_stream() callback in the DMA
output case.

4e98fcfb95 Third set of IIO new drivers, cleanups and fixes for the 3.9 cycle
New drivers
 1) A driver for ST microelectronics sensors.  This driver already covers
    a large set of new parts (20 gyros, accelerometer and magnetometers)
    not currently covered by the existing drivers.  The intent moving forward
    is to merge this with the other drivers for similar parts already in tree.
    The lis3l02dq driver currently in staging/iio will be trivial, the lis3
    driver in misc more complex as it has a number of additional interfaces.
    Any merging in of the lis3 driver will rely on the not currently
    merged iio_input bridge driver and handling of freefall notifications
    etc.
 
 2) A driver for the itg3200 gyroscope.
 
 Graduations from staging
 1) Cleanup and move out of staging of the adxrs450 gyroscope driver.  The
    cleanup required was all minor but there were a couple of fixes hidden in
    there.
 
 Core and driver additions
 1) Initial work from Guenter Roeck on device tree support for IIO's provider/
    consumer code. Focuses on the iio_hwmon driver and the max1363 adc driver.
    The full device tree syntax is currently under discussion but should
    follow shortly.
 
 Cleanups and fixes
 1) Remove a noop function __iio_update_buffer
 2) Couple of small fixes and cleanups for the max1363

cc400e185c staging: comedi: check s->async for poll(), read() and write()
Some low-level comedi drivers (incorrectly) point `dev->read_subdev` or
`dev->write_subdev` to a subdevice that does not support asynchronous
commands.  Comedi's poll(), read() and write() file operation handlers
assume these subdevices do support asynchronous commands.  In
particular, they assume `s->async` is valid (where `s` points to the
read or write subdevice), which it won't be if it has been set
incorrectly.  This can lead to a NULL pointer dereference.

Check `s->async` is non-NULL in `comedi_poll()`, `comedi_read()` and
`comedi_write()` to avoid the bug.

4a79f73017 staging: comedi: remove 'comedi_autoconfig' module parameter
This module parameter is used to enable the auto config mechanism
in the comedi core. Most of the PCI, PCMCIA, and USB drivers have
been converted to use the auto config mechanism and will not attach
if it is disabled.

Since the 'comedi_autoconfig' parameter is defaulted to true, just
remove it so that the comedi drivers that use auto config will
always be able to attach.

167eb17e0b l2tp: create tunnel sockets in the right namespace
When creating unmanaged tunnel sockets we should honour the network namespace
passed to l2tp_tunnel_create.  Furthermore, unmanaged tunnel sockets should
not hold a reference to the network namespace lest they accidentally keep
alive a namespace which should otherwise have been released.

Unmanaged tunnel sockets now drop their namespace reference via sk_change_net,
and are released in a new pernet exit callback, l2tp_exit_net.

Change the subdevice operation used to write the digital outputs from
a (*insn_write) to a (*insn_bits) function. The (*insn_write) functions
are expected to write 'insn->n' number of samples. The (*insn_bits)
functions just write a single sample (insn->n = 1). Change the return
from '1' to 'insn->n' to clarify what the return is.

Using an (*insn_bits) function to write the digital outputs also allows
the user to read the current state of the output channels.

Fix the io operation used to update the digital outputs. The register is
only 8-bits and should by updated with an outb() not an outw().

Also, set the 'maxdata' for the subdevice. For digital io this value
should be '1' (digital io can only be 1 or 0).

Remove the setting of the len_chanlist for the subdevice. This variable
only has meaning for subdevices that support asynchronous commands. The
comedi core will initialize it appropriately during the postconfig.

826215d98f staging/xgifb: Consolidate if/else for 'identical' branches
Since XGI_LCDDesStruct is fully contained in XGI330_LCDDataDesStruct2
and the offsets for the first members is identical we can consolidate
the if/else branches here and use XGI330_LCDDataDesStruct2 for
everything.

1504ecbeec staging/xgifb: Don't write the same values x times
With the previous patch 'Move duplicated code for dram to helper
function' it becomes evident that the code is performing the same
thing 4 or 8 times in a row without changing arguments to the function
and thus writing the same values over and over again.

It was tested that these repeats are unnecessary.

-> we can safely remove them.

XGINew_SetDRAMDefaultRegister340 uses the same code fragment 4 times
with only a slight variation each time.
-> Move this code to a helper function - this saves some lines and

227dc1156c staging/xgifb: Replace XGI340_CR6B table with simple if/else
The XGI340_CR6B lookup table consists of the entries
{0xaa, 0xaa, 0xaa, 0xaa} for an index <= 2 and
{0x00, 0x00, 0x00, 0x00} for all other indices.

The only user XGINew_SetDRAMDefaultRegister340 loops over these 4 values
of a line with a for loop and since all entries are the same for each line
we can simply replace the whole lookup table with a simple if/else assignment.

1776fd059c OMAP/serial: Fix incorrect Rx FIFO threshold setting, LSR validation on Tx, and Tx FIFO IRQ generation
Original configuration of Rx FIFO threshold contained an error
that resulted Rx threshold to be effectively set to 1 character
instead of 16 characters, as noted in comments.
Checking LSR to contain UART_LSR_THRE bit set caused issue when
not all UART_IER_THRI interrupts have been properly handled.
This caused gap in Tx data, visible on high baud rates using
oscilloscope.
Setting OMAP_UART_SCR_TX_EMPTY bit in SCR caused UART_IER_THRI
interrupt to be raised only when Tx FIFO and Tx shift registers
are empty.

	drivers/net/vmxnet3/vmxnet3_drv.c
	drivers/net/wireless/iwlwifi/dvm/tx.c
	net/ipv6/route.c

The ipv6 route.c conflict is simple, just ignore the 'net' side change
as we fixed the same problem in 'net-next' by eliminating cached
neighbours from ipv6 routes.

The e1000e conflict is an addition of a new statistic in the ethtool
code, trivial.

The vmxnet3 conflict is about one change in 'net' removing a guarding
conditional, whilst in 'net-next' we had a netdev_info() conversion.

The iwlwifi conflict is dealing with a WARN_ON() conversion in
'net-next' vs. a revert happening in 'net'.

ba1066d2e9 [media] tuner-core: map audmode to STEREO for radio devices
Fixes a v4l2-compliance error: setting audmode to a value other than mono
or stereo for a radio device should map to MODE_STEREO.
The spec specifies that for radio devices only mono and stereo audmodes are
valid. If the user specifies another audmode in v4l2_tuner, then that should
be mapped to valid audmode. That didn't happen here.
Note that tuner drivers might decide to limit the possible audmode even
further if it only supports mono. In that case the tuner driver can set
audmode to mono. However, that new value wasn't copied back to t->audmode,
and that has been fixed as well in this patch.

With the recent twl related changes we can now get:

WARNING: arch/arm/mach-omap2/built-in.o(.text+0x15f88): Section mismatch in
reference from the function sdp3430_twl_gpio_setup() to the function

The function sdp3430_twl_gpio_setup() references
the function __init omap_twl4030_audio_init().
This is often because sdp3430_twl_gpio_setup lacks a __init
annotation or the annotation of omap_twl4030_audio_init is wrong.
