This implements SOCK_DESTROY for UDP sockets similar to what was done
for TCP with commit c1e64e298b8ca ("net: diag: Support destroying TCP
sockets.") A process with a UDP socket targeted for destroy is awakened
and recvmsg fails with ECONNABORTED.

Caching the adapter file descriptor and performing a close on behalf of
an application is a poor design. This is due to the fact that once a
file descriptor in installed, it is free to be altered without the
knowledge of the cxlflash driver. This can lead to inconsistencies
between the application and kernel. Furthermore, the nature of the
former design is more exploitable and thus should be abandoned.
To support applications performing a close on the adapter file that is
associated with a context, a new flag is introduced to the user API to
indicate to applications that they are responsible for the close
following the cleanup (detach) of a context. The documentation is also
updated to reflect this change in behavior.

David Howells says:
====================
rxrpc: Cleanups
Here are some cleanups for the AF_RXRPC rewrite:
(1) Remove some unused bits.
(2) Call releasing on socket closure is now done in the order in which
calls progress through the phases so that we don't miss a call
actively moving list.
(3) The rxrpc_call struct's channel number field is redundant and replaced
with accesses to the masked off cid field instead.
(4) Use a tracepoint for socket buffer accounting rather than printks.
Unfortunately, since this would require currently non-existend
arch-specific help to divine the current instruction location, the
accounting functions are moved out of line so that
__builtin_return_address() can be used.

popular back then!)
* atlas-ph-sensor
- ORP sensor support(I had to look up what one of these was)
* cio-dac
- New driver for Measurement Computing DAC boards
* dmard06
- New driver for Domintech DMARDO6 accelerometer. Also vendor prefix.

This is needed to allow client drivers to perform operations such as
configuring the trigger used.
* hid-sensors
- asynchronous resume support to avoid really long resume times.
* kxcjk-1013
- add the mysterious KIOX000A ACPI id seen in the wild.
* Tools
- lsiio now enumerates processed as well as raw channels.
Cleanup
* ad7298
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ad7793
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ade7854
- checkpatch fixups (alignment of parameters)
* atlas-ph-sensor
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
- Switch to REGCACHE_NONE as there are no useful register to cache.
* bma180
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* hdc100x
- Add mention of the HDC1000 and HDC1008 to the Kconfig help text.
* isl29018
- Add driver specific prefixes to defines and function names.

- This one wasn't locking to protect against mode switches during
raw_reads. Use the iio_claim_direct_mode function to fix this buglet.
* maxim-theromcouple
- Fix missing selects for triggered buffer support in Kconfig.
* nau7802
- Use complete instead of complete_all as only one completion at a time.
* sx9500
- Use complete instead of complete_all as only one completion at a time.
* us5182d
- Add a missing error code asignment instead of checking the result of
an already checked statement.
* vcnl4000
- Use BIT macro where appropriate.
- Refactor return codes in read_raw callback.
- Add some missing locking for concurrent accesses to the device.

First round of IIO fixes for the 4.8 cycle.
This is somewhat of a bumper set due to my unavailabilty earlier in the
month. The only slightly unusual ones are the dts updates for the
rockchip adc reset. The fix in the driver only makes sense with these
and the rockchip maintainer is happy with them going through IIO to
reach mainline.
Core stuff
* Fix an issue with a blocking op when !TASK_RUNNING. This been there
a while and snuck in with seemingly minor additions to some core
code paths.
* Tools
- generic_buffer failed to initialize the channel array pointer thus
in the case of no channels blows up trying to free a random memory
address.
* sw-trigger:
- Fix config group initialization when configfs is built as a module.
Drivers
* ad5933
- Fix an incorrect overwrite of an error value.
* ad799x
- A missed assignment of the update_scan_mode callback means buffered mode
doesn't work on the ad7991, ad7995 or ad7999.
* ads1015
- wrong pointer returned from i2c_get_clientdata (missmatch of assumptions)
* am2315
- Timestamps are reported, but never actually acquired from anywhere
(so always 0)
- missing buffer selects in Kconfig
* am335x adc
- Protect fifo1 from concurrent access.
- Increase timeout waiting for ADC to be long enough in all cases.
* as3935
- Timestamps are reported, but never actually acquired from anywhere
(so always 0)
* at91
- Fix reading of channel 3.
* atlas-ph-sensor
- Typo means that the scale of electrical conductivity readings is way off.
* bma220
- Timestamps are reported, but never actually acquired from anywhere
(so always 0)
- Missing buffer selects in Kconfig
* bmp280
- pass the write pointer to PTR_ERR (i.e. the one that was just checked
with IS_ERR).
- suspend /resume crash due to wrong assumption about what dev_get_drvdata
would return.
* hdc100x
- It superficially appeared that smbus_read_byte commands would allow
reading of the outputs in two goes. In reality it doesn't work, but
instead returns the same for the upper and lower bytes (nice catch from
Alison!)
* kxsd9
- Fix raw read return value to ensure it actually reports the value rather
than a blank string.
* max44000
- Missing buffer selects in Kconfig
* rockchip_saradc
- Add use of reset controller to enforce a clean state of the ADC.
Some bootloaders can leave it in an 'intersting' state and effectively
frozen without this. A couple of associated dts updates.
* stk8ba50
- Missing buffer selects in Kconfig
* stx104
- Fix a possible race due to use of devm_iio_device_register when there
was other stuff in the remove function.

Multi-channel clients split between several drivers need a way to close
individual channels, as these drivers might be removed individually.
With this in place the responsibility of closing additionally opened
channels to the client as well only concerning smd about the primary
channel.
With this approach we will only trigger removal of SMD devices based on
the state of the primary channel, however we get in sync with how rpmsg

Some touch controllers send out touch data in a similar way to a
greyscale frame grabber.
Add new device type VFL_TYPE_TOUCH:
- This uses a new device prefix v4l-touch for these devices, to stop
generic capture software from treating them as webcams. Otherwise,
touch is treated similarly to video capture.
- Add V4L2_INPUT_TYPE_TOUCH
- Add MEDIA_INTF_T_V4L_TOUCH
- Add V4L2_CAP_TOUCH to indicate device is a touch device
Add formats:
- V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas
- V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas
- V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data
- V4L2_TCH_FMT_TU08 for unsigned 8-bit touch data

- Atmel maXTouch (atmel_mxt_ts)

Mellanox mlx5 core driver updates 2016-08-20
This series contains several low level and API updates for mlx5 core
commands interface and mlx5_ifc.h to be shared as base code for net-next and
rdma mlx5 4.9 submissions.
From Saeed, ten patches that refactors old layouts of firmware commands which
were manually generated before we introduced the mlx5_ifc, now all of the firmware
commands inbox/outbox layouts moved to use mlx5_ifc and we remove the old
manually generated structures. Plus to those ten patches, we add two patches
that unifies mlx5 commands execution interface and improve the driver log messages
in that area.
From Hadar and Ilya, added the needed hardware bits and infrastructure for
minimum inline headers setting and encap/decap commands and capabilities,
needed for E-Switch offloads.
This series applies on top latest net-next and rdma/master, and smoothly merges with
the latest "Mellanox 100G mlx5 fixes 2016-08-16" series already applied into net branch.

a single bit whose meaning flipped] this can be supported with small

- Recognizing that VF is running on top of a legacy PF.
- Returning some slowpath configurations that are no longer needed

With recent topology changes in alsa-lib, driver data for
modules can now be passed in topology conf file using tuples.
This patch defines vendor specific tokens to describe private
data with tuples.
The allowed token types are UUID, string, bool, byte, short and
word. These tokens will be referenced by the vendor tuples in
the conf file.
In the topology conf file, multiple data blocks can be defined
for a widget which can be either tuple vendor array or blob. So,
each data block will be preceded by a descriptor to identify
size and type of block. These descriptors will be token
value pairs.
Tokens for module_id and loadable flag are not defined as these
are read from the DSP FW manifest.

The cec-funcs.h header was missing support for these three vendor-specific messages:

CEC_MSG_VENDOR_REMOTE_BUTTON_DOWN
Add wrappers for these messages.
I originally postponed adding these wrappers due to the fact that the argument is
just a byte array which cec-ctl couldn't handle at the time, and then I just forgot
to add them once the CEC framework was finalized.
It wasn't until an attempt to transmit a vendor specific command was made that I
realized that these wrappers were missing.

Currently if none of the requested logical addresses can be claimed, the
framework will fall back to the Unregistered logical address.
Add a flag to enable this explicitly. By default it will just go back to
the unconfigured state.
Usually Unregistered is not something you want since the functionality is
very limited. Unless the application has support for this, it will fail
to work correctly. So require that the application explicitly requests
this.

Up to now, RCU has assumed that the CPU-online process makes it from
CPU_UP_PREPARE to set_cpu_online() within one jiffy. Given the recent
rise of virtualized environments, this assumption is very clearly
obsolete. Failing to meet this deadline can result in RCU paying
attention to an incoming CPU for one jiffy, then ignoring it until the
grace period following the one in which that CPU sets itself online.
This situation might prove to be fatally disappointing to any RCU
read-side critical sections that had the misfortune to execute during
the time in which RCU was ignoring the slow-to-come-online CPU.
This commit therefore updates RCU's internal CPU state-tracking
information at notify_cpu_starting() time, thus providing RCU with
an exact transition of the CPU's state from offline to online.
Note that this means that incoming CPUs must not use RCU read-side
critical section (other than those of SRCU) until notify_cpu_starting()
time. Note also that the CPU_STARTING notifiers -are- allowed to use
RCU read-side critical sections. (Of course, CPU-hotplug notifiers are
rapidly becoming obsolete, so you need to act fast!)
If a given architecture or CPU family needs to use RCU read-side
critical sections earlier, the call to rcu_cpu_starting() from
notify_cpu_starting() will need to be architecture-specific, with
architectures that need early use being required to hand-place
the call to rcu_cpu_starting() at some point preceding the call to
notify_cpu_starting().

A reply parameter is added to the cec_msg_record_on/off functions in
cec-funcs.h. The standard mandates that Record Status shall be replied
to Record On, and it may be replied to Record Off.

This lock will be used to protect more than just the fhs list.
So rename it to just 'lock'.
