In the old days (before linux-3.0), SNMP counters were duplicated,
one for user context, and one for BH context.
After commit 8f0ea0fe3a03 ("snmp: reduce percpu needs by 50%")
we have a single copy, and what really matters is preemption being
enabled or disabled, since we use this_cpu_inc() or __this_cpu_inc()
respectively.
We therefore kill SNMP_INC_STATS_USER(), SNMP_ADD_STATS_USER(),
NET_INC_STATS_USER(), NET_ADD_STATS_USER(), SCTP_INC_STATS_USER(),
SNMP_INC_STATS64_USER(), SNMP_ADD_STATS64_USER(), TCP_ADD_STATS_USER(),
UDP_INC_STATS_USER(), UDP6_INC_STATS_USER(), and XFRM_INC_STATS_USER()
Following patches will rename __BH helpers to make clear their
usage is not tied to BH being disabled.

sd->input_queue_head is incremented for each processed packet
in process_backlog(), and read from other cpus performing
Out Of Order avoidance in get_rps_cpu()
Moving this field in a separate cache line keeps it mostly
hot for the cpu in process_backlog(), as other cpus will
only read it.
In a stress test, process_backlog() was consuming 6.80 % of cpu cycles,
and the patch reduced the cost to 0.65 %

The audit subsystem just started printing the name of the tty,
but that causes a build failure when CONFIG_TTY is disabled:
kernel/built-in.o: In function `audit_log_task_info':

kernel/built-in.o: In function `audit_set_loginuid':

Pull cgroup fixes from Tejun Heo:
"Two patches to fix a deadlock which can be easily triggered if memcg
charge moving is used.
This bug was introduced while converting threadgroup locking to a
global percpu_rwsem and is caused by cgroup controller task migration
path depending on the ability to create new kthreads. cpuset had a
similar issue which was fixed by performing heavy-lifting operations
asynchronous to task migration. The two patches fix the same issue in
memcg in a similar way. The first patch makes the mechanism generic
and the second relocates memcg charge moving outside the migration
path.
Given that we don't want to perform heavy operations while
writelocking threadgroup lock anyway, moving them out of the way is a
desirable solution. One thing to note is that the problem was
difficult to debug because lockdep couldn't figure out the deadlock
condition. Looking into how to improve that"

dmaengine_pcm currently only supports setups where FIFO reads/writes
correspond to exactly one sample, eg 16-bit sample data is transferred
via 16-bit FIFO accesses, 32-bit data via 32-bit accesses.
This patch adds support for setups with fixed width FIFOs where
multiple samples are packed into a larger word.
For example setups with a 32-bit wide FIFO register that expect
16-bit sample transfers to be done with the left+right sample data
packed into a 32-bit word.
Support for packed transfers is controlled via the
SND_DMAENGINE_PCM_DAI_FLAG_PACK flag in snd_dmaengine_dai_dma_data.flags
If this flag is set dmaengine_pcm doesn't put any restriction on the
supported formats and sets the DMA transfer width to undefined.
This means control over the constraints is now transferred to the DAI
driver and it's responsible to provide proper configuration and
check for possible corner cases that aren't handled by the ALSA core.

The default remains 127, which is good for most cases, and not even hit
most of the time, but then for some cases, as reported by Brendan, 1024+
deep frames are appearing on the radar for things like groovy, ruby.
And in some workloads putting a _lower_ cap on this may make sense. One
that is per event still needs to be put in place tho.
The new file is:
# cat /proc/sys/kernel/perf_event_max_stack
127
Chaging it:
# echo 256 > /proc/sys/kernel/perf_event_max_stack
# cat /proc/sys/kernel/perf_event_max_stack
256
But as soon as there is some event using callchains we get:
# echo 512 > /proc/sys/kernel/perf_event_max_stack
-bash: echo: write error: Device or resource busy
#
Because we only allocate the callchain percpu data structures when there
is a user, which allows for changing the max easily, its just a matter
of having no callchain users at that point.

This is more prep-work for the upcoming pty changes. Still just code
cleanup with no actual semantic changes.
This removes a bunch pointless complexity by just having the slave pty
side remember the dentry associated with the devpts slave rather than
the inode. That allows us to remove all the "look up the dentry" code
for when we want to remove it again.
Together with moving the tty pointer from "inode->i_private" to
"dentry->d_fsdata" and getting rid of pointless inode locking, this
removes about 30 lines of code. Not only is the end result smaller,
it's simpler and easier to understand.
The old code, for example, depended on the d_find_alias() to not just
find the dentry, but also to check that it is still hashed, which in
turn validated the tty pointer in the inode.
That is a _very_ roundabout way to say "invalidate the cached tty
pointer when the dentry is removed".
The new code just does
dentry->d_fsdata = NULL;
in devpts_pty_kill() instead, invalidating the tty pointer rather more
directly and obviously. Don't do something complex and subtle when the
obvious straightforward approach will do.
The rest of the patch (ie apart from code deletion and the above tty
pointer clearing) is just switching the calling convention to pass the
dentry or file pointer around instead of the inode.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing
Jonathan writes:
2nd set of new device support, features and cleanup for IIO in the 4.7 cycle.
Bit of a bumper set for new drivers but plenty of other stuff here as well!
New device support
* ad5592R ADC/DAC
- new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips.
* Aosong am2315 relative humidity
- new driver with triggered buffer support in follow up patch.
* bmi160 imu
- new driver
* bmp280
- bmp180 support - note there is support in the misc/bmp085 driver. Intent
is to remove that driver long term.
* invensense mpu6050
- cleanup leading to explicit support of mpu9150 with a good few cleanups
along the way.
* Hope RF hp03 pressure and temperature sensor.
- new driver
* maxim DS1803 potentiometer
- new driver
* maxim max44000 light and proximity sensor
- new driver built in a series of steps to support pretty much everything.
* ROHM BH1780 light sensor
- new driver. There is an existing driver in misc that this is pretty much
intended to replace. The discussion on whether to support the non standard
interface of that driver is some way is continuing.
* st-gyro
- lsm9ds0-gyro. The accel/magn side of this will take a while longer as
extensions to the st library are needed for cases where two types of sensor
share a single i2c address.
* ti-adc081c
- support the adc101c and adc121c
* Vishay VEML6070 UV sensor
- new driver.
New features
* core
- devm_ APIs for channel_get and channel_get_all. The first user of these
is the generic ADC based thermal driver. As it is going through the
thermal tree these will be picked up as a patch to that next cycle as that
is how the author preferred to do it.
- mounting matrix support. This new core support allows devices to provide
to userspace (typically from the device tree) allowing compensation for how
the sensor is mounted on the device. First examples are on UAVs but it
has a more mundane use on typical phone where the chip may be on the front
or the back of the circuit board and soldered at any angle. Includes
support for this ABI in ak8975 (which has an older interface, now
deprecated) and mpu6050.
* tools
- add a -a option to enable all available channels in generic_buffer sample.
Makes it somewhat easier to use.
* adis library and drivers
- support manual self test flag clearing. This has technically been broken
for a very long time - result is an offset on readings as the applied field
is on all the time.
* ak8975
- triggered buffer support
* bmc150
- spi support (including splitting the driver into core and i2c parts)
* bmp280
- oversampling support.
* dht11
- improved logging - useful to debug timing issues on this quirky device.
* st-sensors
- read each channel invidivually as not all support the optimization of
reading in bulk. This is technically a fix, but will need to be backported
if desired.
- support open drain and shared interrupts.
* ti-adc081c
- triggered buffer support.
Cleanups
* inkern
- white space fix.
* ad7606
- use the iio_device_claim_direct_mode call rather than open coding equiv.
* ad799x
- white space fix.
* ad9523
- unsigned -> unsigned int
* apds9660
- brace location tidying up.
- silence an uninitialized variable warning.
* ak8975
- else and brace on same line fix.
* at91_adc
- white space fixes.
* bmc150
- use regmap stored copy of the device pointer rather than having an
additional copy.
* bmg160
- use regmap stored copy of the device pointer rather than having an
additional copy.
* hid-sensors
- white space fixes.
* mcp3422
- white space fix.
* mma7455
- use regmap to retrieve the device struct rather than carrying another copy
in the private data.
* ms_sensors
- white space fix.
* mxs-lradc
- move current bindings out of staging - some will be shortly deprecated but
the reality is that we have device trees out there using them so they will
need to be supported for some time. They accidentally got left behind
when the driver graduated from staging.
- white space cleanup.
- set INPUT_PROP_DIRECT.
- move ts config into a better function.
- move the STMP reset out of the ADC init.
* vf610_adc
- case label indenting fix.

Redesign ethtool statistics handling and reporting in the driver:
1. Move counters to a separate file (en_stats.h).
2. Remove unnecessary dependencies between stats and strings.
3. Use counter descriptors which hold a name and offset for each counter,
and will be used to decide which counters will be exposed.
For example when adding a new software counter to ethtool, instead of:
1. Add to stats struct.
2. Add to strings struct in the same order.
3. Change macro defining number of software counters.
The only thing needed is to link the new counter to a counter descriptor.
VPort counters are a set of hardware traffic counters created automatically
for each virtual port opened.
PPort counters are a set of counters describing per physical port
performance statistics.
These counters are gathered from hardware register and divided to groups

For taking back the recent change of HDA HDMI fixes for i915 HSW/BDW.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

The recent bug report suggests that BCLK setup for i915 HSW/BDW needs
to be updated at each HDMI hotplug, not only at initialization and
resume. That is, we need to update HSW_EM4 and HSW_EM5 registers at
ELD notification, too. Otherwise the HDMI audio may be out of sync
and played in a wrong pitch.
However, the HDA codec driver has no access to the controller
registers, and currently the code managing these registers is in
hda_intel.c, i.e. local to the controller driver. For allowing the
explicit BCLK update from the codec driver, as in this patch, the
former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and
exposed as snd_hdac_i915_set_bclk(). This is called from both the HDA
controller driver and intel_pin_eld_notify() in HDMI codec driver.
Along with this change, snd_hdac_get_display_clk() gets dropped as
it's no longer used.

Since cfg80211 maintains separate BSS table entries for APs if the same
BSSID, SSID pair is seen on multiple channels, it is possible that it
can map the current_bss to a BSS entry on the wrong channel. This
current_bss will not get flushed unless disconnected and cfg80211
reports a wrong channel as the associated channel.
Fix this by introducing a new cfg80211_connect_bss() function which is
similar to cfg80211_connect_result(), but it includes an additional
parameter: the bss the STA is connected to. This allows drivers to
provide the exact bss entry that matches the BSS to which the connection
was completed.

Add support for the a station statistics netlink attribute:
NL80211_STA_INFO_RX_DURATION.
If present, this attribute contains the aggregate PPDU duration (in
microseconds) for all the frames from the peer. This is useful to
help understand the total time spent transmitting to us by all of
the connected peers.

Support checksum neutral ILA as described in the ILA draft. The low
order 16 bits of the identifier are used to contain the checksum
adjustment value.
The csum-mode parameter is added to described checksum processing. There
are three values:
- adjust transport checksum (previous behavior)
- do checksum neutral mapping
- do nothing
On output the csum-mode in the ila_params is checked and acted on. If
mode is checksum neutral mapping then to mapping and set C-bit.
On input, C-bit is checked. If it is set checksum-netural mapping is
done (regardless of csum-mode in ila params) and C-bit will be cleared.
If it is not set then action in csum-mode is taken.

The omap_mbox_save_ctx() and omap_mbox_restore_ctx() API were
previously provided to OMAP mailbox clients to save and restore
the mailbox context during system suspend/resume. The save and
restore functionality is now implemented through System PM driver
callbacks, and there is no need for these functions, so kill these
API.

OMAP mailbox devices can no longer be created in legacy non-DT
mode, all the relevant code has been cleaned up. The OMAP mailbox
driver will only support devices created from DT going forward,
so drop the legacy platform device support from the driver.
