f8d9f92452 arm64: cpuinfo: Expose MIDR_EL1 and REVIDR_EL1 to sysfs 
It can be useful for JIT software to be aware of MIDR_EL1 and
REVIDR_EL1 to ascertain the presence of any core errata that could
affect code generation.

This patch exposes these registers through sysfs:

/sys/devices/system/cpu/cpu$ID/regs/identification/midr_el1
/sys/devices/system/cpu/cpu$ID/regs/identification/revidr_el1

where $ID is the cpu number. For big.LITTLE systems, one can have a
mixture of cores (e.g. Cortex A53 and Cortex A57), thus all CPUs need
to be enumerated.

If the kernel does not have valid information to populate these entries
with, an empty string is returned to userspace.

612bd01fc6 ACPI: add support for loading SSDTs via configfs 
New tables can be loaded by creating directories under /config/table/
and writing the AML code into the aml table attribute. Various table
attributes will be readable once the table is successfully loaded.

Unloading tables is not supported at the moment, but it can be easily
implemented once ACPI loading functions provide a table handle to be
used for unloading.

aabb406008 First round of IIO new device support, features and cleanups for the 4.8 cycle. 
New device support
 * ads1015
   - add ads1115 support
 * bma220 accelerometer
   - new driver
   - triggered buffer support.
 * bmc150
   - add bmm150 support.
 * bmp280
   - bme280 support with addition of humidity channel.
 * max5487 potentiometer
   - new driver
 * MMA7660FC accelerometer.
   - New driver
 * st-pressure
   - support for the lps22hb
 * loop trigger.
   - This one is *nasty* but we have real applications (parrot drones) where
   it is useful.  The trigger basically spins as hard as it can firing off
   a new trigger each time all triggered devices come back to say they are
   done.  It doesn't hang a machine even when doing it on a dummy driver.
   A lot nicer than having this implemented within lots of device drivers
   anyway.
 
 Core stuff
 * Add support to create IIO devices via configfs (similar to we did for
 triggers a while back) + docs.
 * New channel types
   - IIO_ELECTRICAL_CONDUCTIVITY
 * Couple of MAINTAINERS patches to list the device tree bindings.
 * Make trigger ops structure non optional (comment fix). It hasn't been for
 an awful long time, but that's not what the description said.
 
 New features
 * ak8975
   - support adapters that are limited to byte data only by allowing the
   emulated block read i2c function that was recently introduced.
 * atlas-ph
   - support atlas-ec (electrical conductivity sensor)
 * bmi160
   - add available frequency and scale attributes to make the driver
   more user friendly (and avoid having to read the datasheet to know
   what will work).
 * dummy
   - move creation to configfs interface.  It's not real hardware so we
   are not that worried about the ABI breakage ;)
 * mma8452
   - oversampling ration support
 * nau7802
   - expose available gains to make life easier for userspace.
 * st-sensors
   - allow use of emulation for SMBus block reads as all the st parts support
   it.
 * ti-ads1015
   - list datasheet names to allow their use by inkernel consumers.
 * Various module alias additions to help auto probing.  Drop one redundant one
 as well.
 
 Cleanups
 * ad7266, ad7476, ad7887, ad7923, ad799x
   - use direct mode claim function rather than open coding it during sensor
   read (prevents switching on buffers mid read).
 * ad7793, ad7791
   - use direct mode claim to prevent frequency changes when buffers running.
 * afe440x - These are ABI breaking but the driver requires custom userspace
   code to do anything useful anyway and that is still being written and under
   control of TI.  Ultimately we may have other libraries to do pulse
   oximetry with these devices but we aren't aware of any yet.
   - kernel-doc format fixes
   - drop ifdef fun around of_match_ptr - it's not worth the mess to save
   a tiny amount of space.
   - drop some unnecessary register initializations.
   - drop the weird locked gain modes as they gain us nothing (can just set
   all gains separately).
   - remove handling of offset attributes seeing as no channels actually have
   them (oops)
   - Drop the LED3 input channel as it's an alias for ALED2.
   - *big one* remove channel names - an experiment that turned out to not
   make sense - see patch for details.
   - use regmap fields to clean up code.
   - tie the tia gain stages to appropriate channels in the ABI as that is
   what they really effect. Same with the LED currents.
   - cleanout some unused defines and fix a missnamed one.
 * atlas-ph
   - reorganise to allow support of other similar parts.
 * bmc150
   - document supported chips in kconfig help.
 * jsa1212
   - drop an unneeded i2c functionality check for functionality the driver
   doesn't use.
 * mxs-lradc
   - simply touch screen registration code.
   - remove the touch screen unregister as all devm based now.
   - disable only those channels that are masked in hardware stop (others
   are already dealt with elsewhere)
 * st-sensors
   - unexport st_sensors_get_buffer_element as nothing outside the st-sensors
   core driver uses it.
   - fix handling of failure to start up regulators.
 * tpl0102
   - drop an i2c functionality test for features that aren't needed.
 * ti-am335x
   - use variable name rather than type in sizeof for clarity.
   - use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit.
 
 Tools
 * Add install / uninstall to makefile.  Someone cares, so presumably
 some people will find it useful!
 *  generic_buffer
    - rename to iio_generic_buffer to line up with other tools.
    - handle cleanup when receiving signals
    - Add a --device-num option and a --trigger-num option rather than
    relying on naming which doesn't work if you have two of the same part.

Merge tag 'iio-for-4.8a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of IIO new device support, features and cleanups for the 4.8 cycle.

New device support
* ads1015
  - add ads1115 support
* bma220 accelerometer
  - new driver
  - triggered buffer support.
* bmc150
  - add bmm150 support.
* bmp280
  - bme280 support with addition of humidity channel.
* max5487 potentiometer
  - new driver
* MMA7660FC accelerometer.
  - New driver
* st-pressure
  - support for the lps22hb
* loop trigger.
  - This one is *nasty* but we have real applications (parrot drones) where
  it is useful.  The trigger basically spins as hard as it can firing off
  a new trigger each time all triggered devices come back to say they are
  done.  It doesn't hang a machine even when doing it on a dummy driver.
  A lot nicer than having this implemented within lots of device drivers
  anyway.

Core stuff
* Add support to create IIO devices via configfs (similar to we did for
triggers a while back) + docs.
* New channel types
  - IIO_ELECTRICAL_CONDUCTIVITY
* Couple of MAINTAINERS patches to list the device tree bindings.
* Make trigger ops structure non optional (comment fix). It hasn't been for
an awful long time, but that's not what the description said.

New features
* ak8975
  - support adapters that are limited to byte data only by allowing the
  emulated block read i2c function that was recently introduced.
* atlas-ph
  - support atlas-ec (electrical conductivity sensor)
* bmi160
  - add available frequency and scale attributes to make the driver
  more user friendly (and avoid having to read the datasheet to know
  what will work).
* dummy
  - move creation to configfs interface.  It's not real hardware so we
  are not that worried about the ABI breakage ;)
* mma8452
  - oversampling ration support
* nau7802
  - expose available gains to make life easier for userspace.
* st-sensors
  - allow use of emulation for SMBus block reads as all the st parts support
  it.
* ti-ads1015
  - list datasheet names to allow their use by inkernel consumers.
* Various module alias additions to help auto probing.  Drop one redundant one
as well.

Cleanups
* ad7266, ad7476, ad7887, ad7923, ad799x
  - use direct mode claim function rather than open coding it during sensor
  read (prevents switching on buffers mid read).
* ad7793, ad7791
  - use direct mode claim to prevent frequency changes when buffers running.
* afe440x - These are ABI breaking but the driver requires custom userspace
  code to do anything useful anyway and that is still being written and under
  control of TI.  Ultimately we may have other libraries to do pulse
  oximetry with these devices but we aren't aware of any yet.
  - kernel-doc format fixes
  - drop ifdef fun around of_match_ptr - it's not worth the mess to save
  a tiny amount of space.
  - drop some unnecessary register initializations.
  - drop the weird locked gain modes as they gain us nothing (can just set
  all gains separately).
  - remove handling of offset attributes seeing as no channels actually have
  them (oops)
  - Drop the LED3 input channel as it's an alias for ALED2.
  - *big one* remove channel names - an experiment that turned out to not
  make sense - see patch for details.
  - use regmap fields to clean up code.
  - tie the tia gain stages to appropriate channels in the ABI as that is
  what they really effect. Same with the LED currents.
  - cleanout some unused defines and fix a missnamed one.
* atlas-ph
  - reorganise to allow support of other similar parts.
* bmc150
  - document supported chips in kconfig help.
* jsa1212
  - drop an unneeded i2c functionality check for functionality the driver
  doesn't use.
* mxs-lradc
  - simply touch screen registration code.
  - remove the touch screen unregister as all devm based now.
  - disable only those channels that are masked in hardware stop (others
  are already dealt with elsewhere)
* st-sensors
  - unexport st_sensors_get_buffer_element as nothing outside the st-sensors
  core driver uses it.
  - fix handling of failure to start up regulators.
* tpl0102
  - drop an i2c functionality test for features that aren't needed.
* ti-am335x
  - use variable name rather than type in sizeof for clarity.
  - use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit.

Tools
* Add install / uninstall to makefile.  Someone cares, so presumably
some people will find it useful!
*  generic_buffer
   - rename to iio_generic_buffer to line up with other tools.
   - handle cleanup when receiving signals
   - Add a --device-num option and a --trigger-num option rather than
   relying on naming which doesn't work if you have two of the same part.

03cce00b4b First round of iio fixes for the 4.7 cycle. 
A slightly bumper set due to travel delaying the pull request and a fair few
 issues with the recent merge window patches.  Patches all over the place.
 The st-sensors one is probably the most involved, but definitly solves the
 issues seen.  Note there are some other issues around that handler
 (and the fact that a lot of boards tie a level interrupt chip to an
 edge interrupt only irq chip).  These are not regressions however, so
 will turn up the slow route.
 
 * core
   - iio_trigger_attach_pollfunc had some really badly wrong error handling.
   Another nasty triggered whilst chasing down issues with the st sensors
   rework below.
 * ad5592r
   - fix an off by one error when allocating channels.
 * am2315
   - a stray mutex unlock before we ever take the lock.
 * apds9960
   - missing a parent in the driver model (which should be the i2c device).
   Result is it doesn't turn up under /sys/bus/i2c/devices which some
   userspace code uses for repeatable device identification.
 * as3935
   - ABI usage bug which meant a processed value was reported as raw. Now
     reporting scale as well to ensure userspace has the info it needs.
   - Don't return processed value via the buffer - it doesn't conform to
     the ABI and will overflow in some cases.
   - Fix a wrongly sized buffer which would overflow trashing part of the
     stack.  Also move it onto the heap as part of the fix.
 * bh1780
   - a missing return after write in debugfs lead to an incorrect read and
     a null pointer dereference.
   - dereferencing the wrong pointer in suspend and resume leading to
     unpredictable results.
   - assign a static name to avoid accidentally ending up with no name if
     loaded via device tree.
 * bmi160
   - output data rate for the accelerometer was incorrectly reported. Fix it.
   - writing the output data rate was also wrong due to reverse parameters.
 * bmp280
   - error message for wrong chip ID gave the wrong expected value.
 * hdc100x
   - mask for writing the integration time was wrong allowin g us to get
   'stuck' in a particular value with no way back.
   - temperature reported in celsius rather than millicelsius as per the
   ABI.
   - Get rid of some incorrect data shifting which lead to readings being
   rather incorrect.
 * max44000
   - drop scale attribute for proximity as it is an unscaled value (depends
     on what is in range rather than anything knowable at the detector).
 * st-pressure
   - ABI compliance fixes - units were wrong.
 * st-sensors
   - We introduced some nasty issues with the recent switch over to a
   a somewhat threaded handler in that we broke using a software trigger
   with these devices.  Now do it properly.  It's a larger patch than ideal
   for a fix, but the logic is straight forward.
   - Make sure the trigger is initialized before requesting the interrupt.
   This matters now the interrupt can be shared. Before it was ugly and wrong
   but short of flakey hardware could not be triggered.
   - Hammer down the dataready pin at boot - otherwise with really
   unlucky timing things could get interestingly wedged requiring a hard power
   down of the chip.

2f37dd131c Staging and IIO driver update for 4.7-rc1 
Here's the big staging and iio driver update for 4.7-rc1.
 
 I think we almost broke even with this release, only adding a few more
 lines than we removed, which isn't bad overall given that there's a
 bunch of new iio drivers added.  The Lustre developers seem to have
 woken up from their sleep and have been doing a great job in cleaning up
 the code and pruning unused or old cruft, the filesystem is almost
 readable :)
 
 Other than that, just a lot of basic coding style cleanups in the churn.
 All have been in linux-next for a while with no reported issues.

623e47fc64 zram: introduce per-device debug_stat sysfs node 
debug_stat sysfs is read-only and represents various debugging data that
zram developers may need.  This file is not meant to be used by anyone
else: its content is not documented and will change any time w/o any
notice.  Therefore, the output of debug_stat file contains a version
string.  To avoid any confusion, we will increase the version number
every time we modify the output.

At the moment this file exports only one value -- the number of
re-compressions, IOW, the number of times compression fast path has
failed.  This stat is temporary any will be useful in case if any
per-cpu compression streams regressions will be reported.

b3c8eb5038 ibft: Expose iBFT acpi header via sysfs 
Some ethernet adapter vendors are supplying products which support optional
(payed license) features. On some adapters this includes a hardware iscsi
initiator.  The same adapters in a normal (no extra licenses) mode of
operation can be used as a software iscsi initiator.  In addition, software
iscsi boot initiators are becoming a standard part of many vendors uefi
implementations.  This is creating difficulties during early boot/install
determining the proper configuration method for these adapters when they
are used as a boot device.

The attached patch creates sysfs entries to expose information from the
acpi header of the ibft table.  This information allows for a method to
easily determining if an ibft table was created by a ethernet card's
firmware or the system uefi/bios.  In the case of a hardware initiator this
information in combination with the pci vendor and device id can be used
to ascertain any vendor specific behaviors that need to be accommodated.

42d236f8a4 dmaengine: qcom_hidma: add support for object hierarchy 
In order to create a relationship model between the channels and the
management object, we are adding support for object hierarchy to the
drivers. This patch simplifies the userspace application development.
We will not have to traverse different firmware paths based on device
tree or ACPI based kernels.

No matter what flavor of kernel is used, objects will be represented as
platform devices.

The new layout is as follows:

hidmam_10: hidma-mgmt@0x5A000000 {
	compatible = "qcom,hidma-mgmt-1.0";
	...

	hidma_10: hidma@0x5a010000 {
			compatible = "qcom,hidma-1.0";
			...
	}
}

The hidma_mgmt_init detects each instance of the hidma-mgmt-1.0 objects
in device tree and calls into the channel driver to create platform devices
for each child of the management object.

1276187c52 iio: health/afe440x: Make gain settings a modifier for the stages 
Currently the TIA gain settings are exported to userspace as sysfs
entries that do not clearly represent their internal relation to the
sampling stages. The gain settings are enabled on a per-stage basis,
this can be seen in figure 24 of the current AFE4404 datasheet.
These gain settings should therefore be tied to the channels that are
read during these stages. Make this change here.

24b9dea764 iio: health/afe440x: Remove channel names 
These AFEs have 4 ADC mesuring stages (called LED2, ALED2, LED1, and
ALED1 in the datasheet), we map these as channels, these stages can serve
different purposes depending on the application. For instance the AFE4404
has an additional LED (LED3), this LED can be timed to be active during
stage 2 (or anystage, but the datasheet describes this case and the name
of the stage reflects this use). This ability is used further in upcoming
parts that tie the front-end gain and the LED timings together. For these
reasons we remove explicit naming the channels.

Without channel names it is best that the index numbers are in order to
match the stage number, reorder the channel numbers.

8e996a2874 stm class: Support devices that override software assigned masters 
Some STM devices adjust software assigned master numbers depending on
the trace source and its runtime state and whatnot. This patch adds
a sysfs attribute to inform the trace-side software that master numbers
assigned to software sources will not match those in the STP stream,
so that, for example, master/channel allocation policy can be adjusted
accordingly.

ad352acbb9 coresight: etb10: splitting sysFS "status" entry 
The sysFS "status" entry conveys a wealth of information about
the status of the HW but goes agains the sysFS rule of one topic
per file.

This patch rectify the situation by adding read-only entries for
each of the field formaly displayed by "status".  The ABI
documentation is kept up to date.

5a45e01d41 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.

eb3798463f iio:imu:mpu6050: enhance mounting matrix support 
Add a new rotation matrix sysfs attribute compliant with IIO core
mounting matrix API.
Matrix is retrieved from "in_anglvel_mount_matrix" and
"in_accel_mount_matrix" sysfs attributes. It is declared into mpu6050 DTS
entry as a "mount-matrix" property.

Old interface is kept for backward userspace compatibility and may be
retrieved from legacy platform_data mechanism only.

dfc57732ad iio:core: mounting matrix support 
Expose a rotation matrix to indicate userspace the chip placement with
respect to the overall hardware system. This is needed to adjust
coordinates sampled from a sensor chip when its position deviates from the
main hardware system.

Final coordinates computation is delegated to userspace since:
* computation may involve floating point arithmetics ;
* it allows an application to combine adjustments with arbitrary
  transformations.

This 3 dimentional space rotation matrix is expressed as 3x3 array of
strings to support floating point numbers. It may be retrieved from a
"[<dir>_][<type>_]mount_matrix" sysfs attribute file. It is declared into a
device / driver specific DTS property or platform data.

e009a7e858 cxl: Allow initialization on timebase sync failures 
Failure to synchronize the PSL timebase currently prevents the
initialization of the cxl card, thus rendering the card useless. This
is too extreme for a feature which is rarely used, if at all. No
hardware AFUs or software is currently using PSL timebase.

This patch still tries to synchronize the PSL timebase when the card
is initialized, but ignores the error if it can't. Instead, it reports
a status via /sys.

   - update iio_event_monitor names to match new stuff.
   - make generic_buffer look for triggers ending in -trigger as we let these in
   for a number of drivers a long time back and now it is a fairly common
   option.
 
 Drivers
 * staging wide
   - convert bare unsigned usage to unsigned int to comply with coding style.
 * non staging wide:
   - since boiler plate gpio handling of interrupts has been moved into the
    ACPI core we don't need to include gpio/consumer.h in a load of drivers so
    drop it.
 * ad7606
   - fix an endian casting sparse warning.
 * ak8975
   - fix a possible unitialized warning from gcc.
   - drop and unused field left over from earlier cleanups
   - fix a missing regulator_disable on exit.
 * at91-sama5d2
   - typo and indentation
   - missing IOMEM dependency.
   - cleanup mode register usage by avoidling erasing whole thing when changing
   the sampling frequency.
 * bmc150
   - use the core demux and available_scan_masks to simplify buffer handling
   - optimize the transfers in the trigger handler now we have a magic function
   to emulate bulk reads (under circumstances met here).  This matters with some
   rather dumb i2c adapters in particular.
   - use a single regmap_conf for all bus types as they were all the same.
 * bmg160
   - use the core demux and available_scan_masks to simplify the buffer handling
   - optimize the transfers in the trigger handler now we have a magic funciton
   to emulate bulk rads (under circumstances met here).
   - drop gpio interrupt probing from the driver (ACPI) as now handled by the
   ACPI core.
 * ina2xx-adc
   - update the CALIB register when RShunt changes.
   - fix scale for VShunt - in reality this error canceled out when used.
 * isl29028
   - use regmap to retrieve the struct device instead of carrying a second
   copy of it around.
 * kxcjk-1013
   - use core demux
   - optimize i2c transfers in the trigger handler.
 * mcp4531
   - refactor to use a pointer to access model parameters instead of indexing
     into the array each time.
 * mma8452
   - style fixes
   - avoid swtiching to active whenever the config changes
   - add missin i2c_device_id for mma8451
 * mpu6050
   - fix possible NULL dereference.
   - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
 * ms5611
   - fix a missing regulator_disable that left the regulator on during removal.
 * mxc4005
   - drop gpio interrupt handling for ACPI case from driver as the core now
   handles this case.
 * st-sensors
   - note that there are only ever a maximum of 3 axis on current st-sensors
   so just allocate a fixed sized buffer big enough for that.
 * tpl0102
   - change the i2c_check_functionality condition to bring it inline with other
     IIO users as EOPNOTSUPP.
 * tsl2563

  to emulate bulk rads (under circumstances met here).
  - drop gpio interrupt probing from the driver (ACPI) as now handled by the
  ACPI core.
* ina2xx-adc
  - update the CALIB register when RShunt changes.
  - fix scale for VShunt - in reality this error canceled out when used.
* isl29028
  - use regmap to retrieve the struct device instead of carrying a second
  copy of it around.
* kxcjk-1013
  - use core demux
  - optimize i2c transfers in the trigger handler.
* mcp4531
  - refactor to use a pointer to access model parameters instead of indexing
    into the array each time.
* mma8452
  - style fixes
  - avoid swtiching to active whenever the config changes
  - add missin i2c_device_id for mma8451
* mpu6050
  - fix possible NULL dereference.
  - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
  - fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
  - drop gpio interrupt handling for ACPI case from driver as the core now
  handles this case.
* st-sensors
  - note that there are only ever a maximum of 3 axis on current st-sensors
  so just allocate a fixed sized buffer big enough for that.
* tpl0102
  - change the i2c_check_functionality condition to bring it inline with other
    IIO users as EOPNOTSUPP.
* tsl2563
  - replace deprecated flush_scheduled_work

Pull orangefs filesystem from Mike Marshall.

This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months.  From
the documentation file:

 "OrangeFS is an LGPL userspace scale-out parallel storage system.  It
  is ideal for large storage problems faced by HPC, BigData, Streaming
  Video, Genomics, Bioinformatics.

  Orangefs, originally called PVFS, was first developed in 1993 by Walt
  Ligon and Eric Blumer as a parallel file system for Parallel Virtual
  Machine (PVM) as part of a NASA grant to study the I/O patterns of
  parallel programs.

  Orangefs features include:

    - Distributes file data among multiple file servers
    - Supports simultaneous access by multiple clients
    - Stores file data and metadata on servers using local file system
      and access methods
    - Userspace implementation is easy to install and maintain
    - Direct MPI support
    - Stateless"

see Documentation/filesystems/orangefs.txt for more in-depth details.
