a53d2f299d [media] v4l2-async: remove unneeded .registered_async callback
The v4l2_subdev_core_ops .registered_async callback was added to notify
a subdev when its entity has been registered with the media device, to
allow for example to modify the media graph (i.e: adding entities/links).

But that's not needed since there is already a .registered callback in
struct v4l2_subdev_internal_ops that's called after the entity has been
registered with the media device in v4l2_device_register_subdev().

87904c3e82 drm/tegra: dsi: Enhance runtime power management
The MIPI DSI output on Tegra SoCs requires some external logic to
calibrate the MIPI pads before a video signal can be transmitted. This
MIPI calibration logic requires to be powered on while the MIPI pads are
being used, which is currently done as part of the DSI driver's probe
implementation.

This is suboptimal because it will leave the MIPI calibration logic
powered up even if the DSI output is never used.

On Tegra114 and earlier this behaviour also causes the driver to hang
while trying to power up the MIPI calibration logic because the power
partition that contains the MIPI calibration logic will be powered on
by the display controller at output pipeline configuration time. Thus
the power up sequence for the MIPI calibration logic happens before
it's power partition is guaranteed to be enabled.

Fix this by splitting up the API into a request/free pair of functions
that manage the runtime dependency between the DSI and the calibration
modules (no registers are accessed) and a set of enable, calibrate and
disable functions that program the MIPI calibration logic at points in
time where the power partition is really enabled.

While at it, make sure that the runtime power management also works in
ganged mode, which is currently also broken.

ed0bd721c9 hwrng: core - Improve description of the ->read() interface
Currently, very few RNG drivers support single byte reads using the
->read() interface. Of the 14 drivers in drivers/char/hw_random that
support this interface only three of these actually support max == 1.
The other behaviours vary between return 0, return 2, return 4 and return
-EIO).

This is not a problem in practice because the core hw_random code never
performs a read shorter than 16 bytes. The documentation for this function
already contrains the alignment of the buffer pointer, so let's also
guarantee that the buffer is at least as large as its alignment.

This constraint is intended to be the weakest guarantee neccessary to
allow driver writers to safely simplify their code.

223918e32a ftrace: Add ftrace_graph_ret_addr() stack unwinding helpers
When function graph tracing is enabled for a function, ftrace modifies
the stack by replacing the original return address with the address of a
hook function (return_to_handler).

Stack unwinders need a way to get the original return address.  Add an
arch-independent helper function for that named ftrace_graph_ret_addr().

This adds two variations of the function: one depends on
HAVE_FUNCTION_GRAPH_RET_ADDR_PTR, and the other relies on an index state
variable.

The former is recommended because, in some cases, the latter can cause
problems when the unwinder skips stack frames.  It can get out of sync
with the ret_stack index and wrong addresses can be reported for the
stack trace.

Once all arches have been ported to use
HAVE_FUNCTION_GRAPH_RET_ADDR_PTR, we can get rid of the distinction.

9a7c348ba6 ftrace: Add return address pointer to ftrace_ret_stack
Storing this value will help prevent unwinders from getting out of sync
with the function graph tracer ret_stack.  Now instead of needing a
stateful iterator, they can compare the return address pointer to find
the right ret_stack entry.

Note that an array of 50 ftrace_ret_stack structs is allocated for every
task.  So when an arch implements this, it will add either 200 or 400
bytes of memory usage per task (depending on whether it's a 32-bit or
64-bit platform).

Grsecurity has had a similar feature (called GRKERNSEC_KSTACKOVERFLOW=y)

bcaaa0c431 io-mapping.h: s/PAGE_KERNEL_IO/PAGE_KERNEL/
PAGE_KERNEL_IO is an x86-ism. Though it is used to define the pgprot_t
used for the iomapped region, it itself is just PAGE_KERNEL. On all
other arches, PAGE_KERNEL_IO is undefined so in a general header we must
refrain from using it.

v2: include pgtable for pgprot_combine()

cd34af40a0 scsi: cxlflash: Transition to application close model
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.

Merge tag 'rxrpc-rewrite-20160823-1' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

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.

eafe5cfe71 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.

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.

da0573026c soc: qcom: smd: Represent smd edges as devices
By representing each edge as its own device the channels are no longer
tied to being parented by the same smd device and as such an edge can
live as children of e.g. remoteproc instances.

0a0c08cae0 soc: qcom: smd: Simplify multi channel handling
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
works.
