Pull security subsystem updates from James Morris:
 "The main change in this kernel is Casey's generalized LSM stacking
  work, which removes the hard-coding of Capabilities and Yama stacking,
  allowing multiple arbitrary "small" LSMs to be stacked with a default
  monolithic module (e.g.  SELinux, Smack, AppArmor).

  See
        https://lwn.net/Articles/636056/

  This will allow smaller, simpler LSMs to be incorporated into the

Tejun Heo 6fe29354be printk: implement support for extended console drivers
printk log_buf keeps various metadata for each message including its
sequence number and timestamp.  The metadata is currently available only
through /dev/kmsg and stripped out before passed onto console drivers.  We
want this metadata to be available to console drivers too so that console
consumers can get full information including the metadata and dictionary,
which among other things can be used to detect whether messages got lost
in transit.

This patch implements support for extended console drivers.  Consoles can
indicate that they want extended messages by setting the new CON_EXTENDED
flag and they'll be fed messages formatted the same way as /dev/kmsg.

 "<level>,<sequnum>,<timestamp>,<contflag>;<message text>\n"

If extended consoles exist, in-kernel fragment assembly is disabled.  This
ensures that all messages emitted to consoles have full metadata including
sequence number.  The contflag carries enough information to reassemble
the fragments from the reader side trivially.  Note that this only affects
/dev/kmsg.  Regular console and /proc/kmsg outputs are not affected by
this change.

* Extended message formatting for console drivers is enabled iff there
  are registered extended consoles.

* Comment describing /dev/kmsg message format updated to add missing
  contflag field and help distinguishing variable from verbatim terms.

Sergey Senozhatsky 6566d1a32b zram: add dynamic device add/remove functionality
We currently don't support on-demand device creation.  The one and only
way to have N zram devices is to specify num_devices module parameter
(default value: 1).  IOW if, for some reason, at some point, user wants
to have N + 1 devies he/she must umount all the existing devices, unload
the module, load the module passing num_devices equals to N + 1.  And do
this again, if needed.

This patch introduces zram control sysfs class, which has two sysfs
attrs:
- hot_add      -- add a new zram device
- hot_remove   -- remove a specific (device_id) zram device

hot_add sysfs attr is read-only and has only automatic device id
assignment mode (as requested by Minchan Kim).  read operation performed
on this attr creates a new zram device and returns back its device_id or
error status.

Usage example:
	# add a new specific zram device
	cat /sys/class/zram-control/hot_add
	2

	# remove a specific zram device
	echo 4 > /sys/class/zram-control/hot_remove

Returning zram_add() error code back to user (-ENOMEM in this case)

	cat /sys/class/zram-control/hot_add
	cat: /sys/class/zram-control/hot_add: Cannot allocate memory

NOTE, there might be users who already depend on the fact that at least
zram0 device gets always created by zram_init(). Preserve this behavior.

Ivan Khoronzhuk 863ef5ba29 Documentation: ABI: sysfs-firmware-dmi: add -entries suffix to file name
The dmi-sysfs module adds DMI table structures entries under
/sys/firmware/dmi/entries only, so rename documentation file to
sysfs-firmware-dmi-entries as more appropriate. Without renaming it's
confusing to differ this from sysfs-firmware-dmi-tables that adds raw
DMI table and actually adds "dmi" kobject.

Ivan Khoronzhuk d7f96f97c4 firmware: dmi_scan: add SBMIOS entry and DMI tables
Some utils, like dmidecode and smbios, need to access SMBIOS entry
table area in order to get information like SMBIOS version, size, etc.
Currently it's done via /dev/mem. But for situation when /dev/mem
usage is disabled, the utils have to use dmi sysfs instead, which
doesn't represent SMBIOS entry and adds code/delay redundancy when direct
access for table is needed.

So this patch creates dmi/tables and adds SMBIOS entry point to allow
utils in question to work correctly without /dev/mem. Also patch adds
raw dmi table to simplify dmi table processing in user space, as
proposed by Jean Delvare.

 There are also one new driver: the Cisco snic; the advansys driver has

 DMA API, the tape statistics patch got in and finally, there's a
 resuffle of SCSI header files to separate more cleanly initiator from

The current "mask" policy option matches files opened as MAY_READ,
MAY_WRITE, MAY_APPEND or MAY_EXEC.  This patch extends the "mask"
option to match files opened containing one of these modes.  For
example, "mask=^MAY_READ" would match files opened read-write.

Greg Kroah-Hartman 78a66b00d9 Third round of new IIO drivers, cleanups and functionality for the 4.2 cycle.
Given Linus announced a 4.8rc coming up, hopefully time for one more
 lot of IIO patches this cycle.  Some of these are actually
 improvements / fixes for patches earlier in the cycle.
 
 New device support
 * st_accel driver - support devices with 8 bit channels.
 
 Cleanup
 * A general cleanup of the iio tools under /tools/ from Hartmut.
   I'm more than a little embarassed by how bad some of these were! Are well,
   much more refined and less bug prone now.
   These cover lots of stuff like unhandled error returns, memory leaks as
   well as general refactoring to tidy the code up.
 * iio_simple_dummy - fix memory leaks in the init functions, drop some
   pointless error returns from functions that never generate errors and
   make the module parameter explicitly unsigned.
 * More buffer handling reworks from Lars-Peter, this time targetting hardware
   buffers (a little used corner that looks likely to get more use in the near
   future). Specifically:
   - Always compute the masklength as inkernel buffer users may need it.
   - Add a means of labeling which buffer modes a given buffer implementation
     supports.
   - In the case of hardware buffers, require strict scan matching rather than
     matching to a superset.  Currently the demux is bypassed by these drivers
     (this may well not change for efficiency reasons) so allowing a superset
     of channels to be selected would otherwise lead to more data than requested
     confusing userspace.
 
 Driver funcationality improvments
 * mmc35240 - adds a compensation to the raw values as borrowed form Memsic's
   own input driver.
 * mma8452
   - event support
   - event debouncing
   - high  pass filter configuration
   - triggers
 * vf610 - allow conversion mode to be adjusted
 
 Fixlets
 * mmc35240
   - Off by one error that by coincidence had no real effect.
   - i2c_device_name should be lowercase.
   - Lack of null terminator at end of attributes array.
   - Avoid computing the fractional part of the magnetic field by moving
     the scaling into userspace where floating point is available to simplify
     the maths.
   - Use a smaller sleep before assuming the measurement is done.  This is
     safe and improves the possible polling rate.
   - Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd
     code and the value used in the code seems to be correct.
 * stk3310 - make a local variable signed to ensure error handling works.
 * twl4030
   - fix calculation of the temperature sense current - bug unlikely
     to have ever been noticed as the difference is small.
   - Fix errors in descriptions.

  own input driver.
* mma8452
  - event support
  - event debouncing
  - high  pass filter configuration
  - triggers
* vf610 - allow conversion mode to be adjusted

Fixlets
* mmc35240
  - Off by one error that by coincidence had no real effect.
  - i2c_device_name should be lowercase.
  - Lack of null terminator at end of attributes array.
  - Avoid computing the fractional part of the magnetic field by moving
    the scaling into userspace where floating point is available to simplify
    the maths.
  - Use a smaller sleep before assuming the measurement is done.  This is
    safe and improves the possible polling rate.
  - Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd
    code and the value used in the code seems to be correct.
* stk3310 - make a local variable signed to ensure error handling works.
* twl4030
  - fix calculation of the temperature sense current - bug unlikely
    to have ever been noticed as the difference is small.
  - Fix errors in descriptions.

Stefan Agner bf04c1a367 iio: adc: vf610: implement configurable conversion modes
Support configurable conversion mode through sysfs. So far, the
mode used was low-power, which is enabled by default now. Beside
that, the modes normal and high-speed are selectable as well.

Use the new device tree property which specifies the maximum ADC
conversion clock frequencies. Depending on the mode used, the
available resulting conversion frequency are calculated
dynamically.

Seymour, Shane M 05545c92db st: implement tape statistics
This patch implements tape statistics in the st module via
sysfs. Current no statistics are available for tape I/O and there
is no easy way to reuse the block layer statistics for tape
as tape is a character device and does not have perform I/O in
sector sized chunks (the size of the data written to tape
can change). For tapes we also need extra stats related to
things like tape movement (via other I/O).

There have been multiple end users requesting statistics
including AT&T (and some HP customers who have not given
permission to be named). It is impossible for them
to investigate any issues related to tape performance
in a non-invasive way.

This patch provides support for the DS28EA00 digital thermometer.

The DS28EA00 provides an additional two pins for implementing a sequence
detection algorithm.  This feature allows you to determine the physical
location of the chip in the 1-wire bus without needing pre-existing
knowledge of the bus ordering.  Support is provided through the sysfs
w1_seq file.  The file will contain a single line with an integer value
