New Device Support
* Apex stx104 DAC
- new driver for this PC104 board. Right now DAC support only.
* ADI ad5064
- Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs.
- Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616,
ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629.
* ADI ad7192

* TI afe4404
- new driver for this heart rate monitor / pulse oximeter front end chip.
Staging Graduations

Originally held in staging to allow reworking into and MFD but as
that wasn't happening and isn't an absolute requirement we are moving
it out of staging.
Driver new features
* ms5611
- triggered buffer support
- IIO_CHAN_INFO_SCALE to aid the triggered buffer support.
Driver cleanups / reworks / fixes
* ad5064
- Use an enum for the register map layout to allow support of additional
chips (precursor to the new support listed above).
- Structural driver changes to allow support of the slightly different
handling for the ltc parts above.
* ad5933
- drop an exceptional & unnecessary for a function pointer.
* ad7606
- Cleanup the repeated copies of pm ops.
- consolidate the various channels specs via a sport of rearranging so only
one version is needed.

* hmc8543 (soon to move out of staging)
- Comment style fixes
- functionality of suspend and resume was swapped.
* spear-adc
- use devm_clk_dev instead of managing the clk lifetime by hand.
Core
* Use new dmaengine_terminate_sync call to avoid a theoretical race.
* Fix docs for mlock in struct iio_dev as it is correctly taken in some
drivers (docs used to say for core only).
* Add a helper function for calculating the scan index storage size within
the core cutting out some cut and paste versions of the same code.

This adds ADC0831/ADC0832/ADC0834/ADC0838 8-bit ADC driver.
I have tested with ADC0831 and ADC0832. The remaining ADC0834 and
ADC0838 are very similar to ADC0832.

This patch provides a way of working around a slight regression
introduced by commit 8463833590 ("mm: rework virtual memory
accounting").
Before that commit RLIMIT_DATA have control only over size of the brk
region. But that change have caused problems with all existing versions
of valgrind, because it set RLIMIT_DATA to zero.
This patch fixes rlimit check (limit actually in bytes, not pages) and
by default turns it into warning which prints at first VmData misuse:
"mmap: top (795): VmData 516096 exceed data ulimit 512000. Will be forbidden soon."
Behavior is controlled by boot param ignore_rlimit_data=y/n and by sysfs
/sys/module/kernel/parameters/ignore_rlimit_data. For now it set to "y".

Commit b76437579d ("procfs: mark thread stack correctly in
proc/<pid>/maps") added [stack:TID] annotation to /proc/<pid>/maps.
Finding the task of a stack VMA requires walking the entire thread list,
turning this into quadratic behavior: a thousand threads means a
thousand stacks, so the rendering of /proc/<pid>/maps needs to look at a
million combinations.
The cost is not in proportion to the usefulness as described in the
patch.
Drop the [stack:TID] annotation to make /proc/<pid>/maps (and
/proc/<pid>/numa_maps) usable again for higher thread counts.
The [stack] annotation inside /proc/<pid>/task/<tid>/maps is retained, as
identifying the stack VMA there is an O(1) operation.
Siddesh said:
"The end users needed a way to identify thread stacks programmatically and
there wasn't a way to do that. I'm afraid I no longer remember (or have
access to the resources that would aid my memory since I changed
employers) the details of their requirement. However, I did do this on my
own time because I thought it was an interesting project for me and nobody
really gave any feedback then as to its utility, so as far as I am
concerned you could roll back the main thread maps information since the
information is available in the thread-specific files"

- ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
- Avoid useless rebuilds for zboot.
- jz4780: Add NEMC, BCH and NAND device tree nodes
- Initial support for the MicroChip's DT platform. As all the device
drivers are missing this is still of limited use.
- Some Loongson3 cleanups.
- The unavoidable whitespace polishing.
- Reduce clock skew when synchronizing the CPU cycle counters on CPU
startup.
- Add MIPS R6 fixes.
- Lots of cleanups across arch/mips as fallout from KVM.

Driver updates for ARM SoCs. Some for SoC-family code under drivers/soc,
but also some other driver updates that don't belong anywhere else. We also
bring in the drivers/reset code through arm-soc.
Some of the larger updates:
- Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other
parts of the chip/board on these platforms, all proprietary protocols that
don't fit into other subsystems and live in drivers/soc for now.
- System bus driver for UniPhier
- Driver for the TI Wakeup M3 IPC device
- Power management for Raspberry PI

- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes"

This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings several
of the more minor and older platforms we have closer to multiplatform
support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
Much of this is moving around header files from old mach directories,
but there are also some cleanup patches of debug_ll (lowlevel debug
per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts.

Kmem accounting might incur overhead that some users can't put up with.
Besides, the implementation is still considered unstable. So let's
provide a way to disable it for those users who aren't happy with it.
To disable kmem accounting for cgroup2, pass cgroup.memory=nokmem at
boot time.

UBSAN uses compile-time instrumentation to catch undefined behavior
(UB). Compiler inserts code that perform certain kinds of checks before
operations that could cause UB. If check fails (i.e. UB detected)
__ubsan_handle_* function called to print error message.
So the most of the work is done by compiler. This patch just implements
ubsan handlers printing errors.
GCC has this capability since 4.9.x [1] (see -fsanitize=undefined
option and its suboptions).
However GCC 5.x has more checkers implemented [2].
Article [3] has a bit more details about UBSAN in the GCC.
[1] - https://gcc.gnu.org/onlinedocs/gcc-4.9.0/gcc/Debugging-Options.html
[2] - https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html
[3] - http://developerblog.redhat.com/2014/10/16/gcc-undefined-behavior-sanitizer-ubsan/
