The icn, act2000 and pcbit drivers are all for very old hardware,
and it is highly unlikely that anyone is actually still using them
on modern kernels, if at all.
All three drivers apparently are for hardware that predates PCI
being the common connector, as they are ISA-only and active
PCI ISDN cards were widely available in the 1990s.
Looking through the git logs, it I cannot find any indication of a
patch to any of these drivers that has been tested on real hardware,
only cleanups or global API changes.

Good to see several new contributors in this set - and more generally a
number of new 'faces' over this whole cycle.
Staging movements
* hmc5843
- out of staging.
* periodic RTC trigger
- driver dropped. This is an ancient driver (brings back some memories ;)
that was always somewhat of a bodge. Originally there was a driver that
never went into mainline that supported large numbers of periodict timers
on the PXA270 via this route. Discussions to have a generic periodic
timer subsystem never went anywhere. At the time RTC periodic
interrupts were real - now they are emulated using high resolution
timers so with the HRT driver this has become pointless.
New device support
* mpu6050 driver
- Add support for the mpu6500.
* TI tpl0102 potentiometer
- new driver.
* Vybrid SoC DAC
- new driver. The ADC on this SoC has been supported for a while, this
adds a separate driver for the DAC.
New Features
* hmc5844
- Attributes to configure the bias current (typically part of a self test)
This could be done before via a somewhat obscure custom interface.
This at least makes it easy to tell what is going on.
- Document all custom attributes.
* mpu6050
- Add support for calibration offset control and readback.
* ms5611
- power regulator support. This is always one that gets added the
first time someone has a board that needs it. Here it was needed,
hence it was added.
Cleanups / minor fixes
* tree wide
- clean up all the myriad different return values in response to a
failure of i2c_check_functionality. After discussions everyone seemed
happy wiht -EOPNOTSUPP which seems to describe the situation well.
I encouraged a tree wide cleanup to set a good example in future for
this.
* core
- Typos in the iio_event_spec documentation in iio.h
* afe4403
- select REGMAP_SPI to avoid dependency issues
- mark suspend/resume as __maybe_unused to avoid warnings
* afe4404
- mark suspend/resume as __maybe_unused to avoid warnings
* atlas-ph-sensor
- switch the regmap cache type from linear to rbtree to gain reading of
registers on initial startup. It's not immediately obvious, but
regmap flat is meant for high performances cases so doesn't read these
registers.
- use regmap_bulk_read in one case where it was using
i2c_smbus_read_i2c_block_data directly (unlike everything else that was
through regmap).
* ina2xx
- stype cleanups (lots of them!)
* isl29018
- Get the struct device back from regmap rather than storing another
copy of it in the private data. This cleanup makes sense in a number
of other drivers so patches may well follow.
* mpu6050
- style cleanups (lots of them!)
- improved return value handling
- use usleep_range to avoid the usual issues with very short msleeps.
- add some missing documentation.
* ms5611
- use the probed device name for the device rather than the driver name.

* palmas
- drop IRQF_EARLY_RESUME as no longer needed after genirq changes.

We didn't have a batch last week, so this one is slightly larger.
None of them are scary though, a handful of fixes for small DT pieces,
replacing properties with newer conventions.
Highlights:
- N900 fix for setting system revision
- onenand init fix to avoid filesystem corruption
- Clock fix for audio on Beaglebone-x15
- Fixes on shmobile to deal with CONFIG_DEBUG_RODATA (default y in 4.6)
+ misc smaller stuff.

Pull EFI fixes from Matt Fleming:
* Prevent accidental deletion of EFI variables through efivarfs that
may brick machines. We use a whitelist of known-safe variables to
allow things like installing distributions to work out of the box, and
instead restrict vendor-specific variable deletion by making
non-whitelist variables immutable (Peter Jones)

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,

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

that wasn't happening and isn't an absolute requirement we are moving
it out of staging.
Driver new features
* ms5611

Driver cleanups / reworks / fixes

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.

The arm,gic-v3 binding was written with good intentions and doesn't
enforce interrupt-cells to be 3, therefore making it easy to extend
the irq description in future if necessary:
> Cells 4 and beyond are reserved for future use.
Unfortunately, this sentence is immediately followed up with:
> When the 1st cell has a value of 0 or 1, cells 4 and beyond act as
> padding, and may be ignored. It is recommended that padding cells
> have a value of 0.
Consequently, any extensions to the PPI or SPI interrupt specifiers must
be able to work with random crap from legacy DTs, effectively
necessitating a new interrupt type in the first cell. Sigh.
This patch fixes the text so that additional, reserved cells are
required to be zero. This looks like a reasonable thing to require and
is already satisifed by the .dts files in-tree.

threadgroup and cgroup mutexes and the recent threadgroup locking

"rm -rf" is bricking some peoples' laptops because of variables being
used to store non-reinitializable firmware driver data that's required
to POST the hardware.
These are 100% bugs, and they need to be fixed, but in the mean time it
shouldn't be easy to *accidentally* brick machines.
We have to have delete working, and picking which variables do and don't
work for deletion is quite intractable, so instead make everything
immutable by default (except for a whitelist), and make tools that
aren't quite so broad-spectrum unset the immutable flag.

Workqueue used to guarantee local execution for work items queued
without explicit target CPU. The guarantee is gone now which can
break some usages in subtle ways. To flush out those cases, this
patch implements a debug feature which forces round-robin CPU
selection for all such work items.
The debug feature defaults to off and can be enabled with a kernel
parameter. The default can be flipped with a debug config option.

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"
