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.

Power management and ACPI material for v4.6-rc1, part 2
- Fix for an intel_pstate driver issue related to the handling of
MSR updates uncovered by the recent cpufreq rework (Rafael Wysocki).
- cpufreq core cleanups related to starting governors and frequency
synchronization during resume from system suspend and a locking
fix for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
- acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
Michael Neuling, Richard Cochran, Shilpasri Bhat).
- intel_idle driver update preventing some Skylake-H systems
from hanging during initialization by disabling deep C-states
mishandled by the platform in the problematic configurations (Len
Brown).
- Intel Xeon Phi Processor x200 support for intel_idle (Dasaratharaman
Chandramouli).
- cpuidle menu governor updates to make it always honor PM QoS
latency constraints (and prevent C1 from being used as the
fallback C-state on x86 when they are set below its exit latency)
and to restore the previous behavior to fall back to C1 if the next
timer event is set far enough in the future that was changed in 4.4
which led to an energy consumption regression (Rik van Riel, Rafael
Wysocki).
- New device ID for a future AMD UART controller in the ACPI driver
for AMD SoCs (Wang Hongcheng).
- Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
scaling (AVS) driver (David Wu).
- ACPI PCI resources management fix for the handling of IO space
resources on architectures where the IO space is memory mapped
(IA64 and ARM64) broken by the introduction of common ACPI
resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
- Fix for the ACPI backend of the generic device properties API
to make it parse non-device (data node only) children of an
ACPI device correctly (Irina Tirdea).
- Fixes for the handling of global suspend flags (introduced in 4.4)
during hibernation and resume from it (Lukas Wunner).
- Support for obtaining configuration information from Device Trees
in the PM clocks framework (Jon Hunter).
- ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
King, Geert Uytterhoeven).

Pull more power management and ACPI updates from Rafael Wysocki:
"The second batch of power management and ACPI updates for v4.6.
Included are fixups on top of the previous PM/ACPI pull request and
other material that didn't make into it but still should go into 4.6.
Among other things, there's a fix for an intel_pstate driver issue
uncovered by recent cpufreq changes, a workaround for a boot hang on
Skylake-H related to the handling of deep C-states by the platform and
a PCI/ACPI fix for the handling of IO port resources on non-x86

This is the bulk of GPIO changes for kernel v4.6:
Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model. We now finally make GPIO chips
devices. The gpio_chip will create a gpio_device which contains
a struct device, and this gpio_device struct is kept private.
Anything that needs to be kept private from the rest of the kernel
will gradually be moved over to the gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step
of a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices. We can now discover GPIOs properly from
userspace. We still have not come up with a way to actually *use*
GPIOs from userspace.
- To encourage people to use the character device for the future,
we have it always-enabled when using GPIO. The old sysfs ABI is
still opt-in (and can be used in parallel), but is marked as
deprecated. We will keep it around for the foreseeable future,
but it will not be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes. This dates back to when GPIO was an opt-in feature and
no shared library even existed: just a header file with proper
prototypes was provided and all semantics were up to the arch to
implement. These patches make the GPIO chip even more a proper
device and cleans out leftovers of the old in-kernel API here
and there. Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going
on, but we now return sane values in the vast majority of drivers
and the errorpath is sanitized. Some patches for powerpc, blackfin
and unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected
to SPI to obtain a dirt-cheap output-only GPIO expander.

dmaengine updates for 4.6
This is smallish update with minor changes to core and new driver and usual
updates. Nothing super exciting here..
- We have made slave address as physical to enable driver to do the mapping.
- We now expose the maxburst for slave dma as new capability so clients can
know this and program accordingly
- addition of device synchronize callbacks on omap and edma.
- pl330 updates to support DMAFLUSHP for Rockchip platforms.
- Updates and improved sg handling in Xilinx VDMA driver.
- New hidma qualcomm dma driver, though some bits are still in progress

firewire: ABI documentation: libhinawa uses firewire-cdev
Hinawa [https://github.com/takaswie/libhinawa/] is a library for access to IEEE 1394 devices. As a gobject introspection library, it facilitates writing applications in high-level programming languages. Besides generic I/O via /dev/fw* (firewire-cdev ABI), it also supports control of IEEE 1394 audio hardware via ALSA hwdep ABIs which are provided by sound/firewire drivers.

dmaengine: add Qualcomm Technologies HIDMA management driver
The Qualcomm Technologies HIDMA device has been designed to support virtualization technology. The driver has been divided into two to follow the hardware design. 1. HIDMA Management driver 2. HIDMA Channel driver Each HIDMA HW consists of multiple channels. These channels share some set of common parameters. These parameters are initialized by the management driver during power up. Same management driver is used for monitoring the execution of the channels. Management driver can change the performance behavior dynamically such as bandwidth allocation and prioritization. The management driver is executed in host context and is the main management entity for all channels provided by the device.

Switch attribute wakeup_data from binary to a text attribute. This makes it easier to handle in userspace and allows to use the output of tools like mode2 almost as is to set a wakeup sequence. Changing to a text format and values in microseconds also makes the userspace interface independent of the setting of SAMPLE_PERIOD in the driver.

Third set of IIO new device support, features and cleanups for the 4.6 cycle.
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

With this patchset we finally introduce our new routing protocol:
B.A.T.M.A.N. V. Its implementation started quite some years ago, but due to the big changes being introduced it took a while to be discussed, designed, worked, re-worked, tested and debugged (well, we're never done with the latest). The entire operation has basically been a team work involving all the core contributors together with other people interested in the project. The new protocol is divided into two main subcomponents, called respectively ELP and OGMv2. The former is in charge of dealing with the neighbour discovery and link quality estimation, while the latter implements the algorithm that spreads the metrics around the network and computes optimal paths. The biggest change introduced with B.A.T.M.A.N. V is the new metric: the protocol won't rely on packet loss anymore, but it will use the estimated throughput extracted directly from the wifi driver (when available) by querying cfg80211. Batman-adv will also send some unicast probing packets when an interface is not used for payload traffic to make sure that such values are current. The new protocol can be compiled-in or not like other features we have and when selected will pull in CFG80211 as dependency for the reason described above. Thanks to the big work brought up in the past by Marek Lindner, batman-adv can easily deal several protocol implementations, therefore compiling in this new version does not exclude the older. This means that the user is offered the option to choose the protocol when creating the mesh interface (default is the old one to keep backward compatibility). Along with the protocol there are some sysfs knobs that are introduced to fine tune some of its behaviours, but users are recommended to keep the default values unless they know what they are doing. The last patch is about advertising our own patchwork platform (thanks to Sven Eckelmann for having set that up!) in the MAINTAINERS file. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJW1AvOAAoJENpFlCjNi1MRKxsP/1BR8Wh3MrtNhX7MMe7PnZEQ p00kArkjtnZCbBVFbG3JduqYaOPnGyzCLgBgF3DnOxx8gAGUEu6fu4AQNNr9jiUM 4lPnPbe5NuvjzQW27fJDZMuy4Y1FLaJ5DeoYjDH48/YDNS38nzlPPtNwg0pJA2TG C22dM6CX9kzxiy5RETmjgIjK2fgIybudWtCv7BGZxNyiqMaq+bYD+ZJJ6/wbj/FV uKbWB28puJZ3U3qTJ6ygbhAq8moeubp/nbZeh2RGkhpmnS7LKgdLWyPxJLAEza7Z jbdhyAE2xDYaU2xxVdOH9GecSYeUlQ+mrBdEblo2cfKMgShwZBrNjQxCaJIHN3G9 ta44yUpjGFl6/HIQnzfNZD4bTRNnb/DeRTG5qWxdrGAbxZESsMPf1Ph/hZ+KvSZ5 7eSZPmVGRYl8hJaLc25bG8pCOLQRsx/54hXNqYRqmImiPQi4IRvKUQkEDXBpHrT+ EwChfIQvCJSzZQAljrhYP/ytg/CiZxNKgW1u8cJRlHRs3jbBxJUJ67gvf2yWdQdj Luc76uLA1++8QLqhny6AtLeRrr7mYDFnJuNjkwbqWFSyBK6r/lKS1L3ereTfeVIM 5VWMuEDlbWuPscufDJ6WDgWwTqypybjvYbnDlQV7xHap7OegyS/ukQVz2W5lXvS1 gGERfC8WeW1JnFb5TSAY =qd6p -----END PGP SIGNATURE----- Merge tag 'batman-adv-for-davem' of git://git.open-mesh.org/linux-merge Antonio Quartulli says: ==================== batman-adv 20160229 this is our (hopefully) latest batch of patches intended for net-next.

ima: support for kexec image and initramfs
Add IMA policy support for measuring/appraising the kexec image and
initramfs. Two new IMA policy identifiers KEXEC_KERNEL_CHECK and
KEXEC_INITRAMFS_CHECK are defined.
Example policy rules:
measure func=KEXEC_KERNEL_CHECK
appraise func=KEXEC_KERNEL_CHECK appraise_type=imasig
measure func=KEXEC_INITRAMFS_CHECK
appraise func=KEXEC_INITRAMFS_CHECK appraise_type=imasig
Moving the enumeration to the vfs layer simplified the patches, allowing
the IMA changes, for the most part, to be separated from the other
changes. Unfortunately, passing either a kernel_read_file_id or a
ima_hooks enumeration within IMA is messy.
Option 1: duplicate kernel_read_file enumeration in ima_hooks
enum kernel_read_file_id {
...
READING_KEXEC_IMAGE,
READING_KEXEC_INITRAMFS,
READING_MAX_ID
enum ima_hooks {
...
KEXEC_KERNEL_CHECK
KEXEC_INITRAMFS_CHECK
Option 2: define ima_hooks as extension of kernel_read_file
eg: enum ima_hooks {
FILE_CHECK = READING_MAX_ID,
MMAP_CHECK,
In order to pass both kernel_read_file_id and ima_hooks values, we
would need to specify a struct containing a union.
struct caller_id {
union {
enum ima_hooks func_id;
enum kernel_read_file_id read_id;
};
};
Option 3: incorportate the ima_hooks enumeration into kernel_read_file_id,
perhaps changing the enumeration name.
For now, duplicate the new READING_KEXEC_IMAGE/INITRAMFS in the ima_hooks.
Changelog v4:
- replaced switch statement with a kernel_read_file_id to an ima_hooks
id mapping array - Dmitry
- renamed ima_hook tokens KEXEC_CHECK and INITRAMFS_CHECK to
KEXEC_KERNEL_CHECK and KEXEC_INITRAMFS_CHECK respectively - Dave Young

firmware: create directory hierarchy for sysfs fw_cfg entries
Each fw_cfg entry of type "file" has an associated 56-char, nul-terminated ASCII string which represents its name. While the fw_cfg device doesn't itself impose any specific naming convention, QEMU developers have traditionally used path name semantics (i.e. "etc/acpi/rsdp") to descriptively name the various fw_cfg "blobs" passed into the guest. This patch attempts, on a best effort basis, to create a directory hierarchy representing the content of fw_cfg file names, under /sys/firmware/qemu_fw_cfg/by_name. Upon successful creation of all directories representing the "dirname" portion of a fw_cfg file, a symlink will be created to represent the "basename", pointing at the appropriate /sys/firmware/qemu_fw_cfg/by_key entry. If a file name is not suitable for this procedure (e.g., if its basename or dirname components collide with an already existing dirname component or basename, respectively) the corresponding fw_cfg blob is skipped and will remain available in sysfs only by its selector key value.

firmware: introduce sysfs driver for QEMU's fw_cfg device
Make fw_cfg entries of type "file" available via sysfs. Entries are listed under /sys/firmware/qemu_fw_cfg/by_key, in folders named after each entry's selector key. Filename, selector value, and size read-only attributes are included for each entry. Also, a "raw" attribute allows retrieval of the full binary content of each entry. The fw_cfg device can be instantiated automatically from ACPI or the Device Tree, or manually by using a kernel module (or command line) parameter, with a syntax outlined in the documentation file.

First round of new IIO device support, features and cleanups for the 4.6 cycle.
Device Support
* ad5761
- new driver
* at91_sama5d2 ADC.
- new driver and MAINTAINERS entry.
- minor cleanups followed.
* atlas pH-SM
- new driver (this has possibly the prettiest data sheet I've ever seen)
* mcp3422
- mcp3425 ADC added.
* mcp4725
- mcp4726 DAC added.
* mma8452
- mma8451q accelerometer added.
* mpl115
- mpl115a1 added (a lot bigger than it seems as this is an SPI part whereas
previous parts were i2c).
* si7005
- Hoperf th02 (seems to be a repackaged part)
* si7020
- Hoperf th06 (seems to be a repackaged part)
New features
* Core
- IIO_PH type. Does what it says on the tin.
* max30100
- LED current configuration support.
* mcp320x
- more differential measurement combinations.
* mma8452
- free fall deteciton
- opt3001
- enable operation without a IRQ line.
- device tree docs. Somehow the original docs have disappeared down
a rabbit hole, so here is a new set.
* st-sensors
- Support active-low interrupts.
Cleanups and minor / not so minor reworks
* Documentation
- drop some defunct ABI from the docs in staging.
* presure / Kconfig
- white space cleanup.
* ad7150
- BIT macro usage
- Alignment fixes
* ad7192
- false indent fixed.
* ak8975
- constify the ak_def structures
* axp288
- drop a redundant double const.
* dht11
- substantial reliability improvements by being more tolerant
of missing start bits.
- simplify the decoding algorithm
* mma8452
- whitespace cleanup
* mpl115
- don't bother setting i2c_client_data as nothing uses it.
* mpu6050
- drop unused function parameter.
* opt3001
- extract integration time as constants.
- trivial refactoring.
