3d8e15dd6d KVM: new maintainer on the block
Avi has kept Gleb busy enough, and Radim has been helping me
for a while, so let's "reward" him with an entry in
MAINTAINERS.

eeca9a671a MAINTAINERS: add entry for QEMU
Gabriel merged support for QEMU FW CFG interface, but there's apparently
no official maintainer. It's also possible that this will grow more
interfaces in future.  I'll happily co-maintain it and handle pull
requests together with the rest of the PV stuff I maintain.

1b5caa3eaa Pin control fixes for the v4.6 series:
- On Super-H PFC (Renesas) controllers: only use dummies on
   legacy systems. This fixes a serious ethernet regression on
   a Renesas board.
 - Pistachio: Fix errors in the pin table.
 - Allwinner SunXi: fix the external interrupts to work.
 - Intel: fix so the high level interrupts start working, and
   fix a spurious interrupt issue.
 - Qualcomm ipq4019: fix the number of GPIOs provided (bump
   to 100), correct register offsets and handle GPIO mode
   properly.
 - Revert the revert on the revert so that Xway has a .to_irq()
   callback again.
 - Minor fixes to errorpaths and debug info.
 - A MAINTAINERS update.

This reverts commit 82ef33af9d.  It turns
out these machines are still out there, and the original patch broke
them.  So revert it, adding back the driver, so people's machines still
work properly.

eb7bfed901 First round of IIO new device support, features and cleanups for the 4.7 cycle.
New core support
 * UV light modifier (for intensity)
 * UV light index channel type.
 
 New device support
 * hp206c barometer and altimeter
   - new driver.
 * mcp4131 potentiometer
   - new driver supporting lots of parts from Microchip.
 * mma8452
   - FXLS8471Q support
 - NXP LPC18XX SOC ADC
   - new driver.
 - NXP LPC18XX SOC DAC
   - new driver.
 - rockchip_saradc
   - support rk3399
 * st accel
   - h3lis331dl support
 
 Staging driver removals
 * adis16204
   - obsolete part making it hard to get parts to test the driver in order
     to clean it up.
 * adis16220
   - obsolete part making it hard to get the parts test the driver in order
     to clean it up.
 
 Features
 * core
   - convenience functions to claim / release direct access to the device.
     Makes more consistent handling of this corner easier. Used in ad7192 driver.
 * ak8975
   - power regulator support.
 * at91-sama5d2
   - differential channel support.
 * mma8452
   - runtime pm support
   - drop device specific autosleep and use the runtime pm one instead.
 * ms5611
   - DT bindings
   - oversampling ratio support
 
 Cleanups and minor fixes
 * MAINTAINERS
   - Peter got married - hence name change!
 
 * Documentation
   - Fix a typo in in_proximity_raw description.
   - Add some missing docs for iio_buffer_access_funcs.
 
 * Tools
   - update iio_event_monitor names to match new stuff.
   - make generic_buffer look for triggers ending in -trigger as we let these in
   for a number of drivers a long time back and now it is a fairly common
   option.
 
 Drivers
 * staging wide
   - convert bare unsigned usage to unsigned int to comply with coding style.
 * non staging wide:
   - since boiler plate gpio handling of interrupts has been moved into the
    ACPI core we don't need to include gpio/consumer.h in a load of drivers so
    drop it.
 * ad7606
   - fix an endian casting sparse warning.
 * ak8975
   - fix a possible unitialized warning from gcc.
   - drop and unused field left over from earlier cleanups
   - fix a missing regulator_disable on exit.
 * at91-sama5d2
   - typo and indentation
   - missing IOMEM dependency.
   - cleanup mode register usage by avoidling erasing whole thing when changing
   the sampling frequency.
 * bmc150
   - use the core demux and available_scan_masks to simplify buffer handling
   - optimize the transfers in the trigger handler now we have a magic function
   to emulate bulk reads (under circumstances met here).  This matters with some
   rather dumb i2c adapters in particular.
   - use a single regmap_conf for all bus types as they were all the same.
 * bmg160
   - use the core demux and available_scan_masks to simplify the buffer handling
   - optimize the transfers in the trigger handler now we have a magic funciton
   to emulate bulk rads (under circumstances met here).
   - drop gpio interrupt probing from the driver (ACPI) as now handled by the
   ACPI core.
 * ina2xx-adc
   - update the CALIB register when RShunt changes.
   - fix scale for VShunt - in reality this error canceled out when used.
 * isl29028
   - use regmap to retrieve the struct device instead of carrying a second
   copy of it around.
 * kxcjk-1013
   - use core demux
   - optimize i2c transfers in the trigger handler.
 * mcp4531
   - refactor to use a pointer to access model parameters instead of indexing
     into the array each time.
 * mma8452
   - style fixes
   - avoid swtiching to active whenever the config changes
   - add missin i2c_device_id for mma8451
 * mpu6050
   - fix possible NULL dereference.
   - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
 * ms5611
   - fix a missing regulator_disable that left the regulator on during removal.
 * mxc4005
   - drop gpio interrupt handling for ACPI case from driver as the core now
   handles this case.
 * st-sensors
   - note that there are only ever a maximum of 3 axis on current st-sensors
   so just allocate a fixed sized buffer big enough for that.
 * tpl0102
   - change the i2c_check_functionality condition to bring it inline with other
     IIO users as EOPNOTSUPP.
 * tsl2563
   - replace deprecated flush_scheduled_work

86cf635a31 regulator: Rename files for Maxim PMIC drivers
Most Maxim PMIC regulator drivers are for sub-devices of Multi-Function
Devices with drivers under drivers/mfd. But for many of these, the same
object file name was used for both the MFD and the regulator drivers.

Having 2 different drivers with the same name causes a lot of confusion
to Kbuild, specially if these are built as module since only one module
will be installed and also exported symbols will be undefined due being
overwritten by the other module during modpost.

For example, it fixes the following issue when both drivers are module:

$ make M=drivers/regulator/
  ...
  CC [M]  drivers/regulator//max14577.o
  Building modules, stage 2.
  MODPOST 1 modules
WARNING: "maxim_charger_calc_reg_current" [drivers/regulator//max14577.ko] undefined!

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.

b8ba452683 Round two of 4.6 merge window patches
- A few minor core fixups needed for the next patch series

   of the series (three versions total).  Dave did not object, but did
   not respond either.  I've taken this as permission to move forward

 - The new Intel X722 iWARP driver
 - A huge set of updates to the Intel hfi1 driver.  Of particular interest
   here is that we have left the driver in staging since it still has an
   API that people object to.  Intel is working on a fix, but getting
   these patches in now helps keep me sane as the upstream and Intel's

Pull more rdma updates from Doug Ledford:
 "Round two of 4.6 merge window patches.

  This is a monster pull request.  I held off on the hfi1 driver updates
  (the hfi1 driver is intimately tied to the qib driver and the new
  rdmavt software library that was created to help both of them) in my
  first pull request.  The hfi1/qib/rdmavt update is probably 90% of
  this pull request.  The hfi1 driver is being left in staging so that
  it can be fixed up in regards to the API that Al and yourself didn't
  like.  Intel has agreed to do the work, but in the meantime, this
  clears out 300+ patches in the backlog queue and brings my tree and
  their tree closer to sync.

  This also includes about 10 patches to the core and a few to mlx5 to
  create an infrastructure for configuring SRIOV ports on IB devices.
  That series includes one patch to the net core that we sent to netdev@
  and Dave Miller with each of the three revisions to the series.  We
  didn't get any response to the patch, so we took that as implicit
  approval.

  Finally, this series includes Intel's new iWARP driver for their x722
  cards.  It's not nearly the beast as the hfi1 driver.  It also has a
  linux-next merge issue, but that has been resolved and it now passes
  just fine.

  Summary:

   - A few minor core fixups needed for the next patch series

   - The IB SRIOV series.  This has bounced around for several versions.
     Of note is the fact that the first patch in this series effects the
     net core.  It was directed to netdev and DaveM for each iteration

  He has an interesting series for muxes in the queue and agreed to look

  The octeon changes were applied pretty recently before the merge
  window.  I am aware.  They are the first (and relatively simple)
  patches of a larger overhaul to this driver.  In case something goes
  wrong with them, they are easy to fix (or revert).  The advantage I
  see is that they are out of the way, and I can concentrate on the next
  block of patches.  I really would like to apply the overhaul in
  smaller batches to avoid regressions.  And waiting a cycle for the
  introductory patches seemed too much of a delay for me"

  - Enable asynchronous system PM for the host device
  - Minor fixes and clean-ups
 
 SDHCI host:
 Throughout the years, the numbers of SDHCI variants have increased and so
 has also the numbers of SDHCI callbacks/quirks. The purpose of these
 callbacks/quirks were to enable SDHCI to deal with variant specific
 requirements, but unfortunate this method didn't scale. Instead we have
 ended up with a mess. Not only did the code become suboptimal but also
 highly fragile.
 
 Lately many discussions of how to move forward with SDHCI has taken place
 at the MMC mailing list. Step by step, we aim to turn SDHCI's common code
 into a set of library functions. This will enable for optimizations and
 allow some of the existing callbacks/quirks to be removed, which also
 should help to make the code less fragile.
 
 Therefore I am also really pleased to announce that Adrian Hunter (Intel)
 has volunteered to step in as the maintainer for SDHCI.
 
 Future wise, I hope the community around SDHCI will continue to grow and
 that this release cycle can be the starting point of moving SDHCI into a
 better shape. As a matter of fact, already in this cycle the re-factoring
 has begun, but of course there are also fixes and new features included.

26660a4046 Merge branch 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull 'objtool' stack frame validation from Ingo Molnar:
 "This tree adds a new kernel build-time object file validation feature
  (ONFIG_STACK_VALIDATION=y): kernel stack frame correctness validation.
  It was written by and is maintained by Josh Poimboeuf.

  The motivation: there's a category of hard to find kernel bugs, most
  of them in assembly code (but also occasionally in C code), that
  degrades the quality of kernel stack dumps/backtraces.  These bugs are
  hard to detect at the source code level.  Such bugs result in
  incorrect/incomplete backtraces most of time - but can also in some
  rare cases result in crashes or other undefined behavior.

  The build time correctness checking is done via the new 'objtool'
  user-space utility that was written for this purpose and which is
  hosted in the kernel repository in tools/objtool/.  The tool's (very
  simple) UI and source code design is shaped after Git and perf and
  shares quite a bit of infrastructure with tools/perf (which tooling
  infrastructure sharing effort got merged via perf and is already
  upstream).  Objtool follows the well-known kernel coding style.

  Objtool does not try to check .c or .S files, it instead analyzes the
  resulting .o generated machine code from first principles: it decodes
  the instruction stream and interprets it.  (Right now objtool supports
  the x86-64 architecture.)

  From tools/objtool/Documentation/stack-validation.txt:

   "The kernel CONFIG_STACK_VALIDATION option enables a host tool named
    objtool which runs at compile time.  It has a "check" subcommand
    which analyzes every .o file and ensures the validity of its stack
    metadata.  It enforces a set of rules on asm code and C inline
    assembly code so that stack traces can be reliable.

    Currently it only checks frame pointer usage, but there are plans to
    add CFI validation for C files and CFI generation for asm files.

    For each function, it recursively follows all possible code paths
    and validates the correct frame pointer state at each instruction.

    It also follows code paths involving special sections, like
    .altinstructions, __jump_table, and __ex_table, which can add
    alternative execution paths to a given instruction (or set of
    instructions).  Similarly, it knows how to follow switch statements,
    for which gcc sometimes uses jump tables."

  When this new kernel option is enabled (it's disabled by default), the
  tool, if it finds any suspicious assembly code pattern, outputs
  warnings in compiler warning format:

    warning: objtool: rtlwifi_rate_mapping()+0x2e7: frame pointer state mismatch
    warning: objtool: cik_tiling_mode_table_init()+0x6ce: call without frame pointer save/setup
    warning: objtool:__schedule()+0x3c0: duplicate frame pointer save
    warning: objtool:__schedule()+0x3fd: sibling call from callable instruction with changed frame pointer

  ... so that scripts that pick up compiler warnings will notice them.
  All known warnings triggered by the tool are fixed by the tree, most
  of the commits in fact prepare the kernel to be warning-free.  Most of
  them are bugfixes or cleanups that stand on their own, but there are
  also some annotations of 'special' stack frames for justified cases
  such entries to JIT-ed code (BPF) or really special boot time code.

  There are two other long-term motivations behind this tool as well:

   - To improve the quality and reliability of kernel stack frames, so
     that they can be used for optimized live patching.

   - To create independent infrastructure to check the correctness of
     CFI stack frames at build time.  CFI debuginfo is notoriously
     unreliable and we cannot use it in the kernel as-is without extra
     checking done both on the kernel side and on the build side.

  The quality of kernel stack frames matters to debuggability as well,
  so IMO we can merge this without having to consider the live patching
  or CFI debuginfo angle"

   2) New BPF types for per-cpu hash and arrap maps, from Alexei

   3) Make several TCP sysctls per-namespace, from Nikolay Borisov.

   4) Allow the use of SO_REUSEPORT in order to do per-thread processing
   of incoming TCP/UDP connections.  The muxing can be done using a
   BPF program which hashes the incoming packet.  From Craig Gallek.

   5) Add a multiplexer for TCP streams, to provide a messaged based
      interface.  BPF programs can be used to determine the message
      boundaries.  From Tom Herbert.

   6) Add 802.1AE MACSEC support, from Sabrina Dubroca.

   7) Avoid factorial complexity when taking down an inetdev interface
      with lots of configured addresses.  We were doing things like
      traversing the entire address less for each address removed, and
      flushing the entire netfilter conntrack table for every address as

  11) Extend ethtool so that larger link mode masks can be supported.

  12) Introduce devlink, which can be used to configure port link types
      (ethernet vs Infiniband, etc.), port splitting, and switch device
      level attributes as a whole.  From Jiri Pirko.

  13) Hardware offload support for flower classifiers, from Amir Vadai.

  14) Add "Local Checksum Offload".  Basically, for a tunneled packet
      the checksum of the outer header is 'constant' (because with the
      checksum field filled into the inner protocol header, the payload
      of the outer frame checksums to 'zero'), and we can take advantage

Pull block driver updates from Jens Axboe:
 "This is the block driver pull request for this merge window.  It sits
  on top of for-4.6/core, that was just sent out.

  This contains:

   - A set of fixes for lightnvm.  One from Alan, fixing an overflow,
     and the rest from the usual suspects, Javier and Matias.

   - A set of fixes for nbd from Markus and Dan, and a fixup from Arnd
     for correct usage of the signed 64-bit divider.

   - A set of bug fixes for the Micron mtip32xx, from Asai.

   - A fix for the brd discard handling from Bart.

   - Update the maintainers entry for cciss, since that hardware has
     transferred ownership.

   - Three bug fixes for bcache from Eric Wheeler.

   - Set of fixes for xen-blk{back,front} from Jan and Konrad.

   - Removal of the cpqarray driver.  It has been disabled in Kconfig
     since 2013, and we were initially scheduled to remove it in 3.15.

   - Various updates and fixes for NVMe, with the most important being:

        - Removal of the per-device NVMe thread, replacing that with a
          watchdog timer instead. From Christoph.

        - Exposing the namespace WWID through sysfs, from Keith.

        - Set of cleanups from Ming Lin.

        - Logging the controller device name instead of the underlying
          PCI device name, from Sagi.

        - And a bunch of fixes and optimizations from the usual suspects
          in this area"

Here is the big staging driver pull request for 4.6-rc1.
 
 Lots of little things here, over 1600 patches or so.  Notible is all of
 the good Lustre work happening, those developers have finally woken up
 and are cleaning up their code greatly.  The Outreachy intern
 application process is also happening, which brought in another 400 or
 so patches.  Full details are in the very long shortlog.
 
 All of these have been in linux-next with no reported issues.

1a46712aa9 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.
 
 - Texas Instruments TPIC2810
 
 - Texas Instruments TPS65218
 
 - Texas Instruments TPS65912

 "This is the bulk of GPIO changes for kernel v4.6.  There is quite a

cae8da047b SCSI misc on 20160315
This pull includes driver updates from the usual suspects (stex, hpsa,
 ncr5380, scsi_dh, qla2xxx, be2iscsi, hisi_sas, cxlflash, aacraid,
 mp3sas, megaraid_sas, ibmvscsi, ufs) plus an assortment of
 miscellaneous fixes.  The major user visible change of this pull is
 that we've moved from monotonically increasing host number to an ida
 allocated one (meaning the numbers get re-used) because someone
 managed to wrap the count in an iscsi system.  We don't believe there
 will be any adverse consequences of this.

Pull irq updates from Thomas Gleixner:
 "The 4.6 pile of irq updates contains:

   - Support for IPI irqdomains to support proper integration of IPIs to
     and from coprocessors.  The first user of this new facility is
     MIPS.  The relevant MIPS patches come with the core to avoid merge
     ordering issues and have been acked by Ralf.

   - A new command line option to set the default interrupt affinity
     mask at boot time.

   - Support for some more new ARM and MIPS interrupt controllers:
     tango, alpine-msix and bcm6345-l1

   - Two small cleanups for x86/apic which we merged into irq/core to
     avoid yet another branch in x86 with two tiny commits.

   - The usual set of updates, cleanups in drivers/irqchip.  Mostly in
     the area of ARM-GIC, arada-37-xp and atmel chips.  Nothing
     outstanding here"

Pull perf updates from Ingo Molnar:
 "Main kernel side changes:

   - Big reorganization of the x86 perf support code.  The old code grew
     organically deep inside arch/x86/kernel/cpu/perf* and its naming
     became somewhat messy.

     The new location is under arch/x86/events/, using the following
     cleaner hierarchy of source code files:

       perf/x86: Move perf_event.c .................. => x86/events/core.c

       perf/x86: Move perf_event_msr.c .............. => x86/events/msr.c

     (Borislav Petkov)

   - Update various x86 PMU constraint and hw support details (Stephane
     Eranian)

   - Optimize kprobes for BPF execution (Martin KaFai Lau)

   - Rewrite, refactor and fix the Intel uncore PMU driver code (Thomas
     Gleixner)

   - Rewrite, refactor and fix the Intel RAPL PMU code (Thomas Gleixner)

   - Various fixes and smaller cleanups.

  There are lots of perf tooling updates as well.  A few highlights:

  perf report/top:

     - Hierarchy histogram mode for 'perf top' and 'perf report',
       showing multiple levels, one per --sort entry: (Namhyung Kim)

       On a mostly idle system:

         # perf top --hierarchy -s comm,dso

       Then expand some levels and use 'P' to take a snapshot:

         # cat perf.hist.0
         -  92.32%         perf
               58.20%         perf
               22.29%         libc-2.22.so
                5.97%         [kernel]
                4.18%         libelf-0.165.so
                1.69%         [unknown]
         -   4.71%         qemu-system-x86
                3.10%         [kernel]
                1.60%         qemu-system-x86_64 (deleted)
         +   2.97%         swapper
         #

     - Add 'L' hotkey to dynamicly set the percent threshold for
       histogram entries and callchains, i.e.  dynamicly do what the
       --percent-limit command line option to 'top' and 'report' does.
       (Namhyung Kim)

  perf mem:

     - Allow specifying events via -e in 'perf mem record', also listing
       what events can be specified via 'perf mem record -e list' (Jiri
       Olsa)

  perf record:

     - Add 'perf record' --all-user/--all-kernel options, so that one
       can tell that all the events in the command line should be
       restricted to the user or kernel levels (Jiri Olsa), i.e.:

         perf record -e cycles:u,instructions:u

       is equivalent to:

         perf record --all-user -e cycles,instructions

     - Make 'perf record' collect CPU cache info in the perf.data file header:

         $ perf record usleep 1
         [ perf record: Woken up 1 times to write data ]
         [ perf record: Captured and wrote 0.017 MB perf.data (7 samples) ]
         $ perf report --header-only -I | tail -10 | head -8
         # CPU cache info:
         #  L1 Data                 32K [0-1]
         #  L1 Instruction          32K [0-1]
         #  L1 Data                 32K [2-3]
         #  L1 Instruction          32K [2-3]

       Will be used in 'perf c2c' and eventually in 'perf diff' to
       allow, for instance running the same workload in multiple
       machines and then when using 'diff' show the hardware difference.
       (Jiri Olsa)

     - Improved support for Java, using the JVMTI agent library to do
       jitdumps that then will be inserted in synthesized
       PERF_RECORD_MMAP2 events via 'perf inject' pointed to synthesized
       ELF files stored in ~/.debug and keyed with build-ids, to allow
       symbol resolution and even annotation with source line info, see
       the changeset comments to see how to use it (Stephane Eranian)

  perf script/trace:

     - Decode data_src values (e.g.  perf.data files generated by 'perf
       mem record') in 'perf script': (Jiri Olsa)

         # perf script
           perf 693 [1] 4.088652: 1 cpu/mem-loads,ldlat=30/P: ffff88007d0b0f40 68100142 L1 hit|SNP None|TLB L1 or L2 hit|LCK No <SNIP>
                                                                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
     - Improve support to 'data_src', 'weight' and 'addr' fields in
       'perf script' (Jiri Olsa)

     - Handle empty print fmts in 'perf script -s' i.e. when running
       python or perl scripts (Taeung Song)

  perf stat:

     - 'perf stat' now shows shadow metrics (insn per cycle, etc) in
       interval mode too.  E.g:

         # perf stat -I 1000 -e instructions,cycles sleep 1
         #         time   counts unit events
            1.000215928  519,620      instructions     #  0.69 insn per cycle
            1.000215928  752,003      cycles
         <SNIP>

     - Port 'perf kvm stat' to PowerPC (Hemant Kumar)

     - Implement CSV metrics output in 'perf stat' (Andi Kleen)

  perf BPF support:

     - Support converting data from bpf events in 'perf data' (Wang Nan)

     - Print bpf-output events in 'perf script': (Wang Nan).

         # perf record -e bpf-output/no-inherit,name=evt/ -e ./test_bpf_output_3.c/map:channel.event=evt/ usleep 1000
         # perf script
            usleep  4882 21384.532523:   evt:  ffffffff810e97d1 sys_nanosleep ([kernel.kallsyms])
             BPF output: 0000: 52 61 69 73 65 20 61 20  Raise a

             BPF string: "Raise a BPF event!"
         #

     - Add API to set values of map entries in a BPF object, be it
       individual map slots or ranges (Wang Nan)

     - Introduce support for the 'bpf-output' event (Wang Nan)

     - Add glue to read perf events in a BPF program (Wang Nan)

     - Improve support for bpf-output events in 'perf trace' (Wang Nan)

The root complexes used to access off-chip PCIe devices (called PEM units

access methods for the config space of the PCIe bridge.

Add a driver to provide these config space accessor functions.  Use the

0194621b22 IB/rdmavt: Create module framework and handle driver registration
This patch introduces the basics for a new module called rdma_vt. This new
driver is a software implementation of the InfiniBand verbs and aims to
replace the multiple implementations that exist and duplicate each others'
code.

While the call to actually register the device with the IB core happens in
rdma_vt, most of the work is still done in the drivers themselves. This
will be changing in a follow on patch this is just laying the groundwork
for this infrastructure.

MICROREAD_DRIVER_NAME is redefined in the only file where it is used,
so we can get rid of the header file and dead code altogether.

Documentation/usb.

This discussion was brought up by Guy Harris [0] during the
review of the USBIP dissector I wrote. For anyone interested:
support is available with the latest wireshark master/dev tree.
Simply select a packet from the usbip's tcp-stream you are

7da5ee09f1 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.

Introduce devlink infrastructure for drivers to register and expose to
userspace via generic Netlink interface.

There are two basic objects defined:
devlink - one instance for every "parent device", for example switch ASIC
devlink port - one instance for every physical port of the device.

This initial portion implements basic get/dump of objects to userspace.
Also, port splitter and port type setting is implemented.

supported by the watchdog timer is 1 second to 255 minutes. Timeouts

up the maintainer role for SDHCI. I am very pleased that Adrian Hunter
volunteered and accepted the challenge!

The SDHCI code is currently in quite poor quality, but we have agreed on
a way forward to try to reach a point where the SDHCI core becomes more of
a set of library functions. Each SDHCI driver variant can then decide
which functions to use and allows it to implement variant specific code,
without needing to also change SDHCI core code.

In the end we aim to get better optimized and maintainable code.

442f04c34a objtool: Add tool to perform compile-time stack metadata validation
This adds a host tool named objtool which has a "check" subcommand which
analyzes .o files to ensure the validity of stack metadata.  It enforces
a set of rules on asm code and C inline assembly code so that stack
traces can be reliable.

For each function, it recursively follows all possible code paths and
validates the correct frame pointer state at each instruction.

It also follows code paths involving kernel special sections, like
.altinstructions, __jump_table, and __ex_table, which can add
alternative execution paths to a given instruction (or set of
instructions).  Similarly, it knows how to follow switch statements, for
which gcc sometimes uses jump tables.

Here are some of the benefits of validating stack metadata:

a) More reliable stack traces for frame pointer enabled kernels

   Frame pointers are used for debugging purposes.  They allow runtime
   code and debug tools to be able to walk the stack to determine the
   chain of function call sites that led to the currently executing
   code.

   For some architectures, frame pointers are enabled by
   CONFIG_FRAME_POINTER.  For some other architectures they may be
   required by the ABI (sometimes referred to as "backchain pointers").

   For C code, gcc automatically generates instructions for setting up
   frame pointers when the -fno-omit-frame-pointer option is used.

   But for asm code, the frame setup instructions have to be written by
   hand, which most people don't do.  So the end result is that
   CONFIG_FRAME_POINTER is honored for C code but not for most asm code.

   For stack traces based on frame pointers to be reliable, all
   functions which call other functions must first create a stack frame
   and update the frame pointer.  If a first function doesn't properly
   create a stack frame before calling a second function, the *caller*
   of the first function will be skipped on the stack trace.

   For example, consider the following example backtrace with frame
   pointers enabled:

     [<ffffffff81812584>] dump_stack+0x4b/0x63
     [<ffffffff812d6dc2>] cmdline_proc_show+0x12/0x30
     [<ffffffff8127f568>] seq_read+0x108/0x3e0
     [<ffffffff812cce62>] proc_reg_read+0x42/0x70
     [<ffffffff81256197>] __vfs_read+0x37/0x100
     [<ffffffff81256b16>] vfs_read+0x86/0x130
     [<ffffffff81257898>] SyS_read+0x58/0xd0
     [<ffffffff8181c1f2>] entry_SYSCALL_64_fastpath+0x12/0x76

   It correctly shows that the caller of cmdline_proc_show() is
   seq_read().

   If we remove the frame pointer logic from cmdline_proc_show() by
   replacing the frame pointer related instructions with nops, here's
   what it looks like instead:

     [<ffffffff81812584>] dump_stack+0x4b/0x63
     [<ffffffff812d6dc2>] cmdline_proc_show+0x12/0x30
     [<ffffffff812cce62>] proc_reg_read+0x42/0x70
     [<ffffffff81256197>] __vfs_read+0x37/0x100
     [<ffffffff81256b16>] vfs_read+0x86/0x130
     [<ffffffff81257898>] SyS_read+0x58/0xd0
     [<ffffffff8181c1f2>] entry_SYSCALL_64_fastpath+0x12/0x76

   Notice that cmdline_proc_show()'s caller, seq_read(), has been
   skipped.  Instead the stack trace seems to show that
   cmdline_proc_show() was called by proc_reg_read().

   The benefit of "objtool check" here is that because it ensures that
   *all* functions honor CONFIG_FRAME_POINTER, no functions will ever[*]
   be skipped on a stack trace.

   [*] unless an interrupt or exception has occurred at the very
       beginning of a function before the stack frame has been created,
       or at the very end of the function after the stack frame has been
       destroyed.  This is an inherent limitation of frame pointers.

b) 100% reliable stack traces for DWARF enabled kernels

   This is not yet implemented.  For more details about what is planned,
   see tools/objtool/Documentation/stack-validation.txt.

c) Higher live patching compatibility rate

   This is not yet implemented.  For more details about what is planned,
   see tools/objtool/Documentation/stack-validation.txt.

To achieve the validation, "objtool check" enforces the following rules:

1. Each callable function must be annotated as such with the ELF
   function type.  In asm code, this is typically done using the
   ENTRY/ENDPROC macros.  If objtool finds a return instruction
   outside of a function, it flags an error since that usually indicates
   callable code which should be annotated accordingly.

   This rule is needed so that objtool can properly identify each
   callable function in order to analyze its stack metadata.

2. Conversely, each section of code which is *not* callable should *not*
   be annotated as an ELF function.  The ENDPROC macro shouldn't be used
   in this case.

   This rule is needed so that objtool can ignore non-callable code.
   Such code doesn't have to follow any of the other rules.

3. Each callable function which calls another function must have the
   correct frame pointer logic, if required by CONFIG_FRAME_POINTER or
   the architecture's back chain rules.  This can by done in asm code
   with the FRAME_BEGIN/FRAME_END macros.

   This rule ensures that frame pointer based stack traces will work as
   designed.  If function A doesn't create a stack frame before calling
   function B, the _caller_ of function A will be skipped on the stack
   trace.

4. Dynamic jumps and jumps to undefined symbols are only allowed if:

   a) the jump is part of a switch statement; or

   b) the jump matches sibling call semantics and the frame pointer has
      the same value it had on function entry.

   This rule is needed so that objtool can reliably analyze all of a
   function's code paths.  If a function jumps to code in another file,
   and it's not a sibling call, objtool has no way to follow the jump
   because it only analyzes a single file at a time.

5. A callable function may not execute kernel entry/exit instructions.
   The only code which needs such instructions is kernel entry code,
   which shouldn't be be in callable functions anyway.

   This rule is just a sanity check to ensure that callable functions
   return normally.

It currently only supports x86_64.  I tried to make the code generic so
that support for other architectures can hopefully be plugged in
relatively easily.

On my Lenovo laptop with a i7-4810MQ 4-core/8-thread CPU, building the
kernel with objtool checking every .o file adds about three seconds of
total build time.  It hasn't been optimized for performance yet, so
there are probably some opportunities for better build performance.

This is a follow-up for a similar change for other Renesas SoCs and

that patch as it was not yet present in mainline.

The motivation for the mailing list update is that Renesas SoCs are now
much wider than the SH architecture and there is some desire from some
for the linux-sh list to refocus on discussion of the work on the SH
architecture.

     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.
 * atlas ph sensor
   - add select IRQ_WORK
 * 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.

The Apex Embedded Systems STX104 is a 16-channel 16-bit analog input and
2-channel 16-bit analog output PC/104 card. The STX104 incorporates a
large one mega-sample FIFO.

This driver provides IIO support for the 2-channel DAC on the STX104.
The base port addresses for the devices may be configured via the "base"
module parameter array.

96173cc6a4 regulator: Rename files for max77686 and max77802 drivers
The max77686 and max77802 regulator drivers are for sub-devices of a MFD
driver for some PMIC blocks. But the same object file name (max77686.o)
was used for both the common MFD driver and the max77686 regulator one.

This confuses kbuild if both drivers are built as module causing the MFD
driver to not be copied when installing the modules.

Also, max77{686,802} are a quite generic name for MFD subdevices drivers
so it is better to rename them to max77{686,802}-regulator like it's the
case for most regulator drivers.

3c702e9987 gpio: add a userspace chardev ABI for GPIOs
A new chardev that is to be used for userspace GPIO access is
added in this patch. It is intended to gradually replace the
horribly broken sysfs ABI.

Using a chardev has many upsides:

- All operations are per-gpiochip, which is the actual
  device underlying the GPIOs, making us tie in to the
  kernel device model properly.

- Hotpluggable GPIO controllers can come and go, as this
  kind of problem has been know to userspace for character
  devices since ages, and if a gpiochip handle is held in
  userspace we know we will break something, whereas the
  sysfs is stateless.

- The one-value-per-file rule of sysfs is really hard to
  maintain when you want to twist more than one knob at a time,
  for example have in-kernel APIs to switch several GPIO
  lines at the same time, and this will be possible to do
  with a single ioctl() from userspace, saving a lot of
  context switching.

We also need to add a new bus type for GPIO. This is
necessary for example for userspace coldplug, where sysfs is
traversed to find the boot-time device nodes and create the
character devices in /dev.

This new chardev ABI is *non* *optional* and can be counted
on to be present in the future, emphasizing the preference
of this ABI.

The ABI only implements one single ioctl() to get the name
and number of GPIO lines of a chip. Even this is debatable:
see it as a minimal example for review. This ABI shall be
ruthlessly reviewed and etched in stone.

The old /sys/class/gpio is still optional to compile in,
but will be deprecated.

Unique device IDs are created using IDR, which is overkill
and insanely scalable, but also well tested.

than only API/ABI changes.  Drop those two entries, but leave
include/linux/syscalls.h and kernel/sys_ni.c to catch syscall-related

Remove support for dgap driver since there is no way to get
the firmware files required by the dgap driver into the linux-

1b06d64f73 gpio: Add GPIO support for the ACCES 104-DIO-48E
The ACCES 104-DIO-48E device provides 48 lines digital I/O via two
Programmable Peripheral Interface (PPI) chips of type 82C55. Bit C3 at
each 24-bit Group can be used as an external interrupt, triggered by a
rising edge.

This driver provides GPIO and IRQ support for these 48 channels of
digital I/O. The base port address for the device may be configured via
the dio_48e_base module parameter. The interrupt line number for the
device may be configured via the dio_48e_irq module parameter.

 "This is the main pull request for MIPS for 4.5 plus some 4.4 fixes.

  The executive summary:

   - 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.
   - Lots of minor fixes and changes for IEEE 754-2008 support to the
     FPU emulator / fp-assist software.
   - Minor Ralink, BCM47xx and bcm963xx platform support improvments.

a1b3695820 NTB: Add support for AMD PCI-Express Non-Transparent Bridge
This adds support for AMD's PCI-Express Non-Transparent Bridge
(NTB) device on the Zeppelin platform. The driver connnects to the
standard NTB sub-system interface, with modification to add hooks
for power management in a separate patch. The AMD NTB device has 3
memory windows, 16 doorbell, 16 scratch-pad registers, and supports
up to 16 PCIe lanes running a Gen3 speeds.

Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management and ACPI updates from Rafael Wysocki:
 "This includes fixes on top of the previous batch of PM+ACPI updates
  and some new material as well.

  From the new material perspective the most significant are the driver
  core changes that should allow USB devices to stay suspended over
  system suspend/resume cycles if they have been runtime-suspended
  already beforehand.  Apart from that, ACPICA is updated to upstream
  revision 20160108 (cosmetic mostly, but including one fixup on top of
  the previous ACPICA update) and there are some devfreq updates the
  didn't make it before (due to timing).

  A few recent regressions are fixed, most importantly in the cpuidle
  menu governor and in the ACPI backlight driver and some x86 platform
  drivers depending on it.

  Some more bugs are fixed and cleanups are made on top of that.

  Specifics:

   - Modify the driver core and the USB subsystem to allow USB devices
     to stay suspended over system suspend/resume cycles if they have
     been runtime-suspended already beforehand and fix some bugs on top

9638685e32 ARM: SoC driver updates for v4.5
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
 
 + Again a bunch of other smaller updates and patches.

4a121096db MAINTAINERS: Update mailing list for Renesas SoC Development
Update the mailing list used for development of support for
Renesas SoCs and related drivers.

Up until now the linux-sh mailing list has been used, however,
Renesas SoCs are now much wider than the SH architecture and there
is some desire from some for the linux-sh list to refocus on
discussion of the work on the SH architecture.

f6a6bbae04 platform/x86: Add Asus Wireless Radio Control driver
Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
separate ACPI device for notifications from the airplane mode hotkey.
This device is called "Wireless Radio Control" in Asus websites and ASHS
in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
above.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
query 0x0B is started in the Embedded Controller, and all this query does
is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):

	Scope (_SB.PCI0.SBRG.EC0)
	{
		(...)
		Method (_Q0B, 0, NotSerialized)  // _Qxx: EC Query
		{
			If ((MSOS () >= OSW8))

				Notify (ASHS, 0x88) // Device-Specific
			}
			Else

58cf279aca GPIO bulk updates for the v4.5 kernel cycle:
Infrastructural changes:
 
 - In struct gpio_chip, rename the .dev node to .parent to better reflect
   the fact that this is not the GPIO struct device abstraction. We will
   add that soon so this would be totallt confusing.
 
 - It was noted that the driver .get_value() callbacks was
   sometimes reporting negative -ERR values to the gpiolib core, expecting
   them to be propagated to consumer gpiod_get_value() and gpio_get_value()
   calls. This was not happening, so as there was a mess of drivers
   returning negative errors and some returning "anything else than zero"
   to indicate that a line was active. As some would have bit 31 set to
   indicate "line active" it clashed with negative error codes. This is
   fixed by the largeish series clamping values in all drivers with
   !!value to [0,1] and then augmenting the code to propagate error codes
   to consumers. (Includes some ACKed patches in other subsystems.)
 
 - Add a void *data pointer to struct gpio_chip. The container_of() design
   pattern is indeed very nice, but we want to reform the struct gpio_chip
   to be a non-volative, stateless business, and keep states internal to
   the gpiolib to be able to hold on to the state when adding a proper
   userspace ABI (character device) further down the road. To achieve this,
   drivers need a handle at the internal state that is not dependent on
   their struct gpio_chip() so we add gpiochip_add_data() and
   gpiochip_get_data() following the pattern of many other subsystems.
   All the "use gpiochip data pointer" patches transforms drivers to this
   scheme.
 
 - The Generic GPIO chip header has been merged into the general
   <linux/gpio/driver.h> header, and the custom header for that removed.
   Instead of having a separate mm_gpio_chip struct for these generic
   drivers, merge that into struct gpio_chip, simplifying the code and
   removing the need for separate and confusing includes.
 
 Misc improvements:
 
 - Stabilize the way GPIOs are looked up from the ACPI legacy
   specification.
 
 - Incremental driver features for PXA, PCA953X, Lantiq (patches from the
   OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
 
 New drivers:
 
 - Add a GPIO chip to the ALSA SoC AC97 driver.
 
 - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but
   the branch is merged here too to account for infrastructural changes).
 
 - The sx150x driver now supports the sx1502.

Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "Here is the bulk of GPIO changes for v4.5.

  Notably there are big refactorings mostly by myself, aimed at getting
  the gpio_chip into a shape that makes me believe I can proceed to
  preserve state for a proper userspace ABI (character device) that has
  already been proposed once, but resulted in the feedback that I need
  to go back and restructure stuff.  So I've been restructuring stuff.
  On the way I ran into brokenness (return code from the get_value()
  callback) and had to fix it.  Also, refactored generic GPIO to be
  simpler.

  Some of that is still waiting to trickle down from the subsystems all
  over the kernel that provide random gpio_chips, I've touched every
  single GPIO driver in the kernel now, oh man I didn't know I was
  responsible for so much...

  Apart from that we're churning along as usual.

  I took some effort to test and retest so it should merge nicely and we
  shook out a couple of bugs in -next.

  Infrastructural changes:

   - In struct gpio_chip, rename the .dev node to .parent to better
     reflect the fact that this is not the GPIO struct device
     abstraction.  We will add that soon so this would be totallt

     specification.

   - Incremental driver features for PXA, PCA953X, Lantiq (patches from
     the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48

  New drivers:

   - Add a GPIO chip to the ALSA SoC AC97 driver.

   - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
     but the branch is merged here too to account for infrastructural
     changes).

   - The sx150x driver now supports the sx1502"

185a383ada x86/PCI: Add driver for Intel Volume Management Device (VMD)
The Intel Volume Management Device (VMD) is a Root Complex Integrated
Endpoint that acts as a host bridge to a secondary PCIe domain.  BIOS can
reassign one or more Root Ports to appear within a VMD domain instead of
the primary domain.  The immediate benefit is that additional PCIe domains
allow more than 256 buses in a system by letting bus numbers be reused
across different domains.

VMD domains do not define ACPI _SEG, so to avoid domain clashing with host
bridges defining this segment, VMD domains start at 0x10000, which is
greater than the highest possible 16-bit ACPI defined _SEG.

This driver enumerates and enables the domain using the root bus
configuration interface provided by the PCI subsystem.  The driver provides
configuration space accessor functions (pci_ops), bus and memory resources,
an MSI IRQ domain with irq_chip implementation, and DMA operations
necessary to use devices through the VMD endpoint's interface.

VMD routes I/O as follows:

   1) Configuration Space: BAR 0 ("CFGBAR") of VMD provides the base
   address and size for configuration space register access to VMD-owned
   root ports.  It works similarly to MMCONFIG for extended configuration
   space.  Bus numbering is independent and does not conflict with the
   primary domain.

   2) MMIO Space: BARs 2 and 4 ("MEMBAR1" and "MEMBAR2") of VMD provide the
   base address, size, and type for MMIO register access.  These addresses
   are not translated by VMD hardware; they are simply reservations to be
   distributed to root ports' memory base/limit registers and subdivided
   among devices downstream.

   3) DMA: To interact appropriately with an IOMMU, the source ID DMA read
   and write requests are translated to the bus-device-function of the VMD
   endpoint.  Otherwise, DMA operates normally without VMD-specific address
   translation.

   4) Interrupts: Part of VMD's BAR 4 is reserved for VMD's MSI-X Table and
   PBA.  MSIs from VMD domain devices and ports are remapped to appear as
   if they were issued using one of VMD's MSI-X table entries.  Each MSI
   and MSI-X address of VMD-owned devices and ports has a special format
   where the address refers to specific entries in the VMD's MSI-X table.
   As with DMA, the interrupt source ID is translated to VMD's
   bus-device-function.

   The driver provides its own MSI and MSI-X configuration functions
   specific to how MSI messages are used within the VMD domain, and
   provides an irq_chip for independent IRQ allocation to relay interrupts
   from VMD's interrupt handler to the appropriate device driver's handler.

   5) Errors: PCIe error message are intercepted by the root ports normally
   (e.g., AER), except with VMD, system errors (i.e., firmware first) are
   disabled by default.  AER and hotplug interrupts are translated in the
   same way as endpoint interrupts.

   6) VMD does not support INTx interrupts or IO ports.  Devices or drivers
   requiring these features should either not be placed below VMD-owned
   root ports, or VMD should be disabled by BIOS for such endpoints.

a13c7c51fd dt-bindings: regulator/clock/mfd: Reorganize S2MPS-family bindings
Bindings for Samsung S2M and S5M family PMICs are in mess. They are
spread over different files and subdirectories in a non-consistent way.
The devices and respective drivers for them share a lot in common so
everything could be organized in a more readable way.

Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the
drivers for this family of devices:
 - move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD
   driver (common for entire family),
 - split clock block to clock/samsung,s2mps11.txt,

67990608c8 Power management and ACPI updates for v4.5-rc1
- Add a debugfs-based interface for interacting with the ACPICA's
    AML debugger introduced in the previous cycle and a new user
    space tool for that, fix some bugs related to the AML debugger
    and clean up the code in question (Lv Zheng, Dan Carpenter,
    Colin Ian King, Markus Elfring).
 
  - Update ACPICA to upstream revision 20151218 including a number
    of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng,
    Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box,
    Rafael Wysocki).
 
    In particular, the previously added erroneous support for the
    _SUB object is dropped, the concatenate operator will support
    all ACPI objects now, the Debug Object handling is improved,
    the SuperName handling of parameters being control methods is
    fixed, the ObjectType operator handling is updated to follow
    ACPI 5.0A and the handling of CondRefOf and RefOf is updated
    accordingly, module-level code will be executed after loading
    each ACPI table now (instead of being run once after all tables
    containing AML have been loaded), the Operation Region handlers
    management is updated to fix some reported problems and a the
    ACPICA code in the kernel is more in line with the upstream
    now.
 
  - Update the ACPI backlight driver to provide information on
    whether or not it will generate key-presses for brightness
    change hotkeys and update some platform drivers (dell-wmi,
    thinkpad_acpi) to use that information to avoid sending double
    key-events to users pace for these, add new ACPI backlight
    quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht).
 
  - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).
 
  - Fix the handling of the list of device IDs of device objects
    found in the ACPI namespace and add a helper for checking if
    there is a device object for a given device ID (Lukas Wunner).
 
  - Change the logic in the ACPI namespace scanning code to create
    struct acpi_device objects for all ACPI device objects found in
    the namespace even if _STA fails for them which helps to avoid
    device enumeration problems on Microsoft Surface 3 (Aaron Lu).
 
  - Add support for the APM X-Gene ACPI I2C device to the ACPI
    driver for AMD SoCs (Loc Ho).
 
  - Fix the long-standing issue with the DMA controller on Intel
    SoCs where ACPI tables have no power management support for
    the DMA controller itself, but it can be powered off automatically
    when the last (other) device on the SoC is powered off via ACPI
    and clean up the ACPI driver for Intel SoCs (acpi-lpss) after
    previous attempts to fix that problem (Andy Shevchenko).
 
  - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King,
    Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki,
    Sinan Kaya).
 
  - Update the device properties framework for better handling of
    built-in properties, add support for built-in properties to
    the platform bus type, update the MFD subsystem's handling
    of device properties and add support for passing default
    configuration data as device properties to the intel-lpss MFD
    drivers, convert the designware I2C driver to use the unified
    device properties API and add a fallback mechanism for using
    default built-in properties if the platform firmware fails
    to provide the properties as expected by drivers (Andy Shevchenko,
    Mika Westerberg, Heikki Krogerus, Andrew Morton).
 
  - Add new Device Tree bindings to the Operating Performance Points
    (OPP) framework and update the exynos4412 DT binding accordingly,
    introduce debugfs support for the OPP framework (Viresh Kumar,
    Bartlomiej Zolnierkiewicz).
 
  - Migrate the mt8173 cpufreq driver to the new OPP bindings
    (Pi-Cheng Chen).
 
  - Update the cpufreq core to make the handling of governors
    more efficient, especially on systems where policy objects
    are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki).
 
  - Fix cpufreq governor handling on configurations with
    CONFIG_HZ_PERIODIC set (Chen Yu).
 
  - Clean up the cpufreq core code related to the boost sysfs knob
    support and update the ACPI cpufreq driver accordingly (Rafael
    Wysocki).
 
  - Add a new cpufreq driver for ST platforms and corresponding
    Device Tree bindings (Lee Jones).
 
  - Update the intel_pstate driver to allow the P-state selection
    algorithm used by it to depend on the CPU ID of the processor it
    is running on, make it use a special P-state selection algorithm
    (with an IO wait time compensation tweak) on Atom CPUs based on
    the Airmont and Silvermont cores so as to reduce their energy
    consumption and improve intel_pstate documentation (Philippe
    Longepe, Srinivas Pandruvada).
 
  - Update the cpufreq-dt driver to support registering cooling
    devices that use the (P * V^2 * f) dynamic power draw formula
    where V is the voltage, f is the frequency and P is a constant
    coefficient provided by Device Tree and update the arm_big_little
    cpufreq driver to use that support (Punit Agrawal).
 
  - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq,
    blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia,
    Jacob Tanenbaum, Markus Elfring).
 
  - cpuidle core tweaks related to polling and measured_us
    calculation (Rik van Riel).
 
  - Removal of modularity from a few cpuidle drivers (clps711x,
    ux500, exynos) that cannot be built as modules in practice
    (Paul Gortmaker).
 
  - PM core update to prevent devices from being probed during
    system suspend/resume which is generally problematic and may
    lead to inconsistent behavior (Grygorii Strashko).
 
  - Assorted updates of the PM core and related code (Julia Lawall,
    Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki,
    Ulf Hansson).
 
  - PNP bus type updates (Christophe Le Roy, Heiner Kallweit).
 
  - PCI PM code cleanups (Jarkko Nikula, Julia Lawall).
 
  - cpupower tool updates (Jacob Tanenbaum, Thomas Renninger).

Merge tag 'pm+acpi-4.5-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull oower management and ACPI updates from Rafael Wysocki:
 "As far as the number of commits goes, ACPICA takes the lead this time,
  followed by cpufreq and the device properties framework changes.

  The most significant new feature is the debugfs-based interface to the
  ACPICA's AML debugger added in the previous cycle and a new user space
  tool for accessing it.

  On the cpufreq front, the core is updated to handle governors more
  efficiently, particularly on systems where a single cpufreq policy
  object is shared between multiple CPUs, and there are quite a few
  changes in drivers (intel_pstate, cpufreq-dt etc).

  The device properties framework is updated to handle built-in (ie
  included in the kernel itself) device properties better, among other
  things by adding a fallback mechanism that will allow drivers to
  provide default properties to be used in case the plaform firmware
  doesn't provide the properties expected by them.

  The Operating Performance Points (OPP) framework gets new DT bindings
  and debugfs support.

  A new cpufreq driver for ST platforms is added and the ACPI driver for
  AMD SoCs will now support the APM X-Gene ACPI I2C device.

  The rest is mostly fixes and cleanups all over.

  Specifics:

   - Add a debugfs-based interface for interacting with the ACPICA's AML
     debugger introduced in the previous cycle and a new user space tool
     for that, fix some bugs related to the AML debugger and clean up
     the code in question (Lv Zheng, Dan Carpenter, Colin Ian King,

   - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King,
     Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki,
     Sinan Kaya).

   - Update the device properties framework for better handling of
     built-in properties, add support for built-in properties to the
     platform bus type, update the MFD subsystem's handling of device
     properties and add support for passing default configuration data
     as device properties to the intel-lpss MFD drivers, convert the
     designware I2C driver to use the unified device properties API and
     add a fallback mechanism for using default built-in properties if
     the platform firmware fails to provide the properties as expected
     by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus,
     Andrew Morton).

   - Add new Device Tree bindings to the Operating Performance Points
     (OPP) framework and update the exynos4412 DT binding accordingly,
     introduce debugfs support for the OPP framework (Viresh Kumar,
     Bartlomiej Zolnierkiewicz).

   - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng
     Chen).

   - Update the cpufreq core to make the handling of governors more
     efficient, especially on systems where policy objects are shared
     between multiple CPUs (Viresh Kumar, Rafael Wysocki).

   - Fix cpufreq governor handling on configurations with
     CONFIG_HZ_PERIODIC set (Chen Yu).

   - Clean up the cpufreq core code related to the boost sysfs knob
     support and update the ACPI cpufreq driver accordingly (Rafael
     Wysocki).

   - Add a new cpufreq driver for ST platforms and corresponding Device
     Tree bindings (Lee Jones).

   - Update the intel_pstate driver to allow the P-state selection
     algorithm used by it to depend on the CPU ID of the processor it is
     running on, make it use a special P-state selection algorithm (with
     an IO wait time compensation tweak) on Atom CPUs based on the
     Airmont and Silvermont cores so as to reduce their energy
     consumption and improve intel_pstate documentation (Philippe
     Longepe, Srinivas Pandruvada).

   - Update the cpufreq-dt driver to support registering cooling devices
     that use the (P * V^2 * f) dynamic power draw formula where V is
     the voltage, f is the frequency and P is a constant coefficient
     provided by Device Tree and update the arm_big_little cpufreq
     driver to use that support (Punit Agrawal).

   - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq,
     blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob
     Tanenbaum, Markus Elfring).

   - cpuidle core tweaks related to polling and measured_us calculation
     (Rik van Riel).

   - Removal of modularity from a few cpuidle drivers (clps711x, ux500,
     exynos) that cannot be built as modules in practice (Paul
     Gortmaker).

   - PM core update to prevent devices from being probed during system
     suspend/resume which is generally problematic and may lead to
     inconsistent behavior (Grygorii Strashko).

   - Assorted updates of the PM core and related code (Julia Lawall,
     Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf
     Hansson).

   - PNP bus type updates (Christophe Le Roy, Heiner Kallweit).

   - PCI PM code cleanups (Jarkko Nikula, Julia Lawall).

   - cpupower tool updates (Jacob Tanenbaum, Thomas Renninger)"

Merge tag 'pinctrl-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control patches for the v4.5 series.

  Notably I have a patch to driver core from Stephen Boyd in the pull
  request, this has been ACKed by Greg so it should be OK.  The internal
  API needed some tweaking to allow modular Qualcomm pin controllers.

  There is a bit of development history in here but it should all add up
  nicely and has boiled in linux-next.  For example I merged in v4.4-rc5
  to get rid of some nasty merge conflicts.

  Summary:

   - New drivers:
      - PXA2xx pin controller support
      - Broadcom NSP pin controller support

   - New subdrivers:
      - Samsung EXYNOS5410 support
      - Qualcomm MSM8996 support
      - Qualcomm PM8994 support
      - Qualcomm PM8994 MPP support
      - Allwinner sunxi H3 support
      - Allwinner sunxi A80 support
      - Rockchip RK3228 support

   - Rename the Cygnus pinctrl driver to "iproc" as it is more generic
     than was originally thought.

   - A bunch of Lantiq/Xway updates especially from the OpenWRT people.

   - Several refactorings for the Super-H SH PFC pin controllers.
     Adding SCIF_CLK support.

   - Several fixes to the Atlas 7 driver.

   - Various fixes all over the place"

This is the first NFC pull request for 4.5 and it brings:
 
 - A new driver for the STMicroelectronics ST95HF NFC chipset.
   The ST95HF is an NFC digital transceiver with an embedded analog
   front-end and as such relies on the Linux NFC digital
   implementation. This is the 3rd user of the NFC digital stack.
 
 - ACPI support for the ST st-nci and st21nfca drivers.
 
 - A small improvement for the nfcsim driver, as we can now tune
   the Rx delay through sysfs.
 
 - A bunch of minor cleanups and small fixes from Christophe Ricard,
   for a few drivers and the NFC core code.

4b7f48d395 bus: uniphier-system-bus: add UniPhier System Bus driver
The UniPhier System Bus is an external bus that connects on-board
devices to the UniPhier SoC.  Each bank (chip select) is dynamically
mapped to the CPU-viewed address base via the bus controller.  The
bus controller must be configured before any access to the bus.

This driver parses the "ranges" property of the System Bus node and
initialized the bus controller.  After the bus becomes ready, devices
below it are populated.

Note:
Each bank can be mapped anywhere in the supported address space;
there is nothing preventing us from assigning bank 0 on 0x42000000,
0x43000000, or anywhere as long as such region is not used by others.
So, the "ranges" is just one possible software configuration, which
does not seem to fit in device tree because device tree is a hardware
description language.  However, of_translate_address() requires
"ranges" in every bus node between CPUs and device mapped on the CPU
address space.  In other words, "ranges" properties must be statically
defined in device tree.  After some discussion, I decided the dynamic
address reassignment by the driver is too bothersome.  Instead, the
device tree should provide a reasonable translation setup that the OS
can rely on.
