This patch moves the NVMe driver from drivers/block/ to its own new
drivers/nvme/host/ directory.  This is in preparation of splitting the
current monolithic driver up and add support for the upcoming NVMe
over Fabrics standard.  The drivers/nvme/host/ is chose to leave space
for a NVMe target implementation in addition to this host side driver.

Azael Avalos 14991fc7df platform/x86: Toshiba WMI Hotkey Driver
Toshiba laptops that feature WMI events for hotkeys were left unsupported
by the toshiba_acpi driver, however, commit a88bc06e5a ("toshiba_acpi:
Avoid registering input device on WMI event laptops") added hardware
support for such laptops, but the hotkeys are not handled there.

This driver adds support for hotkey monitoring on certain Toshiba laptops
that manage the hotkeys via WMI events instead of the Toshiba
Configuration Interface (TCI).

The toshiba_acpi driver and this one can co-exist, as this only takes
care of hotkeys, while the proper takes care of hardware related stuff.

Currently the driver is under the EXPERIMENTAL flag, as the keymap
and the notify function are incomplete (due to lack of hardware to test).

Alex Williamson f73f817312 virt: IRQ bypass manager
When a physical I/O device is assigned to a virtual machine through
facilities like VFIO and KVM, the interrupt for the device generally
bounces through the host system before being injected into the VM.
However, hardware technologies exist that often allow the host to be
bypassed for some of these scenarios.  Intel Posted Interrupts allow
the specified physical edge interrupts to be directly injected into a
guest when delivered to a physical processor while the vCPU is
running.  ARM IRQ Forwarding allows forwarded physical interrupts to
be directly deactivated by the guest.

The IRQ bypass manager here is meant to provide the shim to connect
interrupt producers, generally the host physical device driver, with
interrupt consumers, generally the hypervisor, in order to configure
these bypass mechanism.  To do this, we base the connection on a
shared, opaque token.  For KVM-VFIO this is expected to be an
eventfd_ctx since this is the connection we already use to connect an
eventfd to an irqfd on the in-kernel path.  When a producer and
consumer with matching tokens is found, callbacks via both registered
participants allow the bypass facilities to be automatically enabled.

Stefan Agner 456930d80a mtd: nand: vf610_nfc: Freescale NFC for VF610, MPC5125 and others
This driver supports Freescale NFC (NAND flash controller) found on
Vybrid (VF610), MPC5125, MCF54418 and Kinetis K70. The driver has
been tested using 8-bit and 16-bit NAND interface on the ARM based
Vybrid SoC VF500 and VF610 platform.
parameter page reading.

Limitations:
- Untested on MPC5125 and M54418.
- DMA and pipelining not used.
- 2K pages or less.
- No chip select, one NAND chip per controller.
- No hardware ECC.

Some paths have been hand-optimized and evaluated by measurements
made using mtd_speedtest.ko on a 100MB MTD partition.

opt = hand-optimized by combining multiple accesses into one read/write

The measurements have not been statistically verfied, hence use them

Linus Torvalds ddff42e592 sound fixes for 4.3-rc3
This ended up with a larger set of fixes than wished, unfortunately.
 As diffstat shows, the majority of changes are for various ASoC
 drivers (Realtek, Wolfson codec drivers, etc), in addition to a couple
 of HD-audio regression fixes.  All these are reasonably small and
 nothing to scare much.

Mathieu Desnoyers 5b25b13ab0 sys_membarrier(): system-wide memory barrier (generic, x86)
Here is an implementation of a new system call, sys_membarrier(), which
executes a memory barrier on all threads running on the system.  It is
implemented by calling synchronize_sched().  It can be used to
distribute the cost of user-space memory barriers asymmetrically by
transforming pairs of memory barriers into pairs consisting of
sys_membarrier() and a compiler barrier.  For synchronization primitives
that distinguish between read-side and write-side (e.g.  userspace RCU
[1], rwlocks), the read-side can be accelerated significantly by moving
the bulk of the memory barrier overhead to the write-side.

The existing applications of which I am aware that would be improved by
this system call are as follows:

* Through Userspace RCU library (http://urcu.so)
  - DNS server (Knot DNS) https://www.knot-dns.cz/
  - Network sniffer (http://netsniff-ng.org/)
  - Distributed object storage (https://sheepdog.github.io/sheepdog/)
  - User-space tracing (http://lttng.org)
  - Network storage system (https://www.gluster.org/)
  - Virtual routers (https://events.linuxfoundation.org/sites/events/files/slides/DPDK_RCU_0MQ.pdf)
  - Financial software (https://lkml.org/lkml/2015/3/23/189)

Those projects use RCU in userspace to increase read-side speed and
scalability compared to locking.  Especially in the case of RCU used by
libraries, sys_membarrier can speed up the read-side by moving the bulk of
the memory barrier cost to synchronize_rcu().

* Direct users of sys_membarrier
  - core dotnet garbage collector (https://github.com/dotnet/coreclr/issues/198)

Microsoft core dotnet GC developers are planning to use the mprotect()
side-effect of issuing memory barriers through IPIs as a way to implement
Windows FlushProcessWriteBuffers() on Linux.  They are referring to
sys_membarrier in their github thread, specifically stating that
sys_membarrier() is what they are looking for.

To explain the benefit of this scheme, let's introduce two example threads:

Thread A (non-frequent, e.g. executing liburcu synchronize_rcu())
Thread B (frequent, e.g. executing liburcu
rcu_read_lock()/rcu_read_unlock())

In a scheme where all smp_mb() in thread A are ordering memory accesses
with respect to smp_mb() present in Thread B, we can change each
smp_mb() within Thread A into calls to sys_membarrier() and each
smp_mb() within Thread B into compiler barriers "barrier()".

Before the change, we had, for each smp_mb() pairs:

Thread A                    Thread B
previous mem accesses       previous mem accesses
smp_mb()                    smp_mb()
following mem accesses      following mem accesses

After the change, these pairs become:

Thread A                    Thread B
prev mem accesses           prev mem accesses
sys_membarrier()            barrier()
follow mem accesses         follow mem accesses

As we can see, there are two possible scenarios: either Thread B memory
accesses do not happen concurrently with Thread A accesses (1), or they
do (2).

1) Non-concurrent Thread A vs Thread B accesses:

Thread A                    Thread B
prev mem accesses
sys_membarrier()
follow mem accesses
                            prev mem accesses
                            barrier()
                            follow mem accesses

In this case, thread B accesses will be weakly ordered. This is OK,
because at that point, thread A is not particularly interested in
ordering them with respect to its own accesses.

2) Concurrent Thread A vs Thread B accesses

Thread A                    Thread B
prev mem accesses           prev mem accesses
sys_membarrier()            barrier()
follow mem accesses         follow mem accesses

In this case, thread B accesses, which are ensured to be in program
order thanks to the compiler barrier, will be "upgraded" to full
smp_mb() by synchronize_sched().

* Benchmarks

On Intel Xeon E5405 (8 cores)
(one thread is calling sys_membarrier, the other 7 threads are busy
looping)

1000 non-expedited sys_membarrier calls in 33s =3D 33 milliseconds/call.

* User-space user of this system call: Userspace RCU library

Both the signal-based and the sys_membarrier userspace RCU schemes
permit us to remove the memory barrier from the userspace RCU
rcu_read_lock() and rcu_read_unlock() primitives, thus significantly
accelerating them. These memory barriers are replaced by compiler
barriers on the read-side, and all matching memory barriers on the
write-side are turned into an invocation of a memory barrier on all
active threads in the process. By letting the kernel perform this
synchronization rather than dumbly sending a signal to every process
threads (as we currently do), we diminish the number of unnecessary wake
ups and only issue the memory barriers on active threads. Non-running
threads do not need to execute such barrier anyway, because these are
implied by the scheduler context switches.

Results in liburcu:

Operations in 10s, 6 readers, 2 writers:

memory barriers in reader:    1701557485 reads, 2202847 writes
signal-based scheme:          9830061167 reads,    6700 writes
sys_membarrier:               9952759104 reads,     425 writes
sys_membarrier (dyn. check):  7970328887 reads,     425 writes

The dynamic sys_membarrier availability check adds some overhead to
the read-side compared to the signal-based scheme, but besides that,
sys_membarrier slightly outperforms the signal-based scheme. However,
this non-expedited sys_membarrier implementation has a much slower grace
period than signal and memory barrier schemes.

Besides diminishing the number of wake-ups, one major advantage of the
membarrier system call over the signal-based scheme is that it does not
need to reserve a signal. This plays much more nicely with libraries,
and with processes injected into for tracing purposes, for which we
cannot expect that signals will be unused by the application.

An expedited version of this system call can be added later on to speed
up the grace period. Its implementation will likely depend on reading
the cpu_curr()->mm without holding each CPU's rq lock.

This patch adds the system call to x86 and to asm-generic.

MEMBARRIER(2)              Linux Programmer's Manual             MEMBARRIER(2)

NAME
       membarrier - issue memory barriers on a set of threads

SYNOPSIS
       #include <linux/membarrier.h>

       int membarrier(int cmd, int flags);

DESCRIPTION
       The cmd argument is one of the following:

       MEMBARRIER_CMD_QUERY
              Query  the  set  of  supported commands. It returns a bitmask of
              supported commands.

       MEMBARRIER_CMD_SHARED
              Execute a memory barrier on all threads running on  the  system.
              Upon  return from system call, the caller thread is ensured that
              all running threads have passed through a state where all memory
              accesses  to  user-space  addresses  match program order between
              entry to and return from the system  call  (non-running  threads
              are de facto in such a state). This covers threads from all pro=E2=80=90
              cesses running on the system.  This command returns 0.

       The flags argument needs to be 0. For future extensions.

       All memory accesses performed  in  program  order  from  each  targeted
       thread is guaranteed to be ordered with respect to sys_membarrier(). If
       we use the semantic "barrier()" to represent a compiler barrier forcing
       memory  accesses  to  be performed in program order across the barrier,
       and smp_mb() to represent explicit memory barriers forcing full  memory
       ordering  across  the barrier, we have the following ordering table for
       each pair of barrier(), sys_membarrier() and smp_mb():

       The pair ordering is detailed as (O: ordered, X: not ordered):

                              barrier()   smp_mb() sys_membarrier()
              barrier()          X           X            O
              smp_mb()           X           O            O
              sys_membarrier()   O           O            O

RETURN VALUE
       On success, these system calls return zero.  On error, -1 is  returned,
       and errno is set appropriately. For a given command, with flags
       argument set to 0, this system call is guaranteed to always return the
       same value until reboot.

ERRORS
       ENOSYS System call is not implemented.

       EINVAL Invalid arguments.

Pull inifiniband/rdma updates from Doug Ledford:
 "This is a fairly sizeable set of changes.  I've put them through a
  decent amount of testing prior to sending the pull request due to
  that.

  There are still a few fixups that I know are coming, but I wanted to
  go ahead and get the big, sizable chunk into your hands sooner rather
  than waiting for those last few fixups.

  Of note is the fact that this creates what is intended to be a
  temporary area in the drivers/staging tree specifically for some
  cleanups and additions that are coming for the RDMA stack.  We
  deprecated two drivers (ipath and amso1100) and are waiting to hear
  back if we can deprecate another one (ehca).  We also put Intel's new
  hfi1 driver into this area because it needs to be refactored and a
  transfer library created out of the factored out code, and then it and
  the qib driver and the soft-roce driver should all be modified to use
  that library.

  I expect drivers/staging/rdma to be around for three or four kernel
  releases and then to go away as all of the work is completed and final
  deletions of deprecated drivers are done.

  Summary of changes for 4.3:

   - Create drivers/staging/rdma
   - Move amso1100 driver to staging/rdma and schedule for deletion
   - Move ipath driver to staging/rdma and schedule for deletion
   - Add hfi1 driver to staging/rdma and set TODO for move to regular

   - Initial support for namespaces to be used on RDMA devices
   - Add RoCE GID table handling to the RDMA core caching code

Linus Torvalds 12f03ee606 libnvdimm for 4.3:
1/ Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
    mechanism for adding device-driver-discovered memory regions to the
    kernel's direct map.  This facility is used by the pmem driver to
    enable pfn_to_page() operations on the page frames returned by DAX
    ('direct_access' in 'struct block_device_operations'). For now, the
    'memmap' allocation for these "device" pages comes from "System
    RAM".  Support for allocating the memmap from device memory will
    arrive in a later kernel.
 
 2/ Introduce memremap() to replace usages of ioremap_cache() and
    ioremap_wt().  memremap() drops the __iomem annotation for these
    mappings to memory that do not have i/o side effects.  The
    replacement of ioremap_cache() with memremap() is limited to the
    pmem driver to ease merging the api change in v4.3.  Completion of
    the conversion is targeted for v4.4.
 
 3/ Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
    driver, update the VFS DAX implementation and PMEM api to provide
    persistence guarantees for kernel operations on a DAX mapping.
 
 4/ Convert the ACPI NFIT 'BLK' driver to map the block apertures as
    cacheable to improve performance.
 
 5/ Miscellaneous updates and fixes to libnvdimm including support
    for issuing "address range scrub" commands, clarifying the optimal
    'sector size' of pmem devices, a clarification of the usage of the
    ACPI '_STA' (status) property for DIMM devices, and other minor
    fixes.

Pull libnvdimm updates from Dan Williams:
 "This update has successfully completed a 0day-kbuild run and has
  appeared in a linux-next release.  The changes outside of the typical
  drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the

[ The Kconfig and Makefile entries got re-sorted alphabetically, and I
  handled the conflict with the new Intel integrated IDMA driver by
  slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
  order to keep the Intel entries together.  I think it might be a good
  idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
  the sorting be a true sort, not this mismash.

Linus Torvalds 88a99886c2 This is the bulk of pin control changes for the v4.3 development
cycle
 
 Core changes:
 
 - It is possible configure groups in debugfs.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a
   combined call to irq_set_chained_handler_and_data(). This
   series was created by Thomas Gleixner after the problem was
   observed by Russell King.
 
 - Tglx also made another series of patches switching
   __irq_set_handler_locked() for irq_set_handler_locked() which
   is way cleaner.
 
 - Tglx also wrote a good bunch of patches to make use of
   irq_desc_get_xxx() accessors and avoid looking up irq_descs
   from IRQ numbers. The goal is to get rid of the irq number
   from the handlers in the IRQ flow which is nice.
 
 Driver feature enhancements:
 
 - Power management support for the SiRF SoC Atlas 7.
 
 - Power down support for the Qualcomm driver.
 
 - Intel Cherryview and Baytrail: switch drivers to use raw
   spinlocks in IRQ handlers to play nice with the realtime
   patch set.
 
 - Rework and new modes handling for Qualcomm SPMI-MPP.
 
 - Pinconf power source config for SH PFC.
 
 New drivers and subdrivers:
 
 - A new driver for Conexant Digicolor CX92755.
 
 - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8,
   PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support.
 
 - Reverse-egineered the S/PDIF settings for the Allwinner
   sun4i driver.
 
 - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
 
 - A new Freescale i.mx6ul subdriver.
 
 Cleanup:
 
 - Remove platform data support in a number of SH PFC
   subdrivers.

Linus Torvalds 102178108e ARM: SoC driver updates for v4.3
Some releases this branch is nearly empty, others we have more stuff. It
 tends to gather drivers that need SoC modification or dependencies such
 that they have to (also) go in through our tree.
 
 For this release, we have merged in part of the reset controller tree
 (with handshake that the parts we have merged in will remain stable),
 as well as dependencies on a few clock branches.
 
 In general, new items here are:
 
 - Qualcomm driver for SMM/SMD, which is how they communicate with the
   coprocessors on (some) of their platforms
 - Memory controller work for ARM's PL172 memory controller
 - Reset drivers for various platforms
 - PMU power domain support for Marvell platforms
 - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support

Linus Torvalds c5fc249862 ARM: SoC cleanups for v4.3
A large cleanup branch this release, with a healthy 10k negative line delta.
 
 Most of this is removal of legacy (non-DT) support of shmobile
 platforms. There is also removal of two non-DT platforms on OMAP,
 and the plat-samsung directory is cleaned out by moving most of the
 previously shared-location-but-not-actually-shared files from there to
 the appropriate mach directories instead.
 
 There are other sets of changes in here as well:
 
  - Rob Herring removed use of set_irq_flags under all platforms and
    moved to genirq alternatives
  - A series of timer API conversions to set-state interface
  - ep93xx, nomadik and ux500 cleanups from Linus Walleij
  - __init annotation fixes from Nicolas Pitre
  + a bunch of other changes that all add up to a nice set of cleanups

 "The main RCU changes in this cycle are:

     otherwise result.

   - privatize smp_mb__after_unlock_lock().

     kernel/rcu/tree.h, in recognition of the fact that RCU is the only
     thing using this, that nothing else is likely to use it, and that
     it is likely to go away completely.

Here is the big staging driver updates for 4.3-rc1.
 
 Lots of things all over the place, almost all of them trivial fixups and
 changes.  The usual IIO updates and new drivers and we have added the
 MOST driver subsystem which is getting cleaned up in the tree.  The
 ozwpan driver is finally being deleted as it is obviously abandoned and
 no one cares about it.
 
 Full details are in the shortlog, and all of these have been in
 linux-next with no reported issues.

It is now time for the ipath driver to begin to be phased out of the kernel.
This patch moves the ipath driver from the Infiniband sub tree to the staging

Doug Ledford 2dfcad3ade Staging: Add staging/rdma directory and update MAINTAINERS
Create the rdma directory in the staging area for use as we deprecate
some older drivers and as we bring in some new drivers that are in
need of work.  Update the MAINTAINERS file so that updates to these
files go to linux-rdma@vger.kernel.org.  Expected lifespan of this
directory is three releases for any deprecated drivers moved here
and an unknown, but theoretically bounded amount of time for the new
drivers as a new core RDMA transfer library needs to be written and
the drivers modified to use it in order for them to move out of this
directory.

Crt Mori 764589b688 iio: mlx90614: Implement filter configuration
Implemented Low pass 3db frequency filter which configures
FIR and IIR values within the configuration register of EEPROM.
For more standardized interface we have fixed the FIR value
to 1024, while changes in IIR value are directly connected to
filter responses. The new datasheet version will provide a
simplified table (also in reStructured text format below) with
this change, to provide quick overview of possible settings.

Below sensor timings (bandwidth) are calculated for 3db frequency
low pass filter.

Chen Yu 2508a45a92 surface pro 3: Add support driver for Surface Pro 3 buttons
Since Surface Pro 3 does not follow the specs of "Windows ACPI Design
Guide for SoC Platform", code in drivers/input/misc/soc_array.c can
not detect these buttons on it. According to bios implementation,
Surface Pro 3 encapsulates these buttons in a device named "VGBI",
with _HID "MSHW0028". When any of the buttons is pressed, a specify
ACPI notification code for this button will be delivered to "VGBI". For
example, if power button is pressed down, ACPI notification code of 0xc6
will be sent by Notify(VGBI, 0xc6).

This patch leverages "VGBI" to distinguish different ACPI notification
code from Power button, Home button, Volume button, then dispatches these
code to input layer. Lid is already covered by acpi button driver, so
there's no need to rewrite.

Lars-Peter Clausen 0e3b67b348 dmaengine: Add support for the Analog Devices AXI-DMAC DMA controller
Add support for the Analog Devices AXI-DMAC DMA controller. This controller
is a soft peripheral that can be instantiated in a FPGA and is often used
in Analog Devices' reference designs for FPGA platforms.

The peripheral has various configuration options that can be selected at
synthesis time and influence the supported features of the instantiated
peripheral, those options are represented as device-tree properties to
allow the driver to behave accordingly.

The peripheral has a zero latency architecture, which means it is possible
to switch from one to the next descriptor without any delay. This is
archived by having a internal queue which can hold multiple descriptors.
The driver supports this, which means it will submit new descriptors
directly to the hardware until the queue is full and not wait for a
descriptor to complete before the next one is submitted. Interrupts are
used for the descriptor queue flow control.

Currently the driver supports SG, cyclic and interleaved slave DMA.

Ingo Molnar 9b9412dc70 Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU changes from Paul E. McKenney:

  - The combination of tree geometry-initialization simplifications
    and OS-jitter-reduction changes to expedited grace periods.
    These two are stacked due to the large number of conflicts
    that would otherwise result.

    [ With one addition, a temporary commit to silence a lockdep false
      positive. Additional changes to the expedited grace-period
      primitives (queued for 4.4) remove the cause of this false
      positive, and therefore include a revert of this temporary commit. ]

  - Documentation updates.

  - Torture-test updates.

  - Miscellaneous fixes.
