      Pull networking updates from David Miller:
      
       1) New offloading infrastructure and example 'rocker' driver for
          offloading of switching and routing to hardware.
      
          This work was done by a large group of dedicated individuals, not
          limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend,
          Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu
      
       2) Start making the networking operate on IOV iterators instead of
          modifying iov objects in-situ during transfers.  Thanks to Al Viro
          and Herbert Xu.
      
       3) A set of new netlink interfaces for the TIPC stack, from Richard
          Alpe.
      
       4) Remove unnecessary looping during ipv6 routing lookups, from Martin
          KaFai Lau.
      
       5) Add PAUSE frame generation support to gianfar driver, from Matei
          Pavaluca.
      
       6) Allow for larger reordering levels in TCP, which are easily
          achievable in the real world right now, from Eric Dumazet.
      
       7) Add a variable of napi_schedule that doesn't need to disable cpu
          interrupts, from Eric Dumazet.
      
       8) Use a doubly linked list to optimize neigh_parms_release(), from
          Nicolas Dichtel.
      
       9) Various enhancements to the kernel BPF verifier, and allow eBPF
          programs to actually be attached to sockets.  From Alexei
          Starovoitov.
      
      10) Support TSO/LSO in sunvnet driver, from David L Stevens.
      
      11) Allow controlling ECN usage via routing metrics, from Florian
          Westphal.
      
      12) Remote checksum offload, from Tom Herbert.
      
      13) Add split-header receive, BQL, and xmit_more support to amd-xgbe
          driver, from Thomas Lendacky.
      
      14) Add MPLS support to openvswitch, from Simon Horman.

          Klassert.
      
      16) Do gro flushes on a per-device basis using a timer, from Eric
          Dumazet.  This tries to resolve the conflicting goals between the
          desired handling of bulk vs.  RPC-like traffic.
      
      17) Allow userspace to ask for the CPU upon what a packet was
          received/steered, via SO_INCOMING_CPU.  From Eric Dumazet.
      
      18) Limit GSO packets to half the current congestion window, from Eric

      Pull sound updates from Takashi Iwai:
       "This became a fairly large pull request.  In addition to the usual
        driver updates / fixes, there have been a high amount of cleanups in
        ASoC area, as well as control API helpers and kernel documentations
        fixes touching through the whole tree.
      
        In the driver side, the biggest changes are the support for new Intel
        SoC found on new x86 machines, and the updates of FireWire dice and
        oxfw drivers.
      
        Some remarkable items are below:
      
        ALSA core:
         - PCM mmap code cleanup, removal of arch-dependent codes
         - PCM xrun injection support
         - PCM hwptr tracepoint support
         - Refactoring of snd_pcm_action(), simplification of PCM locking
         - Robustified sequecner auto-load functionality
         - New control API helpers and lots of cleanups along with them
         - Lots of kerneldoc fixes and cleanups
      
        USB-audio:
         - The mixer resume code was largely rewritten, and the devices with
           quirks are resumed properly.
         - New hardware support: Focusrite Scarlett, Digidesign Mbox1,
           Denon/Marantz DACs, Zoom R16/24
      
        FireWire:
         - DICE driver updates with better duplex and sync support, including
           MIDI support
         - New OXFW driver for Oxford Semiconductor FW970/971 chipset,
           including the previous LaCie Speakers device.  Fullduplex and MIDI
           support included as well as DICE driver.
      
        HD-audio:
         - Refactoring the driver-caps quirk handling in snd-hda-intel
         - More consistent control names representing the topology better
         - Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic
           fix, ASUS Z99He laptop EAPD
      
        ASoC:
         - Conversion of AC'97 drivers to use regmap, bringing us closer to
           the removal of the ASoC level I/O code
         - Clean up a lot of old drivers that were open coding things that
           have subsequently been implemented in the core
         - Some DAPM performance improvements
         - Removal of the now seldom used CODEC mutex
         - Lots of updates for the newer Intel SoC support, including support
           for the DSP and some Cherrytrail and Braswell machine drivers
         - Support for Samsung boards using rt5631 as the CODEC
         - Removal of the obsolete AFEB9260 machine driver
         - Driver support for the TI TS3A227E headset driver used in some
           Chrombeooks
      
        Others:
         - ASIHPI driver update and cleanups
         - Lots of dev_*() printk conversions
         - Lots of trivial cleanups for the codes spotted by Coccinelle"

      Pull devicetree changes from Grant Likely:
       "Lots of activity in the devicetree code for v3.18.  Most of it is
        related to getting all of the overlay support code in place, but there
        are other important things in there.
      
        Highlights:
      
         - OF_RECONFIG notifiers for SPI, I2C and Platform devices.  Those
           subsystems can now respond to live changes to the device tree.
      
         - CONFIG_OF_OVERLAY method for applying live changes to the device
           tree
      
         - Removal of the of_allnodes list.  This used to be used to iterate
           over all the nodes in the device tree, but it is unnecessary
           because the same thing can be done by iterating over the list of
           child pointers.  Getting rid of of_allnodes saves some memory and
           avoids the possibility of of_allnodes being sorted differently from
           the child lists.
      
         - Support for retrieving original DTB blob via sysfs.  Needed by
           kexec.
      
         - More unittests
      
         - Documentation and minor bug fixes"

      Fix race condition between vxlan_sock_add and vxlan_sock_release · 00c83b01
      Marcelo Leitner authored
      
      
      Currently, when trying to reuse a socket, vxlan_sock_add will grab
      vn->sock_lock, locate a reusable socket, inc refcount and release
      vn->sock_lock.
      
      But vxlan_sock_release() will first decrement refcount, and then grab
      that lock. refcnt operations are atomic but as currently we have
      deferred works which hold vs->refcnt each, this might happen, leading to
      a use after free (specially after vxlan_igmp_leave):
      
        CPU 1                            CPU 2

                                         vs = vxlan_find_sock();

      ====================
      mlx4 driver update
      
      This series from Matan, Jenny, Dotan and myself is mostly about adding
      support to a new performance optimized flow steering mode (patches 4-10).
      
      The 1st two patches are small fixes (one for VXLAN and one for SRIOV),
      and the third patch is a fix to avoid hard-lockup situation when many
      (hunderds) processes holding user-space QPs/CQs get events.

      net/mlx4: Add support for A0 steering · 7d077cd3
      Matan Barak authored
      
      
      Add the required firmware commands for A0 steering and a way to enable
      that. The firmware support focuses on INIT_HCA, QUERY_HCA, QUERY_PORT,
      QUERY_DEV_CAP and QUERY_FUNC_CAP commands. Those commands are used
      to configure and query the device.
      
      The different A0 DMFS (steering) modes are:
      
      Static - optimized performance, but flow steering rules are
      limited. This mode should be choosed explicitly by the user
      in order to be used.
      
      Dynamic - this mode should be explicitly choosed by the user.
      In this mode, the FW works in optimized steering mode as long as
      it can and afterwards automatically drops to classic (full) DMFS.
      
      Disable - this mode should be explicitly choosed by the user.
      The user instructs the system not to use optimized steering, even if
      the FW supports Dynamic A0 DMFS (and thus will be able to use optimized
      steering in Default A0 DMFS mode).
      
      Default - this mode is implicitly choosed. In this mode, if the FW
      supports Dynamic A0 DMFS, it'll work in this mode. Otherwise, it'll
      work at Disable A0 DMFS mode.
      
      Under SRIOV configuration, when the A0 steering mode is enabled,
      older guest VF drivers who aren't using the RX QP allocation flag
      (MLX4_RESERVE_A0_QP) will get a QP from the general range and
      fail when attempting to register a steering rule. To avoid that,
      the PF context behaviour is changed once on A0 static mode, to
      require support for the allocation flag in VF drivers too.
      
      In order to enable A0 steering, we use log_num_mgm_entry_size param.
      If the value of the parameter is not positive, we treat the absolute
      value of log_num_mgm_entry_size as a bit field. Setting bit 2 of this
      bit field enables static A0 steering.

      net/mlx4: Add A0 hybrid steering · d57febe1
      Matan Barak authored
      
      
      A0 hybrid steering is a form of high performance flow steering.
      By using this mode, mlx4 cards use a fast limited table based steering,
      in order to enable fast steering of unicast packets to a QP.
      
      In order to implement A0 hybrid steering we allocate resources
      from different zones:
      (1) General range
      (2) Special MAC-assigned QPs [RSS, Raw-Ethernet] each has its own region.
      
      When we create a rss QP or a raw ethernet (A0 steerable and BF ready) QP,
      we try hard to allocate the QP from range (2). Otherwise, we try hard not
      to allocate from this  range. However, when the system is pushed to its
      limits and one needs every resource, the allocator uses every region it can.
      
      Meaning, when we run out of raw-eth qps, the allocator allocates from the
      general range (and the special-A0 area is no longer active). If we run out
      of RSS qps, the mechanism tries to allocate from the raw-eth QP zone. If that
      is also exhausted, the allocator will allocate from the general range
      (and the A0 region is no longer active).
      
      Note that if a raw-eth qp is allocated from the general range, it attempts
      to allocate the range such that bits 6 and 7 (blueflame bits) in the
      QP number are not set.
      
      When the feature is used in SRIOV, the VF has to notify the PF what
      kind of QP attributes it needs. In order to do that, along with the
      "Eth QP blueflame" bit, we reserve a new "A0 steerable QP". According
      to the combination of these bits, the PF tries to allocate a suitable QP.
      
      In order to maintain backward compatibility (with older PFs), the PF
      notifies which QP attributes it supports via QUERY_FUNC_CAP command.

      The zone allocator is a mechanism which manages a few mlx4_bitmaps.
      
      When allocating a resource, the user indicates the desired zone of
      which this resource will be allocated from. If possible, the resource
      will be allocated from this zone. Otherwise, the resource will be
      allocated from a less-than, equal-to, higher-than priority zone,
      according to the desired zone's properties with that respective
      allocation order.

      net/mlx4: Change QP allocation scheme · ddae0349
      Eugenia Emantayev authored
      
      
      When using BF (Blue-Flame), the QPN overrides the VLAN, CV, and SV fields
      in the WQE. Thus, BF may only be used for QPNs with bits 6,7 unset.
      
      The current Ethernet driver code reserves a Tx QP range with 256b alignment.
      
      This is wrong because if there are more than 64 Tx QPs in use,
      QPNs >= base + 65 will have bits 6/7 set.
      
      This problem is not specific for the Ethernet driver, any entity that
      tries to reserve more than 64 BF-enabled QPs should fail. Also, using
      ranges is not necessary here and is wasteful.
      
      The new mechanism introduced here will support reservation for
      "Eth QPs eligible for BF" for all drivers: bare-metal, multi-PF, and VFs
      (when hypervisors support WC in VMs). The flow we use is:
      
      1. In mlx4_en, allocate Tx QPs one by one instead of a range allocation,
         and request "BF enabled QPs" if BF is supported for the function
      
      2. In the ALLOC_RES FW command, change param1 to:
      a. param1[23:0]  - number of QPs
      b. param1[31-24] - flags controlling QPs reservation
      
      Bit 31 refers to Eth blueflame supported QPs. Those QPs must have
      bits 6 and 7 unset in order to be used in Ethernet.
      
      Bits 24-30 of the flags are currently reserved.
      
      When a function tries to allocate a QP, it states the required attributes
      for this QP. Those attributes are considered "best-effort". If an attribute,
      such as Ethernet BF enabled QP, is a must-have attribute, the function has
      to check that attribute is supported before trying to do the allocation.
      
      In a lower layer of the code, mlx4_qp_reserve_range masks out the bits
      which are unsupported. If SRIOV is used, the PF validates those attributes
      and masks out unsupported attributes as well. In order to notify VFs which
      attributes are supported, the VF uses QUERY_FUNC_CAP command. This command's
      mailbox is filled by the PF, which notifies which QP allocation attributes
      it supports.

      net/mlx4_core: Use tasklet for user-space CQ completion events · 3dca0f42
      Matan Barak authored
      
      
      Previously, we've fired all our completion callbacks straight from our ISR.
      
      Some of those callbacks were lightweight (for example, mlx4_en's and
      IPoIB napi callbacks), but some of them did more work (for example,
      the user-space RDMA stack uverbs' completion handler). Besides that,
      doing more than the minimal work in ISR is generally considered wrong,
      it could even lead to a hard lockup of the system. Since when a lot
      of completion events are generated by the hardware, the loop over those
      events could be so long, that we'll get into a hard lockup by the system
      watchdog.
      
      In order to avoid that, add a new way of invoking completion events
      callbacks. In the interrupt itself, we add the CQs which receive completion
      event to a per-EQ list and schedule a tasklet. In the tasklet context
      we loop over all the CQs in the list and invoke the user callback.

      The encapsulated offload flags shouldn't be unconditionally exported
      to the stack. The stack expects offloading to work across all tunnel
      types when those flags are set. This would break other tunnels (like
      GRE) since be2net currently supports tunnel offload for VxLAN only.
      
      Also, with VxLANs Skyhawk-R can offload only 1 UDP dport. If more
      than 1 UDP port is added, we should disable offloads in that case too.

      cxgb4/csiostor: Don't use MASTER_MUST for fw_hello call · 666224d4
      Hariprasad Shenai authored
      
      
      Remove use of calls into t4_fw_hello() with MASTER_MUST, which results in
      FW_HELLO_CMD_MASTERFORCE being set. The firmware doesn't support this and of
      course any existing PF Drivers will totally go for a toss.

      Pull ACPI and power management updates from Rafael Wysocki:
       "This time we have some more new material than we used to have during
        the last couple of development cycles.
      
        The most important part of it to me is the introduction of a unified
        interface for accessing device properties provided by platform
        firmware.  It works with Device Trees and ACPI in a uniform way and
        drivers using it need not worry about where the properties come from
        as long as the platform firmware (either DT or ACPI) makes them
        available.  It covers both devices and "bare" device node objects
        without struct device representation as that turns out to be necessary
        in some cases.  This has been in the works for quite a few months (and
        development cycles) and has been approved by all of the relevant
        maintainers.
      
        On top of that, some drivers are switched over to the new interface
        (at25, leds-gpio, gpio_keys_polled) and some additional changes are
        made to the core GPIO subsystem to allow device drivers to manipulate
        GPIOs in the "canonical" way on platforms that provide GPIO
        information in their ACPI tables, but don't assign names to GPIO lines
        (in which case the driver needs to do that on the basis of what it
        knows about the device in question).  That also has been approved by
        the GPIO core maintainers and the rfkill driver is now going to use
        it.
      
        Second is support for hardware P-states in the intel_pstate driver.
        It uses CPUID to detect whether or not the feature is supported by the
        processor in which case it will be enabled by default.  However, it
        can be disabled entirely from the kernel command line if necessary.
      
        Next is support for a platform firmware interface based on ACPI
        operation regions used by the PMIC (Power Management Integrated
        Circuit) chips on the Intel Baytrail-T and Baytrail-T-CR platforms.
        That interface is used for manipulating power resources and for
        thermal management: sensor temperature reporting, trip point setting
        and so on.
      
        Also the ACPI core is now going to support the _DEP configuration
        information in a limited way.  Basically, _DEP it supposed to reflect
        off-the-hierarchy dependencies between devices which may be very
        indirect, like when AML for one device accesses locations in an
        operation region handled by another device's driver (usually, the
        device depended on this way is a serial bus or GPIO controller).  The
        support added this time is sufficient to make the ACPI battery driver
        work on Asus T100A, but it is general enough to be able to cover some
        other use cases in the future.
      
        Finally, we have a new cpufreq driver for the Loongson1B processor.
      
        In addition to the above, there are fixes and cleanups all over the
        place as usual and a traditional ACPICA update to a recent upstream
        release.
      
        As far as the fixes go, the ACPI LPSS (Low-power Subsystem) driver for
        Intel platforms should be able to handle power management of the DMA
        engine correctly, the cpufreq-dt driver should interact with the
        thermal subsystem in a better way and the ACPI backlight driver should
        handle some more corner cases, among other things.
      
        On top of the ACPICA update there are fixes for race conditions in the
        ACPICA's interrupt handling code which might lead to some random and
        strange looking failures on some systems.
      
        In the cleanups department the most visible part is the series of
        commits targeted at getting rid of the CONFIG_PM_RUNTIME configuration
        option.  That was triggered by a discussion regarding the generic
        power domains code during which we realized that trying to support
        certain combinations of PM config options was painful and not really
        worth it, because nobody would use them in production anyway.  For
        this reason, we decided to make CONFIG_PM_SLEEP select
        CONFIG_PM_RUNTIME and that lead to the conclusion that the latter
        became redundant and CONFIG_PM could be used instead of it.  The
        material here makes that replacement in a major part of the tree, but
        there will be at least one more batch of that in the second part of
        the merge window.
      
        Specifics:
      
         - Support for retrieving device properties information from ACPI _DSD
           device configuration objects and a unified device properties
           interface for device drivers (and subsystems) on top of that.  As
           stated above, this works with Device Trees and ACPI and allows
           device drivers to be written in a platform firmware (DT or ACPI)
           agnostic way.  The at25, leds-gpio and gpio_keys_polled drivers are
           now going to use this new interface and the GPIO subsystem is
           additionally modified to allow device drivers to assign names to
           GPIO resources returned by ACPI _CRS objects (in case _DSD is not
           present or does not provide the expected data).  The changes in
           this set are mostly from Mika Westerberg, Rafael J Wysocki, Aaron
           Lu, and Darren Hart with some fixes from others (Fabio Estevam,
           Geert Uytterhoeven).
      
         - Support for Hardware Managed Performance States (HWP) as described
           in Volume 3, section 14.4, of the Intel SDM in the intel_pstate
           driver.  CPUID is used to detect whether or not the feature is
           supported by the processor.  If supported, it will be enabled
           automatically unless the intel_pstate=no_hwp switch is present in
           the kernel command line.  From Dirk Brandewie.
      
         - New Intel Broadwell-H ID for intel_pstate (Dirk Brandewie).
      
         - Support for firmware interface based on ACPI operation regions used
           by the PMIC chips on the Intel Baytrail-T and Baytrail-T-CR
           platforms for power resource control and thermal management (Aaron
           Lu).
      
         - Limited support for retrieving off-the-hierarchy dependencies
           between devices from ACPI _DEP device configuration objects and
           deferred probing support for the ACPI battery driver based on the
           _DEP information to make that driver work on Asus T100A (Lan
           Tianyu).
      
         - New cpufreq driver for the Loongson1B processor (Kelvin Cheung).
      
         - ACPICA update to upstream revision 20141107 which only affects
           tools (Bob Moore).
      
         - Fixes for race conditions in the ACPICA's interrupt handling code
           and in the ACPI code related to system suspend and resume (Lv Zheng
           and Rafael J Wysocki).
      
         - ACPI core fix for an RCU-related issue in the ioremap() regions
           management code that slowed down significantly after CPUs had been
           allowed to enter idle states even if they'd had RCU callbakcs
           queued and triggered some problems in certain proprietary graphics
           driver (and elsewhere).  The fix replaces synchronize_rcu() in that
           code with synchronize_rcu_expedited() which makes the issue go
           away.  From Konstantin Khlebnikov.
      
         - ACPI LPSS (Low-Power Subsystem) driver fix to handle power
           management of the DMA engine included into the LPSS correctly.  The
           problem is that the DMA engine doesn't have ACPI PM support of its
           own and it simply is turned off when the last LPSS device having
           ACPI PM support goes into D3cold.  To work around that, the PM
           domain used by the ACPI LPSS driver is redesigned so at least one
           device with ACPI PM support will be on as long as the DMA engine is
           in use.  From Andy Shevchenko.
      
         - ACPI backlight driver fix to avoid using it on "Win8-compatible"
           systems where it doesn't work and where it was used by default by
           mistake (Aaron Lu).
      
         - Assorted minor ACPI core fixes and cleanups from Tomasz Nowicki,
           Sudeep Holla, Huang Rui, Hanjun Guo, Fabian Frederick, and Ashwin
           Chaugule (mostly related to the upcoming ARM64 support).
      
         - Intel RAPL (Running Average Power Limit) power capping driver fixes
           and improvements including new processor IDs (Jacob Pan).
      
         - Generic power domains modification to power up domains after
           attaching devices to them to meet the expectations of device
           drivers and bus types assuming devices to be accessible at probe
           time (Ulf Hansson).
      
         - Preliminary support for controlling device clocks from the generic
           power domains core code and modifications of the ARM/shmobile
           platform to use that feature (Ulf Hansson).
      
         - Assorted minor fixes and cleanups of the generic power domains core
           code (Ulf Hansson, Geert Uytterhoeven).
      
         - Assorted minor fixes and cleanups of the device clocks control code
           in the PM core (Geert Uytterhoeven, Grygorii Strashko).
      
         - Consolidation of device power management Kconfig options by making
           CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and removing the latter
           which is now redundant (Rafael J Wysocki and Kevin Hilman).  That
           is the first batch of the changes needed for this purpose.
      
         - Core device runtime power management support code cleanup related
           to the execution of callbacks (Andrzej Hajda).
      
         - cpuidle ARM support improvements (Lorenzo Pieralisi).
      
         - cpuidle cleanup related to the CPUIDLE_FLAG_TIME_VALID flag and a
           new MAINTAINERS entry for ARM Exynos cpuidle (Daniel Lezcano and
           Bartlomiej Zolnierkiewicz).
      
         - New cpufreq driver callback (->ready) to be executed when the
           cpufreq core is ready to use a given policy object and cpufreq-dt
           driver modification to use that callback for cooling device
           registration (Viresh Kumar).
      
         - cpufreq core fixes and cleanups (Viresh Kumar, Vince Hsu, James
           Geboski, Tomeu Vizoso).
      
         - Assorted fixes and cleanups in the cpufreq-pcc, intel_pstate,
           cpufreq-dt, pxa2xx cpufreq drivers (Lenny Szubowicz, Ethan Zhao,
           Stefan Wahren, Petr Cvek).
      
         - OPP (Operating Performance Points) framework modification to allow
           OPPs to be removed too and update of a few cpufreq drivers
           (cpufreq-dt, exynos5440, imx6q, cpufreq) to remove OPPs (added
           during initialization) on driver removal (Viresh Kumar).
      
         - Hibernation core fixes and cleanups (Tina Ruchandani and Markus
           Elfring).
      
         - PM Kconfig fix related to CPU power management (Pankaj Dubey).
      
         - cpupower tool fix (Prarit Bhargava)"
