      ====================
      Intel Wired LAN Driver Updates 2015-04-14
      
      This series contains updates to i40e and i40evf.
      
      Mitch provides a fix for i40e, where VFs were gone and the associated
      VSI's had been removed and the rings were not stopped, which in some
      circumstances cased memory corruption or DMAR errors.  So stop all the
      rings associated with each VF before releasing its resources.  Also
      cleaned up a poorly indented piece of code.  Fixes VF link state, where
      VF devices were assuming link is up unless told otherwise, which means
      that VFs instantiated on a PF with no link, would report the wrong state.
      
      Anjali adds support to add Flow director Sideband rules for a VF from it's
      PF.  Fixes a recently discovered hardware issue, where after a VFLR
      hardware might be indicating to us a reset completion little too early, so
      wait another 10 msec for cache to be cleaned up.
      
      Jesse enables the user to dump the internal hardware state for better
      debugging by allowing a bash script to acquire information about the
      internal hardware state.  The data output to the kernel log is collected
      by the script and can then be sent to Intel.  Also fixed a possible
      failure path to allocate memory that was found by smatch.  Cleaned up
      unused local variables.

      bnx2x: Fix busy_poll vs netpoll · 074975d0
      Eric Dumazet authored
      Commit 9a2620c8 ("bnx2x: prevent WARN during driver unload")
      switched the napi/busy_lock locking mechanism from spin_lock() into
      spin_lock_bh(), breaking inter-operability with netconsole, as netpoll
      disables interrupts prior to calling our napi mechanism.
      
      This switches the driver into using atomic assignments instead of the
      spinlock mechanisms previously employed.
      
      Based on initial patch from Yuval Mintz & Ariel Elior
      
      I basically added softirq starvation avoidance, and mixture
      of atomic operations, plain writes and barriers.
      
      Note this slightly reduces the overhead for this driver when no
      busy_poll sockets are in use.

      net: hip04: Make tx coalesce timer actually work · 48b63776
      Thomas Gleixner authored
      The code sets the expiry value of the timer to a relative value and
      starts it with hrtimer_start_expires. That's fine, but that only works
      once. The timer is started in relative mode, so the expiry value gets
      overwritten with the absolut expiry time (now + expiry).
      
      So once the timer expired, a new call to hrtimer_start_expires results
      in an immidiately expired timer, because the expiry value is
      already in the past.
      
      Use the proper mechanisms to (re)start the timer in the intended way.

       1) Add BQL support to via-rhine, from Tino Reichardt.
      
       2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers
          can support hw switch offloading.  From Floria Fainelli.
      
       3) Allow 'ip address' commands to initiate multicast group join/leave,
          from Madhu Challa.
      
       4) Many ipv4 FIB lookup optimizations from Alexander Duyck.
      
       5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel
          Borkmann.
      
       6) Remove the ugly compat support in ARP for ugly layers like ax25,
          rose, etc.  And use this to clean up the neigh layer, then use it to
          implement MPLS support.  All from Eric Biederman.
      
       7) Support L3 forwarding offloading in switches, from Scott Feldman.
      
       8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed
          up route lookups even further.  From Alexander Duyck.
      
       9) Many improvements and bug fixes to the rhashtable implementation,
          from Herbert Xu and Thomas Graf.  In particular, in the case where
          an rhashtable user bulk adds a large number of items into an empty
          table, we expand the table much more sanely.
      
      10) Don't make the tcp_metrics hash table per-namespace, from Eric
          Biederman.
      
      11) Extend EBPF to access SKB fields, from Alexei Starovoitov.
      
      12) Split out new connection request sockets so that they can be
          established in the main hash table.  Much less false sharing since
          hash lookups go direct to the request sockets instead of having to
          go first to the listener then to the request socks hashed
          underneath.  From Eric Dumazet.
      
      13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.
      
      14) Support stable privacy address generation for RFC7217 in IPV6.  From
          Hannes Frederic Sowa.
      
      15) Hash network namespace into IP frag IDs, also from Hannes Frederic
          Sowa.

      Pull ARM updates from Russell King:
       "Included in this update are both some long term fixes and some new
        features.
      
        Fixes:
      
         - An integer overflow in the calculation of ELF_ET_DYN_BASE.
      
         - Avoiding OOMs for high-order IOMMU allocations
      
         - SMP requires the data cache to be enabled for synchronisation
           primitives to work, so prevent the CPU_DCACHE_DISABLE option being
           visible on SMP builds.
      
         - A bug going back 10+ years in the noMMU ARM94* CPU support code,
           where it corrupts registers.  Found by folk getting Linux running
           on their cameras.
      
         - Versatile Express needs an errata workaround enabled for CPU
           hot-unplug to work.
      
        Features:
      
         - Clean up module linker by handling out of range relocations
           separately from relocation cases we don't handle.
      
         - Fix a long term bug in the pci_mmap_page_range() code, which we
           hope won't impact userspace (we hope there's no users of the
           existing broken interface.)
      
         - Don't map DMA coherent allocations when we don't have a MMU.
      
         - Drop experimental status for SMP_ON_UP.
      
         - Warn when DT doesn't specify ePAPR mandatory cache properties.
      
         - Add documentation concerning how we find the start of physical
           memory for AUTO_ZRELADDR kernels, detailing why we have chosen the
           mask and the implications of changing it.
      
         - Updates from Ard Biesheuvel to address some issues with large
           kernels (such as allyesconfig) failing to link.
      
         - Allow hibernation to work on modern (ARMv7) CPUs - this appears to
           have never worked in the past on these CPUs.
      
         - Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output
           format (hopefully without userspace breaking...  let's hope that if
           it causes someone a problem, they tell us.)
      
         - Fix tegra-ahb DT offsets.
      
         - Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/
           flush_dcache_all()) code to be more efficient, and enable this
           errata workaround by default for ARMv7+SMP CPUs.  This complements
           the Versatile Express fix above.
      
         - Rework ARMv7 context code for errata 430973, so that only Cortex A8
           CPUs are impacted by the branch target buffer flush when this
           errata is enabled.  Also update the help text to indicate that all
           r1p* A8 CPUs are impacted.
      
         - Switch ARM to the generic show_mem() implementation, it conveys all
           the information which we were already reporting.
      
         - Prevent slow timer sources being used for udelay() - timers running
           at less than 1MHz are not useful for this, and can cause udelay()
           to return immediately, without any wait.  Using such a slow timer
           is silly.
      
         - VDSO support for 32-bit ARM, mainly for gettimeofday() using the
           ARM architected timer.
      
         - Perf support for Scorpion performance monitoring units"

       "The major change in this merge is the removal of the support for
        31-bit kernels.  Naturally 31-bit user space will continue to work via
        the compat layer.
      
        And then some cleanup, some improvements and bug fixes"

      i40e: get rid of unused locals · 0f575bf3
      Jesse Brandeburg authored
      These changes just remove unused variables and any code that uses them
      as the results of storing into these variables doesn't have any
      side effects that I can see or provide any benefit.

      i40e: handle possible memory allocation failure · c1147280
      Jesse Brandeburg authored
      The init_interrupt_scheme function had a possible failure
      path to allocate memory that was found by smatch.
      
      This adds the correct handling to the function to abort
      probe if the memory allocation fails.

      Linus Torvalds authored
      Pull power management and ACPI updates from Rafael Wysocki:
       "These are mostly fixes and cleanups all over, although there are a few
        items that sort of fall into the new feature category.
      
        First off, we have new callbacks for PM domains that should help us to
        handle some issues related to device initialization in a better way.
      
        There also is some consolidation in the unified device properties API
        area allowing us to use that inferface for accessing data coming from
        platform initialization code in addition to firmware-provided data.
      
        We have some new device/CPU IDs in a few drivers, support for new
        chips and a new cpufreq driver too.
      
        Specifics:
      
         - Generic PM domains support update including new PM domain callbacks
           to handle device initialization better (Russell King, Rafael J
           Wysocki, Kevin Hilman)
      
         - Unified device properties API update including a new mechanism for
           accessing data provided by platform initialization code (Rafael J
           Wysocki, Adrian Hunter)
      
         - ARM cpuidle update including ARM32/ARM64 handling consolidation
           (Daniel Lezcano)
      
         - intel_idle update including support for the Silvermont Core in the
           Baytrail SOC and for the Airmont Core in the Cherrytrail and
           Braswell SOCs (Len Brown, Mathias Krause)
      
         - New cpufreq driver for Hisilicon ACPU (Leo Yan)
      
         - intel_pstate update including support for the Knights Landing chip
           (Dasaratharaman Chandramouli, Kristen Carlson Accardi)
      
         - QorIQ cpufreq driver update (Tang Yuantian, Arnd Bergmann)
      
         - powernv cpufreq driver update (Shilpasri G Bhat)
      
         - devfreq update including Tegra support changes (Tomeu Vizoso,
           MyungJoo Ham, Chanwoo Choi)
      
         - powercap RAPL (Running-Average Power Limit) driver update including
           support for Intel Broadwell server chips (Jacob Pan, Mathias Krause)
      
         - ACPI device enumeration update related to the handling of the
           special PRP0001 device ID allowing DT-style 'compatible' property
           to be used for ACPI device identification (Rafael J Wysocki)
      
         - ACPI EC driver update including limited _DEP support (Lan Tianyu,
           Lv Zheng)
      
         - ACPI backlight driver update including a new mechanism to allow
           native backlight handling to be forced on non-Windows 8 systems and
           a new quirk for Lenovo Ideapad Z570 (Aaron Lu, Hans de Goede)
      
         - New Windows Vista compatibility quirk for Sony VGN-SR19XN (Chen Yu)
      
         - Assorted ACPI fixes and cleanups (Aaron Lu, Martin Kepplinger,
           Masanari Iida, Mika Westerberg, Nan Li, Rafael J Wysocki)
      
         - Fixes related to suspend-to-idle for the iTCO watchdog driver and
           the ACPI core system suspend/resume code (Rafael J Wysocki, Chen Yu)
      
         - PM tracing support for the suspend phase of system suspend/resume
           transitions (Zhonghui Fu)
      
         - Configurable delay for the system suspend/resume testing facility
           (Brian Norris)
      
         - PNP subsystem cleanups (Peter Huewe, Rafael J Wysocki)"
