      iwlwifi: mvm: force quota update update after FW restart · e7afe89f
      Johannes Berg authored
      During firmware restart, the quota command isn't calculated multiple
      times, but after the firmware restart it has to be sent, so force it.
      Otherwise the firmware crashes.

      iwlwifi: mvm: don't power off the device between INIT and OPER firmwares · 8d193ca2
      Eran Harary authored
      Our device needs two different firmwares: the INIT firmware
      and the operational (OPER) firmware. The first one is run
      when the driver loads and it returns calibrations results
      as well as the NVM. The second one implements the WiFi
      protocol.
      
      If the wlan interface is not brought up, the device is put
      to low power state: no firmware will be running. When the
      interface is brought up, we would run the OPER firmware
      only and reuse the results of the run of the INIT firmware
      when the driver was loaded. This is changing with this
      patch.
      We now run the INIT firmware every time mac80211 calls
      start(). The penalty for that is minimal since the INIT
      firwmare run fast. I now also avoid to power down the device
      between the INIT and OPER firmware on certains buses.
      
      The motivation for this change is that there are components
      on the device (MFUART) that are triggered by the INIT
      firmware and need the device to be powered up in order to
      keep running. Powering the device down between the INIT and
      OPER firmware would stop these components and prevent them
      from running again since they are triggered by the INIT
      firmware only.
      The new flow allows this and also allows to trigger these
      components again when the interface is brought up after
      it has been brought down.

      Pull networking updates from David Miller:
      
       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.
      
      16) Convert PTP get/set methods to use 64-bit time, from Richard
          Cochran.

      Linus Torvalds authored
      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"
      
      vdso semantic conflict fixed up as per linux-next.
