      Pull HID subsystem updates from Jiri Kosina:
      
       - The need for HID_QUIRK_NO_INIT_REPORTS per-device quirk has been
         growing dramatically during past years, so the time has come to
         switch over the default, and perform the pro-active reading only in
         cases where it's really needed (multitouch, wacom).
      
         The only place where this behavior is (in some form) preserved is
         hiddev so that we don't introduce userspace-visible change of
         behavior.
      
         From Benjamin Tissoires
      
       - HID++ support for power_supply / baterry reporting.
      
         From Benjamin Tissoires and Bastien Nocera
      
       - Vast improvements / rework of DS3 and DS4 in Sony driver.
      
         From Roderick Colenbrander
      
       - Improvment (in terms of getting closer to the Microsoft's
         interpretation of slightly ambiguous specification) of logical range
         interpretation in case null-state is set in the rdesc.
      
         From Valtteri Heikkilä and Tomasz Kramkowski
      
       - A lot of newly supported device IDs and small assorted fixes

      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for the v4.12 cycle.
      
        The extra week before the merge window actually resulted in some of
        the type of fixes that usually arrive after the merge window already
        starting to trickle in from eager developers using -next, I'm
        impressed.
      
        I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal
        with the onset of Samsung patches. It works great.
      
        Apart from that it is a boring round, just incremental updates and
        fixes all over the place, no serious core changes or anything exciting
        like that. The most pleasing to see is Julia Cartwrights work to audit
        the irqchip-providing drivers for realtime locking compliance. It's
        one of those "I should really get around to looking into that" things
        that have been on my TODO list since forever.
      
        Summary:
      
        Core changes:
      
         - add bi-directional and output-enable pin configurations to the
           generic bindings and generic pin controlling core.
      
        New drivers or subdrivers:
      
         - Armada 37xx SoC pin controller and GPIO support.
      
         - Axis ARTPEC-6 SoC pin controller support.
      
         - AllWinner A64 R_PIO controller support, and opening up the
           AllWinner sunxi driver for ARM64 use.
      
         - Rockchip RK3328 support.
      
         - Renesas R-Car H3 ES2.0 support.
      
         - STM32F469 support in the STM32 driver.
      
         - Aspeed G4 and G5 pin controller support.
      
        Improvements:
      
         - a whole slew of realtime improvements to drivers implementing
           irqchips: BCM, AMD, SiRF, sunxi, rockchip.
      
         - switch meson driver to get the GPIO ranges from the device tree.
      
         - input schmitt trigger support on the Rockchip driver.
      
         - enable the sunxi (AllWinner) driver to also be used on ARM64
           silicon.
      
         - name the Qualcomm QDF2xxx GPIO lines.
      
         - support GMMR GPIO regions on the Intel Cherryview. This fixes a
           serialization problem on these platforms.
      
         - pad retention support for the Samsung Exynos 5433.
      
         - handle suspend-to-ram in the AT91-pio4 driver.
      
         - pin configuration support in the Aspeed driver.
      
        Cleanups:
      
         - the final name of Rockchip RK1108 was RV1108 so rename the driver
           and variables to stay consistent"

      net: thunderx: Optimize page recycling for XDP · 77322538
      Sunil Goutham authored
      Driver follows a method of taking one extra reference on the
      page for recycling which is fine in usual packet path where
      each 64KB page is segmented into multiple receive buffers.
      
      But in XDP mode since there is just one receive buffer per
      page taking extra page reference itself becomes big bottleneck
      consuming ~50% of CPU cycles due to atomic operations.
      
      This patch adds a internal ref count in pgcache for each
      page and additional page references are taken in a batch
      instead of just one at a time. Internal i.e 'pgcache->ref_count'
      and page's i.e 'page->_refcount' counters are compared to check
      page's recyclability.

      is not necessary and will become a bottleneck. Hence added
      a separate 'xdp_free_cnt' used for SQs designated for XDP
      to track descriptor free count.
      
      Changes also include
      - A new entry 'xdp_page' is added to save transmitted packet's
        page pointer for later cleanup.
      - XDP Tx SQ's doorbell is ringed once per NAPI instance.
      - Retrieving designated SQ for packets being sent out by stack
        via 'nicvf_xmit'.

      Sunil Goutham authored
      Adds basic XDP support i.e attaching a BPF program to an
      interface. Also takes care of allocating separate Tx queues
      for XDP path and for network stack packet transmission.
      
      This patch doesn't support handling of any of the XDP actions,
      all are treated as XDP_PASS i.e packets will be handed over to
      the network stack.
      
      Changes also involve allocating one receive buffer per page in XDP
      mode and multiple in normal mode i.e when no BPF program is attached.

      Sunil Goutham authored
      Adds support for page recycling for allocating receive buffers
      to reduce cost of refilling RBDR ring. Also got rid of using
      compound pages when pagesize is 4K, only order-0 pages now.
      
      Only page is recycled, DMA mappings still needs to be done for
      every receive buffer allocated due to following constraints
      - Cannot have just one receive buffer per 64KB page.
      - There is just one buffer ring shared across 8 Rx queues, so
        buffers of same page can go to any Rx queue.
      - HW gives buffer address where packet has been DMA'ed and not
        the index into buffer ring.
      This makes it not possible to resue DMA mapping info. So unfortunately
      have to go through costly mapping route for every buffer.

      PTP hardware filter configuration performed by the driver for a given
      user requested config is not correct for some of the PTP modes.
      Following changes are needed for PTP config-filter implementation.
       1. NIG_REG_TX_PTP_EN register - Bits 0/1/2 respectively enables
          TimeSync/"V1 frame format support"/"V2 frame format support" on
          the TX side. Set the associated bits based on the user request.
       2. ptp4l application fails to operate in Peer Delay mode. Following
          changes are needed to fix this,
          a. Driver should enable (set to 0) DA #1-related bits for IPv4,
             IPv6 and MAC destination addresses in these registers:
               NIG_REG_TX_LLH_PTP_RULE_MASK

          b. NIG_REG_LLH_PTP_PARAM_MASK/NIG_REG_TX_LLH_PTP_PARAM_MASK should

      bpf, arm64: fix jit branch offset related to ldimm64 · ddc665a4
      Daniel Borkmann authored
      When the instruction right before the branch destination is
      a 64 bit load immediate, we currently calculate the wrong
      jump offset in the ctx->offset[] array as we only account
      one instruction slot for the 64 bit load immediate although
      it uses two BPF instructions. Fix it up by setting the offset
      into the right slot after we incremented the index.

      bpf, arm64: implement jiting of BPF_XADD · 85f68fe8
      Daniel Borkmann authored
      This work adds BPF_XADD for BPF_W/BPF_DW to the arm64 JIT and therefore
      completes JITing of all BPF instructions, meaning we can thus also remove
      the 'notyet' label and do not need to fall back to the interpreter when
      BPF_XADD is used in a program!
      
      This now also brings arm64 JIT in line with x86_64, s390x, ppc64, sparc64,

      I say:
      
      ====================
      Fix some bpf program testing framework bugs
      
      This series fixes two issue:
      
      1) Accidental user pointer dereference in bpf_test_finish()
      
      2) The packet data given to the test programs is not aligned correctly
      
      The first issue is fixed simply because we have a kernel side copy
      of the datastructure in question already.  And the second bug is
      a simple matter of applying NET_IP_ALIGN where needed.

      Make sure we apply NET_IP_ALIGN when reserving headroom for SKB
      and XDP test runs, just like a real driver would.
