      Pull ARM SoC platform updates from Arnd Bergmann:
       "A couple of platforms change hands in the MAINTAINERS file:
      
         - Linus Walleij lists himself for the ARM Reference platforms:
           versatile, vexpress, integrator and realview. He has been the main
           contributor for these for a while, and makes it official now.
      
         - Vladimir Zapolskiy takes over the LPC18xx platform from Joachim
           Eastwood
      
         - Manivannan Sadhasivam becomes a secondary maintainer for the
           Actions Semi machines
      
         - Nicolas Ferre lists updates the MAINTAINER listing for the AT91
           platform: Ludovic Desroches is now a co-maintainer for the
           platform, and several other people (Claudiu Beznea, Cristian
           Birsan, Eugen Hristev, Codrin Ciubotariu) take over individual
           device drivers.
      
        Thanks everyone for working on this, and welcome to the new
        maintainers!
      
        The "virt" platform on qemy or kvm can now be used in big-endian mode
        without additional tricks, thanks to Jason Donenfeld.
      
        Once again, we gain support for another NXP i.MX6 variant, this time
        it's the i.MX 6ULZ 32-bit single-core version.
      
        On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
        and RZ/G2M (r8a774a1). These are described as microcontrollers on the
        manufacturer website, but appear to be rather powerful. The RZ/G2M is
        used on the reference board for the CIP Super Long Term Support (SLTS)
        Linux Kernels"

      Linus Torvalds authored
      Pull ARM SoC driver updates from Arnd Bergmann:
       "The most noteworthy SoC driver changes this time include:
      
         - The TEE subsystem gains an in-kernel interface to access the TEE
           from device drivers.
      
         - The reset controller subsystem gains a driver for the Qualcomm
           Snapdragon 845 Power Domain Controller.
      
         - The Xilinx Zynq platform now has a firmware interface for its
           platform management unit. This contains a firmware "ioctl"
           interface that was a little controversial at first, but the version
           we merged solved that by not exposing arbitrary firmware calls to
           user space.
      
         - The Amlogic Meson platform gains a "canvas" driver that is used for
           video processing and shared between different high-level drivers.
      
        The rest is more of the usual, mostly related to SoC specific power
        management support and core drivers in drivers/soc:
      
         - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
           features related to power and reset control.
      
         - The Mediatek mt8183 and mt6765 SoC platforms gain support for their
           respective power management chips.
      
         - A new driver for NXP i.MX8, which need a firmware interface for
           power management.
      
         - The SCPI firmware interface now contains support estimating power
           usage of performance states
      
         - The NVIDIA Tegra "pmc" driver gains a few new features, in
           particular a pinctrl interface for configuring the pads.
      
         - Lots of small changes for Qualcomm, in particular the "smem" device
           driver.
      
         - Some cleanups for the TI OMAP series related to their sysc
           controller.
      
        Additional cleanups and bugfixes in SoC specific drivers include the
        Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"

      Pull ARM SoC device tree updates from Arnd Bergmann:
       "There are close to 800 indivudal changesets in this branch again,
        which feels like a lot. There are particularly many changes for the
        NVIDIA Tegra platform this time, in fact more than it has seen in the
        two years since the v4.9 merge window. Aside from this, it's been
        fairly normal, with lots of changes going into Renesas R-CAR, NXP
        i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP.
      
        Most of the changes are for adding new features into existing boards,
        for brevity I'm only mentioning completely new machines and SoCs here.
        For the first time I think we have (slightly) more new 64-bit hardware
        than 32-bit:
      
        Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
        computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a
        minor variation of the motherboards of the GTA04 phone, see
        https://shop.goldelico.com/wiki.php?page=GTA04A5
      
        Clearfog is a nice little board for quad-core Marvell Armada 8040
        network processor, see
        https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
      
        Two additional server boards come with the Aspeed baseboard management
        controllers: Stardragon4800 is an arm64 reference platform made by HXT
        (based on Qualcomm's server chips), and TiogaPass is an Open Compute
        mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the
        BMC.
      
        NXP i.MX usually sees a lot of new boards each release. This time
        there we only add one minor variant: ConnectCore 6UL SBC Pro uses the
        same SoM design as the ConnectCore 6UL SBC Express added later.
        However, there is a new chip, the i.MX6ULZ, which is an even smaller
        variant of the i.MX6ULL, with features removed. There is also support
        for the reference board design, the i.MX6ULZ 14x14 EVK.
      
        A new Raspberry Pi variant gets added, this one is the CM3 compute
        module based on bcm2837, it was launched in early 2017 but only now
        added to the kernel, both as 32-bit and as 64-bit files, as we tend to
        do for Raspberry Pi.
      
        On the Allwinner side, everything is again about cheap development
        boards, usually of the "Fruit Pi" variety. The new ones this time are:
         - Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
         - Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
         - Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
         - Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
        The last one of these is now a 64-bit version of the earlier Banana Pi
        M2+ H3, with the same board layout.
      
        Similarly, for Rockchips, get get another variant of the 32-bit Asus
        Tinker board, the model 'S' based on rk3288, and three now boards
        based on the popular RK3399 chip:
         - ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
         - Rock960: https://www.96boards.org/product/rock960/
         - RockPro64: https://www.pine64.org/?page_id=61454
        These are all quite powerful boards with lots of RAM and I/O, and the
        RK3399 is the same chip used in several Chromebooks. Finally, we get
        support for the PX30 (aka rk3326) chip, which is based on the low-end
        64-bit Cortex-A35 CPU core. So far, only the evaluation board is
        supported.
      
        One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is
        based on the MT7622 WiFi router platform, and the first product I've
        seen with a 64-bit Mediatek chip in that market:
        http://www.banana-pi.org/r64.html
      
        For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
        development board, which are similar to the Hi3660 and Hikey 360
        respectively, but add support for an NPU.
      
        Amlogic gets initial support for the Meson-G12A chip (S905D2), another
        quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit
        side, we gain support for an actual end-user product, the Endless
        Computers Endless Mini based on Meson8b (S805), see
        https://endlessos.com/computers/
      
        Qualcomm adds support for their MSM8998 SoC and evaluation platform.
        This chip is commonly known as the Snapdragon 835, and is used in
        high-end phones as well as low-end laptops.
      
        For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
        but no boards for this one. However, we do add boards for the
        previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the
        M3NULCB Starter Kit Pro.
      
        While we have lots of DT changes for NVIDIA to update the existing
        files, the only board that gets added is the Toradex Colibri T20 on
        Colibri Evaluation Board for the old Tegra2.
      
        Synaptics add support for their AS370 SoC, which is part of the
        (formerly Marvell) Berlin line of set-top-box chips used e.g. in the
        various Google Chromecast. Only the .dtsi gets added at this point, no
        actual machines"

      i2c: uniphier-f: fix race condition when IRQ is cleared · eaba6878
      Masahiro Yamada authored
      The current IRQ handler clears all the IRQ status bits when it bails
      out. This is dangerous because it might clear away the status bits
      that have just been set while processing the current handler. If this
      happens, the IRQ event for the latest transfer is lost forever.
      
      The IRQ status bits must be cleared *before* the next transfer is
      kicked.

      i2c: uniphier-f: fix occasional timeout error · 39226aaa
      Masahiro Yamada authored
      Currently, a timeout error could happen at a repeated START condition.
      
      For a (non-repeated) START condition, the controller starts sending
      data when the UNIPHIER_FI2C_CR_STA bit is set. However, for a repeated
      START condition, the hardware starts running when the slave address is
      written to the TX FIFO - the write to the UNIPHIER_FI2C_CR register is
      actually unneeded.
      
      Because the hardware is already running before the IRQ is enabled for
      a repeated START, the driver may miss the IRQ event. In most cases,
      this problem does not show up since modern CPUs are much faster than
      the I2C transfer. However, it is still possible that a context switch
      happens after the controller starts, but before the IRQ register is
      set up.
      
      To fix this,
      
       - Do not write UNIPHIER_FI2C_CR for repeated START conditions.
      
       - Enable IRQ *before* writing the slave address to the TX FIFO.
      
       - Disable IRQ for the current CPU while queuing up the TX FIFO;
         If the CPU is interrupted by some task, the interrupt handler
         might be invoked due to the empty TX FIFO before completing the
         setup.

      i2c: uniphier-f: make driver robust against concurrency · f1fdcbbd
      Masahiro Yamada authored
      This is unlikely to happen, but it is possible for a CPU to enter
      the interrupt handler just after wait_for_completion_timeout() has
      expired. If this happens, the hardware is accessed from multiple
      contexts concurrently.
      
      Disable the IRQ after wait_for_completion_timeout(), and do nothing
      from the handler when the IRQ is disabled.

      HID: input: simplify/fix high-res scroll event handling · 044ee890
      Linus Torvalds authored
      Commit 1ff2e1a4 ("HID: input: Create a utility class for counting
      scroll events") created the helper function
      
          hid_scroll_counter_handle_scroll()
      
      to handle high-res scroll events and also expose them as regular wheel
      events.
      
      But the resulting algorithm was unstable, and causes scrolling to be
      very unreliable.  When you hit the half-way mark of the highres
      multiplier, small highres movements will incorrectly translate into big
      traditional wheel movements, causing odd jitters.
      
      Simplify the code and make the output stable.
      
      NOTE! I'm pretty sure this will need further tweaking.  But this at
      least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into
      a usable one.

        spotting any files that don't use the asm-generic ABI itself, and
        having it changed to it matches exactly what we do on other new
        architectures.
      
        I also looked at every other patch and commented on maybe half of them
        where I saw something that did not quite seem right. Others have
        reviewed specific patches in greater depth. I'm sure that one could
        fine more of the minor details, but as long as they are not ABI
        relevant, they can be fixed later.
      
        The only patch that is part of the ABI and that nobody reviewed is the
        signal handling. This is one of the areas I never worked on in much
        detail. I did not see anything wrong with it, but I also don't know
        what the problems with the other architectures are here, and we seem
        to be hitting issues occasionally, and we never managed to generalize
        this enough for new architectures to have a trivial implementation.
      
        I was originally hoping that we could have the 64-bit time_t
        interfaces ready in time to completely drop the 32-bit ones, but that
        did not happen. We might still remove them in the next merge window
        depending on whether the libc upstream people prefer to keep them or
        not.
      
        One more general comment: I think this may well be the last new CPU
        architecture we ever add to the kernel. Both nds32 and c-sky are made
        by companies that also work on risc-v, and generally speaking risc-v
        seems to be killing off any of the minor licensable instruction set
        projects, just like ARM has mostly killed off the custom
        vendor-specific instruction sets already.
      
        If we add another architecture in the future, it may instead be
        something like the LLVM bitcode or WebAssembly, who knows?"
      
      To which Geert Uytterhoeven pipes in about another architecture still in
      the pipeline: Kalray MPPA.

      net: diag: document swapped src/dst in udp_dump_one. · 747569b0
      Lorenzo Colitti authored
      Since its inception, udp_dump_one has had a bug where userspace
      needs to swap src and dst addresses and ports in order to find
      the socket it wants. This is because it passes the socket source
      address to __udp[46]_lib_lookup's saddr argument, but those
      functions are intended to find local sockets matching received
      packets, so saddr is the remote address, not the local address.
      
      This can no longer be fixed for backwards compatibility reasons,
      so add a brief comment explaining that this is the case. This
      will avoid confusion and help ensure SOCK_DIAG implementations
      of new protocols don't have the same problem.

      macsec: linkstate fixes
      
      This series fixes issues with handling administrative and operstate of
      macsec devices.
      
      Radu Rendec proposed another version of the first patch [0] but I'd
      rather not follow the behavior of vlan devices, going with macvlan
      does instead. Patrick Talbert also reported the same issue to me.
      
      The second patch is a follow-up. The restriction on setting the device
      up is a bit unreasonable, and operstate provides the information we
      need in this case.

      macsec: let the administrator set UP state even if lowerdev is down · 07bddef9
      Sabrina Dubroca authored
      Currently, the kernel doesn't let the administrator set a macsec device
      up unless its lower device is currently up. This is inconsistent, as a
      macsec device that is up won't automatically go down when its lower
      device goes down.
      
      Now that linkstate propagation works, there's really no reason for this
      limitation, so let's remove it.

      macsec: update operstate when lower device changes · e6ac0758
      Sabrina Dubroca authored
      Like all other virtual devices (macvlan, vlan), the operstate of a
      macsec device should match the state of its lower device. This is done
      by calling netif_stacked_transfer_operstate from its netdevice notifier.
      
      We also need to call netif_stacked_transfer_operstate when a new macsec
      device is created, so that its operstate is set properly. This is only
      relevant when we try to bring the device up directly when we create it.
      
      Radu Rendec proposed a similar patch, inspired from the 802.1q driver,
      that included changing the administrative state of the macsec device,
      instead of just the operstate. This version is similar to what the
      macvlan driver does, and updates only the operstate.

      net: sched: gred: pass the right attribute to gred_change_table_def() · 38b4f18d
      Jakub Kicinski authored
      gred_change_table_def() takes a pointer to TCA_GRED_DPS attribute,
      and expects it will be able to interpret its contents as
      struct tc_gred_sopt.  Pass the correct gred attribute, instead of
      TCA_OPTIONS.
      
      This bug meant the table definition could never be changed after
      Qdisc was initialized (unless whatever TCA_OPTIONS contained both
      passed netlink validation and was a valid struct tc_gred_sopt...).
      
      Old behaviour:
      $ ip link add type dummy
      $ tc qdisc replace dev dummy0 parent root handle 7: \
           gred setup vqs 4 default 0
      $ tc qdisc replace dev dummy0 parent root handle 7: \
           gred setup vqs 4 default 0
      RTNETLINK answers: Invalid argument
      
      Now:
      $ ip link add type dummy
      $ tc qdisc replace dev dummy0 parent root handle 7: \
           gred setup vqs 4 default 0

      kthread_create_worker takes fmt+varargs to set the name of the
      worker, and that happens with a vsnprintf() to a stack buffer (that is
      then copied into task_comm). So there's no reason not to just pass

      net: bridge: remove ipv6 zero address check in mcast queries · 0fe5119e
      Nikolay Aleksandrov authored
      Recently a check was added which prevents marking of routers with zero
      source address, but for IPv6 that cannot happen as the relevant RFCs
      actually forbid such packets:
      RFC 2710 (MLDv1):
      "To be valid, the Query message MUST
       come from a link-local IPv6 Source Address, be at least 24 octets
       long, and have a correct MLD checksum."
      
      Same goes for RFC 3810.
      
      And also it can be seen as a requirement in ipv6_mc_check_mld_query()
      which is used by the bridge to validate the message before processing
      it. Thus any queries with :: source address won't be processed anyway.
      So just remove the check for zero IPv6 source address from the query
      processing function.
      
      Fixes: 5a2de63f ("bridge: do not add port to router list when receives query with source 0.0.0.0")

      Merge branch 'xarray' of git://git.infradead.org/users/willy/linux-dax · dad4f140
      Linus Torvalds authored
      Pull XArray conversion from Matthew Wilcox:
       "The XArray provides an improved interface to the radix tree data
        structure, providing locking as part of the API, specifying GFP flags
        at allocation time, eliminating preloading, less re-walking the tree,
        more efficient iterations and not exposing RCU-protected pointers to
        its users.
      
        This patch set
      
         1. Introduces the XArray implementation
      
         2. Converts the pagecache to use it
      
         3. Converts memremap to use it
      
        The page cache is the most complex and important user of the radix
        tree, so converting it was most important. Converting the memremap
        code removes the only other user of the multiorder code, which allows
        us to remove the radix tree code that supported it.
      
        I have 40+ followup patches to convert many other users of the radix
        tree over to the XArray, but I'd like to get this part in first. The
        other conversions haven't been in linux-next and aren't suitable for
        applying yet, but you can see them in the xarray-conv branch if you're
        interested"

      Just like with normal GRO processing, we have to initialize
      skb->next to NULL when we unlink overflow packets from the
      GRO hash lists.
      
      Fixes: d4546c25 ("net: Convert GRO SKB handling to list_head.")

      modpost: Create macro to avoid variable shadowing · c2b1a922
      Leonardo Bras authored
      Create DEF_FIELD_ADDR_VAR as a more generic version of the DEF_FIELD_ADD
      macro, allowing usage of a variable name other than the struct element name.
      Also, sets DEF_FIELD_ADDR as a specific usage of DEF_FILD_ADDR_VAR in which
      the var name is the same as the struct element name.
      Then, makes use of DEF_FIELD_ADDR_VAR to create a variable of another name,
      in order to avoid variable shadowing.

      parisc: Fix A500 boot crash · c9fa406f
      John David Anglin authored
      I believe the following change will fix the cache/TLB inconsistency
      observed by Meelis.  After changing the page table entries, we need to
      flush the cache and TLB to ensure that we don't have any stale PTE
      values in the cache or TLB.
      
      The alternative patching is done after all CPUs are running.  Thus, we
      need to flush the whole cache and TLB.
      
      I included the init section in the range modified by map_pages as
      suggested by Helge.  Some routines in the init section may require
      patching.
