git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 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.

2018-10-29i2c: uniphier-f: fix race condition when IRQ is clearedMasahiro Yamada
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.

2018-10-29i2c: uniphier-f: fix occasional timeout errorMasahiro Yamada
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.

2018-10-29i2c: uniphier-f: make driver robust against concurrencyMasahiro Yamada
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.

2018-10-29HID: input: simplify/fix high-res scroll event handlingLinus Torvalds
Commit 1ff2e1a44e02 ("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.

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?"

2018-10-28net: diag: document swapped src/dst in udp_dump_one.Lorenzo Colitti
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.

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.

2018-10-28macsec: let the administrator set UP state even if lowerdev is downSabrina Dubroca
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.

2018-10-28macsec: update operstate when lower device changesSabrina Dubroca
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.

2018-10-28net: bridge: remove ipv6 zero address check in mcast queriesNikolay Aleksandrov
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.

2018-10-28Merge branch 'xarray' of git://git.infradead.org/users/willy/linux-daxLinus Torvalds
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" * 'xarray' of git://git.infradead.org/users/willy/linux-dax: (90 commits) radix tree: Remove multiorder support radix tree test: Convert multiorder tests to XArray radix tree tests: Convert item_delete_rcu to XArray radix tree tests: Convert item_kill_tree to XArray radix tree tests: Move item_insert_order radix tree test suite: Remove multiorder benchmarking radix tree test suite: Remove __item_insert memremap: Convert to XArray xarray: Add range store functionality xarray: Move multiorder_check to in-kernel tests xarray: Move multiorder_shrink to kernel tests xarray: Move multiorder account test in-kernel radix tree test suite: Convert iteration test to XArray radix tree test suite: Convert tag_tagged_items to XArray radix tree: Remove radix_tree_clear_tags radix tree: Remove radix_tree_maybe_preload_order radix tree: Remove split/join code radix tree: Remove radix_tree_update_node_t page cache: Finish XArray conversion dax: Convert page fault handlers to XArray ...
2018-10-28net: Properly unlink GRO packets on overflow.David S. Miller
Just like with normal GRO processing, we have to initialize skb->next to NULL when we unlink overflow packets from the GRO hash lists.

2018-10-29modpost: Create macro to avoid variable shadowingLeonardo Bras
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.

2018-10-28parisc: Fix A500 boot crashJohn David Anglin
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. Signed-off-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de>
2018-10-27HID: we do not randomly make new drivers 'default y'Linus Torvalds
.. even when that "default y" is hidden syntactically as a default !EXPERT it's wrong. The only reason something should be 'default y' is if it used to be built-in, and it was made configurable, and the 'default y' is just retaining the status quo. Altheratively, the hardware for the driver has become _so_ common that it really makes sense for everybody to build it. Finally, one possible reason for 'default y' is because the option is not enabling any new code at all, but is just enabling other options (the networking people do this for vendor options, for example, so that you can disable whole vendors at a time). Clearly, none of these cases hold for the BigBen Interactive Kids' gamepad, and HID_BIGBEN_FF should thus most definitely not default to on for everybody.
