      Pull powerpc updates from Michael Ellerman:
       "Highlights include:
      
         - Support for the kexec_file_load() syscall, which is a prereq for
           secure and trusted boot.
      
         - Prevent kernel execution of userspace on P9 Radix (similar to
           SMEP/PXN).
      
         - Sort the exception tables at build time, to save time at boot, and
           store them as relative offsets to save space in the kernel image &
           memory.
      
         - Allow building the kernel with thin archives, which should allow us
           to build an allyesconfig once some other fixes land.
      
         - Build fixes to allow us to correctly rebuild when changing the
           kernel endian from big to little or vice versa.
      
         - Plumbing so that we can avoid doing a full mm TLB flush on P9
           Radix.
      
         - Initial stack protector support (-fstack-protector).
      
         - Support for dumping the radix (aka. Linux) and hash page tables via
           debugfs.
      
         - Fix an oops in cxl coredump generation when cxl_get_fd() is used.
      
         - Freescale updates from Scott: "Highlights include 8xx hugepage
           support, qbman fixes/cleanup, device tree updates, and some misc
           cleanup."
      
         - Many and varied fixes and minor enhancements as always.

      Pull m ore s390 updates from Martin Schwidefsky:
       "Over 95% of the changes in this pull request are related to the zcrypt
        driver. There are five improvements for zcrypt: the ID for the CEX6
        cards is added, workload balancing and multi-domain support are
        introduced, the debug logs are overhauled and a set of tracepoints is
        added.
      
        Then there are several patches in regard to inline assemblies. One
        compile fix and several missing memory clobbers. As far as we can tell
        the omitted memory clobbers have not caused any breakage.
      
        A small change to the PCI arch code, the machine can tells us how big
        the function measurement blocks are. The PCI function measurement will
        be disabled for a device if the queried length is larger than the
        allocated size for these blocks.
      
        And two more patches to correct five printk messages.
      
        That is it for s390 in regard to the 4.10 merge window. Happy holidays"

        This includes the new virtio crypto device, and fixes all over the
        place. In particular enabling endian-ness checks for sparse builds
        found some bugs which this fixes. And it appears that everyone is in
        agreement that disabling endian-ness sparse checks shouldn't be
        necessary any longer.
      
        So this enables them for everyone, and drops the __CHECK_ENDIAN__ and
        __bitwise__ APIs.

           running on and cannot find out from DT, firmware or hardware.

           fully supported phone reference board.
         - Hisilicon Hip07 server platform and D05 board, the latest iteration
           of their product line, now with 64 Cortex-A72 cores across two
           sockets.
         - Allwinner A64 SoC, the first 64-bit chip from their "sunxi" product
           line, used in Android tablets and ultra-cheap development boards
         - NXP LS1046A Communication processor, improving on the earlier
           LS1043A with faster CPU cores
         - Qualcomm MSM8992 (Snapdragon 808) and MSM8994 (Snapdragon 810)
           mobile phone SoCs
         - Early support for the Nvidia Tegra Tegra186 SoC
         - Amlogic S905D is a minor variant of their existing Android consumer
           product line
         - Rockchip PX5 automotive platform, a close relative of their popular
           rk3368 Android tablet chips
      
        Aside from the respective evaluation platforms for the above chips,
        there are only a few consumer devices and boards added this time:
      
         - Huawei Nexus 6P (Angler) mobile phone
         - LG Nexus 5x (Bullhead) mobile phone

      Pull ARM DT updates from Arnd Bergmann:
       "Lots of changes as usual, so I'm trying to be brief here. Most of the
        new hardware support has the respective driver changes merged through
        other trees or has had it available for a while, so this is where
        things come together.
      
        We get a DT descriptions for a couple of new SoCs, all of them
        variants of other chips we already support, and usually coming with a
        new evaluation board:
      
         - Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
         - Qualcomm MDM9615 LTE baseband
         - NXP imx6ull, the latest and smallest i.MX6 application processor variant
         - Renesas RZ/G (r8a7743 and r8a7745) application processors
         - Rockchip PX3, a variant of the rk3188 chip used in Android tablets
         - Rockchip rk1108 single-core application processor
         - ST stm32f746 Cortex-M7 based microcontroller
         - TI DRA71x automotive processors
      
        These are commercially available consumer platforms we now support:
      
         - Motorola Droid 4 (xt894) mobile phone
         - Rikomagic MK808 Android TV stick based on Rockchips rx3066
         - Cloud Engines PogoPlug v3 based on OX820
         - Various Broadcom based wireless devices:
            - Netgear R8500 router
            - Tenda AC9 router
            - TP-LINK Archer C9 V1
            - Luxul XAP-1510 Access point
         - Turris Omnia open hardware router based on Armada 385
      
        And a couple of new boards targeted at developers, makers or
        industrial integration:
      
         - Macnica Sodia development platform for Altera socfpga (Cyclone V)
         - MicroZed board based on Xilinx Zynq FPGA platforms
         - TOPEET itop/elite based on exynos4412
         - WP8548 MangOH Open Hardware platform for IOT, based on Qualcomm MDM9615
         - NextThing CHIP Pro gadget
         - NanoPi M1 development board
         - AM571x-IDK industrial board based on TI AM5718
         - i.MX6SX UDOO Neo
         - Boundary Devices Nitrogen6_SOM2 (i.MX6)
         - Engicam i.CoreM6
         - Grinn i.MX6UL liteSOM/liteBoard
         - Toradex Colibri iMX6 module
      
        Other changes:
      
         - added peripherals on renesas, davinci, stm32f429, uniphier, sti,
           mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
           mvebu, allwinner, broadcom, exynos, zynq
      
         - Continued fixes for W=1 dtc warnings
      
         - The old STiH415/416 SoC support gets removed, these never made it
           into products and have served their purpose in the kernel as a
           template for teh newer chips from ST
      
         - The exynos4415 dtsi file is removed as nothing uses it.
      
         - Intel PXA25x can now be booted using devicetree"

        essentially anything that can not (yet) be expressed using DT files.
      
        Noteworthy changes include:
      
         - Added support for the TI DRA71x family of SoCs in mach-omap2, this
           is an new variant of the the DRA72x/DRA74x automotive infotainment
           chips we already supported for a while.
      
         - Added support for the ST STM32F746 SoC, the first Cortex-M7 based
           microcontroller we support, related to the smaller STM32F4 family.
      
         - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see
           http://elinux.org/RZ-G
      
         - SMP is now supported on the OX820 platform
      
         - A lot of code in mach-omap2 gets removed as a follow-up to removing
           support for board files in the previous release

      less than 10% over the 2000 sparse warnings already there.
      
      Not a big deal, OTOH enabling this helps people notice
      they are introducing new bugs.
      
      So let's just drop __CHECK_ENDIAN__. Follow-up patches
      can drop distinction between __bitwise and __bitwise__.

      vringh: kill off ACCESS_ONCE() · 9d1b972f
      Mark Rutland authored
      Despite living under drivers/ vringh.c is also used as part of the userspace
      virtio tools. Before we can kill off the ACCESS_ONCE()definition in the tools,
      we must convert vringh.c to use {READ,WRITE}_ONCE().
      
      This patch does so, along with the required include of <linux/compiler.h> for
      the relevant definitions. The userspace tools provide their own definitions in
      their own <linux/compiler.h>.

      tools/virtio: fix READ_ONCE() · 5da889c7
      Mark Rutland authored
      The virtio tools implementation of READ_ONCE() has a single parameter called
      'var', but erroneously refers to 'val' for its cast, and thus won't work unless
      there's a variable of the correct type that happens to be called 'var'.
      
      Fix this with s/var/val/, making READ_ONCE() work as expected regardless.

      crypto: add virtio-crypto driver · dbaf0624
      Gonglei authored
      This patch introduces virtio-crypto driver for Linux Kernel.
      
      The virtio crypto device is a virtual cryptography device
      as well as a kind of virtual hardware accelerator for
      virtual machines. The encryption anddecryption requests
      are placed in the data queue and are ultimately handled by
      thebackend crypto accelerators. The second queue is the
      control queue used to create or destroy sessions for
      symmetric algorithms and will control some advanced features
      in the future. The virtio crypto device provides the following
      cryptoservices: CIPHER, MAC, HASH, and AEAD.
      
      For more information about virtio-crypto device, please see:

      vhost: cache used event for better performance · 809ecb9b
      Jason Wang authored
      When event index was enabled, we need to fetch used event from
      userspace memory each time. This userspace fetch (with memory
      barrier) could be saved sometime when 1) caching used event and 2)
      if used event is ahead of new and old to new updating does not cross
      it, we're sure there's no need to notify guest.
      
      This will be useful for heavy tx load e.g guest pktgen test with Linux
      driver shows ~3.5% improvement.
