      Linus Torvalds authored
      Pull arm64 updates from Catalin Marinas:
      
       - KCSAN enabled for arm64.
      
       - Additional kselftests to exercise the syscall ABI w.r.t. SVE/FPSIMD.
      
       - Some more SVE clean-ups and refactoring in preparation for SME
         support (scalable matrix extensions).
      
       - BTI clean-ups (SYM_FUNC macros etc.)
      
       - arm64 atomics clean-up and codegen improvements.
      
       - HWCAPs for FEAT_AFP (alternate floating point behaviour) and
         FEAT_RPRESS (increased precision of reciprocal estimate and
         reciprocal square root estimate).
      
       - Use SHA3 instructions to speed-up XOR.
      
       - arm64 unwind code refactoring/unification.
      
       - Avoid DC (data cache maintenance) instructions when DCZID_EL0.DZP ==
         1 (potentially set by a hypervisor; user-space already does this).
      
       - Perf updates for arm64: support for CI-700, HiSilicon PCIe PMU,
         Marvell CN10K LLC-TAD PMU, miscellaneous clean-ups.
      
       - Other fixes and clean-ups; highlights: fix the handling of erratum
         1418040, correct the calculation of the nomap region boundaries,
         introduce io_stop_wc() mapped to the new DGH instruction (data
         gathering hint).

      Pull RISC-V SoC updates from Arnd Bergmann:
       "Add support for StarFive JH7100 RISC-V SoC
      
        This adds support for the StarFive JH7100, including the necessary
        device drivers and DT files for the BeagleV Starlight prototype board,
        with additional boards to be added later. This SoC promises to be the
        first usable low-cost platform for RISC-V.
      
        I've taken this through the SoC tree in the anticipation of adding a
        few other Arm based SoCs as well, but those did not pass the review in
        time, so it's only this one"

      Pull ARM SoC devicetree updates from Arnd Bergmann:
       "As usual, this is the bulk of the updates for the SoC tree, adding
        more devices to existing files, addressing issues from ever improving
        automated checking, and fixing minor issues.
      
        The most interesting bits as usual are the new platforms. All the
        newly supported SoCs belong into existing families this time:
      
         - Qualcomm gets support for two newly announced platforms, both of
           which can now work in production environments: the SDX65 5G modem
           that can run a minimal Linux on its Cortex-A7 core, and the
           Snapdragon 8 Gen 1, their latest high-end phone SoC.
      
         - Renesas adds support for R-Car S4-8, the most recent automotive
           Server/Communication SoC.
      
         - TI adds support for J721s2, a new automotive SoC in the K3 family.
      
         - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
           generation following their popular MT76xx series. Only basic
           support is added for now.
      
         - NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8
           series.
      
         - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we
           have supported for a long time.
      
        New boards with the existing SoCs include
      
         - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
      
         - AT91/SAMA5 based evaluation board
      
         - NXP gains twenty new development and industrial boards for their
           i.MX and Layerscape SoCs
      
         - Intel IXP4xx now supports the final two machines in device tree
           that were previously only supported in old style board files.
      
         - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while
           MT8183 is used in the Acer Chromebook 314.
      
         - Qualcomm gains support for the reference machines using the two new
           SoCs, plus a number of Chromebook variants and phones based on the
           Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia
           devices and the Microsoft Surface Duo 2.
      
         - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
      
         - Tegra now boots various older Android devices based on 32-bit chips
           out of the box, including a number of ASUS Transformer tablets.
      
           There is also a new Jetson AGX Orin developer kit.
      
         - Apple support adds the missing device trees for all the remaining
           M1 Macbook and iMac variants, though not yet the M1 Pro/Max
           versions.
      
         - Allwinner now supports another version of the Tanix TX6 set-top box
           based on the H6 SoC.
      
         - Broadcom gains support for the Netgear RAXE500 Wireless router
           based on BCM4908"
