      Pull slab updates from Vlastimil Babka:
      
       - SLAB deprecation:
      
         Following the discussion at LSF/MM 2023 [1] and no objections, the
         SLAB allocator is deprecated by renaming the config option (to make
         its users notice) to CONFIG_SLAB_DEPRECATED with updated help text.
         SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are
         also updated.
      
       - SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer):
      
         There are (very limited) cases where kmem_cache merging is
         undesirable, and existing ways to prevent it are hacky. Introduce a
         new flag to do that cleanly and convert the existing hacky users.
         Btrfs plans to use this for debug kernel builds (that use case is
         always fine), networking for performance reasons (that should be very
         rare).
      
       - Replace the usage of weak PRNGs (David Keisar Schmidt):
      
         In addition to using stronger RNGs for the security related features,
         the code is a bit cleaner.
      
       - Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and
         zhaoxinchao)

      Pull new ARM SoC support from Arnd Bergmann:
       "There are two new SoC families this time, and both appear fairly
        similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are
        both dual-core Cortex-A35 based chips for the low-power industrial
        embedded market, and they mark the first 64-bit product in a widely
        used family of 32-bit Arm MCUs and SoCs.
      
        The way into the kernel is completely different here: The team at ST
        has a long history of working upstream with their STM32MP1 and other
        SoCs, and they produced a complete port to arm64 together with the
        initial announcement. Nuvoton also has multiple SoC product lines with
        current or previous upstream support, but those are maintained by
        third parties and are unrelated. The patch series from Nuvoton's Jacky
        Huang had to go through many revisisions to get to this point and is
        still missing a few drivers including the serial port for the moment.
      
        The branch contains the devicetree files as well as all the code
        changes, in order to have something that can be tested standalone"

      Pull ARM SoC devicetree updates from Arnd Bergmann:
       "The biggest change this time is for the 32-bit devicetree files, which
        are all moved to a new location, using separate subdirectories for
        each SoC vendor, following the same scheme that is used on arm64, mips
        and riscv. This has been discussed for many years, but so far we never
        did this as there was a plan to move the files out of the kernel
        entirely, which has never happened.
      
        The impact of this will be that all external patches no longer apply,
        and anything depending on the location of the dtb files in the build
        directory will have to change. The installed files after 'make
        dtbs_install' keep the current location.
      
        There are six added SoCs here that are largely variants of previously
        added chips. Two other chips are added in a separate branch along with
        their device drivers.
      
         - The Samsung Exynos 4212 makes its return after the Samsung Galaxy
           Express phone is addded at last. The SoC support was originally
           added in 2012 but removed again in 2017 as it was unused at the
           time.
      
         - Amlogic C3 is a Cortex-A35 based smart IP camera chip
      
         - Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
           the still common MSM8916 (Snapdragon 410) phone chip that has been
           supported for a long time.
      
         - Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
           laptop chips, used in the Lenovo Flex 5G, which is added along with
           the reference board.
      
         - Qualcomm SDX75 is the latest generation modem chip that is used as
           a peripherial in phones but can also run a standalone Linux. Unlike
           the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.
      
         - Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the
           Xuantie C910 core, a step up from all previously added rv64 chips.
      
        All of the above come with reference board implementations, those
        included there are 39 new board files, but only five more 32-bit this
        time, probably a new low:
      
         - Marantec Maveo board based on dhcor imx6ull module
      
         - Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip
      
         - Epson Moverio BT-200 AR glasses based on TI OMAP4
      
         - PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM
      
         - ICnova ADB4006 board based on Allwinner A20
      
        On the 64-bit side, there are also fewer addded machines than we had
        in the recent releases:
      
         - Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM
           EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device.
      
         - NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234
      
         - Qualcomm gains support for 6 reference boards on various members of
           their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua
           phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top
           of the various reference platforms for their new chips.
      
         - Rockchips support for several newer boards: Indiedroid Nova
           (rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM
           NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn
           Fastrhino R66S/R68S (rk3568)
      
         - TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex
           Verdin family with AM62 COM, carrier and dev boards
      
        Other changes to existing boards contain the usual minor improvements
        along with
      
         - continued updates to clean up dts files based on dtc warnings and
           binding checks, in particular cache properties and node names
      
         - support for devicetree overlays on at91, bcm283x
      
         - significant additions to existing SoC support on mediatek,
           qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST
           STM32MP1
