      Linus Torvalds authored 
      Pull alpha updates from Arnd Bergmann:
 "I had investigated dropping support for alpha EV5 and earlier a while
  ago after noticing that this is the only supported CPU family in the
  kernel without native byte access and that Debian has already dropped
  support for this generation last year [1] in order to improve
  performance for the newer machines.

  This topic came up again when Paul McKenney noticed that parts of the
  RCU code already rely on byte access and do not work on alpha EV5
  reliably, so we decided on using my series to avoid the problem
  entirely.

  Al Viro did another series for alpha to address all the known build
  issues. I rebased his patches without any further changes and included
  it as a baseline for my work here to avoid conflicts and allow
  backporting the fixes to stable kernels for the now removed hardware
  support as well"

[ I dearly loved alpha back in the days, but the lack of byte and word
  operations was a horrible mistake and made everything worse -
  including very much the crazy IO contortions that resulted from it.

  It certainly wasn't the only mistake in the architecture, but it's the
  first-order issue.

  So while it's a bit sad to see the support for my first alpha go away,
  if you want to run museum hardware, maybe you should use museum
  kernels..    - Linus ]

   - Lots of updates for the Qualcomm platform drivers, in particular
     SCM, which gets a rewrite of its initialization code

   - Firmware driver updates for Arm FF-A notification interrupts and
     indirect messaging, SCMI firmware support for pin control and
     vendor specific interfaces, and TEE firmware interface changes
     across multiple TEE drivers

   - A larger cleanup of the Mediatek CMDQ driver and some related bits

   - Kconfig changes for riscv drivers to prepare for adding Kanaan k230
     support

      Linus Torvalds authored 
      Pull SoC devicetree updates from Arnd Bergmann:
 "The updates this time are a bit smaller than most times, mainly
  because it is not totally dominated by new Qualcomm hardware support.

  Instead, we larger than average updates for Rockchips, NXP, Allwinner
  and TI. The only two new SoCs this time are both from NXP and are
  minor variants of already supported ones.

  The updates for aspeed, amlogic and mediatek came a little late, so
  I'm saving those for part 2 in a few days if everything turns out
  fine.

  New machines this time contain:

   - two Broadcom SoC based wireless routers from Asus

   - Five allwinner based consumer devices for gaming, set-top-box and
     eboot reader applications

   - Three older phones based on Qualcomm chips, plus the more recent
     Sony Xperia 1 V

   - 14 industrial and embedded boards based on NXP i.MX6, i.MX8,
     layerscape and s32g3 SoCs

   - six rockchips boards including another handheld game console and a
     few single-board computers

  On top of these, we have the usual cleanups for dtc warnings and
  updates to add more features to already merged machines"

      Linus Torvalds authored 
      Pull s390 updates from Alexander Gordeev:

 - Store AP Query Configuration Information in a static buffer

 - Rework the AP initialization and add missing cleanups to the error
   path

 - Swap IRQ and AP bus/device registration to avoid race conditions

 - Export prot_virt_guest symbol

 - Introduce AP configuration changes notifier interface to facilitate
   modularization of the AP bus

 - Add CONFIG_AP kernel configuration option to allow modularization of
   the AP bus

 - Rework CONFIG_ZCRYPT_DEBUG kernel configuration option description
   and dependency and rename it to CONFIG_AP_DEBUG

 - Convert sprintf() and snprintf() to sysfs_emit() in CIO code

 - Adjust indentation of RELOCS command build step

 - Make crypto performance counters upward compatible

 - Convert make_page_secure() and gmap_make_secure() to use folio

 - Rework channel-utilization-block (CUB) handling in preparation of
   introducing additional CUBs

 - Use attribute groups to simplify registration, removal and extension
   of measurement-related channel-path sysfs attributes

 - Add a per-channel-path binary "ext_measurement" sysfs attribute that
   provides access to extended channel-path measurement data

 - Export measurement data for all channel-measurement-groups (CMG), not
   only for a specific ones. This enables support of new CMG data
   formats in userspace without the need for kernel changes

 - Add a per-channel-path sysfs attribute "speed_bps" that provides the
   operating speed in bits per second or 0 if the operating speed is not
   available

 - The CIO tracepoint subchannel-type field "st" is incorrectly set to
   the value of subchannel-enabled SCHIB "ena" field. Fix that

 - Do not forcefully limit vmemmap starting address to MAX_PHYSMEM_BITS

 - Consider the maximum physical address available to a DCSS segment
   (512GB) when memory layout is set up

 - Simplify the virtual memory layout setup by reducing the size of
   identity mapping vs vmemmap overlap

 - Swap vmalloc and Lowcore/Real Memory Copy areas in virtual memory.
   This will allow to place the kernel image next to kernel modules

 - Move everyting KASLR related from <asm/setup.h> to <asm/page.h>

 - Put virtual memory layout information into a structure to improve
   code generation

 - Currently __kaslr_offset is the kernel offset in both physical and
   virtual memory spaces. Uncouple these offsets to allow uncoupling of
   the addresses spaces

 - Currently the identity mapping base address is implicit and is always
   set to zero. Make it explicit by putting into __identity_base
   persistent boot variable and use it in proper context

 - Introduce .amode31 section start and end macros AMODE31_START and
   AMODE31_END

 - Introduce OS_INFO entries that do not reference any data in memory,
   but rather provide only values

 - Store virtual memory layout in OS_INFO. It is read out by
   makedumpfile, crash and other tools

 - Store virtual memory layout in VMCORE_INFO. It is read out by crash
   and other tools when /proc/kcore device is used

 - Create additional PT_LOAD ELF program header that covers kernel image
   only, so that vmcore tools could locate kernel text and data when
   virtual and physical memory spaces are uncoupled

 - Uncouple physical and virtual address spaces

 - Map kernel at fixed location when KASLR mode is disabled. The
   location is defined by CONFIG_KERNEL_IMAGE_BASE kernel configuration
   value.

 - Rework deployment of kernel image for both compressed and
   uncompressed variants as defined by CONFIG_KERNEL_UNCOMPRESSED kernel
   configuration value

 - Move .vmlinux.relocs section in front of the compressed kernel. The
   interim section rescue step is avoided as result

 - Correct modules thunk offset calculation when branch target is more
   than 2GB away

 - Kernel modules contain their own set of expoline thunks. Now that the
   kernel modules area is less than 4GB away from kernel expoline
   thunks, make modules use kernel expolines. Also make EXPOLINE_EXTERN
   the default if the compiler supports it

 - userfaultfd can insert shared zeropages into processes running VMs,
   but that is not allowed for s390. Fallback to allocating a fresh
   zeroed anonymous folio and insert that instead

 - Re-enable shared zeropages for non-PV and non-skeys KVM guests

 - Rename hex2bitmap() to ap_hex2bitmap() and export it for external use

 - Add ap_config sysfs attribute to provide the means for setting or
   displaying adapters, domains and control domains assigned to a
   vfio-ap mediated device in a single operation

 - Make vfio_ap_mdev_link_queue() ignore duplicate link requests

 - Add write support to ap_config sysfs attribute to allow atomic update
   a vfio-ap mediated device state

 - Document ap_config sysfs attribute

 - Function os_info_old_init() is expected to be called only from a
   regular kdump kernel. Enable it to be called from a stand-alone dump
   kernel

 - Address gcc -Warray-bounds warning and fix array size in struct
   os_info

 - s390 does not support SMBIOS, so drop unneeded CONFIG_DMI checks

 - Use unwinder instead of __builtin_return_address() with ftrace to
   prevent returning of undefined values

 - Sections .hash and .gnu.hash are only created when CONFIG_PIE_BUILD
   kernel is enabled. Drop these for the case CONFIG_PIE_BUILD is
   disabled

 - Compile kernel with -fPIC and link with -no-pie to allow kpatch
   feature always succeed and drop the whole CONFIG_PIE_BUILD
   option-enabled code

 - Add missing virt_to_phys() converter for VSIE facility and crypto
   control blocks
