Pull irq updates from Thomas Gleixner:
 "Updates for the interrupt core and driver subsystem:

  The bulk is the rework of the MSI subsystem to support per device MSI
  interrupt domains. This solves conceptual problems of the current
  PCI/MSI design which are in the way of providing support for
  PCI/MSI[-X] and the upcoming PCI/IMS mechanism on the same device.

  IMS (Interrupt Message Store] is a new specification which allows
  device manufactures to provide implementation defined storage for MSI
  messages (as opposed to PCI/MSI and PCI/MSI-X that has a specified
  message store which is uniform accross all devices). The PCI/MSI[-X]
  uniformity allowed us to get away with "global" PCI/MSI domains.

  IMS not only allows to overcome the size limitations of the MSI-X
  table, but also gives the device manufacturer the freedom to store the
  message in arbitrary places, even in host memory which is shared with
  the device.

  There have been several attempts to glue this into the current MSI
  code, but after lengthy discussions it turned out that there is a
  fundamental design problem in the current PCI/MSI-X implementation.
  This needs some historical background.

  When PCI/MSI[-X] support was added around 2003, interrupt management
  was completely different from what we have today in the actively
  developed architectures. Interrupt management was completely
  architecture specific and while there were attempts to create common
  infrastructure the commonalities were rudimentary and just providing
  shared data structures and interfaces so that drivers could be written
  in an architecture agnostic way.

  The initial PCI/MSI[-X] support obviously plugged into this model
  which resulted in some basic shared infrastructure in the PCI core
  code for setting up MSI descriptors, which are a pure software
  construct for holding data relevant for a particular MSI interrupt,
  but the actual association to Linux interrupts was completely
  architecture specific. This model is still supported today to keep
  museum architectures and notorious stragglers alive.

  In 2013 Intel tried to add support for hot-pluggable IO/APICs to the
  kernel, which was creating yet another architecture specific mechanism
  and resulted in an unholy mess on top of the existing horrors of x86
  interrupt handling. The x86 interrupt management code was already an
  incomprehensible maze of indirections between the CPU vector
  management, interrupt remapping and the actual IO/APIC and PCI/MSI[-X]
  implementation.

  At roughly the same time ARM struggled with the ever growing SoC
  specific extensions which were glued on top of the architected GIC
  interrupt controller.

  This resulted in a fundamental redesign of interrupt management and
  provided the today prevailing concept of hierarchical interrupt
  domains. This allowed to disentangle the interactions between x86
  vector domain and interrupt remapping and also allowed ARM to handle
  the zoo of SoC specific interrupt components in a sane way.

  The concept of hierarchical interrupt domains aims to encapsulate the
  functionality of particular IP blocks which are involved in interrupt
  delivery so that they become extensible and pluggable. The X86
  encapsulation looks like this:

                                            |--- device 1
     [Vector]---[Remapping]---[PCI/MSI]--|...
                                            |--- device N

  where the remapping domain is an optional component and in case that
  it is not available the PCI/MSI[-X] domains have the vector domain as
  their parent. This reduced the required interaction between the
  domains pretty much to the initialization phase where it is obviously
  required to establish the proper parent relation ship in the
  components of the hierarchy.

  While in most cases the model is strictly representing the chain of IP
  blocks and abstracting them so they can be plugged together to form a
  hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the
  hardware it's clear that the actual PCI/MSI[-X] interrupt controller
  is not a global entity, but strict a per PCI device entity.

  Here we took a short cut on the hierarchical model and went for the
  easy solution of providing "global" PCI/MSI domains which was possible
  because the PCI/MSI[-X] handling is uniform across the devices. This
  also allowed to keep the existing PCI/MSI[-X] infrastructure mostly
  unchanged which in turn made it simple to keep the existing
  architecture specific management alive.

  A similar problem was created in the ARM world with support for IP
  block specific message storage. Instead of going all the way to stack
  a IP block specific domain on top of the generic MSI domain this ended
  in a construct which provides a "global" platform MSI domain which
  allows overriding the irq_write_msi_msg() callback per allocation.

  In course of the lengthy discussions we identified other abuse of the
  MSI infrastructure in wireless drivers, NTB etc. where support for
  implementation specific message storage was just mindlessly glued into
  the existing infrastructure. Some of this just works by chance on
  particular platforms but will fail in hard to diagnose ways when the
  driver is used on platforms where the underlying MSI interrupt
  management code does not expect the creative abuse.

  Another shortcoming of today's PCI/MSI-X support is the inability to
  allocate or free individual vectors after the initial enablement of
  MSI-X. This results in an works by chance implementation of VFIO (PCI
  pass-through) where interrupts on the host side are not set up upfront
  to avoid resource exhaustion. They are expanded at run-time when the
  guest actually tries to use them. The way how this is implemented is
  that the host disables MSI-X and then re-enables it with a larger
  number of vectors again. That works by chance because most device
  drivers set up all interrupts before the device actually will utilize
  them. But that's not universally true because some drivers allocate a
  large enough number of vectors but do not utilize them until it's
  actually required, e.g. for acceleration support. But at that point
  other interrupts of the device might be in active use and the MSI-X
  disable/enable dance can just result in losing interrupts and
  therefore hard to diagnose subtle problems.

  Last but not least the "global" PCI/MSI-X domain approach prevents to
  utilize PCI/MSI[-X] and PCI/IMS on the same device due to the fact
  that IMS is not longer providing a uniform storage and configuration
  model.

  The solution to this is to implement the missing step and switch from
  global PCI/MSI domains to per device PCI/MSI domains. The resulting
  hierarchy then looks like this:

                              |--- [PCI/MSI] device 1
     [Vector]---[Remapping]---|...
                              |--- [PCI/MSI] device N

  which in turn allows to provide support for multiple domains per
  device:

                              |--- [PCI/MSI] device 1
                              |--- [PCI/IMS] device 1
     [Vector]---[Remapping]---|...
                              |--- [PCI/MSI] device N
                              |--- [PCI/IMS] device N

  This work converts the MSI and PCI/MSI core and the x86 interrupt
  domains to the new model, provides new interfaces for post-enable
  allocation/free of MSI-X interrupts and the base framework for
  PCI/IMS. PCI/IMS has been verified with the work in progress IDXD
  driver.

  There is work in progress to convert ARM over which will replace the
  platform MSI train-wreck. The cleanup of VFIO, NTB and other creative
  "solutions" are in the works as well.

Pull s390 updates from Alexander Gordeev:

 - Factor out handle_write() function and simplify 3215 console write
   operation

 - When 3170 terminal emulator is connected to the 3215 console driver
   the boot time could be very long due to limited buffer space or
   missing operator input. Add con3215_drop command line parameter and
   con3215_drop sysfs attribute file to instruct the kernel drop console
   data when such conditions are met

 - Fix white space errors in 3215 console driver

 - Move enum paiext_mode definition to a header file and rename it to
   paievt_mode to indicate this is now used for several events. Rename
   PAI_MODE_COUNTER to PAI_MODE_COUNTING to make consistent with
   PAI_MODE_SAMPLING

 - Simplify the logic of PMU pai_crypto mapped buffer reference counter
   and make it consistent with PMU pai_ext

 - Rename PMU pai_crypto mapped buffer structure member users to
   active_events to make it consistent with PMU pai_ext

 - Enable HUGETLB_PAGE_OPTIMIZE_VMEMMAP configuration option. This
   results in saving of 12K per 1M hugetlb page (~1.2%) and 32764K per
   2G hugetlb page (~1.6%)

 - Use generic serial.h, bugs.h, shmparam.h and vga.h header files and
   scrap s390-specific versions

 - The generic percpu setup code does not expect the s390-like
   implementation and emits a warning. To get rid of that warning and
   provide sane CPU-to-node and CPU-to-CPU distance mappings implementat
   a minimal version of setup_per_cpu_areas()

 - Use kstrtobool() instead of strtobool() for re-IPL sysfs device
   attributes

 - Avoid unnecessary lookup of a pointer to MSI descriptor when setting
   IRQ affinity for a PCI device

 - Get rid of "an incompatible function type cast" warning by changing
   debug_sprintf_format_fn() function prototype so it matches the
   debug_format_proc_t function type

 - Remove unused info_blk_hdr__pcpus() and get_page_state() functions

 - Get rid of clang "unused unused insn cache ops function" warning by
   moving s390_insn definition to a private header

 - Get rid of clang "unused function" warning by making function
   raw3270_state_final() only available if CONFIG_TN3270_CONSOLE is
   enabled

 - Use kstrobool() to parse sclp_con_drop parameter to make it identical
   to the con3215_drop parameter and allow passing values like "yes" and
   "true"

 - Use sysfs_emit() for all SCLP sysfs show functions, which is the
   current standard way to generate output strings

 - Make SCLP con_drop sysfs attribute also writable and allow to change
   its value during runtime. This makes SCLP console drop handling
   consistent with the 3215 device driver

 - Virtual and physical addresses are indentical on s390. However, there
   is still a confusion when pointers are directly casted to physical
   addresses or vice versa. Use correct address converters
   virt_to_phys() and phys_to_virt() for s390 channel IO drivers

 - Support for power managemant has been removed from s390 since quite
   some time. Remove unused power managemant code from the appldata
   device driver

 - Allow memory tools like KASAN see memory accesses from the checksum
   code. Switch to GENERIC_CSUM if KASAN is enabled, just like x86 does

 - Add support of ECKD DASDs disks so it could be used as boot and dump
   devices

 - Follow checkpatch recommendations and use octal values instead of
   S_IRUGO and S_IWUSR for dump device attributes in sysfs

 - Changes to vx-insn.h do not cause a recompile of C files that use
   asm(".include \"asm/vx-insn.h\"\n") magic to access vector
   instruction macros from inline assemblies. Add wrapper include header
   file to avoid this problem

 - Use vector instruction macros instead of byte patterns to increase
   register validation routine readability

 - The current machine check register validation handling does not take
   into account various scenarios and might lead to killing a wrong user
   process or potentially ignore corrupted FPU registers. Simplify logic
   of the machine check handler and stop the whole machine if the
   previous context was kerenel mode. If the previous context was user
   mode, kill the current task

 - Introduce sclp_emergency_printk() function which can be used to emit
   a message in emergency cases. It is supposed to be used in cases
   where regular console device drivers may not work anymore, e.g.
   unrecoverable machine checks

   Keep the early Service-Call Control Block so it can also be used
   after initdata has been freed to allow sclp_emergency_printk()
   implementation

 - In case a system will be stopped because of an unrecoverable machine
   check error print the machine check interruption code to give a hint
   of what went wrong

 - Move storage error checking from the assembly entry code to C in
   order to simplify machine check handling. Enter the handler with DAT
   turned on, which simplifies the entry code even more

 - The machine check extended save areas are allocated using a private
   "nmi_save_areas" slab cache which guarantees a required power-of-two
   alignment. Get rid of that cache in favour of kmalloc()

     now have initial support. This is particularly nice as I am typing
     this on a T6002 Mac Studio with only a small number of driver
     patches.

   - Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662),
     SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670
     (Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon
     650) are all mobile phone chips that are closely related to others
     we already support.

     Adding those helps support more phones and we add several models
     from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3,
     3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and
     Google (Pixel 3a).

     There are also new variants of the Herobrine and Trogdor chromebook
     motherboards. SA8540P is an automotive SoC used in the Qdrive-3
     development platform

   - Rockchips gains no new SoC variants, but a lot of new boards: three
     mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two
     more Anbernic gaming systems based on RK3566 and a number of other
     RK356x based single-board computers.

   - Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as
     the newly added RZ/Five is based on the same design, this now gets
     reorganized in order to share most of the dts description between
     the two and add the RZ/Five SMARC EVK board support.

  Aside from that, there are the usual changes all over the tree:

   - New boards on other platforms contain two ASpeed BMC users, two
     Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based
     Kobo Aura2 ebook reader, two i.MX8 based development boards, two
     Uniphier Pro5 development boards, the STM32MP1 testbench board from
     DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek
     Helio X10 based Sony Xperia M5 phone.

   - The Starfive JH7100 source gets reorganized in order to support the
     VisionFive V1 board.

   - Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI,
     ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton,
     Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500,
     spear, ... The treewide cleanups now have a lot of fixes for cache
     nodes and other binding violoations.

   - Somewhat larger sets of reworks for NVIDIA Tegra, Qualcomm and
     Renesas platforms, adding a lot more on-chip device support

   - A rework of the way that DTB overlays are built"

Pull arm64 updates from Will Deacon:
 "The highlights this time are support for dynamically enabling and
  disabling Clang's Shadow Call Stack at boot and a long-awaited
  optimisation to the way in which we handle the SVE register state on
  system call entry to avoid taking unnecessary traps from userspace.

  Summary:

  ACPI:
   - Enable FPDT support for boot-time profiling
   - Fix CPU PMU probing to work better with PREEMPT_RT
   - Update SMMUv3 MSI DeviceID parsing to latest IORT spec
   - APMT support for probing Arm CoreSight PMU devices

  CPU features:
   - Advertise new SVE instructions (v2.1)
   - Advertise range prefetch instruction
   - Advertise CSSC ("Common Short Sequence Compression") scalar
     instructions, adding things like min, max, abs, popcount
   - Enable DIT (Data Independent Timing) when running in the kernel
   - More conversion of system register fields over to the generated
     header

  CPU misfeatures:
   - Workaround for Cortex-A715 erratum #2645198

  Dynamic SCS:
   - Support for dynamic shadow call stacks to allow switching at
     runtime between Clang's SCS implementation and the CPU's pointer
     authentication feature when it is supported (complete with scary
     DWARF parser!)

  Tracing and debug:
   - Remove static ftrace in favour of, err, dynamic ftrace!
   - Seperate 'struct ftrace_regs' from 'struct pt_regs' in core ftrace
     and existing arch code
   - Introduce and implement FTRACE_WITH_ARGS on arm64 to replace the
     old FTRACE_WITH_REGS
   - Extend 'crashkernel=' parameter with default value and fallback to
     placement above 4G physical if initial (low) allocation fails

  SVE:
   - Optimisation to avoid disabling SVE unconditionally on syscall
     entry and just zeroing the non-shared state on return instead

  Exceptions:
   - Rework of undefined instruction handling to avoid serialisation on
     global lock (this includes emulation of user accesses to the ID
     registers)

  Perf and PMU:
   - Support for TLP filters in Hisilicon's PCIe PMU device
   - Support for the DDR PMU present in Amlogic Meson G12 SoCs
   - Support for the terribly-named "CoreSight PMU" architecture from
     Arm (and Nvidia's implementation of said architecture)

  Misc:
   - Tighten up our boot protocol for systems with memory above 52 bits
     physical
   - Const-ify static keys to satisty jump label asm constraints
   - Trivial FFA driver cleanups in preparation for v1.1 support
   - Export the kernel_neon_* APIs as GPL symbols
   - Harden our instruction generation routines against instrumentation
   - A bunch of robustness improvements to our arch-specific selftests
   - Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)"

Pull slab updates from Vlastimil Babka:

 - SLOB deprecation and SLUB_TINY

   The SLOB allocator adds maintenance burden and stands in the way of
   API improvements [1]. Deprecate it by renaming the config option (to
   make users notice) to CONFIG_SLOB_DEPRECATED with updated help text.
   SLUB should be used instead as SLAB will be the next on the removal
   list.

   Based on reports from a riscv k210 board with 8MB RAM, add a
   CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the
   expense of scalability. This has resolved the k210 regression [2] so
   in case there are no others (that wouldn't be resolvable by further
   tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.

   Existing defconfigs with CONFIG_SLOB are converted to
   CONFIG_SLUB_TINY.

 - kmalloc() slub_debug redzone improvements

   A series from Feng Tang that builds on the tracking or requested size
   for kmalloc() allocations (for caches with debugging enabled) added
   in 6.1, to make redzone checks consider the requested size and not
   the rounded up one, in order to catch more subtle buffer overruns.
   Includes new slub_kunit test.

 - struct slab fields reordering to accomodate larger rcu_head

   RCU folks would like to grow rcu_head with debugging options, which
   breaks current struct slab layout's assumptions, so reorganize it to
   make this possible.

Pull printk updates from Petr Mladek:

 - Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
   this_cpu_inc() on strong load-store architectures.

 - Introduce new console_list_lock to synchronize a manipulation of the
   list of registered consoles and their flags.

   This is a first step in removing the big-kernel-lock-like behavior of
   console_lock(). This semaphore still serializes console->write()
   calbacks against:

      - each other. It primary prevents potential races between early
        and proper console drivers using the same device.

      - suspend()/resume() callbacks and init() operations in some
        drivers.

      - various other operations in the tty/vt and framebufer
        susbsystems. It is likely that console_lock() serializes even
        operations that are not directly conflicting with the
        console->write() callbacks here. This is the most complicated
        big-kernel-lock aspect of the console_lock() that will be hard
        to untangle.

 - Introduce new console_srcu lock that is used to safely iterate and
   access the registered console drivers under SRCU read lock.

   This is a prerequisite for introducing atomic console drivers and
   console kthreads. It will reduce the complexity of serialization
   against normal consoles and console_lock(). Also it should remove the
   risk of deadlock during critical situations, like Oops or panic, when
   only atomic consoles are registered.

 - Check whether the console is registered instead of enabled on many
   locations. It was a historical leftover.

 - Cleanly force a preferred console in xenfb code instead of a dirty
   hack.

 - A lot of code and comment clean ups and improvements.

Pull file locking updates from Jeff Layton:
 "The main change here is to add the new locks_inode_context helper, and
  convert all of the places that dereference inode->i_flctx directly to
  use that instead.

  There is a new helper to indicate whether any locks are held on an
  inode. This is mostly for Ceph but may be usable elsewhere too.

  Andi Kleen requested that we print the PID when the LOCK_MAND warning
  fires, to help track down applications trying to use it.

  Finally, we added some new warnings to some of the file locking
  functions that fire when the ->fl_file and filp arguments differ. This
  helped us find some long-standing bugs in lockd. Patches for those are
  in Chuck Lever's tree and should be in his v6.2 PR. After that patch,
  people using NFSv2/v3 locking may see some warnings fire until those
  go in.

Pull unsigned-char conversion from Jason Donenfeld:
 "Enable -funsigned-char and fix code affected by that flag.

  During the 6.1 cycle, several patches already made it into the tree,
  which were for code that was already broken on at least one
  architecture, where the naked char had a different sign than the code
  author anticipated, or were part of some bug fix for an existing bug
  that this initiative unearthed.

  These 6.1-era fixes are:

    64806090 ("MIPS: pic32: treat port as signed integer")
    5c26159c ("ipvs: use explicitly signed chars")
    e6cb8769 ("wifi: airo: do not assign -1 to unsigned char")
    937ec9f7 ("staging: rtl8192e: remove bogus ssid character sign test")
    67704738 ("misc: sgi-gru: use explicitly signed char")
    50895a55 ("ALSA: rme9652: use explicitly signed char")
    ee03c0f2 ("ALSA: au88x0: use explicitly signed char")
    835bed1b ("fbdev: sisfb: use explicitly signed char")
    50f19697 ("parisc: Use signed char for hardware path in pdc.h")
    66063033 ("wifi: rt2x00: use explicitly signed or unsigned types")

  Regarding patches in this pull:

   - There is one patch in this pull that should have made it to you
     during 6.1 ("media: stv0288: use explicitly signed char"), but the
     maintainer was MIA during the cycle, so it's in here instead.

   - Two patches fix single architecture code affected by unsigned char
     ("perf/x86: Make struct p4_event_bind::cntr signed array" and
     "sparc: sbus: treat CPU index as integer"), while one patch fixes
     an unused typedef, in case it's ever used in the future ("media:
     atomisp: make hive_int8 explictly signed").

   - Finally, there's the change to actually enable -funsigned-char
     ("kbuild: treat char as always unsigned") and then the removal of
     some no longer useful !__CHAR_UNSIGNED__ selftest code ("lib:
     assume char is unsigned").

  The various fixes were found with a combination of diffing objdump
  output, a large variety of Coccinelle scripts, and plain old grep. In
  the end, things didn't seem as bad as I feared they would. But of
  course, it's also possible I missed things.

  However, this has been in linux-next for basically an entire cycle
  now, so I'm not overly worried. I've also been daily driving this on
  my laptop for all of 6.1. Still, this series, and the ones sent for
  6.1 don't total in quantity to what I thought it'd be, so I will be on
  the lookout for breakage.

  We could receive a few reports that are quickly fixable. Hopefully we
  won't receive a barrage of reports that would result in a revert. And
  just maybe we won't receive any reports at all and nobody will even
  notice. Knock on wood"

Pull RCU updates from Paul McKenney:

 - Documentation updates. This is the second in a series from an ongoing
   review of the RCU documentation.

 - Miscellaneous fixes.

 - Introduce a default-off Kconfig option that depends on RCU_NOCB_CPU
   that, on CPUs mentioned in the nohz_full or rcu_nocbs boot-argument
   CPU lists, causes call_rcu() to introduce delays.

   These delays result in significant power savings on nearly idle
   Android and ChromeOS systems. These savings range from a few percent
   to more than ten percent.

   This series also includes several commits that change call_rcu() to a
   new call_rcu_hurry() function that avoids these delays in a few
   cases, for example, where timely wakeups are required. Several of
   these are outside of RCU and thus have acks and reviews from the
   relevant maintainers.

 - Create an srcu_read_lock_nmisafe() and an srcu_read_unlock_nmisafe()
   for architectures that support NMIs, but which do not provide
   NMI-safe this_cpu_inc(). These NMI-safe SRCU functions are required
   by the upcoming lockless printk() work by John Ogness et al.

 - Changes providing minor but important increases in torture test
   coverage for the new RCU polled-grace-period APIs.

 - Changes to torturescript that avoid redundant kernel builds, thus
   providing about a 30% speedup for the torture.sh acceptance test.

  ARM: 9278/1: kfence: only handle translation faults

memcg_write_event_control() accesses the dentry->d_name of the specified
control fd to route the write call.  As a cgroup interface file can't be
renamed, it's safe to access d_name as long as the specified file is a
regular cgroup file.  Also, as these cgroup interface files can't be
removed before the directory, it's safe to access the parent too.

Prior to 347c4a87 ("memcg: remove cgroup_event->cft"), there was a
call to __file_cft() which verified that the specified file is a regular
cgroupfs file before further accesses.  The cftype pointer returned from
__file_cft() was no longer necessary and the commit inadvertently dropped
the file type check with it allowing any file to slip through.  With the
invarients broken, the d_name and parent accesses can now race against
renames and removals of arbitrary files and cause use-after-free's.

Fix the bug by resurrecting the file type check in __file_cft().  Now that
cgroupfs is implemented through kernfs, checking the file operations needs
to go through a layer of indirection.  Instead, let's check the superblock
and dentry type.

For dax pud, pud_huge() returns true on x86. So the function works as long
as hugetlb is configured. However, dax doesn't depend on hugetlb.
Commit 414fd080 ("mm/gup: fix gup_pmd_range() for dax") fixed
devmap-backed huge PMDs, but missed devmap-backed huge PUDs. Fix this as
well.

This fixes the below kernel panic:

Add more sanity checks to the VMA that do_brk_flags() will expand.  Ensure
the VMA matches basic merge requirements within the function before
calling can_vma_merge_after().

Drop the duplicate checks from vm_brk_flags() since they will be enforced
later.

The old code would expand file VMAs on brk(), which is functionally
wrong and also dangerous in terms of locking because the brk() path
isn't designed for file VMAs and therefore doesn't lock the file
mapping.  Checking can_vma_merge_after() ensures that new anonymous
VMAs can't be merged into file VMAs.
