34b21d1ddc mptcp: dedicated request sock for subflow in v6
tcp_request_sock_ops structure is specific to IPv4. It should then not
be used with MPTCP subflows on top of IPv6.

For example, it contains the 'family' field, initialised to AF_INET.
This 'family' field is used by TCP FastOpen code to generate the cookie
but also by TCP Metrics, SELinux and SYN Cookies. Using the wrong family
will not lead to crashes but displaying/using/checking wrong things.

Note that 'send_reset' callback from request_sock_ops structure is used
in some error paths. It is then also important to use the correct one
for IPv4 or IPv6.

The slab name can also be different in IPv4 and IPv6, it will be used
when printing some log messages. The slab pointer will anyway be the
same because the object size is the same for both v4 and v6. A
BUILD_BUG_ON() has also been added to make sure this size is the same.

3fff88186f mptcp: remove MPTCP 'ifdef' in TCP SYN cookies
To ease the maintenance, it is often recommended to avoid having #ifdef
preprocessor conditions.

Here the section related to CONFIG_MPTCP was quite short but the next
commit needs to add more code around. It is then cleaner to move
specific MPTCP code to functions located in net/mptcp directory.

Now that mptcp_subflow_request_sock_ops structure can be static, it can
also be marked as "read only after init".

da05cecc49 sctp: sysctl: make extra pointers netns aware
Recently, a customer reported that from their container whose
net namespace is different to the host's init_net, they can't set
the container's net.sctp.rto_max to any value smaller than
init_net.sctp.rto_min.

For instance,
Host:
sudo sysctl net.sctp.rto_min
net.sctp.rto_min = 1000

Container:
echo 100 > /mnt/proc-net/sctp/rto_min
echo 400 > /mnt/proc-net/sctp/rto_max
echo: write error: Invalid argument

This is caused by the check made from this'commit 4f3fdf3bc5
("sctp: add check rto_min and rto_max in sysctl")'
When validating the input value, it's always referring the boundary
value set for the init_net namespace.

Having container's rto_max smaller than host's init_net.sctp.rto_min
does make sense. Consider that the rto between two containers on the
same host is very likely smaller than it for two hosts.

So to fix this problem, as suggested by Marcelo, this patch makes the
extra pointers of rto_min, rto_max, pf_retrans, and ps_retrans point
to the corresponding variables from the newly created net namespace while
the new net namespace is being registered in sctp_sysctl_net_register.

5f7d78b2b1 ntb_netdev: Use dev_kfree_skb_any() in interrupt context
TX/RX callback handlers (ntb_netdev_tx_handler(),
ntb_netdev_rx_handler()) can be called in interrupt
context via the DMA framework when the respective
DMA operations have completed. As such, any calls
by these routines to free skb's, should use the
interrupt context safe dev_kfree_skb_any() function.

Previously, these callback handlers would call the
interrupt unsafe version of dev_kfree_skb(). This has
not presented an issue on Intel IOAT DMA engines as
that driver utilizes tasklets rather than a hard
interrupt handler, like the AMD PTDMA DMA driver.
On AMD systems, a kernel WARNING message is
encountered, which is being issued from
skb_release_head_state() due to in_hardirq()
being true.

Besides the user visible WARNING from the kernel,
the other symptom of this bug was that TCP/IP performance
across the ntb_netdev interface was very poor, i.e.
approximately an order of magnitude below what was
expected. With the repair to use dev_kfree_skb_any(),
kernel WARNINGs from skb_release_head_state() ceased
and TCP/IP performance, as measured by iperf, was on
par with expected results, approximately 20 Gb/s on
AMD Milan based server. Note that this performance
is comparable with Intel based servers.

0a1d4434db Updates for timers, timekeeping and drivers:
- Core:
 
    - The timer_shutdown[_sync]() infrastructure:
 
      Tearing down timers can be tedious when there are circular
      dependencies to other things which need to be torn down. A prime
      example is timer and workqueue where the timer schedules work and the
      work arms the timer.
 
      What needs to prevented is that pending work which is drained via
      destroy_workqueue() does not rearm the previously shutdown
      timer. Nothing in that shutdown sequence relies on the timer being
      functional.
 
      The conclusion was that the semantics of timer_shutdown_sync() should
      be:
 
 	- timer is not enqueued
     	- timer callback is not running
     	- timer cannot be rearmed
 
      Preventing the rearming of shutdown timers is done by discarding rearm
      attempts silently. A warning for the case that a rearm attempt of a
      shutdown timer is detected would not be really helpful because it's
      entirely unclear how it should be acted upon. The only way to address
      such a case is to add 'if (in_shutdown)' conditionals all over the
      place. This is error prone and in most cases of teardown not required
      all.
 
    - The real fix for the bluetooth HCI teardown based on
      timer_shutdown_sync().
 
      A larger scale conversion to timer_shutdown_sync() is work in

369013162f A set of changes for the x86 APIC code:
- Handle the case where x2APIC is enabled and locked by the BIOS on a
     kernel with CONFIG_X86_X2APIC=n gracefully. Instead of a panic which
     does not make it to the graphical console during very early boot,
     simply disable the local APIC completely and boot with the PIC and very
     limited functionality, which allows to diagnose the issue.
 
   - Convert x86 APIC device tree bindings to YAML
 
   - Extend x86 APIC device tree bindings to configure interrupt delivery
     mode and handle this in during init. This allows to boot with device
     tree on platforms which lack a legacy PIC.

9d33edb20f Updates for the interrupt core and driver subsystem:
- Core:
 
    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
    contrary to the uniform and specification defined storage mechanisms for
    PCI/MSI and PCI/MSI-X. 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 stranglers
    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.

  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.

   - Updates for the LoongArch interrupt chip drivers

   - Support for MTK CIRQv2

   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().

Merge tag 's390-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

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%)

01f3cbb296 SoC: DT changes for 6.2
The devicetree changes contain exactly 1000 non-merge changesets,
 including a number of new arm64 SoC variants from Qualcomm and Apple,
 as well as the Renesas r9a07g043f/u chip in both arm64 and riscv variants
 While we have occasionally merged support for non-arm SoCs in the past,
 this is now the normal path for riscv devicetree files.
 
 The most notable changes, by SoC platform, are:
 
  - The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M2 Ultra)
    chips 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.

8e17b16a2c SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
 reworks and support for variants of the existing SoC.  While this remains
 Arm centric for the most part, the branch now also contains updates to
 risc-v and loongarch specific code in drivers/soc/.
 
 Notable changes include:
 
  - Support for the newly added Qualcomm Snapdragon variants
    (MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
    soc ID, rpmh, rpm, spm and powerdomain drivers.
 
  - Documentation for the somewhat controversial qcom,board-id
    properties that are required for booting a number of machines
 
  - A new SoC identification driver for the loongson-2 (loongarch)
    platform
 
  - memory controller updates for stm32, tegra, and renesas.
 
  - a new DT binding to better describe LPDDR2/3/4/5 chips in
    the memory controller subsystem
 
  - Updates for Tegra specific drivers across multiple subsystems,
    improving support for newer SoCs and better identification
 
  - Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
    TI, Mediatek and Marvell SoC drivers

Merge tag 'slab-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

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.

 - Miscellaneous improvements/fixes:
     - __alloc_size checking compiler workaround (Kees Cook)
     - Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes)
     - Make SLAB compatible with PROVE_RAW_LOCK_NESTING (Jiri Kosina)
     - Correct SLUB's percpu allocation estimates (Baoquan He)
     - Re-enableS LUB's run-time failslab sysfs control (Alexander Atanasov)

Merge tag 'printk-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

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

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:

    648060902a ("MIPS: pic32: treat port as signed integer")
    5c26159c97 ("ipvs: use explicitly signed chars")
    e6cb876945 ("wifi: airo: do not assign -1 to unsigned char")
    937ec9f7d5 ("staging: rtl8192e: remove bogus ssid character sign test")
    6770473832 ("misc: sgi-gru: use explicitly signed char")
    50895a55bc ("ALSA: rme9652: use explicitly signed char")
    ee03c0f200 ("ALSA: au88x0: use explicitly signed char")
    835bed1b83 ("fbdev: sisfb: use explicitly signed char")
    50f19697dd ("parisc: Use signed char for hardware path in pdc.h")
    66063033f7 ("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"
