Nhat Pham 88537aac0b selftests: add selftests for cachestat
Test cachestat on a newly created file, /dev/ files, /proc/ files and a
directory.  Also test on a shmem file (which can also be tested with
huge pages since tmpfs supports huge pages).

Nicholas Piggin 7cc99ed87e KVM: PPC: Update MAINTAINERS
Michael is merging KVM PPC patches via the powerpc tree and KVM topic
branches. He doesn't necessarily have time to be across all of KVM so
is reluctant to call himself maintainer, but for the mechanics of how
patches flow upstream, it is maintained and does make sense to have
some contact people in MAINTAINERS.

So add Michael Ellerman as KVM PPC maintainer and myself as reviewer.
Split out the subarchs that don't get so much attention.

Nishanth Menon 32a2e6ab2c dt-bindings: pinctrl: Drop k3
For convenience (less code duplication), the pin controller pin
configuration register values were defined in the bindings header.
These are not some IDs or other abstraction layer but raw numbers used
in the registers.

These constants do not fit the purpose of bindings. They do not
provide any abstraction, any hardware and driver independent ID. In
fact, the Linux pinctrl-single driver actually do not use the bindings
header at all.

Commit f2de003e14 ("dt-bindings: pinctrl: k3: Deprecate header with
register constants") already moved users to the local header, so, drop
the binding header. See background discussion in [1].

While at it, clean up the MAINTAINERS file which is the only reference
left.

William Breathitt Gray d428487471 counter: i8254: Introduce the Intel 8254 interface library module
Exposes consumer library functions providing support for interfaces
compatible with the venerable Intel 8254 Programmable Interval Timer
(PIT).

The Intel 8254 PIT first appeared in the early 1980s and was used
initially in IBM PC compatibles. The popularity of the original Intel
825x family of chips led to many subsequent variants and clones of the
interface in various chips and integrated circuits. Although still
popular, interfaces compatible with the Intel 8254 PIT are nowdays
typically found embedded in larger VLSI processing chips and FPGA
components rather than as discrete ICs.

A CONFIG_I8254 Kconfig option is introduced by this patch. Modules
wanting access to these i8254 library functions should select this
Kconfig option, and import the I8254 symbol namespace.

James Seo 23902f98f8 hwmon: add HP WMI Sensors driver
Hewlett-Packard (and some HP Compaq) business-class computers report
hardware monitoring information via WMI. This driver exposes that
information to hwmon.

Initial support is provided for temperature, fan speed, and intrusion
sensor types. Provisional support is provided for voltage and current
sensor types.

HP's WMI implementation permits many other types of numeric sensors.
Therefore, a debugfs interface is also provided to enumerate and
inspect all numeric sensors visible on the WMI side. This should
facilitate adding support for other sensor types in the future.

Tested on a HP Z420, a HP EliteOne 800 G1, and a HP Compaq Elite 8300
SFF.

Note that provisionally supported sensor types are untested and seem
to be rare-to-nonexistent in the wild, having been encountered
neither on test systems nor in ACPI dumps from the Linux Hardware
Database. They are included because their popularity in general makes
their presence on past or future HP systems plausible and because no
doubt exists as to how the sensors themselves would be represented in
WMI (alarm attributes will need to wait for hardware to be located).
A 2005 HP whitepaper gives the relevant sensor object MOF definition
and sensor value scaling calculation, and both this driver and the
official HP Performance Advisor utility comply with them (confirmed
in the latter case by reverse engineering).

Ivan Orlov 315a3d57c6 ALSA: Implement the new Virtual PCM Test Driver
We have a lot of different virtual media drivers, which can be used for
testing of the userspace applications and media subsystem middle layer.
However, all of them are aimed at testing the video functionality and
simulating the video devices. For audio devices we have only snd-dummy
module, which is good in simulating the correct behavior of an ALSA device.
I decided to write a tool, which would help to test the userspace ALSA
programs (and the PCM middle layer as well) under unusual circumstances
to figure out how they would behave. So I came up with this Virtual PCM
Test Driver.

This new Virtual PCM Test Driver has several features which can be useful
during the userspace ALSA applications testing/fuzzing, or testing/fuzzing
of the PCM middle layer. Not all of them can be implemented using the
existing virtual drivers (like dummy or loopback). Here is what can this
driver do:

- Simulate both capture and playback processes
- Generate random or pattern-based capture data
- Inject delays into the playback and capturing processes
- Inject errors during the PCM callbacks

Also, this driver can check the playback stream for containing the
predefined pattern, which is used in the corresponding selftest to check
the PCM middle layer data transferring functionality. Additionally, this
driver redefines the default RESET ioctl, and the selftest covers this PCM
API functionality as well.

The driver supports both interleaved and non-interleaved access modes, and
have separate pattern buffers for each channel. The driver supports up to
4 channels and up to 8 substreams.

Documentation/process: add soc maintainer handbook
Arnd suggested that adding a maintainer handbook for the SoC "subsystem"
would be helpful in trying to bring on board maintainers for the various
new platforms cropping up in RISC-V land.

Add a document briefly describing the role of the SoC subsystem and some
basic advice for (new) platform maintainers.

Maxime Chevallier 196eec4062 net: pcs: Drop the TSE PCS driver
Now that we can easily create a mdio-device that represents a
memory-mapped device that exposes an MDIO-like register layout, we don't
need the Altera TSE PCS anymore, since we can use the Lynx PCS instead.

Maxime Chevallier 642af0f92c net: mdio: Introduce a regmap-based mdio driver
There exists several examples today of devices that embed an ethernet
PHY or PCS directly inside an SoC. In this situation, either the device
is controlled through a vendor-specific register set, or sometimes
exposes the standard 802.3 registers that are typically accessed over
MDIO.

As phylib and phylink are designed to use mdiodevices, this driver
allows creating a virtual MDIO bus, that translates mdiodev register
accesses to regmap accesses.

The reason we use regmap is because there are at least 3 such devices
known today, 2 of them are Altera TSE PCS's, memory-mapped, exposed
with a 4-byte stride in stmmac's dwmac-socfpga variant, and a 2-byte
stride in altera-tse. The other one (nxp,sja1110-base-tx-mdio) is
exposed over SPI.

Linus Torvalds 18713e8a68 ARM: SoC fixes for 6.4
There have not been a lot of fixes for for the soc tree in 6.4, but
 these have been sitting here for too long.
 
 For the devicetree side, there is one minor warning fix for vexpress,
 the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
 for the iMX8 clocks and its USB-3.0 gadget device, as well as board
 specific fixes for regulators and the phy on some of the i.MX boards.
 
 The microchip risc-v and arm32 maintainers now also add a shared
 maintainer file entry for the arm64 parts.
 
 The remaining fixes are all for firmware drivers, addressing mistakes in
 the optee, scmi and ff-a firmware driver implementation, mostly in the
 error handling code, incorrect use of the alloc_workqueue() interface in
 SCMI, and compatibility with corner cases of the firmware implementation.

Pull vfs fixes from Christian Brauner:

 - During the acl rework we merged this cycle the generic_listxattr()
   helper had to be modified in a way that in principle it would allow
   for POSIX ACLs to be reported. At least that was the impression we
   had initially. Because before the acl rework POSIX ACLs would be
   reported if the filesystem did have POSIX ACL xattr handlers in
   sb->s_xattr. That logic changed and now we can simply check whether
   the superblock has SB_POSIXACL set and if the inode has
   inode->i_{default_}acl set report the appropriate POSIX ACL name.

   However, we didn't realize that generic_listxattr() was only ever
   used by two filesystems. Both of them don't support POSIX ACLs via
   sb->s_xattr handlers and so never reported POSIX ACLs via
   generic_listxattr() even if they raised SB_POSIXACL and did contain
   inodes which had acls set. The example here is nfs4.

   As a result, generic_listxattr() suddenly started reporting POSIX
   ACLs when it wouldn't have before. Since SB_POSIXACL implies that the
   umask isn't stripped in the VFS nfs4 can't just drop SB_POSIXACL from
   the superblock as it would also alter umask handling for them.

   So just have generic_listxattr() not report POSIX ACLs as it never
   did anyway. It's documented as such.

 - Our SB_* flags currently use a signed integer and we shift the last
   bit causing UBSAN to complain about undefined behavior. Switch to
   using unsigned. While the original patch used an explicit unsigned
   bitshift it's now pretty common to rely on the BIT() macro in a lot
   of headers nowadays. So the patch has been adjusted to use that.

 - Add Namjae as ntfs reviewer. They're already active this cycle so
   let's make it explicit right now.

Krzysztof noticed that patches for arch/arm64/boot/dts/microchip were
getting lost & the listed tree was inactive.

Nicolas and I are willing to shepherd patches to Arnd, using the
existing at91 tree, so add a new entry covering
arch/arm64/boot/dts/microchip, listing us as maintainers.

Drop the tree from the existing sparx5 entry & narrow the devicetree
pattern to just sparx devices, leaving Lars, Steen and Daniel looking
after support for their SoCs.

It's hard to keep track of changes to the process docs.
Subsystem maintainers should probably know what's going on,
to ensure reasonably uniform developer experience across
trees.

We also need a place where process discussions can be held
(i.e. designated mailing list which can be CCed on naturally
arising discussions). I'm using workflows@ in this RFC,
but a new list may be better.

Lukas Bulwahn ee4d21aa4a MAINTAINERS: remove broken entries in QUALCOMM TYPEC PORT MANAGER DRIVER
Commit a4422ff221 ("usb: typec: qcom: Add Qualcomm PMIC Type-C driver")
adds the section QUALCOMM TYPEC PORT MANAGER DRIVER in MAINTAINERS with
two file entries for header files in include/dt-bindings/usb/typec/.

However, these files are not added to the repository with this commit or
any commit in the related patch series. Probably, these file entries are
just needless leftover after the work went through some refactoring.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Remove the two file entries for non-existent header files.

Commit 361104b056 ("dt-bindings: mfd: Convert da9063 to yaml") converts
da9063.txt to dlg,da9063.yaml and adds a new file pattern in MAINTAINERS. 
Unfortunately, the file pattern matches da90*.yaml, but the yaml file is
prefixed with dlg,da90.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken file pattern.

Repair this file pattern in DIALOG SEMICONDUCTOR DRIVERS.

Ji-Ze Hong 88da174369 can: usb: f81604: add Fintek F81604 support
This patch adds support for Fintek USB to 2CAN controller.

Changelog:
v7: https://lore.kernel.org/all/20230509073821.25289-1-peter_hong@fintek.com.tw
  1. Fix consistency of coding style for "break" in f81604_register_urbs().
  2. Remove goto statement in f81604_open().

v6: https://lore.kernel.org/all/20230505022317.22417-1-peter_hong@fintek.com.tw
  1. Remove non-used define and change constant mask to GENMASK().
  2. Move some variables declaration from function start to block start.
  3. Move some variables initization into declaration.
  4. Change variable "id" in f81604_start_xmit() only for CAN ID usage.

v5: https://lore.kernel.org/all/20230420024403.13830-1-peter_hong@fintek.com.tw
  1. Change all u8 *buff to struct f81604_int_data/f81604_can_frame.
  2. Change all netdev->dev_id to netdev->dev_port.
  3. Remove over design for f81604_process_rx_packet(). This device only
     report a frame at once, so the f81604_process_rx_packet() are reduced
     to process 1 frame.

v4: https://lore.kernel.org/all/20230413084253.1524-1-peter_hong@fintek.com.tw
  1. Remove f81604_prepare_urbs/f81604_remove_urbs() and alloc URB/buffer
     dynamically in f81604_register_urbs(), using "urbs_anchor" for manage
     all rx/int URBs.
  2. Add F81604 to MAINTAINERS list.
  3. Change handle_clear_reg_work/handle_clear_overrun_work to single
     clear_reg_work and using bitwise "clear_flags" to record it.
  4. Move __f81604_set_termination in front of f81604_probe() to avoid
     rarely racing condition.
  5. Add __aligned to struct f81604_int_data / f81604_sff / f81604_eff.
  6. Add aligned operations in f81604_start_xmit/f81604_process_rx_packet().
  7. Change lots of CANBUS functions first parameter from struct usb_device*
     to struct f81604_port_priv *priv. But remain f81604_write / f81604_read
     / f81604_update_bits() as struct usb_device* for
     __f81604_set_termination() in probe() stage.
  8. Simplify f81604_read_int_callback() and separate into
     f81604_handle_tx / f81604_handle_can_bus_errors() functions.

v3: https://lore.kernel.org/all/20230327051048.11589-1-peter_hong@fintek.com.tw
  1. Change CAN clock to using MEGA units.
  2. Remove USB set/get retry, only remain SJA1000 reset/operation retry.
  3. Fix all numberic constant to define.
  4. Add terminator control. (only 0 & 120 ohm)
  5. Using struct data to represent INT/TX/RX endpoints data instead byte
     arrays.
  6. Error message reports changed from %d to %pe for mnemotechnic values.
  7. Some bit operations are changed to FIELD_PREP().
  8. Separate TX functions from f81604_read_int_callback().
  9. cf->can_id |= CAN_ERR_CNT in f81604_read_int_callback to report valid
     TX/RX error counts.
  10. Move f81604_prepare_urbs/f81604_remove_urbs() from CAN open/close() to
      USB probe/disconnect().
  11. coding style refactoring.

v2: https://lore.kernel.org/all/20230321081152.26510-1-peter_hong@fintek.com.tw
  1. coding style refactoring.
  2. some const number are defined to describe itself.
  3. fix wrong usage for can_get_echo_skb() in f81604_write_bulk_callback().

Bryan O'Donoghue a4422ff221 usb: typec: qcom: Add Qualcomm PMIC Type-C driver
This commit adds a QCOM PMIC TCPM driver with an initial pm8150b
block.

The driver is layered as follows:

qcom_pmic_typec.c : Responsible for registering with TCPM and arbitrates
                    access to the Type-C and PDPHY hardware blocks in one
                    place.  This presents a single TCPM device to device to
                    the Linux TCPM layer.

qcom_pmic_typec_pdphy.c: Responsible for interfacing with the PDPHY hardware and
                         processing power-delivery related calls from TCPM.
                         This hardware binding can be extended to
                         facilitate similar hardware in different PMICs.

qcom_pmic_typec_port.c: Responsible for notifying and processing Type-C
                        related calls from TCPM. Similar to the pdphy this
                        layer can be extended to handle the specifics of
                        different Qualcomm PMIC Type-C port managers.

This code provides all of the same functionality as the existing
qcom typec driver plus power-delivery as well.

As a result commit 6c8cf36951 ("usb: typec: Add QCOM PMIC typec detection
driver") can be deleted entirely.

References code from Jonathan Marek, Jack Pham, Wesley Cheng, Hemant Kumar,
Guru Das Srinagesh and Ashay Jaiswal.

It seems that we mostly get netdev CCed on wireless patches
which are written by people who don't know any better and
CC everything that get_maintainers spits out. Rather than

Marking them down in patchwork as Awaiting Upstream is

    From schema: Documentation/devicetree/bindings/media/i2c/ovti,ov2685.yaml
 
 2. Maintainers: correct path of Apple PWM binding. This fixes
    refcheckdocs warning.
 
 3. PCI/fsl,imx6q: correct parsing of assigned-clocks and related
    properties and make the clocks more specific per PCI device (host or
    endpoint).  This fixes dtschema limitation and dt_binding_check
    warnings like:
 
    Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.example.dtb: pcie-ep@33800000: Unevaluated properties are not allowed

Linus Torvalds 80e62bc848 MAINTAINERS: re-sort all entries and fields
It's been a few years since we've sorted this thing, and the end result
is that we've added MAINTAINERS entries in the wrong order, and a number
of entries have their fields in non-canonical order too.

So roll this boulder up the hill one more time by re-running

   ./scripts/parse-maintainers.pl --order

on it.

This file ends up being fairly painful for merge conflicts even
normally, since unlike almost all other kernel files it's one of those
"everybody touches the same thing", and re-ordering all entries is only
going to make that worse.  But the alternative is to never do it at all,
and just let it all rot..

The rc2 week is likely the quietest and least painful time to do this.

Add documentation for the WMI subsystem. The documentation describes
both the ACPI WMI interface and the driver API for interacting with
the WMI driver core. The information regarding the ACPI interface
was retrieved from the Ubuntu kernel references and the Windows driver
samples available on GitHub. The documentation is supposed to help
driver developers writing WMI drivers, as many modern machines designed
to run Windows provide an ACPI WMI interface.

Commit 2b6a7409ac ("thermal: intel: menlow: Get rid of this driver")
removes the driver drivers/thermal/intel/intel_menlow.c, but misses to
remove its reference in MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Remove the INTEL MENLOW THERMAL DRIVER section in MAINTAINERS.

Linus Torvalds 348551ddaf Pin control bulk changes for the v6.4 kernel:
Core changes:
 
 - Make a lot of pin controllers with GPIO and irqchips immutable,
   i.e. not living structs, but const structs. This is driving a
   changed initiated by the irqchip maintainers.
 
 New drivers:
 
 - New driver for the NXP S32 SoC pin controller
 
 - As part of a thorough cleanup and restructuring of the
   Ralink/Mediatek drivers, the Ralink MIPS pin control drivers
   were folded into the Mediatek directory and the family is
   renamed "mtmips". The Ralink chips live on as Mediatek MIPS
   family where new variants can be added. As part of this work
   also the device tree bindings were reworked.
 
 - New subdriver for the Qualcomm SM7150 SoC.
 
 - New subdriver for the Qualcomm IPQ9574 SoC.
 
 - New driver for the nVidia BlueField-3 SoC.
 
 - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
 
 - Support for the Qualcomm PMI632 mixed signal circuit GPIO.
 
 Improvements:
 
 - Add some missing pins and generic cleanups on the Renesas
   r8a779g0 and r8a779g0 pin controllers. Generic Renesas
   extension for power source selection on several SoCs.
 
 - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin
   controllers
 
 - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi
   driver.
 
 - Several device tree binding cleanups as the binding
   YAML syntax is solidifying.

Merge tag 'pinctrl-v6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "Mostly drivers! Nothing special: some new Qualcomm chips as usual, and
  the new NXP S32 and nVidia BlueField-3.

  Core changes:

   - Make a lot of pin controllers with GPIO and irqchips immutable,
     i.e. not living structs, but const structs. This is driving a
     changed initiated by the irqchip maintainers.

  New drivers:

   - New driver for the NXP S32 SoC pin controller

   - As part of a thorough cleanup and restructuring of the
     Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were
     folded into the Mediatek directory and the family is renamed
     "mtmips". The Ralink chips live on as Mediatek MIPS family where
     new variants can be added. As part of this work also the device
     tree bindings were reworked.

   - New subdriver for the Qualcomm SM7150 SoC.

   - New subdriver for the Qualcomm IPQ9574 SoC.

   - New driver for the nVidia BlueField-3 SoC.

   - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.

   - Support for the Qualcomm PMI632 mixed signal circuit GPIO.

  Improvements:

   - Add some missing pins and generic cleanups on the Renesas r8a779g0
     and r8a779g0 pin controllers. Generic Renesas extension for power
     source selection on several SoCs.

   - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers

   - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver.

   - Several device tree binding cleanups as the binding YAML syntax is
     solidifying"

Linus Torvalds 310897659c Rust changes for v6.4
More additions to the Rust core. Importantly, this adds the pin-init
 API, which will be used by other abstractions, such as the
 synchronization ones added here too:
 
   - pin-init API: a solution for the safe pinned initialization problem.
     This allows to reduce the need for 'unsafe' code in the kernel when
     dealing with data structures that require a stable address. Commit
     90e53c5e70 ("rust: add pin-init API core") contains a nice
     introduction -- here is an example of how it looks like:
 
         #[pin_data]
         struct Example {
             #[pin]
             value: Mutex<u32>,
 
             #[pin]
             value_changed: CondVar,
         }
 
         impl Example {
             fn new() -> impl PinInit<Self> {
                 pin_init!(Self {
                     value <- new_mutex!(0),
                     value_changed <- new_condvar!(),
                 })
             }
         }
 
         // In a `Box`.
         let b = Box::pin_init(Example::new())?;
 
         // In the stack.
         stack_pin_init!(let s = Example::new());
 
   - 'sync' module: new types 'LockClassKey' ('struct lock_class_key'),
     'Lock', 'Guard', 'Mutex' ('struct mutex'), 'SpinLock'
     ('spinlock_t'), 'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'),
     plus macros such as 'static_lock_class!' and 'new_spinlock!'.
 
     In particular, 'Lock' and 'Guard' are generic implementations that
     contain code that is common to all locks. Then, different backends
     (the new 'Backend' trait) are implemented and used to define types
     like 'Mutex':
 
         type Mutex<T> = Lock<T, MutexBackend>;
 
     In addition, new methods 'assume_init()', 'init_with()' and
     'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()'
     for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display'
     implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of
     'UniqueArc::try_new_uninit()', too.
 
   - 'types' module: new trait 'AlwaysRefCounted' and new type 'ARef'
     (an owned reference to an always-reference-counted object, meant to
     be used in wrappers for C types that have their own ref counting
     functions).
 
     Moreover, new associated functions 'raw_get()' and 'ffi_init()'
     for 'Opaque'.
 
   - New 'task' module with a new type 'Task' ('struct task_struct'), and
     a new macro 'current!' to safely get a reference to the current one.
 
   - New 'ioctl' module with new '_IOC*' const functions (equivalent to
     the C macros).
 
   - New 'uapi' crate, intended to be accessible by drivers directly.
 
   - 'macros' crate: new 'quote!' macro (similar to the one provided in
     userspace by the 'quote' crate); and the 'module!' macro now allows
     specifying multiple module aliases.
 
   - 'error' module: new associated functions for the 'Error' type,
     such as 'from_errno()' and new functions such as 'to_result()'.
 
   - 'alloc' crate: more fallible 'Vec' methods: 'try_resize` and
     'try_extend_from_slice' and the infrastructure (imported from
     the Rust standard library) they need.

 "More additions to the Rust core. Importantly, this adds the pin-init
  API, which will be used by other abstractions, such as the
  synchronization ones added here too:

   - pin-init API: a solution for the safe pinned initialization
     problem.

     This allows to reduce the need for 'unsafe' code in the kernel when
     dealing with data structures that require a stable address. Commit
     90e53c5e70 ("rust: add pin-init API core") contains a nice
     introduction -- here is an example of how it looks like:

        #[pin_data]
        struct Example {
            #[pin]
            value: Mutex<u32>,

            #[pin]
            value_changed: CondVar,
        }

        impl Example {
            fn new() -> impl PinInit<Self> {
                pin_init!(Self {
                    value <- new_mutex!(0),
                    value_changed <- new_condvar!(),
                })
            }
        }

        // In a `Box`.
        let b = Box::pin_init(Example::new())?;

        // In the stack.
        stack_pin_init!(let s = Example::new());

   - 'sync' module:

     New types 'LockClassKey' ('struct lock_class_key'), 'Lock',
     'Guard', 'Mutex' ('struct mutex'), 'SpinLock' ('spinlock_t'),
     'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'), plus macros
     such as 'static_lock_class!' and 'new_spinlock!'.

     In particular, 'Lock' and 'Guard' are generic implementations that
     contain code that is common to all locks. Then, different backends
     (the new 'Backend' trait) are implemented and used to define types
     like 'Mutex':

        type Mutex<T> = Lock<T, MutexBackend>;

     In addition, new methods 'assume_init()', 'init_with()' and
     'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()'
     for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display'
     implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of
     'UniqueArc::try_new_uninit()', too.

   - 'types' module:

     New trait 'AlwaysRefCounted' and new type 'ARef' (an owned
     reference to an always-reference-counted object, meant to be used
     in wrappers for C types that have their own ref counting
     functions).

     Moreover, new associated functions 'raw_get()' and 'ffi_init()' for
     'Opaque'.

   - New 'task' module with a new type 'Task' ('struct task_struct'),
     and a new macro 'current!' to safely get a reference to the current
     one.

   - New 'ioctl' module with new '_IOC*' const functions (equivalent to
     the C macros).

   - New 'uapi' crate, intended to be accessible by drivers directly.

   - 'macros' crate: new 'quote!' macro (similar to the one provided in
     userspace by the 'quote' crate); and the 'module!' macro now allows
     specifying multiple module aliases.

   - 'error' module:

     New associated functions for the 'Error' type, such as
     'from_errno()' and new functions such as 'to_result()'.

   - 'alloc' crate:

     More fallible 'Vec' methods: 'try_resize` and
     'try_extend_from_slice' and the infrastructure (imported from the
     Rust standard library) they need"

Linus Torvalds e81507acdc Nothing looks out of the ordinary in this batch of clk driver updates. There
are a couple patches to the core clk framework, but they're all basically
 cleanups or debugging aids. The driver updates and new additions are dominated
 in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
 new drivers for various SoCs, and MediaTek gained a bunch of drivers for
 MT8188. The MediaTek drivers are being modernized as well, so there are
 updates all over that vendor's clk drivers. There's also a couple other new clk
 drivers in here, for example the Starfive JH7110 SoC support is added.
 
 Outside of the two major SoC vendors though, we have the usual collection of
 non-critical fixes and cleanups to various clk drivers. It's good to see that
 we're getting more cleanups and modernization patches. Maybe one day we'll be
 able to properly split clk providers from clk consumers.
 
 Core:
  - Print an informational message before disabling unused clks
 
 New Drivers:
  - BCM63268 timer clock and reset controller
  - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and

  - Clk driver support for Loongson-2 SoCs
  - Clock driver for Skyworks Si521xx I2C PCIe clock generators
  - Initial Starfive JH7110 clk/reset support
  - Global clock controller drivers for Qualcomm SM7150, IPQ9574, MSM8917 and IPQ5332 SoCs
  - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P SoCs
 
 Updates:
  - Shrink size of clk_fractional_divider a little
  - Convert various clk drivers to devm_of_clk_add_hw_provider()
  - Convert platform clk drivers to remove_new()
  - Converted most Mediatek clock drivers to struct platform_driver
  - MediaTek clock drivers can be built as modules
  - Reimplement Loongson-1 clk driver with DT support
  - Migrate socfpga clk driver to of_clk_add_hw_provider()

Jeremy Kerr 5844564143 i3c: ast2600: Add AST2600 platform-specific driver
Now that we have platform-specific infrastructure for the dw i3c driver,
add platform support for the ASPEED AST2600 SoC.

The AST2600 has a small set of "i3c global" registers, providing
platform-level i3c configuration outside of the i3c core.

For the ast2600, we need a couple of extra setup operations:

 - on probe: find the i3c global register set and parse the SDA pullup
   resistor values

 - on init: set the pullups accordingly, and set the i3c instance IDs

Linus Torvalds b6a7828502 modules-6.4-rc1
The summary of the changes for this pull requests is:
 
  * Song Liu's new struct module_memory replacement
  * Nick Alcock's MODULE_LICENSE() removal for non-modules
  * My cleanups and enhancements to reduce the areas where we vmalloc
    module memory for duplicates, and the respective debug code which
    proves the remaining vmalloc pressure comes from userspace.
 
 Most of the changes have been in linux-next for quite some time except
 the minor fixes I made to check if a module was already loaded
 prior to allocating the final module memory with vmalloc and the
 respective debug code it introduces to help clarify the issue. Although
 the functional change is small it is rather safe as it can only *help*
 reduce vmalloc space for duplicates and is confirmed to fix a bootup
 issue with over 400 CPUs with KASAN enabled. I don't expect stable
 kernels to pick up that fix as the cleanups would have also had to have
 been picked up. Folks on larger CPU systems with modules will want to
 just upgrade if vmalloc space has been an issue on bootup.
 
 Given the size of this request, here's some more elaborate details
 on this pull request.
 
 The functional change change in this pull request is the very first
 patch from Song Liu which replaces the struct module_layout with a new
 struct module memory. The old data structure tried to put together all
 types of supported module memory types in one data structure, the new
 one abstracts the differences in memory types in a module to allow each
 one to provide their own set of details. This paves the way in the
 future so we can deal with them in a cleaner way. If you look at changes
 they also provide a nice cleanup of how we handle these different memory
 areas in a module. This change has been in linux-next since before the
 merge window opened for v6.3 so to provide more than a full kernel cycle
 of testing. It's a good thing as quite a bit of fixes have been found
 for it.
 
 Jason Baron then made dynamic debug a first class citizen module user by
 using module notifier callbacks to allocate / remove module specific
 dynamic debug information.
 
 Nick Alcock has done quite a bit of work cross-tree to remove module
 license tags from things which cannot possibly be module at my request
 so to:
 
   a) help him with his longer term tooling goals which require a
      deterministic evaluation if a piece a symbol code could ever be
      part of a module or not. But quite recently it is has been made
      clear that tooling is not the only one that would benefit.
      Disambiguating symbols also helps efforts such as live patching,
      kprobes and BPF, but for other reasons and R&D on this area
      is active with no clear solution in sight.
 
   b) help us inch closer to the now generally accepted long term goal
      of automating all the MODULE_LICENSE() tags from SPDX license tags
 
 In so far as a) is concerned, although module license tags are a no-op
 for non-modules, tools which would want create a mapping of possible
 modules can only rely on the module license tag after the commit
 8b41fc4454 ("kbuild: create modules.builtin without Makefile.modbuiltin
 or tristate.conf").  Nick has been working on this *for years* and
 AFAICT I was the only one to suggest two alternatives to this approach
 for tooling. The complexity in one of my suggested approaches lies in
 that we'd need a possible-obj-m and a could-be-module which would check
 if the object being built is part of any kconfig build which could ever
 lead to it being part of a module, and if so define a new define
 -DPOSSIBLE_MODULE [0]. A more obvious yet theoretical approach I've
 suggested would be to have a tristate in kconfig imply the same new
 -DPOSSIBLE_MODULE as well but that means getting kconfig symbol names
 mapping to modules always, and I don't think that's the case today. I am
 not aware of Nick or anyone exploring either of these options. Quite
 recently Josh Poimboeuf has pointed out that live patching, kprobes and
 BPF would benefit from resolving some part of the disambiguation as
 well but for other reasons. The function granularity KASLR (fgkaslr)
 patches were mentioned but Joe Lawrence has clarified this effort has
 been dropped with no clear solution in sight [1].
 
 In the meantime removing module license tags from code which could never
 be modules is welcomed for both objectives mentioned above. Some
 developers have also welcomed these changes as it has helped clarify
 when a module was never possible and they forgot to clean this up,
 and so you'll see quite a bit of Nick's patches in other pull
 requests for this merge window. I just picked up the stragglers after
 rc3. LWN has good coverage on the motivation behind this work [2] and
 the typical cross-tree issues he ran into along the way. The only
 concrete blocker issue he ran into was that we should not remove the
 MODULE_LICENSE() tags from files which have no SPDX tags yet, even if
 they can never be modules. Nick ended up giving up on his efforts due
 to having to do this vetting and backlash he ran into from folks who
 really did *not understand* the core of the issue nor were providing
 any alternative / guidance. I've gone through his changes and dropped
 the patches which dropped the module license tags where an SPDX
 license tag was missing, it only consisted of 11 drivers.  To see
 if a pull request deals with a file which lacks SPDX tags you
 can just use:
 
   ./scripts/spdxcheck.py -f \
 	$(git diff --name-only commid-id | xargs echo)
 
 You'll see a core module file in this pull request for the above,
 but that's not related to his changes. WE just need to add the SPDX
 license tag for the kernel/module/kmod.c file in the future but
 it demonstrates the effectiveness of the script.
 
 Most of Nick's changes were spread out through different trees,
 and I just picked up the slack after rc3 for the last kernel was out.
 Those changes have been in linux-next for over two weeks.
 
 The cleanups, debug code I added and final fix I added for modules
 were motivated by David Hildenbrand's report of boot failing on
 a systems with over 400 CPUs when KASAN was enabled due to running
 out of virtual memory space. Although the functional change only
 consists of 3 lines in the patch "module: avoid allocation if module is
 already present and ready", proving that this was the best we can
 do on the modules side took quite a bit of effort and new debug code.
 
 The initial cleanups I did on the modules side of things has been
 in linux-next since around rc3 of the last kernel, the actual final
 fix for and debug code however have only been in linux-next for about a
 week or so but I think it is worth getting that code in for this merge
 window as it does help fix / prove / evaluate the issues reported
 with larger number of CPUs. Userspace is not yet fixed as it is taking
 a bit of time for folks to understand the crux of the issue and find a
 proper resolution. Worst come to worst, I have a kludge-of-concept [3]
 of how to make kernel_read*() calls for modules unique / converge them,
 but I'm currently inclined to just see if userspace can fix this
 instead.

Linus Torvalds cec24b8b6b Char/Misc drivers for 6.4-rc1
Here is the "big" set of char/misc and other driver subsystems for
 6.4-rc1.
 
 It's pretty big, but due to the removal of pcmcia drivers, almost breaks
 even for number of lines added vs. removed, a nice change.
 
 Included in here are:
   - removal of unused PCMCIA drivers (finally!)
   - Interconnect driver updates and additions
   - Lots of IIO driver updates and additions
   - MHI driver updates
   - Coresight driver updates
   - NVMEM driver updates, which required some OF updates
   - W1 driver updates and a new maintainer to manage the subsystem
   - FPGA driver updates
   - New driver subsystem, CDX, for AMD systems
   - lots of other small driver updates and additions
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds 556eb8b791 Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1.
 
 Once again, a busy development cycle, with lots of changes happening in
 the driver core in the quest to be able to move "struct bus" and "struct
 class" into read-only memory, a task now complete with these changes.
 
 This will make the future rust interactions with the driver core more
 "provably correct" as well as providing more obvious lifetime rules for
 all busses and classes in the kernel.
 
 The changes required for this did touch many individual classes and
 busses as many callbacks were changed to take const * parameters
 instead.  All of these changes have been submitted to the various
 subsystem maintainers, giving them plenty of time to review, and most of
 them actually did so.
 
 Other than those changes, included in here are a small set of other
 things:
   - kobject logging improvements
   - cacheinfo improvements and updates
   - obligatory fw_devlink updates and fixes
   - documentation updates
   - device property cleanups and const * changes
   - firwmare loader dependency fixes.
 
 All of these have been in linux-next for a while with no reported

Linus Torvalds fc2e58b8b7 spi: Updates for v6.4
A fairly standard release for SPI with the exception of a change to the
 API for specifying chip selects done in preparation for supporting
 devices with more than one chip select, this required some mechanical
 changes throughout the tree which have been cooking in -next happily for
 a while.  There's also a new API to allow us to TPM chips on half duplex
 controllers.
 
 There's three commits in here that were mangled by a bad interaction
 between the alsa-devel mailing list software and b4, I didn't notice
 until there were merges on top with it being SPI not ALSA.  It seemed
 clear enough to not be worth going back and fixing.
 
  - Refactoring in preparation for supporting multiple chip selects for a
    single device, needed by some flash devices, which required a change
    in the SPI device API visible throughout the tree.
  - Support for hardware assisted interaction with SPI TPMs on half
    duplex controllers, implemented on nVidia Tedra210 QuadSPI.
  - Optimisation for large transfers on fsl-cpm devices.
  - Cleanups around device property use which fix some sisues with
    fwnode.
  - Use of both void remove() and devm_platform_.*ioremap_resource().
  - Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
    Intel MetorLake-S and StarFive J7110 QuadSPI.
 
 The final commit converting to DEV_PM_OPS() was applied late to fix a
 warning that was introduced by some of the earlier work.

Linus Torvalds 1c15ca4e4e sound updates for 6.4-rc1
At this time, it's an interesting mixture of changes for both old and
 new stuff.  Majority of changes are about ASoC (lots of systematic
 changes for converting remove callbacks to void, and cleanups), while
 we got the fixes and the enhancements of very old PCI cards, too.
 
 Here are some highlights:
 
 ALSA/ASoC Core:
 - Continued effort of more ASoC core cleanups
 - Minor improvements for XRUN handling in indirect PCM helpers
 - Code refactoring of PCM core code
 
 ASoC:
 - Continued feature and simplification work on SOF, including addition
   of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4
   protocol
 - Hibernation support for CS35L45
 - More DT binding conversions
 - Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,
   nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas R-Car
   Gen4, Rockchip RK3588 and TI TAS5733
 
 ALSA:
 - Lots of works for legacy emu10k1 and ymfpci PCI drivers
 - PCM kselftest fixes and enhancements

Linus Torvalds 6e98b09da9 Networking changes for 6.4.
Core
 ----
 
  - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
    default value allows for better BIG TCP performances.
 
  - Reduce compound page head access for zero-copy data transfers.
 
  - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
 
  - Threaded NAPI improvements, adding defer skb free support and unneeded
    softirq avoidance.
 
  - Address dst_entry reference count scalability issues, via false
    sharing avoidance and optimize refcount tracking.
 
  - Add lockless accesses annotation to sk_err[_soft].
 
  - Optimize again the skb struct layout.
 
  - Extends the skb drop reasons to make it usable by multiple
    subsystems.
 
  - Better const qualifier awareness for socket casts.
 
 BPF
 ---
 
  - Add skb and XDP typed dynptrs which allow BPF programs for more
    ergonomic and less brittle iteration through data and variable-sized
    accesses.
 
  - Add a new BPF netfilter program type and minimal support to hook
    BPF programs to netfilter hooks such as prerouting or forward.
 
  - Add more precise memory usage reporting for all BPF map types.
 
  - Adds support for using {FOU,GUE} encap with an ipip device operating
    in collect_md mode and add a set of BPF kfuncs for controlling encap
    params.
 
  - Allow BPF programs to detect at load time whether a particular kfunc
    exists or not, and also add support for this in light skeleton.
 
  - Bigger batch of BPF verifier improvements to prepare for upcoming BPF
    open-coded iterators allowing for less restrictive looping capabilities.
 
  - Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
    programs to NULL-check before passing such pointers into kfunc.
 
  - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
    local storage maps.
 
  - Enable RCU semantics for task BPF kptrs and allow referenced kptr
    tasks to be stored in BPF maps.
 
  - Add support for refcounted local kptrs to the verifier for allowing
    shared ownership, useful for adding a node to both the BPF list and
    rbtree.
 
  - Add BPF verifier support for ST instructions in convert_ctx_access()
    which will help new -mcpu=v4 clang flag to start emitting them.
 
  - Add ARM32 USDT support to libbpf.
 
  - Improve bpftool's visual program dump which produces the control
    flow graph in a DOT format by adding C source inline annotations.
 
 Protocols
 ---------
 
  - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
    indicates the provenance of the IP address.
 
  - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
 
  - Add the handshake upcall mechanism, allowing the user-space
    to implement generic TLS handshake on kernel's behalf.
 
  - Bridge: support per-{Port, VLAN} neighbor suppression, increasing
    resilience to nodes failures.
 
  - SCTP: add support for Fair Capacity and Weighted Fair Queueing
    schedulers.
 
  - MPTCP: delay first subflow allocation up to its first usage. This
    will allow for later better LSM interaction.
 
  - xfrm: Remove inner/outer modes from input/output path. These are
    not needed anymore.
 
  - WiFi:
    - reduced neighbor report (RNR) handling for AP mode
    - HW timestamping support
    - support for randomized auth/deauth TA for PASN privacy
    - per-link debugfs for multi-link
    - TC offload support for mac80211 drivers
    - mac80211 mesh fast-xmit and fast-rx support
    - enable Wi-Fi 7 (EHT) mesh support
 
 Netfilter
 ---------
 
  - Add nf_tables 'brouting' support, to force a packet to be routed
    instead of being bridged.
 
  - Update bridge netfilter and ovs conntrack helpers to handle
    IPv6 Jumbo packets properly, i.e. fetch the packet length
    from hop-by-hop extension header. This is needed for BIT TCP
    support.
 
  - The iptables 32bit compat interface isn't compiled in by default
    anymore.
 
  - Move ip(6)tables builtin icmp matches to the udptcp one.
    This has the advantage that icmp/icmpv6 match doesn't load the
    iptables/ip6tables modules anymore when iptables-nft is used.
 
  - Extended netlink error report for netdevice in flowtables and
    netdev/chains. Allow for incrementally add/delete devices to netdev
    basechain. Allow to create netdev chain without device.
 
 Driver API
 ----------
 
  - Remove redundant Device Control Error Reporting Enable, as PCI core
    has already error reporting enabled at enumeration time.
 
  - Move Multicast DB netlink handlers to core, allowing devices other
    then bridge to use them.
 
  - Allow the page_pool to directly recycle the pages from safely
    localized NAPI.
 
  - Implement lockless TX queue stop/wake combo macros, allowing for
    further code de-duplication and sanitization.
 
  - Add YNL support for user headers and struct attrs.
 
  - Add partial YNL specification for devlink.
 
  - Add partial YNL specification for ethtool.
 
  - Add tc-mqprio and tc-taprio support for preemptible traffic classes.
 
  - Add tx push buf len param to ethtool, specifies the maximum number
    of bytes of a transmitted packet a driver can push directly to the
    underlying device.
 
  - Add basic LED support for switch/phy.
 
  - Add NAPI documentation, stop relaying on external links.
 
  - Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
    work to make the hardware timestamping layer selectable by user
    space.
 
  - Add transceiver support and improve the error messages for CAN-FD
    controllers.

Linus Torvalds 0cfcde1faf There are a number of major cleanups in ext4 this cycle:
* The data=journal writepath has been significantly cleaned up and
   simplified, and reduces a large number of data=journal special cases
   by Jan Kara.
 
 * Ojaswin Muhoo has replaced linked list used to track extents that
   have been used for inode preallocation with a red-black tree in the
   multi-block allocator.  This improves performance for workloads
   which do a large number of random allocating writes.
 
 * Thanks to Kemeng Shi for a lot of cleanup and bug fixes in the
   multi-block allocator.
 
 * Matthew wilcox has converted the code paths for reading and writing
   ext4 pages to use folios.
 
 * Jason Yan has continued to factor out ext4_fill_super() into smaller
   functions for improve ease of maintenance and comprehension.
 
 * Josh Triplett has created an uapi header for ext4 userspace API's.

Pull ext4 updates from Ted Ts'o:
 "There are a number of major cleanups in ext4 this cycle:

   - The data=journal writepath has been significantly cleaned up and
     simplified, and reduces a large number of data=journal special
     cases by Jan Kara.

   - Ojaswin Muhoo has replaced linked list used to track extents that
     have been used for inode preallocation with a red-black tree in the
     multi-block allocator. This improves performance for workloads
     which do a large number of random allocating writes.

   - Thanks to Kemeng Shi for a lot of cleanup and bug fixes in the
     multi-block allocator.

   - Matthew wilcox has converted the code paths for reading and writing
     ext4 pages to use folios.

   - Jason Yan has continued to factor out ext4_fill_super() into
     smaller functions for improve ease of maintenance and
     comprehension.

   - Josh Triplett has created an uapi header for ext4 userspace API's"

Merge tag 'gpio-updates-for-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We have some new drivers, significant refactoring of existing intel
  platforms, lots of improvements all around, mass conversion to using
  immutable irqchips by drivers that had not been converted individually
  yet and some changes in the core library code.

  Summary:

  New drivers:
   - add a driver for the Loongson GPIO controller
   - add a driver for the fxl6408 I2C GPIO expander
   - add a GPIO module containing code common for Intel Elkhart Lake and
     Merrifield platforms
   - add a driver for the Intel Elkhart Lake platform reusing the code
     from the intel tangier library

  GPIOLIB core:
   - GPIO ACPI improvements
   - simplify gpiochip_add_data_with_keys() fwnode handling
   - cleanup header inclusions (remove unneeded ones, order the rest
     alphabetically)
   - remove duplicate code (reuse krealloc() instead of open-coding it,
     drop a duplicated check in gpiod_find_and_request())
   - reshuffle the code to remove unnecessary forward declarations
   - coding style cleanups and improvements
   - add a helper for accessing device fwnodes
   - small updates in docs

  Driver improvements:
   - convert all remaining GPIO irqchip drivers to using immutable
     irqchips
   - drop unnecessary of_match_ptr() macro expansions
   - shrink the code in gpio-merrifield significantly by reusing the
     code from gpio-tangier + minor tweaks to the driver code
   - remove MODULE_LICENSE() from drivers that can only be built-in
   - add device-tree support to gpio-loongson1
   - use new regmap features in gpio-104-dio-48e and gpio-pcie-idio-24
   - minor tweaks and fixes to gpio-xra1403, gpio-sim, gpio-tegra194,
     gpio-omap, gpio-aspeed, gpio-raspberrypi-exp
   - shrink code in gpio-ich and gpio-pxa
   - Kconfig tweak for gpio-pmic-eic-sprd"

Linus Torvalds d53c3eaaef ARM: SoC devicetree changes for 6.4
The devicetree changes overall are again dominated by the Qualcomm
 Snapdragon platform that weighs in at over 300 changesets, but there
 are many updates across other platforms as well, notably Mediatek, NXP,
 Rockchips, Renesas, TI, Samsung and ST Microelectronics. These all
 add new features for existing machines, as well as new machines and
 SoCs.
 
 The newly added SoCs are:
 
  - Allwinner T113-s, an Cortex-A7 based variant of the RISC-V
    based D1 chip.
 
  - StarFive JH7110, a RISC-V SoC based on the Sifive U74 core
    like its JH7100 predecessor, but with additional CPU cores
    and a GPU.
 
  - Apple M2 as used in current Macbook Air/Pro and Mac Mini
    gets added, with comparable support as its M1 predecessor.
 
  - Unisoc UMS512 (Tiger T610) is a midrange smartphone SoC
 
  - Qualcomm IPQ5332 and IPQ9574 are Wi-Fi 7 networking SoCs,
    based on the Cortex-A53 and Cortex-A73 cores, respectively.
 
  - Qualcomm sa8775p is an automotive SoC derived from the
    Snapdragon family.
 
 Including the initial board support for the added SoC platforms,
 there are 52 new machines. The largest group are 19 boards
 industrial embedded boards based on the NXP i.MX6 (32-bit)
 and i.MX8 (64-bit) families.
 
 Others include:
 
  - Two boards based on the Allwinner f1c200s ultra-low-cost chip
 
  - Three "Banana Pi" variants based on the Amlogic g12b
    (A311D, S922X) SoC.
 
  - The Gl.Inet mv1000 router based on Marvell Armada 3720
 
  - A Wifi/LTE Dongle based on Qualcomm msm8916
 
  - Two robotics boards based on Qualcomm QRB chips
 
  - Three Snapdragon based phones made by Xiaomi
 
  - Five developments boards based on various Rockchip SoCs,
    including the rk3588s-khadas-edge2 and a few NanoPi
    models
 
  - The AM625 Beagleplay industrial SBC
 
 Another 14 machines get removed: both boards for the obsolete "oxnas"
 platform, three boards for the Renesas r8a77950 SoC that were only for
 pre-production chips, and various chromebook models based on the Qualcomm
 Sc7180 "trogdor" design that were never part of products.

Linus Torvalds e7989789c6 Timers and timekeeping updates:
- Improve the VDSO build time checks to cover all dynamic relocations
 
     VDSO does not allow dynamic relcations, but the build time check is
     incomplete and fragile.
 
     It's based on architectures specifying the relocation types to search
     for and does not handle R_*_NONE relocation entries correctly.
     R_*_NONE relocations are injected by some GNU ld variants if they fail
     to determine the exact .rel[a]/dyn_size to cover trailing zeros.
     R_*_NONE relocations must be ignored by dynamic loaders, so they
     should be ignored in the build time check too.
 
     Remove the architecture specific relocation types to check for and
     validate strictly that no other relocations than R_*_NONE end up
     in the VSDO .so file.
 
   - Prefer signal delivery to the current thread for
     CLOCK_PROCESS_CPUTIME_ID based posix-timers
 
     Such timers prefer to deliver the signal to the main thread of a
     process even if the context in which the timer expires is the current
     task. This has the downside that it might wake up an idle thread.
 
     As there is no requirement or guarantee that the signal has to be
     delivered to the main thread, avoid this by preferring the current
     task if it is part of the thread group which shares sighand.
 
     This not only avoids waking idle threads, it also distributes the
     signal delivery in case of multiple timers firing in the context
     of different threads close to each other better.
 
   - Align the tick period properly (again)
 
     For a long time the tick was starting at CLOCK_MONOTONIC zero, which
     allowed users space applications to either align with the tick or to
     place a periodic computation so that it does not interfere with the
     tick. The alignement of the tick period was more by chance than by
     intention as the tick is set up before a high resolution clocksource is
     installed, i.e. timekeeping is still tick based and the tick period
     advances from there.
 
     The early enablement of sched_clock() broke this alignement as the time
     accumulated by sched_clock() is taken into account when timekeeping is
     initialized. So the base value now(CLOCK_MONOTONIC) is not longer a
     multiple of tick periods, which breaks applications which relied on
     that behaviour.
 
     Cure this by aligning the tick starting point to the next multiple of
     tick periods, i.e 1000ms/CONFIG_HZ.
 
  - A set of NOHZ fixes and enhancements
 
    - Cure the concurrent writer race for idle and IO sleeptime statistics
 
      The statitic values which are exposed via /proc/stat are updated from
      the CPU local idle exit and remotely by cpufreq, but that happens
      without any form of serialization. As a consequence sleeptimes can be
      accounted twice or worse.
 
      Prevent this by restricting the accumulation writeback to the CPU
      local idle exit and let the remote access compute the accumulated
      value.
 
    - Protect idle/iowait sleep time with a sequence count
 
      Reading idle/iowait sleep time, e.g. from /proc/stat, can race with
      idle exit updates. As a consequence the readout may result in random
      and potentially going backwards values.
 
      Protect this by a sequence count, which fixes the idle time
      statistics issue, but cannot fix the iowait time problem because
      iowait time accounting races with remote wake ups decrementing the
      remote runqueues nr_iowait counter. The latter is impossible to fix,
      so the only way to deal with that is to document it properly and to
      remove the assertion in the selftest which triggers occasionally due
      to that.
 
    - Restructure struct tick_sched for better cache layout
 
    - Some small cleanups and a better cache layout for struct tick_sched
 
  - Implement the missing timer_wait_running() callback for POSIX CPU timers
 
    For unknown reason the introduction of the timer_wait_running() callback
    missed to fixup posix CPU timers, which went unnoticed for almost four
    years.
 
    While initially only targeted to prevent livelocks between a timer
    deletion and the timer expiry function on PREEMPT_RT enabled kernels, it
    turned out that fixing this for mainline is not as trivial as just
    implementing a stub similar to the hrtimer/timer callbacks.
 
    The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled systems
    there is a livelock issue independent of RT.
 
    CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU timers
    out from hard interrupt context to task work, which is handled before
    returning to user space or to a VM. The expiry mechanism moves the
    expired timers to a stack local list head with sighand lock held. Once
    sighand is dropped the task can be preempted and a task which wants to
    delete a timer will spin-wait until the expiry task is scheduled back
    in. In the worst case this will end up in a livelock when the preempting
    task and the expiry task are pinned on the same CPU.
 
    The timer wheel has a timer_wait_running() mechanism for RT, which uses
    a per CPU timer-base expiry lock which is held by the expiry code and the
    task waiting for the timer function to complete blocks on that lock.
 
    This does not work in the same way for posix CPU timers as there is no
    timer base and expiry for process wide timers can run on any task
    belonging to that process, but the concept of waiting on an expiry lock
    can be used too in a slightly different way.
 
    Add a per task mutex to struct posix_cputimers_work, let the expiry task
    hold it accross the expiry function and let the deleting task which
    waits for the expiry to complete block on the mutex.
 
    In the non-contended case this results in an extra mutex_lock()/unlock()
    pair on both sides.
 
    This avoids spin-waiting on a task which is scheduled out, prevents the
    livelock and cures the problem for RT and !RT systems.

Pull user work thread updates from Christian Brauner:
 "This contains the work generalizing the ability to create a kernel
  worker from a userspace process.

  Such user workers will run with the same credentials as the userspace
  process they were created from providing stronger security and
  accounting guarantees than the traditional override_creds() approach
  ever could've hoped for.

  The original work was heavily based and optimzed for the needs of
  io_uring which was the first user. However, as it quickly turned out
  the ability to create user workers inherting properties from a
  userspace process is generally useful.

  The vhost subsystem currently creates workers using the kthread api.
  The consequences of using the kthread api are that RLIMITs don't work
  correctly as they are inherited from khtreadd. This leads to bugs
  where more workers are created than would be allowed by the RLIMITs of
  the userspace process in lieu of which workers are created.

  Problems like this disappear with user workers created from the
  userspace processes for which they perform the work. In addition,
  providing this api allows vhost to remove additional complexity. For
  example, cgroup and mm sharing will just work out of the box with user
  workers based on the relevant userspace process instead of manually
  ensuring the correct cgroup and mm contexts are used.

  So the vhost subsystem should simply be made to use the same mechanism
  as io_uring. To this end the original mechanism used for
  create_io_thread() is generalized into user workers:

   - Introduce PF_USER_WORKER as a generic indicator that a given task
     is a user worker, i.e., a kernel task that was created from a
     userspace process. Now a PF_IO_WORKER thread is just a specialized
     version of PF_USER_WORKER. So io_uring io workers raise both flags.

   - Make copy_process() available to core kernel code

   - Extend struct kernel_clone_args with the following bitfields
     allowing to indicate to copy_process():
       - to create a user worker (raise PF_USER_WORKER)
       - to not inherit any files from the userspace process
       - to ignore signals

  After all generic changes are in place the vhost subsystem implements
  a new dedicated vhost api based on user workers. Finally, vhost is
  switched to rely on the new api moving it off of kthreads.

  Thanks to Mike for sticking it out and making it through this rather
  arduous journey"

Merge tag 'rcu.6.4.april5.2023.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jfern/linux

Pull RCU updates from Joel Fernandes:

 - Updates and additions to MAINTAINERS files, with Boqun being added to
   the RCU entry and Zqiang being added as an RCU reviewer.

   I have also transitioned from reviewer to maintainer; however, Paul
   will be taking over sending RCU pull-requests for the next merge
   window.

 - Resolution of hotplug warning in nohz code, achieved by fixing
   cpu_is_hotpluggable() through interaction with the nohz subsystem.

   Tick dependency modifications by Zqiang, focusing on fixing usage of
   the TICK_DEP_BIT_RCU_EXP bitmask.

 - Avoid needless calls to the rcu-lazy shrinker for CONFIG_RCU_LAZY=n
   kernels, fixed by Zqiang.

 - Improvements to rcu-tasks stall reporting by Neeraj.

 - Initial renaming of k[v]free_rcu() to k[v]free_rcu_mightsleep() for
   increased robustness, affecting several components like mac802154,
   drbd, vmw_vmci, tracing, and more.

   A report by Eric Dumazet showed that the API could be unknowingly
   used in an atomic context, so we'd rather make sure they know what
   they're asking for by being explicit:

      https://lore.kernel.org/all/20221202052847.2623997-1-edumazet@google.com/

 - Documentation updates, including corrections to spelling,
   clarifications in comments, and improvements to the srcu_size_state
   comments.

 - Better srcu_struct cache locality for readers, by adjusting the size
   of srcu_struct in support of SRCU usage by Christoph Hellwig.

 - Teach lockdep to detect deadlocks between srcu_read_lock() vs
   synchronize_srcu() contributed by Boqun.

   Previously lockdep could not detect such deadlocks, now it can.

 - Integration of rcutorture and rcu-related tools, targeted for v6.4
   from Boqun's tree, featuring new SRCU deadlock scenarios, test_nmis
   module parameter, and more

 - Miscellaneous changes, various code cleanups and comment improvements

Merge tag 'selinux-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:

 - Stop passing the 'selinux_state' pointers as function arguments

   As discussed during the end of the last development cycle, passing a
   selinux_state pointer through the SELinux code has a noticeable
   impact on performance, and with the current code it is not strictly
   necessary.

   This simplifies things by referring directly to the single
   selinux_state global variable which should help improve SELinux
   performance.

 - Uninline the unlikely portions of avc_has_perm_noaudit()

   This change was also based on a discussion from the last development
   cycle, and is heavily based on an initial proof of concept patch from
   you. The core issue was that avc_has_perm_noaudit() was not able to
   be inlined, as intended, due to its size. We solved this issue by
   extracting the less frequently hit portions of avc_has_perm_noaudit()
   into a separate function, reducing the size of avc_has_perm_noaudit()
   to the point where the compiler began inlining the function. We also
   took the opportunity to clean up some ugly RCU locking in the code
   that became uglier with the change.

 - Remove the runtime disable functionality

   After several years of work by the userspace and distro folks, we are
   finally in a place where we feel comfortable removing the runtime
   disable functionality which we initially deprecated at the start of
   2020.

   There is plenty of information in the kernel's deprecation (now
   removal) notice, but the main motivation was to be able to safely
   mark the LSM hook structures as '__ro_after_init'.

   LWN also wrote a good summary of the deprecation this morning which
   offers a more detailed history:

        https://lwn.net/SubscriberLink/927463/dcfa0d4ed2872f03

 - Remove the checkreqprot functionality

   The original checkreqprot deprecation notice stated that the removal
   would happen no sooner than June 2021, which means this falls hard
   into the "better late than never" bucket.

   The Kconfig and deprecation notice has more detail on this setting,
   but the basic idea is that we want to ensure that the SELinux policy
   allows for the memory protections actually applied by the kernel, and
   not those requested by the process.

   While we haven't found anyone running a supported distro that is
   affected by this deprecation/removal, anyone who is affected would
   only need to update their policy to reflect the reality of their
   applications' mapping protections.

 - Minor Makefile improvements

   Some minor Makefile improvements to correct some dependency issues
   likely only ever seen by SELinux developers. I expect we will have at
   least one more tweak to the Makefile during the next merge window,
   but it didn't quite make the cutoff this time around.

Neeraj Sanjay Kale 689ca16e52 Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets
This adds a driver based on serdev driver for the NXP BT serial protocol
based on running H:4, which can enable the built-in Bluetooth device
inside an NXP BT chip.

This driver has Power Save feature that will put the chip into sleep state
whenever there is no activity for 2000ms, and will be woken up when any
activity is to be initiated over UART.

This driver enables the power save feature by default by sending the vendor
specific commands to the chip during setup.

During setup, the driver checks if a FW is already running on the chip
by waiting for the bootloader signature, and downloads device specific FW
file into the chip over UART if bootloader signature is received..

Takashi Sakamoto f3948874c3 MAINTAINERS: replace maintainer of FireWire subsystem
In the last few years, I have reviewed patches for FireWire subsystem and
requested sound subsystem maintainer to sent them to mainline, since
FireWire subsystem maintainer has been long absent. This situation is not
preferable since we have some user of sound hardware in IEEE 1394 bus.

I will stand for the maintainer, and work for FireWire core functions and
1394 OHCI driver, as well as sound drivers. This commit replaces the
corresponding entry.

As you know, IEEE 1394 is enough legacy. I would like to schedule the end
of my work in the subsystem. My effort will last next 6 years. In 2026, I
will start strong announcement for users to migrate their work load from
IEEE 1394 bus (e.g. by purchasing alternative devices in USB and hardening
system for them), then in 2029 let me resign the maintainer and close
Linux 1394 project.

My current work focuses on real time data (sampling data) transmission
protocol in packet-oriented communication, thus I would provide less help
to implementations for the other type of protocol; i.e. IPv4/IPv6 over
IEEE 1394 bus (firewire-net), SCSI transport protocol over IEEE 1394 bus
(firewire-sbp2) and iSCSI target (sbp-target).

If receiving few objections from developers, I will start my work to send
fixes for v6.3 prepatch, and PR for future v6.4 or later. I'm pleased if
getting any help until the end.

Every time there is some patch/bug, I wish I can get pinged
and I will feedback on that.

For me personally, being a reviewer is an honor and a responsibility,
and it also makes it easier for me to participate in virtio-related
work. And I will spend more time reviewing virtio patch. Better advance
virtio development

I had some contributions to virtio/virtio-net and some support for it.

* per-queue reset
* virtio-net xdp
* some bug fix
* ......

I make a humble request to grant the reviewer role for the virtio core

Miguel Ojeda b0cf5d5021 MAINTAINERS: add Benno Lossin as Rust reviewer
Benno has been involved with the Rust for Linux project for
the better part of a year now. He has been working on solving
the safe pinned initialization problem [1], which resulted in
the pin-init API patch series [2] that allows to reduce the
need for `unsafe` code in the kernel. He is also working on
the field projection RFC for Rust [3] to bring pin-init as
a language feature.

His expertise with the language will be very useful to have
around in the future if Rust grows within the kernel, thus
add him to the `RUST` entry as reviewer.

John Stultz 4daa669efc kernel/configs: Drop Android config fragments
In the old days where each device had a custom kernel, the
android config fragments were useful to provide the required
and reccomended options expected by userland.

However, these days devices are expected to use the GKI kernel,
so these config fragments no longer needed, and out of date, so
they seem to only cause confusion.

So lets drop them. If folks are curious what configs are
expected by the Android environment, check out the gki_defconfig
file in the latest android common kernel tree.
