ee96dd9614 libnvdimm for 5.18 
- Add perf support for nvdimm events, initially only for 'papr_scm'
   devices.
 
 - Deprecate the 'block aperture' support in libnvdimm, it only ever
   existed in the specification, not in shipping product.

02e2af20f4 Char/Misc and other driver updates for 5.18-rc1 
Here is the big set of char/misc and other small driver subsystem
 updates for 5.18-rc1.
 
 Included in here are merges from driver subsystems which contain:
 	- iio driver updates and new drivers
 	- fsi driver updates
 	- fpga driver updates
 	- habanalabs driver updates and support for new hardware
 	- soundwire driver updates and new drivers
 	- phy driver updates and new drivers
 	- coresight driver updates
 	- icc driver updates
 
 Individual changes include:
 	- mei driver updates
 	- interconnect driver updates
 	- new PECI driver subsystem added
 	- vmci driver updates
 	- lots of tiny misc/char driver updates
 
 There will be two merge conflicts with your tree, one in MAINTAINERS
 which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
 which also should be easy to resolve.
 
 All of these have been in linux-next for a while with no reported
 problems.

710f5d627a USB/Thunderbolt patches for 5.18-rc1 
Here is the big set of USB and Thunderbolt changes for 5.18-rc1.
 
 Nothing major in here, just lots of little improvements and cleanups and
 new device support.  Highlights are:
 	- list iterator fixups for when we walk past the end of the list
 	  (a common problem that was cut/pasted in almost all USB gadget
 	  drivers)
 	- xen USB driver "hardening" for malicious hosts
 	- xhci driver updates and fixes for more hardware types
 	- xhci debug cable fixes to make it actually work again
 	- usb gadget audio driver improvements
 	- usb gadget storage fixes to work with OS-X
 	- lots of other small usb gadget fixes and updates
 	- USB DWC3 driver improvements for more hardware types
 	- Lots of other small USB driver improvements
 	- DTS updates for some USB platforms
 
 Note, the DTS updates will have a merge conflict in your tree.  The
 fixup should be simple, but if not, I can provide a merged tree if
 needed.
 
 All of these have been in linux-next for a while with no reported
 issues.

Pull CXL (Compute Express Link) updates from Dan Williams:
 "This development cycle extends the subsystem to discover CXL resources
  throughout a CXL/PCIe switch topology and respond to hot add/remove
  events anywhere in that topology.

  This is more foundational infrastructure in preparation for dynamic
  memory region provisioning support. Recall that CXL memory regions, as
  the new "Theory of Operation" section of
  Documentation/driver-api/cxl/memory-devices.rst describes, bring
  storage volume striping semantics to memory.

  The hot add/remove behavior is validated with extensions to the
  cxl_test unit test environment and this test in the cxl-cli test
  suite:

Linus Torvalds
169e77764a Networking changes for 5.18. 
Core
 ----
 
  - Introduce XDP multi-buffer support, allowing the use of XDP with
    jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
 
  - Speed up netns dismantling (5x) and lower the memory cost a little.
    Remove unnecessary per-netns sockets. Scope some lists to a netns.
    Cut down RCU syncing. Use batch methods. Allow netdev registration
    to complete out of order.
 
  - Support distinguishing timestamp types (ingress vs egress) and
    maintaining them across packet scrubbing points (e.g. redirect).
 
  - Continue the work of annotating packet drop reasons throughout
    the stack.
 
  - Switch netdev error counters from an atomic to dynamically
    allocated per-CPU counters.
 
  - Rework a few preempt_disable(), local_irq_save() and busy waiting
    sections problematic on PREEMPT_RT.
 
  - Extend the ref_tracker to allow catching use-after-free bugs.
 
 BPF
 ---
 
  - Introduce "packing allocator" for BPF JIT images. JITed code is
    marked read only, and used to be allocated at page granularity.
    Custom allocator allows for more efficient memory use, lower
    iTLB pressure and prevents identity mapping huge pages from
    getting split.
 
  - Make use of BTF type annotations (e.g. __user, __percpu) to enforce
    the correct probe read access method, add appropriate helpers.
 
  - Convert the BPF preload to use light skeleton and drop
    the user-mode-driver dependency.
 
  - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
    its use as a packet generator.
 
  - Allow local storage memory to be allocated with GFP_KERNEL if called
    from a hook allowed to sleep.
 
  - Introduce fprobe (multi kprobe) to speed up mass attachment (arch
    bits to come later).
 
  - Add unstable conntrack lookup helpers for BPF by using the BPF
    kfunc infra.
 
  - Allow cgroup BPF progs to return custom errors to user space.
 
  - Add support for AF_UNIX iterator batching.
 
  - Allow iterator programs to use sleepable helpers.
 
  - Support JIT of add, and, or, xor and xchg atomic ops on arm64.
 
  - Add BTFGen support to bpftool which allows to use CO-RE in kernels
    without BTF info.
 
  - Large number of libbpf API improvements, cleanups and deprecations.
 
 Protocols
 ---------
 
  - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
 
  - Adjust TSO packet sizes based on min_rtt, allowing very low latency
    links (data centers) to always send full-sized TSO super-frames.
 
  - Make IPv6 flow label changes (AKA hash rethink) more configurable,
    via sysctl and setsockopt. Distinguish between server and client
    behavior.
 
  - VxLAN support to "collect metadata" devices to terminate only
    configured VNIs. This is similar to VLAN filtering in the bridge.
 
  - Support inserting IPv6 IOAM information to a fraction of frames.
 
  - Add protocol attribute to IP addresses to allow identifying where
    given address comes from (kernel-generated, DHCP etc.)
 
  - Support setting socket and IPv6 options via cmsg on ping6 sockets.
 
  - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
    Define dscp_t and stop taking ECN bits into account in fib-rules.
 
  - Add support for locked bridge ports (for 802.1X).
 
  - tun: support NAPI for packets received from batched XDP buffs,
    doubling the performance in some scenarios.
 
  - IPv6 extension header handling in Open vSwitch.
 
  - Support IPv6 control message load balancing in bonding, prevent
    neighbor solicitation and advertisement from using the wrong port.
    Support NS/NA monitor selection similar to existing ARP monitor.
 
  - SMC
    - improve performance with TCP_CORK and sendfile()
    - support auto-corking
    - support TCP_NODELAY
 
  - MCTP (Management Component Transport Protocol)
    - add user space tag control interface
    - I2C binding driver (as specified by DMTF DSP0237)
 
  - Multi-BSSID beacon handling in AP mode for WiFi.
 
  - Bluetooth:
    - handle MSFT Monitor Device Event
    - add MGMT Adv Monitor Device Found/Lost events
 
  - Multi-Path TCP:
    - add support for the SO_SNDTIMEO socket option
    - lots of selftest cleanups and improvements
 
  - Increase the max PDU size in CAN ISOTP to 64 kB.
 
 Driver API
 ----------
 
  - Add HW counters for SW netdevs, a mechanism for devices which
    offload packet forwarding to report packet statistics back to
    software interfaces such as tunnels.
 
  - Select the default NIC queue count as a fraction of number of
    physical CPU cores, instead of hard-coding to 8.
 
  - Expose devlink instance locks to drivers. Allow device layer of
    drivers to use that lock directly instead of creating their own
    which always runs into ordering issues in devlink callbacks.
 
  - Add header/data split indication to guide user space enabling
    of TCP zero-copy Rx.
 
  - Allow configuring completion queue event size.
 
  - Refactor page_pool to enable fragmenting after allocation.
 
  - Add allocation and page reuse statistics to page_pool.
 
  - Improve Multiple Spanning Trees support in the bridge to allow
    reuse of topologies across VLANs, saving HW resources in switches.
 
  - DSA (Distributed Switch Architecture):
    - replay and offload of host VLAN entries
    - offload of static and local FDB entries on LAG interfaces
    - FDB isolation and unicast filtering

Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
 "The sprinkling of SPI drivers is because we added a new one and Mark
  sent us a SPI driver interface conversion pull request.

  Core
  ----

   - Introduce XDP multi-buffer support, allowing the use of XDP with
     jumbo frame MTUs and combination with Rx coalescing offloads (LRO).

   - Speed up netns dismantling (5x) and lower the memory cost a little.
     Remove unnecessary per-netns sockets. Scope some lists to a netns.
     Cut down RCU syncing. Use batch methods. Allow netdev registration
     to complete out of order.

   - Support distinguishing timestamp types (ingress vs egress) and
     maintaining them across packet scrubbing points (e.g. redirect).

   - Continue the work of annotating packet drop reasons throughout the
     stack.

   - Switch netdev error counters from an atomic to dynamically
     allocated per-CPU counters.

   - Rework a few preempt_disable(), local_irq_save() and busy waiting
     sections problematic on PREEMPT_RT.

   - Extend the ref_tracker to allow catching use-after-free bugs.

  BPF
  ---

   - Introduce "packing allocator" for BPF JIT images. JITed code is
     marked read only, and used to be allocated at page granularity.
     Custom allocator allows for more efficient memory use, lower iTLB
     pressure and prevents identity mapping huge pages from getting
     split.

   - Make use of BTF type annotations (e.g. __user, __percpu) to enforce
     the correct probe read access method, add appropriate helpers.

   - Convert the BPF preload to use light skeleton and drop the
     user-mode-driver dependency.

   - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
     its use as a packet generator.

   - Allow local storage memory to be allocated with GFP_KERNEL if
     called from a hook allowed to sleep.

   - Introduce fprobe (multi kprobe) to speed up mass attachment (arch
     bits to come later).

   - Add unstable conntrack lookup helpers for BPF by using the BPF
     kfunc infra.

   - Allow cgroup BPF progs to return custom errors to user space.

   - Add support for AF_UNIX iterator batching.

   - Allow iterator programs to use sleepable helpers.

   - Support JIT of add, and, or, xor and xchg atomic ops on arm64.

   - Add BTFGen support to bpftool which allows to use CO-RE in kernels
     without BTF info.

   - Large number of libbpf API improvements, cleanups and deprecations.

  Protocols
  ---------

   - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.

   - Adjust TSO packet sizes based on min_rtt, allowing very low latency
     links (data centers) to always send full-sized TSO super-frames.

   - Make IPv6 flow label changes (AKA hash rethink) more configurable,
     via sysctl and setsockopt. Distinguish between server and client
     behavior.

   - VxLAN support to "collect metadata" devices to terminate only
     configured VNIs. This is similar to VLAN filtering in the bridge.

   - Support inserting IPv6 IOAM information to a fraction of frames.

   - Add protocol attribute to IP addresses to allow identifying where
     given address comes from (kernel-generated, DHCP etc.)

   - Support setting socket and IPv6 options via cmsg on ping6 sockets.

   - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
     Define dscp_t and stop taking ECN bits into account in fib-rules.

   - Add support for locked bridge ports (for 802.1X).

   - tun: support NAPI for packets received from batched XDP buffs,
     doubling the performance in some scenarios.

   - IPv6 extension header handling in Open vSwitch.

   - Support IPv6 control message load balancing in bonding, prevent
     neighbor solicitation and advertisement from using the wrong port.
     Support NS/NA monitor selection similar to existing ARP monitor.

   - SMC
      - improve performance with TCP_CORK and sendfile()
      - support auto-corking
      - support TCP_NODELAY

   - MCTP (Management Component Transport Protocol)
      - add user space tag control interface
      - I2C binding driver (as specified by DMTF DSP0237)

   - Multi-BSSID beacon handling in AP mode for WiFi.

   - Bluetooth:
      - handle MSFT Monitor Device Event
      - add MGMT Adv Monitor Device Found/Lost events

   - Multi-Path TCP:
      - add support for the SO_SNDTIMEO socket option
      - lots of selftest cleanups and improvements

   - Increase the max PDU size in CAN ISOTP to 64 kB.

  Driver API
  ----------

   - Add HW counters for SW netdevs, a mechanism for devices which
     offload packet forwarding to report packet statistics back to
     software interfaces such as tunnels.

   - Select the default NIC queue count as a fraction of number of
     physical CPU cores, instead of hard-coding to 8.

   - Expose devlink instance locks to drivers. Allow device layer of
     drivers to use that lock directly instead of creating their own
     which always runs into ordering issues in devlink callbacks.

   - Add header/data split indication to guide user space enabling of
     TCP zero-copy Rx.

   - Allow configuring completion queue event size.

   - Refactor page_pool to enable fragmenting after allocation.

   - Add allocation and page reuse statistics to page_pool.

   - Improve Multiple Spanning Trees support in the bridge to allow
     reuse of topologies across VLANs, saving HW resources in switches.

   - DSA (Distributed Switch Architecture):
      - replay and offload of host VLAN entries
      - offload of static and local FDB entries on LAG interfaces
      - FDB isolation and unicast filtering

ef510682af f2fs-for-5.18 
In this cycle, f2fs has some performance improvements for Android workloads such
 as using read-unfair rwsems and adding some sysfs entries to control GCs and
 discard commands in more details. In addtiion, it has some tunings to improve
 the recovery speed after sudden power-cut.
 
 Enhancement:
  - add reader-unfair rwsems with F2FS_UNFAIR_RWSEM
   : will replace with generic API support
  - adjust to make the readahead/recovery flow more efficiently
  - sysfs entries to control issue speeds of GCs and Discard commands
  - enable idmapped mounts
 
 Bug fix:
  - correct wrong error handling routines
  - fix missing conditions in quota
  - fix a potential deadlock between writeback and block plug routines
  - fix a deadlock btween freezefs and evict_inode
 
 We've added some boundary checks to avoid kernel panics on corrupted images,
 and several minor code clean-ups.

Pull thermal control updates from Rafael Wysocki:
 "As far as new functionality is concerned, there is a new thermal
  driver for the Intel Hardware Feedback Interface (HFI) along with some
  intel-speed-select utility changes to support it. There are also new
  DT compatible strings for a couple of platforms, and thermal zones on
  some platforms will be registered as HWmon sensors now.

  Apart from the above, some drivers are updated (fixes mostly) and
  there is a new piece of documentation for the Intel DPTF (Dynamic
  Power and Thermal Framework) sysfs interface.

cc6ce5ac2c First set of new device support, fixes, cleanups and features for IIO in 5.18 
This cycle we had quite a few series that applied similar changes
 to lots of drivers. To keep this description manageable I have
 called those out in their own section rather than per driver.
 
 Particularly pleased to see the long running AFE precision series
 going in this cycle.
 
 Series includes some late breaking fixes.
 
 New device support
 * adi,ada4250 amplifier
   - New driver and dt bindings for this programmable gain amplifier.
 * adi,admv1014 microwave down-converter
   - New driver, dt bindings and some device specific ABI that
     may be generalized as more drivers for devices similar to this
     are added.
 * adi,admv4420 K Band down-converter.
   - New driver and dt bindings.
 * adi,adxl367 accelerometer driver.
   - New driver, dt-bindings + some new IIO ABI definitions to support
     reference magnitude events where an estimate of the acceleration
     due to gravity has been removed.
   - A few fixes as follow up patches.
 * adi,ltc2688 DAC with toggle and dither modes.
   - New driver and bindings. Includes some new driver specific (for now)
     ABI for handling toggle mode and the addition of a dither waveform to
     the DAC output.
 * AFE (analog front end) add support for additional types of analog device
   in front of an ADC.
   - RTD temperature sensors with dt bindings.
   - Temperature transducers wit dt bindings.
   - Related cleanup and features listed in other sections below.
 * maxim,ds3502 potentiometer.
   - Add support to ds1803 driver which required significant rework.
 * mediatek,mt2701-auxadc driver
   - Add mediatek,mt8186-auxadc - id table and chip specific info only.
 * semtech,sx9324, semtech,ax9360
   - Substantial refactoring of sx9310 to extract core logic for reuse
     into a separate module
   - New driver using this supporting sx9324 proximity sensors.
   - New driver using this supporting sx9360 proximity sensors.
 * silan,sc7a20
   - Compatible with the st,lis2dh (or nearly anyway) so add ID and
     chip specific info to enable support. Also silan vendor ID added
     for dt-bindings.
 
 Staging graduation
 * adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
   electric cars and similar.
   - Substantial rework of driver required to bring inline with current
     IIO best practice. An unusual device in IIO so some interesting features
     we may see more of in future.
 
 Multiple driver/core cleanup
 - Use sysfs_emit() in simple locations where there is no path to change
   to various core created attributes.
 - Trivial white space fixes around inconsistency between space after { and
   before } in id tables.
 - Introduce new handling for fractional types to avoid repeated similar
   implementations. Use this in 3 drivers. Note this is also targeted
   at future use in the AFE driver and was motivated by discussions
   around the precision related work on that driver.
 - of related header cleanups - drop of*.h and add mod_devicetable.h as
   appropriate.
 - Move a number of symbol exports into IIO_* namespaces.  Two categories,
   1) Library used by multiple drivers e.g. st_sensors
   2) Core driver module exporting functions used by bus specific modules.
   A few related cleanups in this set.
 - Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
   similar to simplify drivers and take advantage of these new macros
   allowing the compiler to do the job or removing unused code without
   the need for __maybe_unused markings. Conversion of other drivers to
   these new macros ongoing.
 
 Features
 * adi,adf4350
   - Switch from of specific to generic device properties enabling use with
     other firmware types.

06384573a3 Documentation: syfs-class-firmware-attributes: Lenovo Certificate support 
Certificate based authentication is available as an alternative to
password based authentication.

The WMI commands are cryptographically signed using a separate
signing server and will be verified by the BIOS before being
accepted.

This commit details the fields that are needed to support that
implementation. At present the changes are intended for Lenovo
platforms, but have been designed to keep them as flexible as possible
for future implementations from other vendors.

3c14b73454 powerpc/pseries: Interface to represent PAPR firmware attributes 
Adds a syscall interface to represent the energy and frequency related
PAPR attributes on the system using the new H_CALL
"H_GET_ENERGY_SCALE_INFO".

H_GET_EM_PARMS H_CALL was previously responsible for exporting this
information in the lparcfg, however the H_GET_EM_PARMS H_CALL
will be deprecated P10 onwards.

The H_GET_ENERGY_SCALE_INFO H_CALL is of the following call format:
hcall(
  uint64 H_GET_ENERGY_SCALE_INFO,  // Get energy scale info
  uint64 flags,           // Per the flag request
  uint64 firstAttributeId,// The attribute id
  uint64 bufferAddress,   // Guest physical address of the output buffer
  uint64 bufferSize       // The size in bytes of the output buffer
);
As specified in PAPR+ v2.11, section 14.14.3.

This H_CALL can query either all the attributes at once with
firstAttributeId = 0, flags = 0 as well as query only one attribute
at a time with firstAttributeId = id, flags = 1.

The output buffer consists of the following
1. number of attributes              - 8 bytes
2. array offset to the data location - 8 bytes
3. version info                      - 1 byte
4. A data array of size num attributes, which contains the following:
  a. attribute ID              - 8 bytes
  b. attribute value in number - 8 bytes
  c. attribute name in string  - 64 bytes
  d. attribute value in string - 64 bytes

The new H_CALL exports information in direct string value format, hence
a new interface has been introduced in
/sys/firmware/papr/energy_scale_info to export this information to
userspace so that the firmware can add new values without the need for
the kernel to be changed.

The H_CALL returns the name, numeric value and string value (if exists)

The format of exposing the sysfs information is as follows:
/sys/firmware/papr/energy_scale_info/
   |-- <id>/
     |-- desc
     |-- value
     |-- value_desc (if exists)
   |-- <id>/
     |-- desc
     |-- value
     |-- value_desc (if exists)
...

The energy information that is exported is useful for userspace tools
such as powerpc-utils. Currently these tools infer the
"power_mode_data" value in the lparcfg, which in turn is obtained from
the to be deprecated H_GET_EM_PARMS H_CALL.

On future platforms, such userspace utilities will have to look at the
data returned from the new H_CALL being populated in this new sysfs
interface and report this information directly without the need of
interpretation.

20f01f1632 blk-crypto: show crypto capabilities in sysfs 
Add sysfs files that expose the inline encryption capabilities of
request queues:

	/sys/block/$disk/queue/crypto/max_dun_bits
	/sys/block/$disk/queue/crypto/modes/$mode
	/sys/block/$disk/queue/crypto/num_keyslots

Userspace can use these new files to decide what encryption settings to
use, or whether to use inline encryption at all.  This also brings the
crypto capabilities in line with the other queue properties, which are
already discoverable via the queue directory in sysfs.

Design notes:

  - Place the new files in a new subdirectory "crypto" to group them
    together and to avoid complicating the main "queue" directory.  This
    also makes it possible to replace "crypto" with a symlink later if
    we ever make the blk_crypto_profiles into real kobjects (see below).

  - It was necessary to define a new kobject that corresponds to the
    crypto subdirectory.  For now, this kobject just contains a pointer
    to the blk_crypto_profile.  Note that multiple queues (and hence
    multiple such kobjects) may refer to the same blk_crypto_profile.

    An alternative design would more closely match the current kernel
    data structures: the blk_crypto_profile could be a kobject itself,
    located directly under the host controller device's kobject, while
    /sys/block/$disk/queue/crypto would be a symlink to it.

    I decided not to do that for now because it would require a lot more
    changes, such as no longer embedding blk_crypto_profile in other
    structures, and also because I'm not sure we can rule out moving the
    crypto capabilities into 'struct queue_limits' in the future.  (Even
    if multiple queues share the same crypto engine, maybe the supported
    data unit sizes could differ due to other queue properties.)  It
    would also still be possible to switch to that design later without
    breaking userspace, by replacing the directory with a symlink.

  - Use "max_dun_bits" instead of "max_dun_bytes".  Currently, the
    kernel internally stores this value in bytes, but that's an
    implementation detail.  It probably makes more sense to talk about
    this value in bits, and choosing bits is more future-proof.

  - "modes" is a sub-subdirectory, since there may be multiple supported
    crypto modes, sysfs is supposed to have one value per file, and it
    makes sense to group all the mode files together.

  - Each mode had to be named.  The crypto API names like "xts(aes)" are
    not appropriate because they don't specify the key size.  Therefore,
    I assigned new names.  The exact names chosen are arbitrary, but
    they happen to match the names used in log messages in fs/crypto/.

  - The "num_keyslots" file is a bit different from the others in that
    it is only useful to know for performance reasons.  However, it's
    included as it can still be useful.  For example, a user might not
    want to use inline encryption if there aren't very many keyslots.

06a4a0cf69 iio: ABI: add note about configuring other attributes during buffer capture 
It might be impossible to configure other attributes (e.g.: events, scale,
sampling rate) if they impact the currently active buffer capture session.

On ADXL367, writing to register before 0x2E requires the device to be
placed in standby mode, otherwise the changes might be effective for
only part of a measurement.

To ensure this requirement, the configuration attributes of the IIO
device try to claim direct mode before switching to standby mode.
During a buffer capture, direct mode cannot be claimed, and the
attribute write callback returns -EBUSY.

Describe this behavior in the buffer/enable attribute description.
