babe393974 The number of commits for documentation is not huge this time around, but 
there are some significant changes nonetheless:
 
 - Some more Spanish-language and Chinese translations.
 
 - The much-discussed documentation of the confidential-computing threat
   model.
 
 - Powerpc and RISCV documentation move under Documentation/arch - these
   complete this particular bit of documentation churn.
 
 - A large traditional-Chinese documentation update.
 
 - A new document on backporting and conflict resolution.
 
 - Some kernel-doc and Sphinx fixes.
 
 Plus the usual smattering of smaller updates and typo fixes.

1e0c505e13 asm-generic updates for v6.7 
The ia64 architecture gets its well-earned retirement as planned,
 now that there is one last (mostly) working release that will
 be maintained as an LTS kernel.
 
 The architecture specific system call tables are updated for
 the added map_shadow_stack() syscall and to remove references
 to the long-gone sys_lookup_dcookie() syscall.

db74e16258 crypto: qat - add rate limiting sysfs interface 
Add an interface for the rate limiting feature which allows to add,
remove and modify a QAT SLA (Service Level Agreement).

This adds a new sysfs attribute group, `qat_rl`, which can be accessed
from /sys/bus/pci/devices/<BUS:DEV:FUNCTION> with the following
hierarchy:
    |-+ qat_rl
      |---- id  (RW) # SLA identifier
      |---- cir (RW) # Committed Information Rate
      |---- pir (RW) # Peak Information Rate
      |---- srv (RW) # Service to be rate limited
      |---- rp  (RW) (HEX) # Ring pairs to be rate limited
      |---- cap_rem  (RW)  # Remaining capability for a service
      |---- sla_op   (WO)  # Allows to perform an operation on an SLA

The API works by setting the appropriate RW attributes and then
issuing a command through the `sla_op`. For example, to create an SLA, a
user needs to input the necessary data into the attributes cir, pir, srv
and rp and then write into `sla_op` the command `add` to execute the
operation.
The API also provides `cap_rem` attribute to get information about
the remaining device capability within a certain service which is
required when setting an SLA.

e079231676 crypto: qat - add pm_status debugfs file 
QAT devices implement a mechanism that allows them to go autonomously
to a low power state depending on the load.

Expose power management info by providing the "pm_status" file under
debugfs. This includes PM state, PM event log, PM event counters, PM HW
CSRs, per-resource type constrain counters and per-domain power gating
status specific to the QAT device.

This information is retrieved from (1) the FW by means of
ICP_QAT_FW_PM_INFO command, (2) CSRs and (3) counters collected by the
device driver.

318d97849f platform/x86: think-lmi: Add bulk save feature 
On Lenovo platforms there is a limitation in the number of times an
attribute can be saved. This is an architectural limitation and it limits
the number of attributes that can be modified to 48.
A solution for this is instead of the attribute being saved after every
modification allow a user to bulk set the attributes and then trigger a
final save. This allows unlimited attributes.

This patch introduces a save_settings attribute that can be configured to
either single or bulk mode by the user.
Single mode is the default but customers who want to avoid the 48
attribute limit can enable bulk mode.

Displaying the save_settings attribute will display the enabled mode.

When in bulk mode writing 'save' to the save_settings attribute will
trigger a save. Once this has been done a reboot is required before more
attributes can be modified.

37b14f2dfa crypto: qat - enable dc chaining service 
QAT GEN4 devices support chained compression operations. These
allow, with a single request to firmware, to hash then compress
data.

Extend the configuration to enable such mode. The cfg_services
operations in sysfs are extended to allow the string "dcc". When
selected, the driver downloads to the device both the symmetric
crypto and the compression firmware images and sends an admin message
to firmware which enables `chained` operations.
In addition, it sets the device's capabilities as the combination
of compression and symmetric crypto capabilities, while excluding
the ICP_ACCEL_CAPABILITIES_CRYPTO_SYMMETRIC bit to indicate
that in this mode, symmetric crypto instances are not supported.

When "dcc" is enabled, the device will handle compression requests
as if the "dc" configuration is loaded ("dcc" is a variation of "dc")
and the driver will register the acomp algorithms.

As for the other extended configurations, "dcc" is only available for
qat_4xxx devices and the chaining service will be only accessible from
user space.

In this cycle, we don't have a highlighted feature enhancement, but mostly
 have fixed issues mainly in two parts: 1) zoned block device, 2) compression
 support. For zoned block device, we've tried to improve the power-off recovery
 flow as much as possible. For compression, we found some corner cases caused by
 wrong compression policy and logics. Other than them, there were some reverts
 and stat corrections.
 
 Bug fix:
  - use finish zone command when closing a zone
  - check zone type before sending async reset zone command
  - fix to assign compress_level for lz4 correctly
  - fix error path of f2fs_submit_page_read()
  - don't {,de}compress non-full cluster
  - send small discard commands during checkpoint back
  - flush inode if atomic file is aborted
  - correct to account gc/cp stats
 
 And, there are minor bug fixes, avoiding false lockdep warning, and clean-ups.

1544df9ab4 ARM: SoC drivers for 6.6 
The main change this time is the introduction of the drivers/genpd
 subsystem that gets split out from drivers/soc to keep common
 functionality together. Ulf Hansson is taking over maintainership for
 these and is sending a separate pull request with the same commits,
 but they are in the soc drivers tree to avoid conflicts against other
 soc driver patches.
 
 The SCMI driver subsystem gets an update to version 3.2 of the
 specification. There are also updates to memory, reset and other firmware
 drivers.
 
 On the soc driver side, the updates are mostly cleanups across a number
 of Arm platforms. On driver for loongarch adds power management for DT
 based systems, another driver is for HiSilicon's Arm server chips with
 their HCCS system health interface.
 
 The remaining updates for the most part add support for additional
 hardware in existing drivers or contain minor cleanups. Most of these
 are for the Qualcomm Snapdragon platform.

   itself without needing to recompile the kernel, update the IMA
   architecture specific policy rules to require the IMA policy itself
   be signed.

   [ As commit 099f26f22f was upstreamed in linux-6.4, updating the
     IMA architecture specific policy now to require signed IMA policies
     may break userspace expectations. ]

 - IMA only checked the file data hash was not on the system blacklist
   keyring for files with an appended signature (e.g. kernel modules,
   Power kernel image).

   Check all file data hashes regardless of how it was signed

 - Code cleanup, and a kernel-doc update

6f49693a6c Updates for the CPU hotplug core: 
- Support partial SMT enablement.
 
     So far the sysfs SMT control only allows to toggle between SMT on and
     off. That's sufficient for x86 which usually has at max two threads
     except for the Xeon PHI platform which has four threads per core.
 
     Though PowerPC has up to 16 threads per core and so far it's only
     possible to control the number of enabled threads per core via a
     command line option. There is some way to control this at runtime, but
     that lacks enforcement and the usability is awkward.
 
     This update expands the sysfs interface and the core infrastructure to
     accept numerical values so PowerPC can build SMT runtime control for
     partial SMT enablement on top.
 
     The core support has also been provided to the PowerPC maintainers who
     added the PowerPC related changes on top.
 
   - Minor cleanups and documentation updates.

88a6f89944 crash: memory and CPU hotplug sysfs attributes 
Introduce the crash_hotplug attribute for memory and CPUs for use by
userspace.  These attributes directly facilitate the udev rule for
managing userspace re-loading of the crash kernel upon hot un/plug
changes.

For memory, expose the crash_hotplug attribute to the
/sys/devices/system/memory directory.  For example:

 # udevadm info --attribute-walk /sys/devices/system/memory/memory81
  looking at device '/devices/system/memory/memory81':
    KERNEL=="memory81"
    SUBSYSTEM=="memory"
    DRIVER==""
    ATTR{online}=="1"
    ATTR{phys_device}=="0"
    ATTR{phys_index}=="00000051"
    ATTR{removable}=="1"
    ATTR{state}=="online"
    ATTR{valid_zones}=="Movable"

  looking at parent device '/devices/system/memory':
    KERNELS=="memory"
    SUBSYSTEMS==""
    DRIVERS==""
    ATTRS{auto_online_blocks}=="offline"
    ATTRS{block_size_bytes}=="8000000"
    ATTRS{crash_hotplug}=="1"

For CPUs, expose the crash_hotplug attribute to the
/sys/devices/system/cpu directory. For example:

 # udevadm info --attribute-walk /sys/devices/system/cpu/cpu0
  looking at device '/devices/system/cpu/cpu0':
    KERNEL=="cpu0"
    SUBSYSTEM=="cpu"
    DRIVER=="processor"
    ATTR{crash_notes}=="277c38600"
    ATTR{crash_notes_size}=="368"
    ATTR{online}=="1"

  looking at parent device '/devices/system/cpu':
    KERNELS=="cpu"
    SUBSYSTEMS==""
    DRIVERS==""
    ATTRS{crash_hotplug}=="1"
    ATTRS{isolated}==""
    ATTRS{kernel_max}=="8191"
    ATTRS{nohz_full}=="  (null)"
    ATTRS{offline}=="4-7"
    ATTRS{online}=="0-3"
    ATTRS{possible}=="0-7"
    ATTRS{present}=="0-3"

With these sysfs attributes in place, it is possible to efficiently
instruct the udev rule to skip crash kernel reloading for kernels
configured with crash hotplug support.

For example, the following is the proposed udev rule change for RHEL
system 98-kexec.rules (as the first lines of the rule file):

 # The kernel updates the crash elfcorehdr for CPU and memory changes
 SUBSYSTEM=="cpu", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end"
 SUBSYSTEM=="memory", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end"

When examined in the context of 98-kexec.rules, the above rules test if
crash_hotplug is set, and if so, the userspace initiated
unload-then-reload of the crash kernel is skipped.

CPU and memory checks are separated in accordance with CONFIG_HOTPLUG_CPU
and CONFIG_MEMORY_HOTPLUG kernel config options.  If an architecture
supports, for example, memory hotplug but not CPU hotplug, then the
/sys/devices/system/memory/crash_hotplug attribute file is present, but
the /sys/devices/system/cpu/crash_hotplug attribute file will NOT be
present.  Thus the udev rule skips userspace processing of memory hot
un/plug events, but the udev rule will evaluate false for CPU events, thus
allowing userspace to process CPU hot un/plug events (ie the
unload-then-reload of the kdump capture kernel).

7e38a7422f mlxbf-bootctl: Support sysfs entries for MFG fields 
This patch extends the mlxbf-bootctl driver's sysfs entries
to support read and write access for the manufacturing (MFG)
fields in the board-level EEPROM.  The MFG fields are set
once during the board manufacturing phase, and then the MFG
fields are write-protected.

44f0fb8dfe leds: trigger: netdev: rename 'hw_control' sysfs entry to 'offloaded' 
Commit b655892ffd ("leds: trigger: netdev: expose hw_control status
via sysfs") exposed to sysfs the flag that tells whether the LED trigger
is offloaded to hardware, under the name "hw_control", since that is the
name under which this setting is called in the code.

Everywhere else in kernel when some work that is normally done in
software can be made to be done by hardware instead, we use the word
"offloading" to describe this, e.g. "LED blinking is offloaded to
hardware".

Normally renaming sysfs entries is a no-go because of backwards
compatibility. But since this patch was not yet released in a stable
kernel, I think it is still possible to rename it, if there is
consensus.
