Pull gpio updates from Bartosz Golaszewski:
"The biggest feature is the locking overhaul. Up until now the
synchronization in the GPIO subsystem was broken. There was a single
spinlock "protecting" multiple data structures but doing it wrong (as
evidenced by several places where it would be released when a sleeping
function was called and then reacquired without checking the protected
state).
We tried to use an RW semaphore before but the main issue with GPIO is
that we have drivers implementing the interfaces in both sleeping and
non-sleeping ways as well as user-facing interfaces that can be called
both from process as well as atomic contexts. Both ends converge in
the same code paths that can use neither spinlocks nor mutexes. The
only reasonable way out is to use SRCU and go mostly lockless. To that
end: we add several SRCU structs in relevant places and use them to
assure consistency between API calls together with atomic reads and
writes of GPIO descriptor flags where it makes sense.
This code has spent several weeks in next and has received several
fixes in the first week or two after which it stabilized nicely. The
GPIO subsystem is now resilient to providers being suddenly unbound.
We managed to also remove the existing character device RW semaphore
and the obsolete global spinlock.
Other than the locking rework we have one new driver (for Chromebook
EC), much appreciated documentation improvements from Kent and the
regular driver improvements, DT-bindings updates and GPIOLIB core
tweaks.
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to
GPIO device structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being
unbound while the API calls are in progress
- don't dereference the SRCU-protected chip pointer if the
information we need can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to
struct gpio_device to further reduce the need to dereference the
former
- pass the GPIO device struct instead of the GPIO chip to sysfs
callback to, again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for
the same reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations
- remove the global GPIO spinlock
- remove the character device RW semaphore
Core GPIOLIB:
- constify pointers in GPIO API where applicable
- unify the GPIO counting APIs for ACPI and OF
- provide a macro for iterating over all GPIOs, not only the ones
that are requested
- remove leftover typedefs
- pass the consumer device to GPIO core in
devm_fwnode_gpiod_get_index() for improved logging
- constify the GPIO bus type
- don't warn about removing GPIO chips with descriptors still held by
users as we can now handle this situation gracefully
- remove unused logging helpers
- unexport functions that are only used internally in the GPIO
subsystem
- set the device type (assign the relevant struct device_type) for
GPIO devices
New drivers:
- add the ChromeOS EC GPIO driver
Driver improvements:
- allow building gpio-vf610 with COMPILE_TEST as well as disabling it
in menuconfig (before it was always built for i.MX cofigs)
- count the number of EICs using the device properties instead of
hard-coding it in gpio-eic-sprd
- improve the device naming, extend the debugfs output and add
lockdep asserts to gpio-sim
DT bindings:
- document the 'label' property for gpio-pca9570
- convert aspeed,ast2400-gpio bindings to DT schema
- disallow unevaluated properties for gpio-mvebu
- document a new model in renesas,rcar-gpio
Documentation:
- improve the character device kerneldocs in user-space headers
- add proper documentation for the character device uAPI (both v1 and v2)
- move the sysfs and gpio-mockup docs into the "obsolete" section
- improve naming consistency for GPIO terms
- clarify the line values description for sysfs
- minor docs improvements
- improve the driver API contract for setting GPIO direction
- mark unsafe APIs as deprecated in kerneldocs and suggest
replacements
Other:
- remove an obsolete test from selftests"

Pull device mapper VDO target from Mike Snitzer:
"Introduce the DM vdo target which provides block-level deduplication,
compression, and thin provisioning. Please see:
Documentation/admin-guide/device-mapper/vdo.rst
Documentation/admin-guide/device-mapper/vdo-design.rst
The DM vdo target handles its concurrency by pinning an IO, and
subsequent stages of handling that IO, to a particular VDO thread.
This aspect of VDO is "unique" but its overall implementation is very
tightly coupled to its mostly lockless threading model. As such, VDO
is not easily changed to use more traditional finer-grained locking
and Linux workqueues. Please see the "Zones and Threading" section of
vdo-design.rst
The DM vdo target has been used in production for many years but has
seen significant changes over the past ~6 years to prepare it for
upstream inclusion. The codebase is still large but it is isolated to
drivers/md/dm-vdo/ and has been made considerably more approachable
and maintainable.
Matt Sakai has been added to the MAINTAINERS file to reflect that he
will send VDO changes upstream through the DM subsystem maintainers"

Move CXL protocol error types from einj.c (now einj-core.c) to einj-cxl.c.
einj-cxl.c implements the necessary handling for CXL protocol error
injection and exposes an API for the CXL core to use said functionality,
while also allowing the EINJ module to be built without CXL support.
Because CXL error types targeting CXL 1.0/1.1 ports require special
handling, only allow them to be injected through the new cxl debugfs
interface (next commit) and return an error when attempting to inject
through the legacy interface.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code:
- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).
- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).
Netfilter:
- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.
- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.
BPF:
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.
Wireless:
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API:
- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from
drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc:
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".

Pull EDAC updates from Borislav Petkov:
- Add a FRU (Field Replaceable Unit) memory poison manager which
collects and manages previously encountered hw errors in order to
save them to persistent storage across reboots. Previously recorded
errors are "replayed" upon reboot in order to poison memory which has
caused said errors in the past.
The main use case is stacked, on-chip memory which cannot simply be
replaced so poisoning faulty areas of it and thus making them
inaccessible is the only strategy to prolong its lifetime.
- Add an AMD address translation library glue which converts the
reported addresses of hw errors into system physical addresses in
order to be used by other subsystems like memory failure, for
example. Add support for MI300 accelerators to that library.

Pull x86 FRED support from Thomas Gleixner:
"Support for x86 Fast Return and Event Delivery (FRED).
FRED is a replacement for IDT event delivery on x86 and addresses most
of the technical nightmares which IDT exposes:
1) Exception cause registers like CR2 need to be manually preserved
in nested exception scenarios.
2) Hardware interrupt stack switching is suboptimal for nested
exceptions as the interrupt stack mechanism rewinds the stack on
each entry which requires a massive effort in the low level entry
of #NMI code to handle this.
3) No hardware distinction between entry from kernel or from user
which makes establishing kernel context more complex than it needs
to be especially for unconditionally nestable exceptions like NMI.
4) NMI nesting caused by IRET unconditionally reenabling NMIs, which
is a problem when the perf NMI takes a fault when collecting a
stack trace.
5) Partial restore of ESP when returning to a 16-bit segment
6) Limitation of the vector space which can cause vector exhaustion
on large systems.
7) Inability to differentiate NMI sources
FRED addresses these shortcomings by:
1) An extended exception stack frame which the CPU uses to save
exception cause registers. This ensures that the meta information
for each exception is preserved on stack and avoids the extra
complexity of preserving it in software.
2) Hardware interrupt stack switching is non-rewinding if a nested
exception uses the currently interrupt stack.
3) The entry points for kernel and user context are separate and GS
BASE handling which is required to establish kernel context for
per CPU variable access is done in hardware.
4) NMIs are now nesting protected. They are only reenabled on the
return from NMI.
5) FRED guarantees full restore of ESP
6) FRED does not put a limitation on the vector space by design
because it uses a central entry points for kernel and user space
and the CPUstores the entry type (exception, trap, interrupt,
syscall) on the entry stack along with the vector number. The
entry code has to demultiplex this information, but this removes
the vector space restriction.
The first hardware implementations will still have the current
restricted vector space because lifting this limitation requires
further changes to the local APIC.
7) FRED stores the vector number and meta information on stack which
allows having more than one NMI vector in future hardware when the
required local APIC changes are in place.
The series implements the initial FRED support by:
- Reworking the existing entry and IDT handling infrastructure to
accomodate for the alternative entry mechanism.
- Expanding the stack frame to accomodate for the extra 16 bytes FRED
requires to store context and meta information
- Providing FRED specific C entry points for events which have
information pushed to the extended stack frame, e.g. #PF and #DB.
- Providing FRED specific C entry points for #NMI and #MCE
- Implementing the FRED specific ASM entry points and the C code to
demultiplex the events
- Providing detection and initialization mechanisms and the necessary
tweaks in context switching, GS BASE handling etc.
The FRED integration aims for maximum code reuse vs the existing IDT
implementation to the extent possible and the deviation in hot paths
like context switching are handled with alternatives to minimalize the
impact. The low level entry and exit paths are seperate due to the
extended stack frame and the hardware based GS BASE swichting and
therefore have no impact on IDT based systems.
It has been extensively tested on existing systems and on the FRED
simulation and as of now there are no outstanding problems"

Pull timer updates from Thomas Gleixner:
"A large set of updates and features for timers and timekeeping:
- The hierarchical timer pull model
When timer wheel timers are armed they are placed into the timer
wheel of a CPU which is likely to be busy at the time of expiry.
This is done to avoid wakeups on potentially idle CPUs.
This is wrong in several aspects:
1) The heuristics to select the target CPU are wrong by
definition as the chance to get the prediction right is
close to zero.
2) Due to #1 it is possible that timers are accumulated on
a single target CPU
3) The required computation in the enqueue path is just overhead
for dubious value especially under the consideration that the
vast majority of timer wheel timers are either canceled or
rearmed before they expire.
The timer pull model avoids the above by removing the target
computation on enqueue and queueing timers always on the CPU on
which they get armed.
This is achieved by having separate wheels for CPU pinned timers
and global timers which do not care about where they expire.
As long as a CPU is busy it handles both the pinned and the global
timers which are queued on the CPU local timer wheels.
When a CPU goes idle it evaluates its own timer wheels:
- If the first expiring timer is a pinned timer, then the global
timers can be ignored as the CPU will wake up before they
expire.
- If the first expiring timer is a global timer, then the expiry
time is propagated into the timer pull hierarchy and the CPU
makes sure to wake up for the first pinned timer.
The timer pull hierarchy organizes CPUs in groups of eight at the
lowest level and at the next levels groups of eight groups up to
the point where no further aggregation of groups is required, i.e.
the number of levels is log8(NR_CPUS). The magic number of eight
has been established by experimention, but can be adjusted if
needed.
In each group one busy CPU acts as the migrator. It's only one CPU
to avoid lock contention on remote timer wheels.
The migrator CPU checks in its own timer wheel handling whether
there are other CPUs in the group which have gone idle and have
global timers to expire. If there are global timers to expire, the
migrator locks the remote CPU timer wheel and handles the expiry.
Depending on the group level in the hierarchy this handling can
require to walk the hierarchy downwards to the CPU level.
Special care is taken when the last CPU goes idle. At this point
the CPU is the systemwide migrator at the top of the hierarchy and
it therefore cannot delegate to the hierarchy. It needs to arm its
own timer device to expire either at the first expiring timer in
the hierarchy or at the first CPU local timer, which ever expires
first.
This completely removes the overhead from the enqueue path, which
is e.g. for networking a true hotpath and trades it for a slightly
more complex idle path.
This has been in development for a couple of years and the final
series has been extensively tested by various teams from silicon
vendors and ran through extensive CI.
There have been slight performance improvements observed on network
centric workloads and an Intel team confirmed that this allows them
to power down a die completely on a mult-die socket for the first
time in a mostly idle scenario.
There is only one outstanding ~1.5% regression on a specific
overloaded netperf test which is currently investigated, but the
rest is either positive or neutral performance wise and positive on
the power management side.
- Fixes for the timekeeping interpolation code for cross-timestamps:
cross-timestamps are used for PTP to get snapshots from hardware
timers and interpolated them back to clock MONOTONIC. The changes
address a few corner cases in the interpolation code which got the
math and logic wrong.
- Simplifcation of the clocksource watchdog retry logic to
automatically adjust to handle larger systems correctly instead of
having more incomprehensible command line parameters.
- Treewide consolidation of the VDSO data structures.
- The usual small improvements and cleanups all over the place"

Pull ntfs update from Christian Brauner:
"This removes the old ntfs driver. The new ntfs3 driver is a full
replacement that was merged over two years ago. We've went through
various userspace and either they use ntfs3 or they use the fuse
version of ntfs and thus build neither ntfs nor ntfs3. I think that's
a clear sign that we should risk removing the legacy ntfs driver.
Quoting from Arch Linux and Debian:
- Debian does neither build the legacy ntfs nor the new ntfs3:
"Not currently built with Debian's kernel packages, 'ntfs' has been
symlinked to 'ntfs-3g' as it relates to fstab and mount commands.
Debian kernels are built without support of the ntfs3 driver
developed by Paragon Software." (cf. [2])
- Archlinux provides ntfs3 as their default since 5.15:
"All officially supported kernels with versions 5.15 or newer are
built with CONFIG_NTFS3_FS=m and thus support it. Before 5.15,

Pull kselftest update from Shuah Khan:
- livepatch restructuring to move the module out of lib to be built as
a out-of-tree modules during kselftest build. This makes it easier
change, debug and rebuild the tests by running make on the
selftests/livepatch directory, which is not currently possible since
the modules on lib/livepatch are build and installed using the main
makefile modules target.
- livepatch restructuring fixes for problems found by kernel test
robot. The change skips the test if kernel-devel isn't installed
(default value of KDIR), or if KDIR variable passed doesn't exists.
- resctrl test restructuring and new non-contiguous CBMs CAT test
- new ktap_helpers to print diagnostic messages, pass/fail tests based
on exit code, abort test, and finish the test.
- a new test verify power supply properties.
- a new ftrace to exercise function tracer across cpu hotplug.
- timeout increase for mqueue test to allow the test to run on i3.metal
AWS instances.
- minor spelling corrections in several tests.
- missing gitignore files and changes to existing gitignore files.

cleanups and minor enhancements but hardly anything on the core and only
one new driver. Highlights include:
- SoundWire support for AMD ACP 6.3 systems.
- Support for reporting version information for AVS firmware.
- Support DSPless mode for Intel Soundwire systems.
- Support for configuring CS35L56 amplifiers using EFI calibration
data.

The ExpressWire protocol is shared between at least KTD2692 and KTD2801
with slight differences such as timings and the former not having a
defined set of pulses for enabling the protocol (possibly because it
does not support PWM unlike KTD2801). Despite these differences the
ExpressWire handling code can be shared between the two, so in
preparation for adding KTD2801 support introduce a library implementing
this protocol.

Reset controller updates for v6.9

add a GPIO-based reset controller criver for shared GPIO resets, extract
an of_phandle_args_equal() helper function out of cpufreq, and use it in

Samsung SoC driver changes for v6.9, part two
1. Extend Exynos PMU (Power Management Unit) driver being also the
syscon to main system controller registers block, to support Google
GS101. The Google GS101 has PMU registers protected and writing is
available only via SMC. The Exynos PMU will register its own custom
regmap for such case of mixed MMIO+SMC.
2. Rework Samsung watchdog driver to get the regmap to PMU block not
via syscon API, but from the Exynos PMU driver. This is necessary
for the watchdog driver to work on Google GS101.

Arm SCMI updates for v6.9
Quite a few changes to extend support to SCMI v3.2 specification,
to enhance notification handling and other miscellaneous updates.
1. Enhancements to notification handling
Until now, trying to register a notifier for an unsuppported
notification returned an error genrating unneeded message exchanges
with the SCMI platform. This can be avoided by looking up in advance
the specific protocol and resources available.
With these changes SCMI driver user will fail to register a notifier
if the related command or resource is not supported (like before)
without the need of exchanging any message.
Perf notifications are also extended to provide the pre-calculated
frequencies corresponding to the level or index carried by the
2. More SCMI v3.2 related updates
One of the main addition includes a centralized support to the SCMI
core to handle v3.2 optional protocol version negotiation, so that
at protocol initialization time, if the platform advertised version
is newer than supported by the kernel and protocol version negotiation
is supported, the SCMI core will attempt to negotiate an older protocol
version.
It also includes the clock get permissions which indicates if any of
the clock operations are forbidden by the platform for the OSPM agent.
It can be used in the clock driver to avoid unnecessary message
exchanges between the kernel and the platform which will always end
up with the failure. It also includes other missing bits of clock
v3.2 protocol so that the supported protocol version can be bumped
to 0x30000 (v3.2).
3. Miscellaneous updates
This includes addition of warning if the domain frequency multiplier
is 0 or rounded off to indicate the actual frequencies are either
wrong ot rounded off, hardening of clock domain info lookups, addition
of multiple protocols registration support within a SCMI driver,
update to SCMI entry in MAINTAINERS to include HWMON driver and
constifying the scmi_bus_type structure.
This also includes couple for fixes to minor issues: double free in
SMC transport cleanup path and struct kernel-doc warnings in optee
transport.

Commit f34158edd249 ("MAINTAINERS: Add entry for Mobileye MIPS SoCs") adds
the section MOBILEYE MIPS SOCS with a file entry to the non-existing file
include/dt-bindings/soc/mobileye,eyeq5.h.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.
Possibly, this file was part of an early patch series, but in the final
patch series, this file does not appear anymore.
Delete this file entry in the MOBILEYE MIPS SOCS section.

Add a second document on bisecting regressions explaining the whole
process from beginning to end -- while also describing how to validate
if a problem is still present in mainline. This "two in one" approach
is possible, as checking whenever a bug is in mainline is one of the
first steps before performing a bisection anyway and thus needs to be
described. Due to this approach the text also works quite nicely in
conjunction with Documentation/admin-guide/reporting-issues.rst, as it
covers all typical cases where users will need to build a kernel in
exactly the same order.
The text targets users that normally run kernels from their Linux
distributor who might never have compiled their own kernel.
This aim is why the first kernel built while following this guide is
generated from the latest mainline codebase. This will rule out that the
regression (a) was fixed already and (b) is caused by config change a
vendor distributor performed; checking mainline will furthermore (c)
determine if the issue is something that needs to be reported to the
regular developers or the stable team (this is needed even when readers
bisect within a stable series).
Only then are readers instructed to build their own variant of the
'good' kernel to validate the trimmed .config file created during early
in the guide, as performing a bisection with a broken one would be a
waste of time. There is a small downside of this order: readers might
have to go back to testing mainline, if it turns out there is a problem
with their .config. But that should be rare -- and if the regression was
already fixed readers might not get to this point anyway. Hence in the
end this order should mean that readers built less kernels overall.
This sequence allows the text to easily cover the "check if a bug is
present in the upstream kernel" case while only making things a tiny bit
more complicated.
The text tries to prevent readers from running into many mistakes users
are known to frequently make. The steps required for this might look
superfluous for people that are already familiar with bisections -- but
anyone with that knowledge should be able to adapt the instructions to
their use-case or will not need this text at all.
Style and structure of the text match the one
Documentation/admin-guide/quickly-build-trimmed-linux.rst uses. Quite a
few paragraphs are even copied from there and not changed at all or only
slightly. This will complicate maintenance, as some future changes to
one of these documents will have to be replicated in the other. But this
is the lesser evil: solutions like "sending readers from one document
over to the other" or "extracting the common parts into a separate
document" might work in other cases, but would be too confusing here
given the topic and the target audience.
