Pull gpio updates from Bartosz Golaszewski:
"The majority of added lines are two new modules: the GPIO virtual
consumer module that improves our ability to add automated tests for
the kernel API and the "sloppy" logic analyzer module that uses the
GPIO API to implement a coarse-grained debugging tool for useful for
remote development.
Other than that we have the usual assortment of various driver
extensions, improvements to the core GPIO code, DT-bindings and other
documentation updates as well as an extension to the interrupt
simulator:
GPIOLIB core:
- rework kfifo handling rework in the character device code
- improve the labeling of GPIOs requested as interrupts and show more
info on interrupt-only GPIOs in debugfs
- remove unused APIs
- unexport interfaces that are only used from the core GPIO code
- drop the return value from gpiochip_set_desc_names() as it cannot
fail
- move a string array definition out of a header and into a specific
compilation unit
- convert the last user of gpiochip_get_desc() other than GPIO core
to using a safer alternative
- use array_index_nospec() where applicable
New drivers:
- add a "virtual GPIO consumer" module that allows requesting GPIOs
from actual hardware and driving tests of the in-kernel GPIO API
from user-space over debugfs
- add a GPIO-based "sloppy" logic analyzer module useful for "first
glance" debugging on remote boards
Driver improvements:
- add support for a new model to gpio-pca953x
- lock GPIOs as interrupts in gpio-sim when the lines are requested
as irqs via the simulator domain + some other minor improvements
- improve error reporting in gpio-syscon
- convert gpio-ath79 to using dynamic GPIO base and range
- use pcibios_err_to_errno() for converting PCIBIOS error codes to
errno vaues in gpio-amd8111 and gpio-rdc321x
- allow building gpio-brcmstb for the BCM2835 architecture
DT bindings:
- convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
- document new properties for aspeed,gpio, fsl,qoriq-gpio and
gpio-vf610
- document new compatibles for pca953x and fsl,qoriq-gpio
Documentation:
- document stricter behavior of the GPIO character device uAPI with
regards to reconfiguring requested line without direction set
- clarify the effect of the active-low flag on line values and edges
- remove documentation for the legacy GPIO API in order to stop
tempting people to use it
- document the preference for using pread() for reading edge events
in the sysfs API
Other:
- add an extended initializer to the interrupt simulator allowing to
specify a number of callbacks callers can use to be notified about
irqs being requested and released"

Pull pwm updates from Uwe Kleine-König:
"This contains the usual mix of fixes, cleanups, two new drivers and
several dt binding updates. The fixes are for minor issues that are
already old (4.11-rc1 and 3.9-rc1) and were found by code review and
not during usage, so I didn't sent them for earlier inclusion.
The changes to include/linux/mfd/stm32-timers.h and
drivers/counter/stm32-timer-cnt.c are part of an immutable branch that
will also be included in the mfd and counter pulls. It changes some
register definitions and affects the pwm-stm32 driver.

Pull power sequencing updates from Bartosz Golaszewski:
"This has been in development since last year's Linux Plumbers
Conference and was inspired by the need to enable support upstream for
Bluetooth/WLAN chips on Qualcomm platforms.
The main problem we're fixing is powering up devices which are
represented as separate objects in the kernel (binding to different
drivers) but which share parts of the power-up sequence and thus need
some kind of a mediator who knows the possible interactions and can
assure they don't interfere with neither device's bring up. An example
of such an inter-driver interaction is the WCN family of BT/WLAN chips
from Qualcomm of which some models require the user to observe a
certain delay between driving the bt-enable and wlan-enable GPIOs.
This is not a new problem but up to this point all attempts at
addressing it ended up hitting one wall or another and being dropped.
The main obstacle was the fact that most these attempts tried to
introduce the concept of a "power sequence" into the device-tree
bindings which breaks the main DT rule: describe the hardware, not its
behavior. The solution I proposed focuses on making the power
sequencer drivers interpret the actual HW description flexibly. More
details on that are in the linked cover letter.
The second problem fixed here is powering up PCI devices before they
are detected on the bus. This is achieved by creating special platform
devices for device-tree nodes describing hard-wired PCI devices which
bind to the so-called PCI power control drivers which enable required
resources and trigger a bus rescan once the controlled device is up
then setup the correct devlink hierarchy for power-management.
By combining the two new frameworks we implemented the power
sequencing PCI power control driver which is capable of powering up
the WLAN modules of the QCom WCN family of chipsets.
All this has spent a significant amount of time in linux-next and
enabled WLAN/BT support on several Qualcomm platforms. To further
prove that this is useful and needed: right after this was picked up
into next, I was sent a series using the subsystem for a similar
use-case on Amlogic platforms.
This contains the core power sequencing framework, the first driver,
PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and
some fixes that came later"

Pull arm64 updates from Catalin Marinas:
"The biggest part is the virtual CPU hotplug that touches ACPI,
irqchip. We also have some GICv3 optimisation for pseudo-NMIs that has
been queued via the arm64 tree. Otherwise the usual perf updates,
kselftest, various small cleanups.
Core:
- Virtual CPU hotplug support for arm64 ACPI systems
- cpufeature infrastructure cleanups and making the FEAT_ECBHB ID
bits visible to guests
- CPU errata: expand the speculative SSBS workaround to more CPUs
- GICv3, use compile-time PMR values: optimise the way regular IRQs
are masked/unmasked when GICv3 pseudo-NMIs are used, removing the
need for a static key in fast paths by using a priority value
chosen dynamically at boot time
ACPI:
- 'acpi=nospcr' option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
Perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs
Kselftest updates:
- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
Miscellaneous:
- arm64 Documentation update with a minor clarification on TBI
- Fix missing IPI statistics
- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)
- Make MTE checking of in-kernel asynchronous tag faults conditional

Pull timer updates from Thomas Gleixner:
"Updates for timers, timekeeping and related functionality:
Core:
- Make the takeover of a hrtimer based broadcast timer reliable
during CPU hot-unplug. The current implementation suffers from a
race which can lead to broadcast timer starvation in the worst
case.
- VDSO related cleanups and simplifications
- Small cleanups and enhancements all over the place
PTP:
- Replace the architecture specific base clock to clocksource, e.g.
ART to TSC, conversion function with generic functionality to avoid
exposing such internals to drivers and convert all existing drivers
over. This also allows to provide functionality which converts the
other way round in the core code based on the same parameter set.

Pull CPU hotplug updates from Thomas Gleixner:
"A small set of SMP/CPU hotplug updates:
- Reverse the order of iteration when freezing secondary CPUs for
hibernation.
This avoids that drivers like the Intel uncore performance counter
have to transfer the assignement of handling the per package uncore
events for every CPU in a package, which is a considerable speedup
on larger systems.
- Add a missing destroy_work_on_stack() invocation in
smp_call_on_cpu() to prevent debug objects to emit a false positive
warning when the stack is freed.

Saeed Mahameed says:
====================
aux-sysfs-irqs
Shay Says:
==========
Introduce auxiliary bus IRQs sysfs
Today, PCI PFs and VFs, which are anchored on the PCI bus, display their
IRQ information in the <pci_device>/msi_irqs/<irq_num> sysfs files. PCI
subfunctions (SFs) are similar to PFs and VFs and these SFs are anchored
on the auxiliary bus. However, these PCI SFs lack such IRQ information
on the auxiliary bus, leaving users without visibility into which IRQs
are used by the SFs. This absence makes it impossible to debug
situations and to understand the source of interrupts/SFs for
performance tuning and debug.
Additionally, the SFs are multifunctional devices supporting RDMA,
network devices, clocks, and more, similar to their peer PCI PFs and
VFs. Therefore, it is desirable to have SFs' IRQ information available
at the bus/device level.
To overcome the above limitations, this short series extends the
auxiliary bus to display IRQ information in sysfs, similar to that of
PFs and VFs.
It adds an 'irqs' directory under the auxiliary device and includes an
<irq_num> sysfs file within it.
For example:
$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/
50 51 52 53 54 55 56 57 58
Patch summary:
patch-1 adds auxiliary bus to support irqs used by auxiliary device
patch-2 mlx5 driver using exposing irqs for PCI SF devices via auxiliary
bus

Pull pidfs updates from Christian Brauner:
"This contains work to make it possible to derive namespace file
descriptors from pidfd file descriptors.
Right now it is already possible to use a pidfd with setns() to
atomically change multiple namespaces at the same time. In other
words, it is possible to switch to the namespace context of a process
using a pidfd. There is no need to first open namespace file
descriptors via procfs.
The work included here is an extension of these abilities by allowing
to open namespace file descriptors using a pidfd. This means it is now
possible to interact with namespaces without ever touching procfs.
To this end a new set of ioctls() on pidfds is introduced covering all
supported namespace types"

Pull vfs mount query updates from Christian Brauner:
"This contains work to extend the abilities of listmount() and
statmount() and various fixes and cleanups.
Features:
- Allow iterating through mounts via listmount() from newest to
oldest. This makes it possible for mount(8) to keep iterating the
mount table in reverse order so it gets newest mounts first.
- Relax permissions on listmount() and statmount().
It's not necessary to have capabilities in the initial namespace:
it is sufficient to have capabilities in the owning namespace of
the mount namespace we're located in to list unreachable mounts in
that namespace.
- Extend both listmount() and statmount() to list and stat mounts in
foreign mount namespaces.
Currently the only way to iterate over mount entries in mount
namespaces that aren't in the caller's mount namespace is by
crawling through /proc in order to find /proc/<pid>/mountinfo for
the relevant mount namespace.
This is both very clumsy and hugely inefficient. So extend struct
mnt_id_req with a new member that allows to specify the mount
namespace id of the mount namespace we want to look at.
Luckily internally we already have most of the infrastructure for
this so we just need to expose it to userspace. Give userspace a
way to retrieve the id of a mount namespace via statmount() and
through a new nsfs ioctl() on mount namespace file descriptor.
This comes with appropriate selftests.
- Expose mount options through statmount().
Currently if userspace wants to get mount options for a mount and
with statmount(), they still have to open /proc/<pid>/mountinfo to
parse mount options. Simply the information through statmount()
directly.
Afterwards it's possible to only rely on statmount() and
listmount() to retrieve all and more information than
/proc/<pid>/mountinfo provides.
This comes with appropriate selftests.
Fixes:
- Avoid copying to userspace under the namespace semaphore in
listmount.
Cleanups:
- Simplify the error handling in listmount by relying on our newly
added cleanup infrastructure.
- Refuse invalid mount ids early for both listmount and statmount"

Pull vfs inode / dentry updates from Christian Brauner:
"This contains smaller performance improvements to inodes and dentries:
inode:
- Add rcu based inode lookup variants.
They avoid one inode hash lock acquire in the common case thereby
significantly reducing contention. We already support RCU-based
operations but didn't take advantage of them during inode
insertion.
Callers of iget_locked() get the improvement without any code
changes. Callers that need a custom callback can switch to
iget5_locked_rcu() as e.g., did btrfs.
With 20 threads each walking a dedicated 1000 dirs * 1000 files
directory tree to stat(2) on a 32 core + 24GB ram vm:
before: 3.54s user 892.30s system 1966% cpu 45.549 total
after: 3.28s user 738.66s system 1955% cpu 37.932 total (-16.7%)
Long-term we should pick up the effort to introduce more
fine-grained locking and possibly improve on the currently used
hash implementation.
- Start zeroing i_state in inode_init_always() instead of doing it in
individual filesystems.
This allows us to remove an unneeded lock acquire in new_inode()
and not burden individual filesystems with this.
dcache:
- Move d_lockref out of the area used by RCU lookup to avoid
cacheline ping poing because the embedded name is sharing a
cacheline with d_lockref.
- Fix dentry size on 32bit with CONFIG_SMP=y so it does actually end
up with 128 bytes in total"

In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.
Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

Change the API to select MAC default time stamping instead of the PHY.
Indeed the PHY is closer to the wire therefore theoretically it has less
delay than the MAC timestamping but the reality is different. Due to lower
time stamping clock frequency, latency in the MDIO bus and no PHC hardware
synchronization between different PHY, the PHY PTP is often less precise
than the MAC. The exception is for PHY designed specially for PTP case but
these devices are not very widespread. For not breaking the compatibility
default_timestamp flag has been introduced in phy_device that is set by
the phy driver to know we are using the old API behavior.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for for v6.11
There are a lot of changes in here, though the big bulk of things is
cleanups and simplifications of various kinds which are internally
rather than externally visible. A good chunk of those are DT schema
conversions, but there's also a lot of changes in the code.
Highlights:
- Syncing of features between simple-audio-card and the two
audio-graph cards so there is no reason to stick with an older
driver.
- Support for specifying the order of operations for components within
cards to allow quirking for unusual systems.
- New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5
and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments PCM5242.

Timestamping software or hardware flags are often used as a group,
therefore adding these masks will ease future use.
I did not use SOF_TIMESTAMPING_SYS_HARDWARE flag as it is deprecated and
not used at all.

Initial implementation of the power sequencing subsystem for linux v6.11
|
|
The 'dsa_tag_8021q_bridge_join' could be used as a generic implementation
of the 'ds->ops->port_bridge_join()' function. However, it is necessary
to synchronize their arguments.
This patch also moves the 'tx_fwd_offload' flag configuration line into
'dsa_tag_8021q_bridge_join' body. Currently, every (sja1105) driver sets
it, and the future vsc73xx implementation will also need it for
simplification.

There were several undocumented fields in structs irq_domain_ops and
irq_domain_info. Document them.
irq_domain_ops::revmap_size contained "[]" in the description, which is not
allowed in sphinx. Remove that.
Finally, plug the whole header (irqdomain.h) into genericirq.rst, so that
the docs is autogenerated and hyperlinks to these structure are created.

The callers of request_irq() don't care about IRQF_ONESHOT because they
don't provide threaded handlers, but if they happen to share the IRQ with
the ACPI SCI, which has a threaded handler and sets IRQF_ONESHOT,
request_irq() will fail for them due to a flags mismatch.
Address this by making request_irq() add IRQF_COND_ONESHOT to the flags
passed to request_threaded_irq() for all of its callers.

vmovp_lock is abused in a number of cases to serialise updates
to vlpi_count[] and deal with map/unmap of a VM to ITSs.
Instead, provide a per-VM lock and revisit the use of vlpi_count[]
so that it is always wrapped in this per-VM vmapp_lock.
This reduces the potential contention on a concurrent VMOVP command,
and paves the way for subsequent VPE locking that holding vmovp_lock
actively prevents due to the lock ordering.

commit 21c690a349ba ("mm: introduce slabobj_ext to support slab object

MEMCG to SLAB_OBJ_EXT. This action make memcg_data exposed while !MEMCG.
As Vlastimil Babka suggested, let's add _unused_slab_obj_exts for
SLAB_MATCH for slab.obj_exts while !MEMCG. That could resolve the match
issue, clean up the feature logical.

Add a new helper to disable lockdep tracking entirely for a given class.
This is needed for bcachefs, which takes too many btree node locks for
lockdep to track. Instead, we have a single lockdep_map for "btree_trans
has any btree nodes locked", which makes more since given that we have
centralized lock management and a cycle detector.

The codgen for adding architecture-specific stack alignment to the
effective alloca() usage is somewhat inefficient and allows a bit to get
carried beyond the desired entropy range. This isn't really a problem,
but it's unexpected and the codegen is kind of bad.
Quoting Mark[1], the disassembly for arm64's invoke_syscall() looks like:
// offset = raw_cpu_read(kstack_offset)
mov x4, sp
adrp x0, kstack_offset
mrs x5, tpidr_el1
add x0, x0, #:lo12:kstack_offset
ldr w0, [x0, x5]
// offset = KSTACK_OFFSET_MAX(offset)
and x0, x0, #0x3ff
// alloca(offset)
add x0, x0, #0xf
and x0, x0, #0x7f0
sub sp, x4, x0
... which in C would be:
offset = raw_cpu_read(kstack_offset)
offset &= 0x3ff; // [0x0, 0x3ff]
offset += 0xf; // [0xf, 0x40e]
offset &= 0x7f0; // [0x0,
... so when *all* bits [3:0] are 0, they'll have no impact, and when
*any* of bits [3:0] are 1 they'll trigger a carry into bit 4, which
could ripple all the way up and spill into bit 10.
Switch the masking in KSTACK_OFFSET_MAX() to explicitly clear the bottom
bits to avoid the rounding by using 0b1111110000 instead of 0b1111111111:
// offset = raw_cpu_read(kstack_offset)
mov x4, sp
adrp x0, 0 <kstack_offset>
mrs x5, tpidr_el1
add x0, x0, #:lo12:kstack_offset
ldr w0, [x0, x5]
// offset = KSTACK_OFFSET_MAX(offset)
and x0, x0, #0x3f0
// alloca(offset)
sub sp, x4, x0

When argmin was added in commit 655c16a8ce9c ("exec: separate
MM_ANONPAGES and RLIMIT_STACK accounting"), it was intended only for
validating stack limits on CONFIG_MMU[1]. All checking for reaching the
limit (argmin) is wrapped in CONFIG_MMU ifdef checks, though setting
argmin was not. That argmin is only supposed to be used under CONFIG_MMU
was rediscovered recently[2], and I don't want to trip over this again.
Move argmin's declaration into the existing CONFIG_MMU area, and add
helpers functions so the MMU tests can be consolidated.

Expose a new cap sf_eq_usage. The vhca_resource_manager can write this
cap, indicating the SF driver should use max_num_eqs_24b to determine
how many EQs to use.
Will be used in the next patch, to indicate to the SF driver from the PF
that the user has set the max io eqs via devlink. So the SF driver can
later query the proper max eq value from the new cap.
