Pull SoC driver updates from Arnd Bergmann:
"Nothing particular important in the SoC driver updates, just the usual
improvements to for drivers/soc and a couple of subsystems that don't
fit anywhere else:
- The largest set of updates is for Qualcomm SoC drivers, extending
the set of supported features for additional SoCs in the QSEECOM,
LLCC and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip sparx5
and amlogic reset drivers to support additional chips, plus a few
minor updates on other platforms
- The SCMI firmware interface driver gains support for two protocol
extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
and a few bugfixes
- The Hisilicon Kunpeng HCCS driver gains support for configuring
lanes through sysfs
Finally, there are cleanups and minor fixes for drivers/{soc, bus,
memory}, including changing back the .remove_new callback to .remove,
as well as a few other updates for freescale (powerpc) soc drivers,
NXP i.MX soc drivers, cznic turris platform driver, memory controller
drviers, TI OMAP SoC drivers, and Tegra firmware drivers"

Pull SoC devicetree updates from Arnd Bergmann:
"This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device
driver and platform code has already made it in. This is likely the
last ARMv5 (!) platform to ever get added, updating the 20+ year
old at91/sam9 platform with DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number
of A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in
older Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely
related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end
laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and
Tablet chips, still using the older ARMv8.0 cores from
RK3328/RK3399 but with a newer process and other improvements from
the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also
added, these are just lower-cost versions of their normal
counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly
added chips above, notably all the Apple phones and tablets. The other
new machines include nine industrial/embedded boards with NXP i.MX6 or
i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for
Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm
qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.
As usual there are also many newly added features in existing boards
as well as cleanups and minor bugfixes"

Pull asm-generic updates from Arnd Bergmann:
"These are a number of unrelated cleanups, generally simplifying the
architecture specific header files:
- A series from Al Viro simplifies asm/vga.h, after it turns out that
most of it can be generalized.
- A series from Julian Vetter adds a common version of
memcpy_{to,from}io() and memset_io() and changes most architectures
to use that instead of their own implementation
- A series from Niklas Schnelle concludes his work to make PC style
inb()/outb() optional
- Nicolas Pitre contributes improvements for the generic do_div()
helper
- Christoph Hellwig adds a generic version of page_to_phys() and
phys_to_page(), replacing the slightly different architecture
specific definitions.

Pull gpio updates from Bartosz Golaszewski:
"Three new drivers, support for some new models in existing ones and
lots of various tweaks and improvements across the board (switching to
using recommended APIs, code shrink and simplification, etc.).
Also a new feature in the character device uAPI where we now notify
the user-space about changes triggered by in-kernel users as well, not
only when they were done by other user-space agents.
Summary:
GPIOLIB core:
- use the new mem_is_zero() instead of memchr_inv(s, 0, n)
- don't store debounce period twice needlessly
- clean-up debugfs handling
- remove leftover comments referring to no longer used spinlocks
- unduplicate some operations like SRCU locks and initializing GPIO
descriptors
- constify the sysfs class struct
- use lock guards in GPIO sysfs code
- update GPIO uAPI internal flags all at once atomically for
consistency with other places
- modify the behavior of the sysfs interface by no longer exporting
lines that are named inside the driver code or board files with the
sysfs links bearing the line names as this has for many years been
largely unused due to the prevalence of DT, ACPI and firmware nodes
over board files and made the API inconsistent
- for GPIO interrupt providers: free irqs that are still requested by
users when removing the chip
GPIO uAPI:
- notify user-space about changes to GPIO lines' state (requested,
released, reconfigured) triggered from the kernel as well (until
now we'd only do this for changes triggered from user-space)
- to that end: modify the internal workings of the notification
mechanism by switching to an atomic notifier which allows us to
send events from atomic context
- also to that end store the debounce period in the GPIO descriptor
struct and not in the character device context struct
- while at it, also cover the corner-case of users introducing
changes over sysfs while others watch them via the character device
- don't report GPIO lines requested as interrupts as "used" to
user-space as it can still request them as GPIOs
New drivers:
- GPIO part of the MFD Congatec Board Controller
- PolarFire GPIO controller
- GPIOs on FTDI FT2232H
Driver improvements:
- use generic device property accessors instead of OF-specific ones
across many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci,
ts4900, xilinx, mvebu)
- use devres helpers to simplify error paths and either shrink or
entirely remove the driver's remove() callback (grgpio, amdpt,
menz127, max730x, ftgpio010, 74x164, ljca)
- use helper variables to store the address of pdev->dev and avoid
some line-breaks
- use device_for_each_child_node_scoped() to avoid having to put the
fwnode on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
- use a scoped bitmap to simplify the code and drop goto labels in
gpio-aggregator
- drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby,
xilinx)
- add support for new models to gpio-aspeed, gpio-rockchip and
gpio-dwapb
- clean-up ACPI handling and some other bits in gpio-xgene-sb
- replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
- allow to build davinci and mvebu drivers with COMPILE_TEST=y
- remove dead code in gpio-mb86s7x
- switch back to using platform_driver::remove() (after the
conversion to remove_new()) across the GPIO drivers
- remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop
this deprecated symbol
- convert the gpio-altera driver to no longer pull in the deprecated
legacy-of-mm-gpiochip.h header
- use of_property_present() instead of of_property_read_bool() in
gpiolib-of and gpio-rockchip
- allow to build the tegra186 driver on Tegra234 platforms in Kconfig
Late fixes:
- add a missing return value check after devm_kasprintf() to
gpio-grgpio
DT bindings:
- document the ngpios property of gpio-mmio
- add support for a new aspeed model
- fix the example for st,nomadik-gpio
Other:
- kernel doc and comments tweaks
- fix typos in TODO
- reorder headers alphabetically in some drivers
- fix incorrect format specifiers in gpio tools"

Pull pwm updates from Uwe Kleine-König:
"This contains a new abstraction for PWM waveforms that is more
expressive that the legacy one. Compared to the old abstraction it
contains a duty_offset member instead of polarity. This new
abstraction is already used in an ADC driver merged into the iio tree.
The new API requires changes to the lowlevel drivers. For now there
are two drivers that are converted to the new API (axi-pwmgen and
stm32). Converted drivers continue to work with the old API. Drivers
not yet converted only work with the older API.
Otherwise it's the usual collection of fixes, cleanups and dt doc
updates.

Pull ftrace updates from Steven Rostedt:
- Restructure the function graph shadow stack to prepare it for use
with kretprobes
With the goal of merging the shadow stack logic of function graph and
kretprobes, some more restructuring of the function shadow stack is
required.
Move out function graph specific fields from the fgraph
infrastructure and store it on the new stack variables that can pass
data from the entry callback to the exit callback.
Hopefully, with this change, the merge of kretprobes to use fgraph
shadow stacks will be ready by the next merge window.
- Make shadow stack 4k instead of using PAGE_SIZE.
Some architectures have very large PAGE_SIZE values which make its
use for shadow stacks waste a lot of memory.
- Give shadow stacks its own kmem cache.
When function graph is started, every task on the system gets a
shadow stack. In the future, shadow stacks may not be 4K in size.
Have it have its own kmem cache so that whatever size it becomes will
still be efficient in allocations.
- Initialize profiler graph ops as it will be needed for new updates to
fgraph
- Convert to use guard(mutex) for several ftrace and fgraph functions
- Add more comments and documentation
- Show function return address in function graph tracer
Add an option to show the caller of a function at each entry of the
function graph tracer, similar to what the function tracer does.
- Abstract out ftrace_regs from being used directly like pt_regs
ftrace_regs was created to store a partial pt_regs. It holds only the
registers and stack information to get to the function arguments and
return values. On several archs, it is simply a wrapper around
pt_regs. But some users would access ftrace_regs directly to get the
pt_regs which will not work on all archs. Make ftrace_regs an
abstract structure that requires all access to its fields be through
accessor functions.
- Show how long it takes to do function code modifications
When code modification for function hooks happen, it always had the
time recorded in how long it took to do the conversion. But this
value was never exported. Recently the code was touched due to new
ROX modification handling that caused a large slow down in doing the
modifications and had a significant impact on boot times.
Expose the timings in the dyn_ftrace_total_info file. This file was
created a while ago to show information about memory usage and such
to implement dynamic function tracing. It's also an appropriate file
to store the timings of this modification as well. This will make it
easier to see the impact of changes to code modification on boot up
timings.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
- Improve the default select_cpu() implementation making it topology
aware and handle WAKE_SYNC better.
- set_arg_maybe_null() was used to inform the verifier which ops args
could be NULL in a rather hackish way. Use the new __nullable CFI
stub tags instead.
- On Sapphire Rapids multi-socket systems, a BPF scheduler, by
hammering on the same queue across sockets, could live-lock the
system to the point where the system couldn't make reasonable forward
progress.
This could lead to soft-lockup triggered resets or stalling out
bypass mode switch and thus BPF scheduler ejection for tens of
minutes if not hours. After trying a number of mitigations, the
following set worked reliably:
- Injecting artificial cpu_relax() loops in two places while
sched_ext is trying to turn on the bypass mode.
- Triggering scheduler ejection when soft-lockup detection is
imminent (a quarter of threshold left).
While not the prettiest, the impact both in terms of code complexity
and overhead is minimal.
- A common complaint on the API is the overuse of the word "dispatch"
and the confusion around "consume". This is due to how the dispatch
queues became more generic over time. Rename the affected kfuncs for
clarity. Thanks to BPF's compatibility features, this change can be
made in a way that's both forward and backward compatible. The
compatibility code will be dropped in a few releases.

Pull workqueue updates from Tejun Heo:
- The maximum concurrency limit of 512 which was set a long time ago is
too low now.
A legitimate use (BPF cgroup release) of system_wq could saturate it
under stress test conditions leading to false dependencies and
deadlocks.
While the offending use was switched to a dedicated workqueue, use
the opportunity to bump WQ_MAX_ACTIVE four fold and document that
system workqueue shouldn't be saturated. Workqueue should add at
least a warning mechanism for cases where system workqueues are
saturated.
- Recent workqueue updates to support more flexible execution topology

Pull timer updates from Thomas Gleixner:
"A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the
signal of the timer is ignored so that the timer signal can be
delivered once the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small
intervals and keeps the system pointlessly out of low power states
for no value. This is a long standing non-trivial problem due to
the lock order of posix-timer lock and the sighand lock along with
life time issues as the timer and the sigqueue have different life
time rules.
Cure this by:
- Embedding the sigqueue into the timer struct to have the same
life time rules. Aside of that this also avoids the lookup of
the timer in the signal delivery and rearm path as it's just a
always valid container_of() now.
- Queuing ignored timer signals onto a seperate ignored list.
- Moving queued timer signals onto the ignored list when the
signal is switched to SIG_IGN before it could be delivered.
- Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal
delivery code to rearm the timer.
This also required to consolidate the signal delivery rules so they
are consistent across all situations. With that all self test
scenarios finally succeed.
- Core infrastructure for VFS multigrain timestamping
This is required to allow the kernel to use coarse grained time
stamps by default and switch to fine grained time stamps when inode
attributes are actively observed via getattr().
These changes have been provided to the VFS tree as well, so that
the VFS specific infrastructure could be built on top.
- Cleanup and consolidation of the sleep() infrastructure
- Move all sleep and timeout functions into one file
- Rework udelay() and ndelay() into proper documented inline
functions and replace the hardcoded magic numbers by proper
defines.
- Rework the fsleep() implementation to take the reality of the
timer wheel granularity on different HZ values into account.
Right now the boundaries are hard coded time ranges which fail
to provide the requested accuracy on different HZ settings.
- Update documentation for all sleep/timeout related functions
and fix up stale documentation links all over the place
- Fixup a few usage sites
- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP
clocks
A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as
that's the clock which drives the timekeeping adjustments via the
various user space daemons through adjtimex(2).
The non TAI based clock domains are accessible via the file
descriptor based posix clocks, but their usability is very limited.
They can't be accessed fast as they always go all the way out to
the hardware and they cannot be utilized in the kernel itself.
As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.
The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the
kernel provides access to clock MONOTONIC, REALTIME etc.
Instead of creating a duplicated infrastructure this rework
converts timekeeping and adjtimex(2) into generic functionality
which operates on pointers to data structures instead of using
static variables.
This allows to provide time accessors and adjtimex(2) functionality
for the independent PTP clocks in a subsequent step.
- Consolidate hrtimer initialization
hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.
That's an extra unnecessary step and makes Rust support less
straight forward than it should be.
Provide a new set of hrtimer_setup*() functions and convert the
core code and a few usage sites of the less frequently used
interfaces over.
The bulk of the htimer_init() to hrtimer_setup() conversion is
already prepared and scheduled for the next merge window.
- Drivers:
- Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.
Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with
other clusters.
- Mostly boring cleanups, fixes, improvements and code movement"

Pull vdso data page handling updates from Thomas Gleixner:
"First steps of consolidating the VDSO data page handling.
The VDSO data page handling is architecture specific for historical
reasons, but there is no real technical reason to do so.
Aside of that VDSO data has become a dump ground for various
mechanisms and fail to provide a clear separation of the
functionalities.
Clean this up by:
- consolidating the VDSO page data by getting rid of architecture
specific warts especially in x86 and PowerPC.
- removing the last includes of header files which are pulling in
other headers outside of the VDSO namespace.
- seperating timekeeping and other VDSO data accordingly.
Further consolidation of the VDSO page handling is done in subsequent
changes scheduled for the next merge window.
This also lays the ground for expanding the VDSO time getters for
independent PTP clocks in a generic way without making every
architecture add support seperately"

Pull interrupt subsystem updates from Thomas Gleixner:
"Tree wide:
- Make nr_irqs static to the core code and provide accessor functions
to remove existing and prevent future aliasing problems with local
variables or function arguments of the same name.
Core code:
- Prevent freeing an interrupt in the devres code which is not
managed by devres in the first place.
- Use seq_put_decimal_ull_width() for decimal values output in
/proc/interrupts which increases performance significantly as it
avoids parsing the format strings over and over.
- Optimize raising the timer and hrtimer soft interrupts by using the
'set bit only' variants instead of the combined version which
checks whether ksoftirqd should be woken up. The latter is a
pointless exercise as both soft interrupts are raised in the
context of the timer interrupt and therefore never wake up
ksoftirqd.
- Delegate timer/hrtimer soft interrupt processing to a dedicated
thread on RT.
Timer and hrtimer soft interrupts are always processed in ksoftirqd
on RT enabled kernels. This can lead to high latencies when other
soft interrupts are delegated to ksoftirqd as well.
The separate thread allows to run them seperately under a RT
scheduling policy to reduce the latency overhead.
Drivers:
- New drivers or extensions of existing drivers to support Renesas
RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt
chips
- Support for multi-cluster GICs on MIPS.
MIPS CPUs can come with multiple CPU clusters, where each CPU
cluster has its own GIC (Generic Interrupt Controller). This
requires to access the GIC of a remote cluster through a redirect
register block.
This is encapsulated into a set of helper functions to keep the
complexity out of the actual code paths which handle the GIC
details.
- Support for encrypted guests in the ARM GICV3 ITS driver
The ITS page needs to be shared with the hypervisor and therefore
must be decrypted.

Pull debugobjects updates from Thomas Gleixner:
- Prevent destroying the kmem_cache on early failure.
Destroying a kmem_cache requires work queues to be set up, but in the
early failure case they are not yet initializated. So rather leak the
cache instead of triggering a BUG.
- Reduce parallel pool fill attempts.
Refilling the object pool requires to take the global pool lock,
which causes a massive performance issue when a large number of CPUs
attempt to refill concurrently. It turns out that it's sufficient to
let one CPU handle the refill from the to free list and in case there
are not enough objects on it to allocate new objects from the kmem
cache.
This also splits the free list handling from the actual allocation
path as that yields better results on RT where allocation is
restricted to preemptible code paths. The refill from free list has
no such restrictions.
- Consolidate the global and the per CPU pools to use the same data
structure, so all helper functions can be shared.
- Simplify the object allocation/free logic.
The allocation/free logic is an incomprehensible maze, which tries to
utilize the to free list and the global pool in the best way. This
all can be simplified into a straight forward comprehensible code
flow.
- Convert the allocation/free mechanism to batch mode.
Transferring objects from the global pool to the per CPU pools or
vice versa is done by walking the hlist and moving object by object.
That not only increases the pool lock held time, it also dirties up
to 17 cache lines.
This can be avoided by storing the pointer to the first object in a
batch of 16 objects in the objects themself and propagate it through
the batch when an object is enqueued into a pool or to a temporary
hlist head on allocation.
This allows to move batches of objects with at max four cache lines
dirtied and reduces the pool lock held time and therefore contention
significantly.
- Improve the object reusage
The current implementation is too agressively freeing unused objects,
which is counterproductive on bursty workloads like a kernel compile.
Address this by:
* increasing the per CPU pool size
* refilling the per CPU pool from the to be freed pool when the
per CPU pool emptied a batch
* keeping track of object usage with a exponentially wheighted
moving average which prevents the work queue callback to free
objects prematuraly.
This combined reduces the allocation/free rate for a full kernel
compile significantly:
kmem_cache_alloc() kmem_cache_free()
Baseline: 380k 330k
Improved: 170k 117k
- A few cleanups and a more cache line friendly layout of debug
information on top.

Currently if an fopen fails the error exit path is via code that
checks if fp is not null and closes the file, however, fp is null
so this check and close is redundant. Since the only use of the
err exit label is on the fopen check, remove it and replace the
code with a simple return of errno. Also remove variable rc since
it's no longer required.

Pull x86 cpuid updates from Borislav Petkov:
- Add a feature flag which denotes AMD CPUs supporting workload
classification with the purpose of using such hints when making
scheduling decisions
- Determine the boost enumerator for each AMD core based on its type:
efficiency or performance, in the cppc driver
- Add the type of a CPU to the topology CPU descriptor with the goal of
supporting and making decisions based on the type of the respective
core
- Add a feature flag to denote AMD cores which have heterogeneous
topology and enable SD_ASYM_PACKING for those
- Check microcode revisions before disabling PCID on Intel
- Cleanups and fixlets

Pull x86 SEV updates from Borislav Petkov:
- Do the proper memory conversion of guest memory in order to be able
to kexec kernels in SNP guests along with other adjustments and
cleanups to that effect
- Start converting and moving functionality from the sev-guest driver
into core code with the purpose of supporting the secure TSC SNP
feature where the hypervisor cannot influence the TSC exposed to the
guest anymore
- Add a "nosnp" cmdline option in order to be able to disable SNP
support in the hypervisor and thus free-up resources which are not
going to be used
- Cleanups
