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.
This time around thanks go to Andy Shevchenko, Clark Wang, Conor
Dooley, David Lechner, Dimitri Fedrau, Frank Li, Jun Li, Kelvin Zhang,
Krzysztof Kozlowski, Nuno Sa, Shen Lichuan and Trevor Gamblin for code

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.

The minimal alignment of an integral type may differ from its size,
hence is not safe to assume that an arbitrary freeptr_t (which is
basically an unsigned long) is always aligned to 4 or 8 bytes.
As nothing seems to require the additional alignment, it is safe to fix
this by relaxing the check to the actual minimum alignment of freeptr_t.

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
made unbound workqueues use per-cpu worker pool frontends which
pushed up workqueue flush overhead.
As consecutive CPUs are likely to be pointing to the same worker
pool, reduce overhead by switching locks only when necessary.

Add a check to the ovl_dentry_weird() function to prevent the
processing of directory inodes that lack the lookup function.
This is important because such inodes can cause errors in overlayfs
when passed to the lowerstack.

Currently the mount_setattr_test fails on machines with a 64K PAGE_SIZE,
with errors such as:
# RUN mount_setattr_idmapped.invalid_fd_negative ...
mkfs.ext4: No space left on device while writing out and closing file system
# mount_setattr_test.c:1055:invalid_fd_negative:Expected system("mkfs.ext4 -q /mnt/C/ext4.img") (256) == 0 (0)
# invalid_fd_negative: Test terminated by assertion
# FAIL mount_setattr_idmapped.invalid_fd_negative
not ok 12 mount_setattr_idmapped.invalid_fd_negative
The code creates a 100,000 byte tmpfs:
ASSERT_EQ(mount("testing", "/mnt", "tmpfs", MS_NOATIME | MS_NODEV,
"size=100000,mode=700"), 0);
And then a little later creates a 2MB ext4 filesystem in that tmpfs:
ASSERT_EQ(ftruncate(img_fd, 1024 * 2048), 0);
ASSERT_EQ(system("mkfs.ext4 -q /mnt/C/ext4.img"), 0);
At first glance it seems like that should never work, after all 2MB is
larger than 100,000 bytes. However the filesystem image doesn't actually
occupy 2MB on "disk" (actually RAM, due to tmpfs). On 4K kernels the
ext4.img uses ~84KB of actual space (according to du), which just fits.
However on 64K PAGE_SIZE kernels the ext4.img takes at least 256KB,
which is too large to fit in the tmpfs, hence the errors.
It seems fraught to rely on the ext4.img taking less space on disk than
the allocated size, so instead create the tmpfs with a size of 2MB. With
that all 21 tests pass on 64K PAGE_SIZE kernels.
