Description for this pull request:
- Fix a remount failure caused by differing process masks by inheriting
the original mount options during the remount process.
- Fix a potential divide-by-zero error and system crash in
exfat_allocate_bitmap that occurred when the readahead count was zero.
- Add validation for directory cluster bitmap bits to prevent directory
and root cluster from being incorrectly zeroed out on corrupted images.
- Clear the post-EOF page cache when extending a file to prevent stale
mmap data from becoming visible, addressing an generic/363 failure.
- Fix a reference count leak in exfat_find by properly releasing
the dentry set in specific error paths.

Some filesystems use a kinda-sorta controlled dentry refcount leak to pin
dentries of created objects in dcache (and undo it when removing those).
Reference is grabbed and not released, but it's not actually _stored_
anywhere. That works, but it's hard to follow and verify; among other
things, we have no way to tell _which_ of the increments is intended
to be an unpaired one. Worse, on removal we need to decide whether
the reference had already been dropped, which can be non-trivial if
that removal is on umount and we need to figure out if this dentry is
pinned due to e.g. unlink() not done. Usually that is handled by using
kill_litter_super() as ->kill_sb(), but there are open-coded special
cases of the same (consider e.g. /proc/self).
Things get simpler if we introduce a new dentry flag (DCACHE_PERSISTENT)
marking those "leaked" dentries. Having it set claims responsibility
for +1 in refcount.
The end result this series is aiming for:
* get these unbalanced dget() and dput() replaced with new primitives that
would, in addition to adjusting refcount, set and clear persistency flag.
* instead of having kill_litter_super() mess with removing the remaining
"leaked" references (e.g. for all tmpfs files that hadn't been removed
prior to umount), have the regular shrink_dcache_for_umount() strip
DCACHE_PERSISTENT of all dentries, dropping the corresponding
reference if it had been set. After that kill_litter_super() becomes
an equivalent of kill_anon_super().
Doing that in a single step is not feasible - it would affect too many places
in too many filesystems. It has to be split into a series.
This work has really started early in 2024; quite a few preliminary pieces
have already gone into mainline. This chunk is finally getting to the
meat of that stuff - infrastructure and most of the conversions to it.
Some pieces are still sitting in the local branches, but the bulk of
that stuff is here.

Summary
* Move jiffies converters out of kernel/sysctl.c Moved the jiffies converters into kernel/time/jiffies.c and replaced the pipe-max-size proc_handler converter with a macro based version. This is all part of the effort to relocate non-sysctl logic out of kernel/sysctl.c into more relevant subsystems. No functional changes. * Generalize proc handler converter creation Removed duplicated sysctl converter logic by consolidating it in macros.

ftrace fixes for v6.19:
- Fix regression of pid filtering of function graph tracer When the function graph tracer allowed multiple instances of graph tracing using subops, the filtering by pid broke. The ftrace_ops->private that was used for pid filtering wasn't updated on creation. The wrong function entry callback was used when pid filtering was enabled when the function graph tracer started, which meant that the pid filtering wasn't happening. - Remove no longer needed ftrace_trace_task() With PID filtering working via ftrace_pids_enabled() and fgraph_pid_func(), the coarse-grained ftrace_trace_task() check in graph_entry() is obsolete. It was only a fallback for uninitialized op->private (now fixed), and its removal ensures consistent PID filtering with standard function tracing. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaS90FhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrqMAQDbU53VhvZ6rE0pNvu0Tlk+LDCu3gxg F2wisWr65389OgD/VFLTVRjCZh1iY7FFWjAPGRCMbetljmMgK5vpH6XSigA= =VKaD -----END PGP SIGNATURE----- Merge tag 'ftrace-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Fix regression of pid filtering of function graph tracer When the function graph tracer allowed multiple instances of graph tracing using subops, the filtering by pid broke.

tracing updates for v6.19:
- Merge branch shared with kprobes on extending trace options
The trace options were defined by a 32 bit variable. This limits the
tracing instances to have a total of 32 different options. As that limit
has been hit, and more options are being added, increase the option mask
to a 64 bit number, doubling the number of options available.
As this is required for the kprobe topic branches as well as the tracing
topic branch, a separate branch was created and merged into both.
- Make trace_user_fault_read() available for the rest of tracing
The function trace_user_fault_read() is used by trace_marker file read to
allow reading user space to be done fast and without locking or
allocations. Make this available so that the system call trace events can
use it too.
- Have system call trace events read user space values
Now that the system call trace events callbacks are called in a faultable
context, take advantage of this and read the user space buffers for
various system calls. For example, show the path name of the openat system
call instead of just showing the pointer to that path name in user space.
Also show the contents of the buffer of the write system call. Several
system call trace events are updated to make tracing into a light weight
strace tool for all applications in the system.
- Update perf system call tracing to do the same
- And a config and syscall_user_buf_size file to control the size of the buffer
Limit the amount of data that can be read from user space. The default
size is 63 bytes but that can be expanded to 165 bytes.
- Allow the persistent ring buffer to print system calls normally
The persistent ring buffer prints trace events by their type and ignores
the print_fmt. This is because the print_fmt may change from kernel to
kernel. As the system call output is fixed by the system call ABI itself,
there's no reason to limit that. This makes reading the system call events
in the persistent ring buffer much nicer and easier to understand.
- Add options to show text offset to function profiler
The function profiler that counts the number of times a function is hit
currently lists all functions by its name and offset. But this becomes
ambiguous when there are several functions with the same name. Add a
tracing option that changes the output to be that of _text+offset
instead. Now a user space tool can use this information to map the
_text+offset to the unique function it is counting.
- Report bad dynamic event command
If a bad command is passed to the dynamic_events file, report it properly
in the error log.
- Clean up tracer options
Clean up the tracer option code a bit, by removing some useless code and
also using switch statements instead of a series of if statements.
- Have tracing options be instance specific
Tracers can have their own options (function tracer, irqsoff tracer,
function graph tracer, etc). But now that the same tracer can be enabled
in multiple trace instances, their options are still global. The API is
per instance, thus changing one affects other instances. This isn't even
consistent, as the option take affect differently depending on when an
tracer started in an instance. Make the options for instances only affect
the instance it is changed under.
- Optimize pid_list lock contention
Whenever the pid_list is read, it uses a spin lock. This happens at every
sched switch. Taking the lock at sched switch can be removed by instead
using a seqlock counter.
- Clean up the trace trigger structures
The trigger code uses two different structures to implement a single
tigger. This was due to trying to reuse code for the two different types
of triggers (always on trigger, and count limited trigger). But by adding
a single field to one structure, the other structure could be absorbed
into the first structure making he code easier to understand.
- Create a bulk garbage collector for trace triggers
If user space has triggers for several hundreds of events and then removes
them, it can take several seconds to complete. This is because each
removal calls the slow tracepoint_synchronize_unregister() that can take
hundreds of milliseconds to complete. Instead, create a helper thread that
will do the clean up. When a trigger is removed, it will create the
kthread if it isn't already created, and then add the trigger to a llist.
The kthread will take the items off the llist, call
tracepoint_synchronize_unregister(), and then remove the items it took
off. It will then check if there's more items to free before sleeping.
This makes user space removing all these triggers to finish in less than a
second.
- Allow function tracing of some of the tracing infrastructure code
Because the tracing code can cause recursion issues if it is traced by the
function tracer the entire tracing directory disables function tracing.
But not all of tracing causes issues if it is traced. Namely, the event
tracing code. Add a config that enables some of the tracing code to be
traced to help in debugging it. Note, when this is enabled, it does add
noise to general function tracing, especially if events are enabled as
well (which is a common case).
- Add boot-time backup instance for persistent buffer
The persistent ring buffer is used mostly for kernel crash analysis in the
field. One issue is that if there's a crash, the data in the persistent
ring buffer must be read before tracing can begin using it. This slows
down the boot process. Once tracing starts in the persistent ring buffer,
the old data must be freed and the addresses no longer match and old
events can't be in the buffer with new events.
Create a way to create a backup buffer that copies the persistent ring
buffer at boot up. Then after a crash, the always on tracer can begin
immediately as well as the normal boot process while the crash analysis
tooling uses the backup buffer. After the backup buffer is finished being
read, it can be removed.
- Enable function graph args and return address options at the same time
Currently the when reading of arguments in the function graph tracer is
enabled, the option to record the parent function in the entry event can
not be enabled. Update the code so that it can.
- Add new struct_offset() helper macro
Add a new macro that takes a pointer to a structure and a name of one of
its members and it will return the offset of that member. This allows the
ring buffer code to simplify the following:
From: size = struct_size(entry, buf, cnt - sizeof(entry->id));
To: size = struct_offset(entry, id) + cnt;
There should be other simplifications that this macro can help out with as
well.

Detect unused tracepoints for v6.19:
If a tracepoint is defined but never used (TRACE_EVENT() created but no
trace_<tracepoint>() called), it can take up to or more than 5K of memory
each. This can add up as there are around a hundred unused tracepoints with
various configs. That is 500K of wasted memory.
Add a make build parameter of "UT=1" to have the build warn if an unused
tracepoint is detected in the build. This allows detection of unused
tracepoints to be upstream so that outreachy and the mentoring project can
have new developers look for fixing them, without having these warnings
suddenly show up when someone upgrades their kernel. When all known unused
tracepoints are removed, then the "UT=1" build parameter can be removed and
unused tracepoints will always warn. This will catch new unused tracepoints
after the current ones have been removed.
- Separate out elf functions from sorttable.c
Move out the ELF parsing functions from sorttable.c so that the tracing
tooling can use it.
- Add a tracepoint verifier tool to the build process
If "UT=1" is added to the kernel command line, any unused tracepoints will
trigger a warning at build time.
- Do not warn about unused tracepoints for tracepoints that are exported
There are sever cases where a tracepoint is created by the kernel and used
by modules. Since there's no easy way to detect if these are truly unused
since the users are in modules, if a tracepoint is exported, assume it
will eventually be used by a module. Note, there's not many exported
tracepoints so this should not be a problem to ignore them.
- Have building of modules also detect unused tracepoints
Do not only check the main vmlinux for unused tracepoints, also check
modules. If a module is defining a tracepoint it should be using it.
- Add the tracepoint-update program to the ignore file
The new tracepoint-update program needs to be ignored by git.

rtla updaets for v6.19:
- Officially add Tomas Glozar as a maintainer to RTLA tool
- Add for_each_monitored_cpu() helper
In multiple places, RTLA tools iterate over the list of CPUs running
tracer threads.
Use single helper instead of repeating the for/if combination.
- Remove unused variable option_index in argument parsing
RTLA tools use getopt_long() for argument parsing. For its last
argument, an unused variable "option_index" is passed.
Remove the variable and pass NULL to getopt_long() to shorten
the naturally long parsing functions, and make them more readable.
- Fix unassigned nr_cpus after code consolidation
In recent code consolidation, timerlat tool cleanup, previously
implemented separately for each tool, was moved to a common function
timerlat_free().
The cleanup relies on nr_cpus being set. This was not done in the new
function, leaving the variable uninitialized.
Initialize the variable properly, and remove silencing of compiler
warning for uninitialized variables.
- Stop tracing on user latency in BPF mode
Despite the name, rtla-timerlat's -T/--thread option sets timerlat's
stop_tracing_total_us option, which also stops tracing on
return-from-user latency, not only on thread latency.
Implement the same behavior also in BPF sample collection stop tracing
handler to avoid a discrepancy and restore correspondence of behavior
with the equivalent option of cyclictest.
- Fix threshold actions always triggering
A bug in threshold action logic caused the action to execute even
if tracing did not stop because of threshold.
Fix the logic to stop correctly.
- Fix few minor issues in tests
Extend tests that were shown to need it to 5s, fix osnoise test
calling timerlat by mistake, and use new, more reliable output
checking in timerlat's "top stop at failed action" test.
- Do not print usage on argument parsing error
RTLA prints the entire usage message on encountering errors in
argument parsing, like a malformed CPU list.
The usage message has gotten too long. Instead of printing it,
use newly added fatal() helper function to simply exit with
the error message, excluding the usage.
- Fix unintuitive -C/--cgroup interface
"-C cgroup" and "--cgroup cgroup" are invalid syntax, despite that
being a common way to specify an option with argument. Moreover,
using them fails silently and no cgroup is set.
Create new helper function to unify the handling of all such options
and allow all of:
-Xsomething
-X=something
-X something
as well as the equivalent for the long option.
- Fix -a overriding -t argument filename
Fix a bug where -a following -t custom_file.txt overrides the custom
filename with the default timerlat_trace.txt.
- Stop tracing correctly on multiple events at once
In some race scenarios, RTLA BPF sample collection might send multiple
stop tracing events via the BPF ringbuffer at once.
Compare the number of events for != 0 instead of == 1 to cover for
this scenario and stop tracing properly.

Capabilities patch for v6.19
There is only a single commit,
Clarify the rootid_owns_currentns
which introduces no functional change. Ryan Foster had sent a patch
to add testing of the security/commoncap.c:rootid_owns_currentns()
function. The patch pointed out that this function was not as clear
as it should be.
This commit has two purposes:
1. Clarify the intent of the function in the name
2. Split the function so that the base functionality is easier
to test from a kunit test.
This commit has been in linux-next since November 18 with no reported
issues. Ryan has posted an updated test patch based on this commit.

iommufd 6.19 pull request
- Expand IOMMU_IOAS_MAP_FILE to accept a DMABUF exported from VFIO. This
is the first step to broader DMABUF support in iommufd, right now it
only works with VFIO. This closes the last functional gap with classic
VFIO type 1 to safely support PCI peer to peer DMA by mapping the VFIO
device's MMIO into the IOMMU.
- Relax SMMUv3 restrictions on nesting domains to better support qemu's
sequence to have an identity mapping before the vSID is established.

Pull iommufd updates from Jason Gunthorpe:
"This is a pretty consequential cycle for iommufd, though this pull is
not too big. It is based on a shared branch with VFIO that introduces
VFIO_DEVICE_FEATURE_DMA_BUF a DMABUF exporter for VFIO device's MMIO
PCI BARs. This was a large multiple series journey over the last year
and a half.
Based on that work IOMMUFD gains support for VFIO DMABUF's in its
existing IOMMU_IOAS_MAP_FILE, which closes the last major gap to
support PCI peer to peer transfers within VMs.
In Joerg's iommu tree we have the "generic page table" work which aims
to consolidate all the duplicated page table code in every iommu
driver into a single algorithm. This will be used by iommufd to
implement unique page table operations to start adding new features
and improve performance.
In here:
- Expand IOMMU_IOAS_MAP_FILE to accept a DMABUF exported from VFIO.
This is the first step to broader DMABUF support in iommufd, right
now it only works with VFIO. This closes the last functional gap

VFIO updates for v6.19-rc1
- Move libvfio selftest artifacts in preparation of more tightly
coupled integration with KVM selftests. (David Matlack)
- Fix comment typo in mtty driver. (Chu Guangqing)
- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user. (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant
driver. (Raghavendra Rao Ananta)
- Introduce internal callbacks on vfio devices to simplify and
consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
data, removing various ioctl intercepts with a more structured
solution. (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping. (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue.
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers. (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset. (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency. (David Matlack)

IOMMU Updates for Linux v6.19
Including:
- Introduction of the generic IO page-table framework with support for
Intel and AMD IOMMU formats from Jason. This has good potential for
unifying more IO page-table implementations and making future
enhancements more easy. But this also needed quite some fixes during
development. All known issues have been fixed, but my feeling is that
there is a higher potential than usual that more might be needed.
- Intel VT-d updates:
- Use right invalidation hint in qi_desc_iotlb().
- Reduce the scope of INTEL_IOMMU_FLOPPY_WA.
- ARM-SMMU updates:
- Qualcomm device-tree binding updates for Kaanapali and Glymur SoCs
and a new clock for the TBU.
- Fix error handling if level 1 CD table allocation fails.
- Permit more than the architectural maximum number of SMRs for funky
Qualcomm mis-implementations of SMMUv2.
- Mediatek driver:
- MT8189 iommu support.
- Move ARM IO-pgtable selftests to kunit.
- Device leak fixes for a couple of drivers.
- Random smaller fixes and improvements.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
Williams)
- Switch vmd from custom domain number allocator to the common
allocator to prevent a potential race with new non-VMD buses (Dan
Williams)
- Enable Precision Time Measurement (PTM) only if device advertises
support for a relevant role, to prevent invalid PTM Requests that
cause ACS violations that are reported as AER Uncorrectable
Non-Fatal errors (Mika Westerberg)
Resource management:
- Prevent resource tree corruption when BAR resize fails (Ilpo
Järvinen)
- Restore BARs to the original size if a BAR resize fails (Ilpo
Järvinen)
- Remove BAR release from BAR resize attempts by the xe, i915, and
amdgpu drivers so the PCI core can restore BARs if the resize fails
(Ilpo Järvinen)
- Move Resizable BAR code to rebar.c (Ilpo Järvinen)
- Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
Järvinen)
- Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
Järvinen)
Power management and error handling:
- For drivers using PCI legacy suspend, save config state at suspend
so that state (not any earlier state from enumeration, probe, or
error recovery) will be restored when resuming (Lukas Wunner)
- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)
- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)
- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)
- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)
Power control:
- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)
- Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
switch, which must be held in reset after poweron so the pwrctrl
driver can configure the switch via I2C before bringing up the
links (Krishna Chaitanya Chundru)
Endpoint framework:
- Convert the endpoint doorbell test to use a threaded IRQ to fix a
'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)
- Add endpoint VNTB MSI doorbell support to reduce latency between
host and endpoint (Frank Li)
New native PCIe controller drivers:
- Add CIX Sky1 host controller DT binding and driver (Hans Zhang)
- Add NXP S32G host controller DT binding and driver (Vincent
Guittot)
- Add Renesas RZ/G3S host controller DT binding and driver (Claudiu
Beznea)
- Add SpacemiT K1 host controller DT binding and driver (Alex Elder)
Amlogic Meson PCIe controller driver:
- Update DT binding to name DBI region 'dbi', not 'elbi', and update
driver to support both (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Move struct pci_host_bridge allocation from pci_host_common_init()
to callers, which significantly simplifies pcie-apple (Marc
Zyngier)
Broadcom STB PCIe controller driver:
- Disable advertising ASPM L0s support correctly (Jim Quinlan)
- Add a panic/die handler to print diagnostic info in case PCIe
caused an unrecoverable abort (Jim Quinlan)
Cadence PCIe controller driver:
- Add module support for Cadence platform host and endpoint
controller driver (Manikandan K Pillai)
- Split headers into 'legacy' (LGA) and 'high perf' (HPA) to prepare
for new CIX Sky1 driver (Manikandan K Pillai)
MediaTek PCIe controller driver:
- Convert DT binding to YAML schema (Christian Marangi)
- Add Airoha AN7583 DT compatible and driver support (Christian
Marangi)
Qualcomm PCIe controller driver:
- Add Qualcomm Kaanapali to SM8550 DT binding (Qiang Yu)
- Add required 'power-domains' and 'resets' to qcom sa8775p, sc7280,
sc8280xp, sm8150, sm8250, sm8350, sm8450, sm8550, x1e80100 DT
schemas (Krzysztof Kozlowski)
- Look up OPP using both frequency and data rate (not just frequency)
so RPMh votes can account for both (Krishna Chaitanya Chundru)
Rockchip DesignWare PCIe controller driver:
- Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)
STMicroelectronics STM32MP25 PCIe controller driver:
- Fix a race between link training and endpoint register
initialization (Christian Bruel)
- Align endpoint allocations to match the ATU requirements (Christian
Bruel)
Synopsys DesignWare PCIe controller driver:
- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)
- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)
- Configure L1SS support in dw-rockchip when DT says
'supports-clkreq' (Shawn Lin)
TI Keystone PCIe controller driver:
- Fail the probe instead of silently succeeding if ks_pcie_of_data
didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)
- Make keystone buildable as a loadable module, except on ARM32 where
hook_fault_code() is __init (Siddharth Vadapalli)"

EFI updates for v6.19:
- Parse SMBIOS tables in memory directly on Macbooks that do not
implement the EFI SMBIOS protocol
- Obtain EDID information from the primary display while running in the
EFI stub, and expose it via bootparams on x86 (generic method is in
the works, and will likely land during the next cycle)
- Bring CPER handling for ARM systems up to data with the latest EFI
spec changes.
- Various cosmetic changes.

gpio updates for v6.19-rc1
GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot enable
counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone to
bugs (GPIO controllers don't have to use the software node's name as
their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device code
New drivers:
- add a driver for the QIXIS FPGA GPIO controller
Driver improvements:
- use modernized variants of power management macros across a wide array
of drivers in order to avoid having to use the __maybe_unused attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to user-space
in gpio-virtuser (this was previously not possible as this function
returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary calls
to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio
Device-tree bindings:
- document new NXP and Microchip models
Documentation:
- add a comprehensive compatibility and feature list for gpio-pca953x,
which is a great addition as it's probably the most commonly used GPIO
expander driver
- kernel-doc tweaks
Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, lots of various updates to existing ones, some
refactoring support for new models and misc tweaks and fixes.
The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.

firewire updates for v6.19
This release includes two changes for core functions, which affects all
use cases of this subsystem.
- Handle per-device interoperability quirks
It is well known that some devices have quirks affecting
interoperability. To identify such quirks at an early stages of
device detection, the step for reading the configuration ROM contents
has been changed. As a side effect, the entire detection process is
now performed at the basic transaction speed (S100), without no trial
to probe higher supported speeds.
With this change, the following devices should now work with fewer
issues:
- TASCAM FW-1884, FW-1804, and FW-1082
- MOTU Audio Express
- Safer removals of host card
There was a race condition between host card removal and handling of
bus reset events in the workqueue. This appears to be a long standing
issue (for a dozen years or so[1]), and recent changes to use more
workqueues escalate it. To solve it, a new callback has been added to
the 1394 OHCI PCI driver to unregister the interrupt sources and wait
for workqueue completions when removing a card instance.

spi: Updates for v6.19
This release is almost entirely new drivers, with a couple of small
changes in generic code. The biggest individual update is a rename of
the existing Microchip driver and the addition of a new driver for the
silicon SPI controller in their PolarFire SoCs. The overlap between the
soft IP supported by the current driver and this new one is regrettably
all in the IP and not in the register interface offered to software.
- Add a time offset parameter for offloads, allowing them to be defined
in relation to each other. This is useful for IIO type applcations
where you trigger an operation then read the result after a delay.
- Add a tracepoint for flash exec_ops, bringing the flash support more
in line with the debuggability of vanilla SPI.
- Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip
PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm
IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT K1
QuadSPI.
There's also a small set of ASoC cleanups that I mistakenly applied to
the SPI tree and then put more stuff on top of before it was brought to
my attention, sorry about that.

regulator: Updates for v6.19
This is a relatively busy release for the regulator API, as well as a
good collection of new drivers we've got a little bit of core work and a
bunch of cleanup throughout the subsystem:
- Support for propagating undervoltage events to child regulators.
- Undo enables done on supplies when setting enabling regulators via
constraints fails.
- Pull in some gpiolib changes adding support for shared GPIOs to
the gpiolib core, using them to replace the open coded variant of this
that we've had in the regulator API for a long time.
- Support for Fitipower FP9931 and JD9330, Mediatek MT6316, MT6363 and
MT6373, NXP PF1550 and Qualcomm PMH01XX and PMCX0102
The PF1550 support was originally going to go via the MFD tree but
Krzysztof's cleanup work overlapped with it so I pulled in Lee's signed
tag with support for the device.

regmap: Updates for v6.19
Another small update for regmap, we have one new feature plus a little
bit of cleanup:
- Support for sparseness information in the flat cache, allowing users
that really need the performance properties it provides to benefit
from the interface and startup time improvements that sparsness provides
without needing to go all the way to a more fancy data structure.
- Cleanup work from Andy Shevchenko, refactoring the cache interface
in preparation for some future stuff he's working on.

Core MTD changes:
- We must ignore error -ENOENT from parsers on subpartitions which is a
legitimate return value.
- PM support is added to the intel-dg driver.
Raw NAND changes:
- The major change in this MR will be the support for the Allwinner H616
NAND controller, which lead to numerous changes and cleanups in the
driver.
- Another notable change on this driver is the use of
field_get()/field_prep(), but since the global support for this
helpers is going to be merged in the same release as we start using
these helpers, it implies undefining them in the first place to avoid
warnings. Depending on the merging order (Yuri's bitmap branch or
mtd/next), a temporary warning may arise.
- Marvell drivers layout handling changes have also landed, they fix
previous definitions and abuses that have been made previously, which
implied to relax the ECC parameters validation in the core a bit.
- The Cadence NAND controller driver gets NV-DDR interface support.
SPI NAND changes:
- Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.
SPI NOR changes:
- Fix SMPT parsing for S25FS-S flash family. They report variable dummy
cycles for reads. This results in the default of 0 being used. This
works for other Infineon chips, but not for the S25FS-S family. They
need 8 dummy cycles. Add fixup hooks to specify that. Also add fixup
hooks to fix incorrect map ID data in SFDP.
- Add support for a bunch of Winbond flashes. Their block protection
information is not discoverable, so they need to have an entry in the
flash tables to describe that.
- Some cleanups for Micron flash support.
- Add support for Micron mt35xu01gbba.
- Some SPI controllers like the Intel one on the PCI bus do not support
the read CR opcode (0x35). Do not use the opcode if the controller
does not support it.
Aside from these main changes, there is the usual load of API updates,
kdoc fixes, potential memory leaks fixes, etc.
