RISC-V
CPU:
- Expose housekeeping CPUs through /sys/devices/system/cpu/housekeeping
- Print a newline (or 0x0A) instead of '(null)' reading
/sys/devices/system/cpu/nohz_full when nohz_full= is not set
debugfs
- Remove (broken) 'no-mount' mode
- Remove redundant access mode checks in debugfs_get_tree() and
debugfs_create_*() functions

Misc:
- Increase the name size in struct auxiliary_device_id to 40
characters

Pull more SoC driver updates from Arnd Bergmann:
"These updates came a little late, or were based on a later 6.18-rc tag
than the others:
- A new driver for cache management on cxl devices with memory shared
in a coherent cluster. This is part of the drivers/cache/ tree, but
unlike the other drivers that back the dma-mapping interfaces, this
one is needed only during CPU hotplug.
- A shared branch for reset controllers using swnode infrastructure
- Added support for new SoC variants in the Amlogic soc_device
identification

Pull new SoC families update from Arnd Bergmann:
"These three new families of SoC are split out into a separate branch
because they touch multiple parts of the source tree and are better
left separate for the initial merge.
- Black Sesame Technologies C1200 is an automotive SoC using
Cortex-A78 CPU cores
- Anlogic dr1v90 (not to be confused with Amlogic) is an FPGA
platform using a single nuclei ux900 RISC-V core
- Tenstorrent Blackhole is a Neural Processing Unit using custom
"Tensix" cores for computation offload managed by Linux running on
SiFive X280 RISC-V cores.
Support for all three is rather rudimentary at the moment and will get
improved as device drivers are merged through other tree"

Pull SoC devicetree updates from Arnd Bergmann:
"Three new SoCs got added in existing arm64 chip families:
- Renesas R-Car X5H (R8A78000) is a new generation of automotive
SoCs, based on 16 Cortex-A720 (Armv9.2) cores, which makes the the
currently highest-perforance embedded SoC.
- TI AM62L is a new variant of the AM62 family of industrial SoCs,
this one comes without a GPU.
- Qualcomm MSM8937 (Snapdragon 430) is an older mobile phone chip
based on Cortex-A53, and closely related to MSM8917 (Snapdragn
425), which we already support.
In addition, there are a good number of newly supported machines
across SoC families:
- Two Aspeed AST2600 (Cortex-A7) based BMC setups for large servers
- Mobile Phones and tables based on Mediatek MT6582, Nvidia Tegra124,
Qualcomm MSM8937 and Qualcomm MSM8939,
- Two Laptops based on Qualcomm SoCs: one using the older sdm850, the
other using x1p42100.
- One Router based on Rockchips RK3568
- 24 variants of the Enclustra Mercury system-on-module, all based on
32-bit Intel/Altera SocFPGA chips, plus two boards using 64-bit
SocFPGA Agilex chips..
- 30 industrial/embedded boards and single-board computers, using
various chips from NXP, Rockchips, Mediatek, TI, Amlogic, Qualcomm,
Spacemit, and Starfive.
In total there are 783 commits here, the majority of these improving
hardware support and cleaning up devicetree files across the tree,
with the majority of the changes going into the Qualcomm, NXP, Renesas
and Rockchips platforms"

Pull KVM updates from Paolo Bonzini:
"ARM:
- Support for userspace handling of synchronous external aborts
(SEAs), allowing the VMM to potentially handle the abort in a
non-fatal manner
- Large rework of the VGIC's list register handling with the goal of
supporting more active/pending IRQs than available list registers
in hardware. In addition, the VGIC now supports EOImode==1 style
deactivations for IRQs which may occur on a separate vCPU than the
one that acked the IRQ
- Support for FEAT_XNX (user / privileged execute permissions) and
FEAT_HAF (hardware update to the Access Flag) in the software page
table walkers and shadow MMU
- Allow page table destruction to reschedule, fixing long
need_resched latencies observed when destroying a large VM
- Minor fixes to KVM and selftests
Loongarch:
- Get VM PMU capability from HW GCFG register
- Add AVEC basic support
- Use 64-bit register definition for EIOINTC
- Add KVM timer test cases for tools/selftests
RISC/V:
- SBI message passing (MPXY) support for KVM guest
- Give a new, more specific error subcode for the case when in-kernel
AIA virtualization fails to allocate IMSIC VS-file
- Support KVM_DIRTY_LOG_INITIALLY_SET, enabling dirty log gradually
in small chunks
- Fix guest page fault within HLV* instructions
- Flush VS-stage TLB after VCPU migration for Andes cores
s390:
- Always allocate ESCA (Extended System Control Area), instead of
starting with the basic SCA and converting to ESCA with the
addition of the 65th vCPU. The price is increased number of exits
(and worse performance) on z10 and earlier processor; ESCA was
introduced by z114/z196 in 2010
- VIRT_XFER_TO_GUEST_WORK support
- Operation exception forwarding support
- Cleanups
x86:
- Skip the costly "zap all SPTEs" on an MMIO generation wrap if MMIO
SPTE caching is disabled, as there can't be any relevant SPTEs to
zap
- Relocate a misplaced export
- Fix an async #PF bug where KVM would clear the completion queue
when the guest transitioned in and out of paging mode, e.g. when
handling an SMI and then returning to paged mode via RSM
- Leave KVM's user-return notifier registered even when disabling
virtualization, as long as kvm.ko is loaded. On reboot/shutdown,
keeping the notifier registered is ok; the kernel does not use the
MSRs and the callback will run cleanly and restore host MSRs if the
CPU manages to return to userspace before the system goes down
- Use the checked version of {get,put}_user()
- Fix a long-lurking bug where KVM's lack of catch-up logic for
periodic APIC timers can result in a hard lockup in the host
- Revert the periodic kvmclock sync logic now that KVM doesn't use a
clocksource that's subject to NTP corrections
- Clean up KVM's handling of MMIO Stale Data and L1TF, and bury the
latter behind CONFIG_CPU_MITIGATIONS
- Context switch XCR0, XSS, and PKRU outside of the entry/exit fast
path; the only reason they were handled in the fast path was to
paper of a bug in the core #MC code, and that has long since been
fixed
- Add emulator support for AVX MOV instructions, to play nice with
emulated devices whose guest drivers like to access PCI BARs with
large multi-byte instructions
x86 (AMD):
- Fix a few missing "VMCB dirty" bugs
- Fix the worst of KVM's lack of EFER.LMSLE emulation
- Add AVIC support for addressing 4k vCPUs in x2AVIC mode
- Fix incorrect handling of selective CR0 writes when checking
intercepts during emulation of L2 instructions
- Fix a currently-benign bug where KVM would clobber SPEC_CTRL[63:32]
on VMRUN and #VMEXIT
- Fix a bug where KVM corrupt the guest code stream when re-injecting
a soft interrupt if the guest patched the underlying code after the
VM-Exit, e.g. when Linux patches code with a temporary INT3
- Add KVM_X86_SNP_POLICY_BITS to advertise supported SNP policy bits
to userspace, and extend KVM "support" to all policy bits that
don't require any actual support from KVM
x86 (Intel):
- Use the root role from kvm_mmu_page to construct EPTPs instead of
the current vCPU state, partly as worthwhile cleanup, but mostly to
pave the way for tracking per-root TLB flushes, and elide EPT
flushes on pCPU migration if the root is clean from a previous
flush
- Add a few missing nested consistency checks
- Rip out support for doing "early" consistency checks via hardware
as the functionality hasn't been used in years and is no longer
useful in general; replace it with an off-by-default module param
to WARN if hardware fails a check that KVM does not perform
- Fix a currently-benign bug where KVM would drop the guest's
SPEC_CTRL[63:32] on VM-Enter
- Misc cleanups
- Overhaul the TDX code to address systemic races where KVM (acting
on behalf of userspace) could inadvertantly trigger lock contention
in the TDX-Module; KVM was either working around these in weird,
ugly ways, or was simply oblivious to them (though even Yan's
devilish selftests could only break individual VMs, not the host
kernel)
- Fix a bug where KVM could corrupt a vCPU's cpu_list when freeing a
TDX vCPU, if creating said vCPU failed partway through
- Fix a few sparse warnings (bad annotation, 0 != NULL)
- Use struct_size() to simplify copying TDX capabilities to userspace
- Fix a bug where TDX would effectively corrupt user-return MSR
values if the TDX Module rejects VP.ENTER and thus doesn't clobber
host MSRs as expected
Selftests:
- Fix a math goof in mmu_stress_test when running on a single-CPU
system/VM
- Forcefully override ARCH from x86_64 to x86 to play nice with
specifying ARCH=x86_64 on the command line
- Extend a bunch of nested VMX to validate nested SVM as well
- Add support for LA57 in the core VM_MODE_xxx macro, and add a test
to verify KVM can save/restore nested VMX state when L1 is using
5-level paging, but L2 is not
- Clean up the guest paging code in anticipation of sharing the core
logic for nested EPT and nested NPT
guest_memfd:
- Add NUMA mempolicy support for guest_memfd, and clean up a variety
of rough edges in guest_memfd along the way
- Define a CLASS to automatically handle get+put when grabbing a
guest_memfd from a memslot to make it harder to leak references
- Enhance KVM selftests to make it easer to develop and debug
selftests like those added for guest_memfd NUMA support, e.g. where
test and/or KVM bugs often result in hard-to-debug SIGBUS errors
- Misc cleanups
Generic:
- Use the recently-added WQ_PERCPU when creating the per-CPU
workqueue for irqfd cleanup
- Fix a goof in the dirty ring documentation
- Fix choice of target for directed yield across different calls to
kvm_vcpu_on_spin(); the function was always starting from the first
vCPU instead of continuing the round-robin search"

Pull persistent dentry infrastructure and conversion from Al Viro:
"Some filesystems use a kinda-sorta controlled dentry refcount leak to
pin dentries of created objects in dcache (and undo it when removing
those). A 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"

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Extend tracing option mask to 64 bits
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 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

Pull rtla trace tooling updates from Steven Rostedt:
- 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.

Pull iommu updates from Joerg Roedel:
- 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:

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)

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)"

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.
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 spi updates from Mark Brown:
"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"

Pull mtd updates from Miquel Raynal:
"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 is the support for the Allwinner H616 NAND
controller, which lead to numerous changes and cleanups in the
driver.
- Another notable change in this driver is the use of field_get() and
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, we undefine them in the first place to avoid warnings.
- 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.

kdoc fixes, potential memory leaks fixes, etc"

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Replace busylock at the Tx queuing layer with a lockless list.
Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.
Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.
Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for
packets.
- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of
RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.

git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Add support for 'syn'.
Syn is a parsing library for parsing a stream of Rust tokens into a
syntax tree of Rust source code.
Currently this library is geared toward use in Rust procedural
macros, but contains some APIs that may be useful more generally.
'syn' allows us to greatly simplify writing complex macros such as
'pin-init' (Benno has already prepared the 'syn'-based version). We
will use it in the 'macros' crate too.
'syn' is the most downloaded Rust crate (according to crates.io),
and it is also used by the Rust compiler itself. While the amount
of code is substantial, there should not be many updates needed for
these crates, and even if there are, they should not be too big,
e.g. +7k -3k lines across the 3 crates in the last year.
'syn' requires two smaller dependencies: 'quote' and 'proc-macro2'.
I only modified their code to remove a third dependency
('unicode-ident') and to add the SPDX identifiers. The code can be
easily verified to exactly match upstream with the provided
scripts.
They are all licensed under "Apache-2.0 OR MIT", like the other
vendored 'alloc' crate we had for a while.
Please see the merge commit with the cover letter for more context.
- Allow 'unreachable_pub' and 'clippy::disallowed_names' for
doctests.
Examples (i.e. doctests) may want to do things like show public
items and use names such as 'foo'.
Nevertheless, we still try to keep examples as close to real code
as possible (this is part of why running Clippy on doctests is
important for us, e.g. for safety comments, which userspace Rust
does not support yet but we are stricter).
'kernel' crate:
- Replace our custom 'CStr' type with 'core::ffi::CStr'.
Using the standard library type reduces our custom code footprint,
and we retain needed custom functionality through an extension
trait and a new 'fmt!' macro which replaces the previous 'core'
import.
This started in 6.17 and continued in 6.18, and we finally land the
replacement now. This required quite some stamina from Tamir, who
split the changes in steps to prepare for the flag day change here.
- Replace 'kernel::c_str!' with C string literals.
C string literals were added in Rust 1.77, which produce '&CStr's
(the 'core' one), so now we can write:
c"hi"
instead of:
c_str!("hi")
- Add 'num' module for numerical features.
It includes the 'Integer' trait, implemented for all primitive
integer types.
It also includes the 'Bounded' integer wrapping type: an integer
value that requires only the 'N' least significant bits of the
wrapped type to be encoded:
// An unsigned 8-bit integer, of which only the 4 LSBs are used.
let v = Bounded::<u8, 4>::new::<15>();
assert_eq!(v.get(), 15);
'Bounded' is useful to e.g. enforce guarantees when working with
bitfields that have an arbitrary number of bits.
Values can also be constructed from simple non-constant expressions
or, for more complex ones, validated at runtime.
'Bounded' also comes with comparison and arithmetic operations
(with both their backing type and other 'Bounded's with a
compatible backing type), casts to change the backing type,
extending/shrinking and infallible/fallible conversions from/to
primitives as applicable.
- 'rbtree' module: add immutable cursor ('Cursor').
It enables to use just an immutable tree reference where
appropriate. The existing fully-featured mutable cursor is renamed
to 'CursorMut'.
kallsyms:
- Fix wrong "big" kernel symbol type read from procfs.
'pin-init' crate:
- A couple minor fixes (Benno asked me to pick these patches up for
him this cycle).
Documentation:
- Quick Start guide: add Debian 13 (Trixie).
Debian Stable is now able to build Linux, since Debian 13 (released
2025-08-09) packages Rust 1.85.0, which is recent enough.
We are planning to propose that the minimum supported Rust version
in Linux follows Debian Stable releases, with Debian 13 being the
first one we upgrade to, i.e. Rust 1.85.
MAINTAINERS:
- Add entry for the new 'num' module.
- Remove Alex as Rust maintainer: he hasn't had the time to
contribute for a few years now, so it is a no-op change in
practice.
And a few other cleanups and improvements"
