There's a lot of unnecessary whitespace damage in this
file: space before tabs, etc., that has no formatting
or readability effect or advantages.
Fix them.

boot.rst
Sphinx reports htmldocs warnings:
Documentation/arch/x86/boot.rst:437: ERROR: Malformed table.
Text in column margin in table line 2.
The table header defined the first column width as 2 characters ("=="),
which is too narrow for entries like "0x10" and "0x13". This caused the
text to spill into the margin, triggering a docutils parsing failure.
Fix it by extending the first column of assigned boot loader ID to 4
characters ("====") to fit the widest entries.
Fixes: 1c3377bee212 ("x86/boot/Documentation: Prefix hexadecimal literals with 0x")

Pull f2fs updates from Jaegeuk Kim:
"This series focuses on minor clean-ups and performance optimizations
across sysfs, documentation, debugfs, tracepoints, slab allocation,
and GC. Furthermore, it resolves several corner-case bugs caught by
xfstests, as well as issues related to 16KB page support and
f2fs_enable_checkpoint.
Enhancement:
- wrap ASCII tables in literal blocks to fix LaTeX build
- optimize trace_f2fs_write_checkpoint with enums
- support to show curseg.next_blkoff in debugfs
- add a sysfs entry to show max open zones
- add fadvise tracepoint
- use global inline_xattr_slab instead of per-sb slab cache
- set default valid_thresh_ratio to 80 for zoned devices
- maintain one time GC mode is enabled during whole zoned GC cycle
Bug fix:
- ensure node page reads complete before f2fs_put_super() finishes
- do not account invalid blocks in get_left_section_blocks()
- revert summary entry count from 2048 to 512 in 16kb block support
- detect recoverable inode during dryrun of find_fsync_dnodes()
- fix age extent cache insertion skip on counter overflow
- add sanity checks before unlinking and loading inodes
- ensure minimum trim granularity accounts for all devices
- block cache/dio write during f2fs_enable_checkpoint()
- propagate error from f2fs_enable_checkpoint()
- invalidate dentry cache on failed whiteout creation
- avoid updating compression context during writeback
- avoid updating zero-sized extent in extent cache
- avoid potential deadlock"

Pull pin control updates from Linus Walleij:
"The technical details below. For me the CIX Semi and Axis
Communications ARTPEC-9 SoCs were the most interesting new drivers in
this merge window.
Core changes:
- Handle per-direction skew control in the generic pin config
- Drop the pointless subsystem boilerplate banner message during
boot. Less noise in the console. It's available as debug message if
someone really want it
New drivers:
- Samsung Exynos 8890 SoC support
- Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
These guys literally live next door to me, ARTPEC spells out "Axis
Real-Time Picture Encoding Chip" and is tailored for camera image
streams and is something they have evolved for a quarter of a
century
- Mediatek MT6878 SoC support
- Qualcomm Glymur PMIC support (mostly just compatible strings)
- Qualcomm Kaanapali SoC TLMM support
- Microchip pic64gx "gpio2" SoC support
- Microchip Polarfire "iomux0" SoC support
- CIX Semiconductors SKY1 SoC support
- Rockchip RK3506 SoC support
- Airhoa AN7583 chip support
Improvements:
- Improvements for ST Microelectronics STM32 handling of skew
settings so input and output can have different skew settings
- A whole bunch of device tree binding cleanups: Marvell Armada and
Berlin, Actions Semiconductor S700 and S900, Broadcom Northstar 2
(NS2), Bitmain BM1880 and Spreadtrum SC9860 are moved over to
schema"

Pull clk updates from Stephen Boyd:
"This is entirely SoC clk drivers.
The majority diff wise is for the new Rockchip and Qualcomm clk
drivers which is mostly lines and lines of data structures to describe
the clk hardware in these SoCs. Beyond those two, Renesas continues to
incrementally add clks to their SoC drivers, causing them to show up
higher in the diffstat this time because they added quite a few clks
all over the place.
Overall it is a semi-quiet release that has some new clk drivers and
the usual fixes for clock data that was wrong or missing and
non-critical cleanups that plug error paths or fix typos.
New Drivers:
- Qualcomm IPQ5424 Network Subsystem Clock Controller
- Qualcomm SM8750 Video Clock Controller
- Rockchip RV1126B and RK3506 clock drivers
- i.MX8ULP SIM LPAV clock driver

increases the flexibility of KEXEC Handover. Also preparation for LUO
- "Live Update Orchestrator" (Pasha Tatashin)
is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.

Pull nfsd updates from Chuck Lever:
- Mike Snitzer's mechanism for disabling I/O caching introduced in
v6.18 is extended to include using direct I/O. The goal is to further
reduce the memory footprint consumed by NFS clients accessing large
data sets via NFSD.
- The NFSD community adopted a maintainer entry profile during this
cycle. See
Documentation/filesystems/nfs/nfsd-maintainer-entry-profile.rst
- Work continues on hardening NFSD's implementation of the pNFS block
layout type. This type enables pNFS clients to directly access the
underlying block devices that contain an exported file system,
reducing server overhead and increasing data throughput.
- The remaining patches are clean-ups and minor optimizations. Many
thanks to the contributors, reviewers, testers, and bug reporters who
participated during the v6.19 NFSD development cycle.

Pull PCIe Link Encryption and Device Authentication from Dan Williams:
"New PCI infrastructure and one architecture implementation for PCIe
link encryption establishment via platform firmware services.
This work is the result of multiple vendors coming to consensus on
some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
three vendor implementations, although only one is included in this
pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
changes have an ack from Tom, and the iommu/amd/ changes have an ack
from Joerg.
PCIe link encryption is made possible by the soup of acronyms
mentioned in the shortlog below. Link Integrity and Data Encryption
(IDE) is a protocol for installing keys in the transmitter and
receiver at each end of a link. That protocol is transported over Data
Object Exchange (DOE) mailboxes using PCI configuration requests.
The aspect that makes this a "platform firmware service" is that the
key provisioning and protocol is coordinated through a Trusted
Execution Envrionment (TEE) Security Manager (TSM). That is either
firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
software (Intel TDX Connect / ARM CCA) running in a protected CPU
mode.
Now, the only reason to ask a TSM to run this protocol and install the
keys rather than have a Linux driver do the same is so that later, a
confidential VM can ask the TSM directly "can you certify this
device?".
That precludes host Linux from provisioning its own keys, because host
Linux is outside the trust domain for the VM. It also turns out that
all architectures, save for one, do not publish a mechanism for an OS
to establish keys in the root port. So "TSM-established link
encryption" is the only cross-architecture path for this capability
for the foreseeable future.
This unblocks the other arch implementations to follow in v6.20/v7.0,
once they clear some other dependencies, and it unblocks the next
phase of work to implement the end-to-end flow of confidential device
assignment. The PCIe specification calls this end-to-end flow Trusted
Execution Environment (TEE) Device Interface Security Protocol
(TDISP).
In the meantime, Linux gets a link encryption facility which has
practical benefits along the same lines as memory encryption. It
authenticates devices via certificates and may protect against
interposer attacks trying to capture clear-text PCIe traffic.
Summary:
- Introduce the PCI/TSM core for the coordination of device
authentication, link encryption and establishment (IDE), and later
management of the device security operational states (TDISP).
Notify the new TSM core layer of PCI device arrival and departure
- Add a low level TSM driver for the link encryption establishment
capabilities of the AMD SEV-TIO architecture
- Add a library of helpers TSM drivers to use for IDE establishment
and the DOE transport
- Add skeleton support for 'bind' and 'guest_request' operations in
support of TDISP"

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

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 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)"

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"

No callers check the return code, and that's a good thing. Doing so
would be racy and unhelpful.
Drop the return code entirely, so we don't make anyone think about its

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
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.
Aside from these main changes, there is the usual load of API updates,
kdoc fixes, potential memory leaks fixes, etc"

Use-after-free and double-free bugs can be very difficult to track down.
The kernel is good at tracking these and preventing bad pages from being
used/created through simple checks gated behind "check_pages_enabled".
Currently, the only ways to enable this flag is by building with
CONFIG_DEBUG_VM, or as a side effect of other checks such as
init_on_{alloc, free}, page_poisoning, or debug_pagealloc among others.
These solutions are powerful, but may often be too coarse in balancing
the performance vs. safety that a user may want, particularly in
latency-sensitive production environments.
Introduce a new boot parameter "check_pages", which enables page checking
with no other side effects. It takes kstrbool-able inputs as an argument
(i.e. 0/1, true/false, on/off, ...). This patch is backwards-compatible;
setting CONFIG_DEBUG_VM still enables page checking.

Pull drm updates from Dave Airlie:
"There was a rather late merge of a new color pipeline feature, that
some userspace projects are blocked on, and has seen a lot of work in

Sphinx's LaTeX builder fails when converting the nested ASCII tables in
f2fs.rst, producing the following error:
"Markup is unsupported in LaTeX: longtable does not support nesting a table."
Wrap the affected ASCII tables in literal code blocks to force Sphinx to
render them verbatim. This prevents nested longtables and fixes the PDF
build failure on Sphinx 8.2.x.

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.

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"

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Allow creaing nbcon console drivers with an unsafe write_atomic()
callback that can only be called by the final nbcon_atomic_flush_unsafe().
Otherwise, the driver would rely on the kthread.
It is going to be used as the-best-effort approach for an
experimental nbcon netconsole driver, see
https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org
Note that a safe .write_atomic() callback is supposed to work in NMI
context. But some networking drivers are not safe even in IRQ
context:
https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35
In an ideal world, all networking drivers would be fixed first and
the atomic flush would be blocked only in NMI context. But it brings
the question how reliable networking drivers are when the system is
in a bad state. They might block flushing more reliable serial
consoles which are more suitable for serious debugging anyway.
- Allow to use the last 4 bytes of the printk ring buffer.
- Prevent queuing IRQ work and block printk kthreads when consoles are
suspended. Otherwise, they create non-necessary churn or even block
the suspend.
- Release console_lock() between each record in the kthread used for
legacy consoles on RT. It might significantly speed up the boot.
- Release nbcon context between each record in the atomic flush. It
prevents stalls of the related printk kthread after it has lost the
ownership in the middle of a record
- Add support for NBCON consoles into KDB
- Add %ptsP modifier for printing struct timespec64 and use it where
possible

Pull RCU updates from Frederic Weisbecker:
"SRCU:
- Properly handle SRCU readers within IRQ disabled sections in tiny
SRCU
- Preparation to reimplement RCU Tasks Trace on top of SRCU fast:
- Introduce API to expedite a grace period and test it through
rcutorture
- Split srcu-fast in two flavours: SRCU-fast and SRCU-fast-updown.
Both are still targeted toward faster readers (without full
barriers on LOCK and UNLOCK) at the expense of heavier write
side (using full RCU grace period ordering instead of simply
full ordering) as compared to "traditional" non-fast SRCU. But
those srcu-fast flavours are going to be optimized in two
different ways:
- SRCU-fast will become the reimplementation basis for
RCU-TASK-TRACE for consolidation. Since RCU-TASK-TRACE must
be NMI safe, SRCU-fast must be as well.
- SRCU-fast-updown will be needed for uretprobes code in order
to get rid of the read-side memory barriers while still
allowing entering the reader at task level while exiting it
in a timer handler. It is considered semaphore-like in that
it can have different owners between LOCK and UNLOCK.
However it is not NMI-safe.
The actual optimizations are work in progress for the next
cycle. Only the new interfaces are added for now, along with
related torture and scalability test code.
- Create/document/debug/torture new proper initializers for RCU fast:
DEFINE_SRCU_FAST() and init_srcu_struct_fast()
This allows for using right away the proper ordering on the write
side (either full ordering or full RCU grace period ordering)
without waiting for the read side to tell which to use.
This also optimizes the read side altogether with moving flavour
debug checks under debug config and with removing a costly RmW
operation on their first call.
- Make some diagnostic functions tracing safe
Refscale:
- Add performance testing for common context synchronizations
(Preemption, IRQ, Softirq) and per-cpu increments. Those are
relevant comparisons against SRCU-fast read side APIs, especially
as they are planned to synchronize further tracing fast-path code
Miscellanous:
- In order to prepare the layout for nohz_full work deferral to user
exit, the context tracking state must shrink the counter of
transitions to/from RCU not watching. The only possible hazard is
to trigger wrap-around more easily, delaying a bit grace periods
when that happens. This should be a rare event though. Yet add
debugging and torture code to test that assumption
- Fix memory leak on locktorture module
- Annotate accesses in rculist_nulls.h to prevent from KCSAN
warnings. On recent discussions, we also concluded that all those
WRITE_ONCE() and READ_ONCE() on list APIs deserve appropriate
comments. Something to be expected for the next cycle
- Provide a script to apply several configs to several commits with
torture
- Allow torture to reuse a build directory in order to save needless
rebuild time
- Various cleanups"

Pull documentation updates from Jonathan Corbet:
"This has been another busy cycle for documentation, with a lot of
build-system thrashing. That work should slow down from here on out.
- The various scripts and tools for documentation were spread out in
several directories; now they are (almost) all coalesced under
tools/docs/. The holdout is the kernel-doc script, which cannot be
easily moved without some further thought.
- As the amount of Python code increases, we are accumulating modules
that are imported by multiple programs. These modules have been
pulled together under tools/lib/python/ -- at least, for
documentation-related programs. There is other Python code in the
tree that might eventually want to move toward this organization.
- The Perl kernel-doc.pl script has been removed. It is no longer
used by default, and nobody has missed it, least of all anybody who
actually had to look at it.
- The docs build was controlled by a complex mess of makefilese that
few dared to touch. Mauro has moved that logic into a new program
(tools/docs/sphinx-build-wrapper) that, with any luck at all, will
be far easier to understand and maintain.
- The get_feat.pl program, used to access information under
Documentation/features/, has been rewritten in Python, bringing an
end to the use of Perl in the docs subsystem.
- The top-level README file has been reorganized into a more
reader-friendly presentation.

The x86 bootloader ID specification text uses hexadecimal
values without a 0x prefix:
D kexec-tools
E Extended (see ext_loader_type)
F Special (0xFF = undefined)
10 Reserved
11 Minimal Linux Bootloader
<http://sebastian-plotz.blogspot.de>
12 OVMF UEFI virtualization stack
13 barebox
Which beyond the ambiguity of '13' in isolation, also
made me fail a grep -wi '0xd' when I was looking for
the kexec bootloader ID definition and caused quite
a bit of head-scratching before I found out why it
didn't show up.
Furthermore, the actual explanatory text uses the 0x
prefix:
For boot loader IDs above T = 0xD, write T = 0xE to this field and
write the extended ID minus 0x10 to the ext_loader_type field.
Similarly, the ext_loader_ver field can be used to provide more than
four bits for the bootloader version.
So make it all both unambiguous, easy to grep and consistent
across the entire documentation by prefixing the IDs with 0x.

Extracting empty examples results in just the empty template being
generated and then validated. That's pointless and not free, so filter
out the schemas without any examples from the targets.
There's currently a little less than 10% of the binding schema files
without examples. Removing them improves the build time by ~6%.

Pull crypto library updates from Eric Biggers:
"This is the main crypto library pull request for 6.19. It includes:
- Add SHA-3 support to lib/crypto/, including support for both the
hash functions and the extendable-output functions. Reimplement the
existing SHA-3 crypto_shash support on top of the library.
This is motivated mainly by the upcoming support for the ML-DSA
signature algorithm, which needs the SHAKE128 and SHAKE256
functions. But even on its own it's a useful cleanup.
This also fixes the longstanding issue where the
architecture-optimized SHA-3 code was disabled by default.
- Add BLAKE2b support to lib/crypto/, and reimplement the existing
BLAKE2b crypto_shash support on top of the library.
This is motivated mainly by btrfs, which supports BLAKE2b
checksums. With this change, all btrfs checksum algorithms now have
library APIs. btrfs is planned to start just using the library
directly.
This refactor also improves consistency between the BLAKE2b code
and BLAKE2s code. And as usual, it also fixes the issue where the
architecture-optimized BLAKE2b code was disabled by default.
- Add POLYVAL support to lib/crypto/, replacing the existing POLYVAL
support in crypto_shash. Reimplement HCTR2 on top of the library.
This simplifies the code and improves HCTR2 performance. As usual,
it also makes the architecture-optimized code be enabled by
default. The generic implementation of POLYVAL is greatly improved
as well.

- Add FIPS self-tests for SHA-1, SHA-2, and SHA-3"

Pull power management updates from Rafael Wysocki:
"There are quite a few interesting things here, including new hardware
support, new features, some bug fixes and documentation updates. In
addition, there are a usual bunch of minor fixes and cleanups all

Pull arm64 updates from Catalin Marinas:
"These are the arm64 updates for 6.19.
The biggest part is the Arm MPAM driver under drivers/resctrl/.
There's a patch touching mm/ to handle spurious faults for huge pmd
(similar to the pte version). The corresponding arm64 part allows us
to avoid the TLB maintenance if a (huge) page is reused after a write
fault. There's EFI refactoring to allow runtime services with
preemption enabled and the rest is the usual perf/PMU updates and
several cleanups/typos.
Summary:
Core features:
- Basic Arm MPAM (Memory system resource Partitioning And Monitoring)
driver under drivers/resctrl/ which makes use of the fs/rectrl/ API
Perf and PMU:
- Avoid cycle counter on multi-threaded CPUs
- Extend CSPMU device probing and add additional filtering support
for NVIDIA implementations
- Add support for the PMUs on the NoC S3 interconnect
- Add additional compatible strings for new Cortex and C1 CPUs
- Add support for data source filtering to the SPE driver
- Add support for i.MX8QM and "DB" PMU in the imx PMU driver
Memory managemennt:
- Avoid broadcast TLBI if page reused in write fault
- Elide TLB invalidation if the old PTE was not valid
- Drop redundant cpu_set_*_tcr_t0sz() macros
- Propagate pgtable_alloc() errors outside of __create_pgd_mapping()
- Propagate return value from __change_memory_common()
ACPI and EFI:
- Call EFI runtime services without disabling preemption
- Remove unused ACPI function
Miscellaneous:
- ptrace support to disable streaming on SME-only systems
- Improve sysreg generation to include a 'Prefix' descriptor
- Replace __ASSEMBLY__ with __ASSEMBLER__
- Align register dumps in the kselftest zt-test
- Remove some no longer used macros/functions

of hotplug memory, allowing with and without memmap_on_memory
support. This makes the way memory hotplug is handled on s390 much
more similar to other architectures
- Remove compat support. There shouldn't be any compat user space
around anymore, therefore get rid of a lot of code which also doesn't
need to be tested anymore
- Add stackprotector support. GCC 16 will get new compiler options,
which allow to generate code required for kernel stackprotector
support
- Merge pai_crypto and pai_ext PMU drivers into a new driver. This
removes a lot of duplicated code. The new driver is also extendable
and allows to support new PMUs
- Add driver override support for AP queues
- Rework and extend zcrypt and AP trace events to allow for tracing of
crypto requests
- Support block sizes larger than 65535 bytes for CCW tape devices

Pull rseq updates from Thomas Gleixner:
"A large overhaul of the restartable sequences and CID management:
The recent enablement of RSEQ in glibc resulted in regressions which
are caused by the related overhead. It turned out that the decision to
invoke the exit to user work was not really a decision. More or less
each context switch caused that. There is a long list of small issues
which sums up nicely and results in a 3-4% regression in I/O
benchmarks.
The other detail which caused issues due to extra work in context
switch and task migration is the CID (memory context ID) management.
It also requires to use a task work to consolidate the CID space,
which is executed in the context of an arbitrary task and results in
sporadic uncontrolled exit latencies.
The rewrite addresses this by:
- Removing deprecated and long unsupported functionality
- Moving the related data into dedicated data structures which are
optimized for fast path processing.
- Caching values so actual decisions can be made
- Replacing the current implementation with a optimized inlined
variant.
- Separating fast and slow path for architectures which use the
generic entry code, so that only fault and error handling goes into
the TIF_NOTIFY_RESUME handler.
- Rewriting the CID management so that it becomes mostly invisible in
the context switch path. That moves the work of switching modes
into the fork/exit path, which is a reasonable tradeoff. That work
is only required when a process creates more threads than the
cpuset it is allowed to run on or when enough threads exit after
that. An artificial thread pool benchmarks which triggers this did
not degrade, it actually improved significantly.
The main effect in migration heavy scenarios is that runqueue lock
held time and therefore contention goes down significantly"

This patch adds a near[1] complete YNL specification for WireGuard,
documenting the protocol in a machine-readable format, rather than
comments in wireguard.h, and eases usage from C and non-C programming
languages alike.
The generated C library will be featured in a later patch, so in
this patch I will use the in-kernel python client for examples.
This makes the documentation in the UAPI header redundant, it is
therefore removed. The in-line documentation in the spec is based
on the existing comment in wireguard.h, and once released it will
be available in the kernel documentation at:
https://docs.kernel.org/netlink/specs/wireguard.html
(until then run: make htmldocs)
Generate wireguard.rst from this spec:
$ make -C tools/net/ynl/generated/ wireguard.rst
Query wireguard interface through pyynl:
$ sudo ./tools/net/ynl/pyynl/cli.py --family wireguard \
--dump get-device \
--json '{"ifindex":3}'
[{'fwmark': 0,
'ifindex': 3,
'ifname': 'wg-test',
'listen-port': 54318,
'peers': [{0: {'allowedips': [{0: {'cidr-mask': 0,
'family': 2,
'ipaddr': '0.0.0.0'}},
{0: {'cidr-mask': 0,
'family': 10,
'ipaddr': '::'}}],
'endpoint': b'[...]',
'last-handshake-time': {'nsec': 42, 'sec': 42},
'persistent-keepalive-interval': 42,
'preshared-key': '[...]',
'protocol-version': 1,
'public-key': '[...]',
'rx-bytes': 42,
'tx-bytes': 42}}],
'private-key': '[...]',
'public-key': '[...]'}]
Add another allowed IP prefix:
$ sudo ./tools/net/ynl/pyynl/cli.py --family wireguard \
--do set-device --json '{"ifindex":3,"peers":[
{"public-key":"6a df b1 83 a4 ..","allowedips":[
{"cidr-mask":0,"family":10,"ipaddr":"::"}]}]}'
[1] As can be seen above, the "endpoint" is only dumped as binary data,
as it can't be fully described in YNL. It's either a struct
sockaddr_in or struct sockaddr_in6 depending on the attribute length.

Pull directory locking updates from Christian Brauner:
"This contains the work to add centralized APIs for directory locking
operations.
This series is part of a larger effort to change directory operation
locking to allow multiple concurrent operations in a directory. The
ultimate goal is to lock the target dentry(s) rather than the whole
parent directory.
To help with changing the locking protocol, this series centralizes
locking and lookup in new helper functions. The helpers establish a
pattern where it is the dentry that is being locked and unlocked
(currently the lock is held on dentry->d_parent->d_inode, but that can
change in the future).
This also changes vfs_mkdir() to unlock the parent on failure, as well
as dput()ing the dentry. This allows end_creating() to only require
the target dentry (which may be IS_ERR() after vfs_mkdir()), not the
parent"

Pull vfs inode updates from Christian Brauner:
"Features:
- Hide inode->i_state behind accessors. Open-coded accesses prevent
asserting they are done correctly. One obvious aspect is locking,
but significantly more can be checked. For example it can be
detected when the code is clearing flags which are already missing,
or is setting flags when it is illegal (e.g., I_FREEING when
->i_count > 0)
- Provide accessors for ->i_state, converts all filesystems using
coccinelle and manual conversions (btrfs, ceph, smb, f2fs, gfs2,
overlayfs, nilfs2, xfs), and makes plain ->i_state access fail to
compile
- Rework I_NEW handling to operate without fences, simplifying the
code after the accessor infrastructure is in place
Cleanups:
- Move wait_on_inode() from writeback.h to fs.h
- Spell out fenced ->i_state accesses with explicit smp_wmb/smp_rmb
for clarity
- Cosmetic fixes to LRU handling
- Push list presence check into inode_io_list_del()

Pull iomap updates from Christian Brauner:
"FUSE iomap Support for Buffered Reads:
This adds iomap support for FUSE buffered reads and readahead. This
enables granular uptodate tracking with large folios so only
non-uptodate portions need to be read. Also fixes a race condition
with large folios + writeback cache that could cause data corruption
on partial writes followed by reads.
- Refactored iomap read/readahead bio logic into helpers
- Added caller-provided callbacks for read operations
- Moved buffered IO bio logic into new file
- FUSE now uses iomap for read_folio and readahead
Zero Range Folio Batch Support:
Add folio batch support for iomap_zero_range() to handle dirty
folios over unwritten mappings. Fix raciness issues where dirty data
could be lost during zero range operations.
- filemap_get_folios_tag_range() helper for dirty folio lookup
- Optional zero range dirty folio processing
- XFS fills dirty folios on zero range of unwritten mappings
- Removed old partial EOF zeroing optimization
DIO Write Completions from Interrupt Context:
Restore pre-iomap behavior where pure overwrite completions run
inline rather than being deferred to workqueue. Reduces context
switches for high-performance workloads like ScyllaDB.
- Removed unused IOCB_DIO_CALLER_COMP code
- Error completions always run in user context (fixes zonefs)
- Reworked REQ_FUA selection logic
- Inverted IOMAP_DIO_INLINE_COMP to IOMAP_DIO_OFFLOAD_COMP
Buffered IO Cleanups:
Some performance and code clarity improvements:
- Replace manual bitmap scanning with find_next_bit()
- Simplify read skip logic for writes
- Optimize pending async writeback accounting
- Better variable naming
- Documentation for iomap_finish_folio_write() requirements
Misaligned Vectors for Zoned XFS:
Enables sub-block aligned vectors in XFS always-COW mode for zoned
devices via new IOMAP_DIO_FSBLOCK_ALIGNED flag.

interrupt-controller requirement

not used as an interrupt controller.

The driver commit 7687a12153d3 ("drm/vc4: hvs: Add support for BCM2712

the BCM7212.
Update the schema to correct the interrupt requirements for BCM2712.
(Requirements for BCM2711 should be unchanged).

The current set of DMI board IDs from the fixes branch is required to
reorder them in the for-next branch.

The makefile logic to detect if rust is enabled is not working
the way it was expected: instead of using the current setup
for CONFIG_RUST, it uses a cached version from a previous build.
The root cause is that the current logic inside docs/Makefile
uses a cached version of CONFIG_RUST, from the last time a non
documentation target was executed. That's perfectly fine for
Sphinx build, as it doesn't need to read or depend on any
CONFIG_*.
So, instead of relying at the cache, move the logic to the
wrapper script and let it check the current content of .config,
to verify if CONFIG_RUST was selected.

The paragraph mentions only removal of Tested-by and Reviewed-by tags as
action needing mentioning in patch changelog, so some developers treat
it too literally. Acks, as a weaker form of review/approval, should
rarely be removed, but if that happens it should be explained as well.

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.
Aside from these main changes, there is the usual load of fixes and API
updates.

When developing the gamezone WMI drivers, "extreme mode" was matched to
the performance platform profile and "performance" was matched to the
balanced-performance platform profile, but only if extreme mode was
fully supported; otherwise performance was matched to the "performance"
platform profile. This has led to quite a bit of confusion with users
not understanding why the LED color indicating the platform profile
doesn't match their expectations.
To solve this, replace the confusing convention by using the new
max-power profile to represent "extreme mode". While add it, update the
documentation to reflect the expected LED colors in each operating mode.

Introduce a generic infrastructure for tracking recoverable hardware
errors (HW errors that are visible to the OS but does not cause a panic)
and record them for vmcore consumption. This aids post-mortem crash
analysis tools by preserving a count and timestamp for the last occurrence
of such errors. On the other side, correctable errors, which the OS
typically remains unaware of because the underlying hardware handles them
transparently, are less relevant for crash dump and therefore are NOT
tracked in this infrastructure.
Add centralized logging for sources of recoverable hardware errors based
on the subsystem it has been notified.
hwerror_data is write-only at kernel runtime, and it is meant to be read
from vmcore using tools like crash/drgn. For example, this is how it
looks like when opening the crashdump from drgn.
>>> prog['hwerror_data']
(struct hwerror_info[1]){
{
.count = (int)844,
.timestamp = (time64_t)1752852018,
},
...
This helps fleet operators quickly triage whether a crash may be
influenced by hardware recoverable errors (which executes a uncommon code
path in the kernel), especially when recoverable errors occurred shortly
before a panic, such as the bug fixed by commit ee62ce7a1d90 ("page_pool:
Track DMA-mapped pages and unmap them when destroying the pool")
This is not intended to replace full hardware diagnostics but provides a
fast way to correlate hardware events with kernel panics quickly.
Rare machine check exceptions—like those indicated by mce_flags.p5 or
mce_flags.winchip—are not accounted for in this method, as they fall
outside the intended usage scope for this feature's user base.

Patch series "Live Update Orchestrator", v8.
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
The other series that use LUO, are VFIO [1], IOMMU [2], and PCI [3]
preservations.
Github repo of this series [4].
The core of LUO is a framework for managing the lifecycle of preserved
resources through a userspace-driven interface. Key features include:
- Session Management
Userspace agent (i.e. luod [5]) creates named sessions, each
represented by a file descriptor (via centralized agent that controls
/dev/liveupdate). The lifecycle of all preserved resources within a
session is tied to this FD, ensuring automatic kernel cleanup if the
controlling userspace agent crashes or exits unexpectedly.
- File Preservation
A handler-based framework allows specific file types (demonstrated
here with memfd) to be preserved. Handlers manage the serialization,
restoration, and lifecycle of their specific file types.
- File-Lifecycle-Bound State
A new mechanism for managing shared global state whose lifecycle is
tied to the preservation of one or more files. This is crucial for
subsystems like IOMMU or HugeTLB, where multiple file descriptors may
depend on a single, shared underlying resource that must be preserved
only once.
- KHO Integration
LUO drives the Kexec Handover framework programmatically to pass its
serialized metadata to the next kernel. The LUO state is finalized and
added to the kexec image just before the reboot is triggered. In the
future this step will also be removed once stateless KHO is
merged [6].
- Userspace Interface
Control is provided via ioctl commands on /dev/liveupdate for creating
and retrieving sessions, as well as on session file descriptors for
managing individual files.
- Testing
The series includes a set of selftests, including userspace API
validation, kexec-based lifecycle tests for various session and file
scenarios, and a new in-kernel test module to validate the FLB logic.
Introduce LUO, a mechanism intended to facilitate kernel updates while
keeping designated devices operational across the transition (e.g., via
kexec). The primary use case is updating hypervisors with minimal
disruption to running virtual machines. For userspace side of hypervisor
update we have copyless migration. LUO is for updating the kernel.
This initial patch lays the groundwork for the LUO subsystem.
Further functionality, including the implementation of state transition
logic, integration with KHO, and hooks for subsystems and file
descriptors, will be added in subsequent patches.
Create a character device at /dev/liveupdate.
A new uAPI header, <uapi/linux/liveupdate.h>, will define the necessary
structures. The magic number for IOCTL is registered in
Documentation/userspace-api/ioctl/ioctl-number.rst.

RISC-V Devicetrees for v6.19
MAINTAINERS:
There's some re-jigging of things to reduce duplication, by moving me
into the StarFive entry and my tree into the Microchip one. The
other platforms that I look after (SiFive and Canaan) are marked as Odd
Fixes to better represent their status. Nothing functionally changes.
Microchip:
Add adc and mmc nodes for the Beagle-V Fire.
SiFive:
Add pwm fans to the unmatched board.
StarFive:
Add the Orange PI RV board, another VisionFive 2 derived SBC. This
required moving a mmc related nodes out of the common file, into
<board>.dts. Yet more things moved out of the common file when the
VisionFive 2 Lite boards were added, which use the JH7110S SoC instead of
the JH7110. The difference here between SoCs is just temperature and
frequency ranges, but the boards differ enough that the pool of common
nodes decreases a little further. There's an eMMC and an SD variant
here, that are different SKUs, bringing the total new StarFive boards to
three.

debugfs access modes were added in Linux 5.10 (Dec 2020) [1], but the
no-mount mode has behaved effectively the same as the off mode since
Linux 5.12 (Apr 2021) [2]. The only difference is the specific error
code returned by the debugfs_create_* functions, which is -ENOENT in
no-mount mode and -EPERM in off mode.
Given that no-mount hasn't worked for several years with no complaints,
just remove it.

The fix commit converted several IPv4 address attributes from binary
to u32, but forgot to specify byte-order: big-endian. Without this,
YNL tools display IPv4 addresses incorrectly due to host-endian
interpretation.
Add the missing byte-order: big-endian to all affected u32 IPv4
address fields to ensure correct parsing and display.

Expose the current system-defined list of housekeeping CPUs in a new
sysfs file: /sys/devices/system/cpu/housekeeping.
This provides userspace performance tuning tools and resource managers
with a canonical, reliable method to accurately identify the cores
responsible for essential kernel maintenance workloads (RCU, timer
callbacks, and unbound workqueues). Currently, tooling must manually
calculate the housekeeping set by parsing complex kernel boot parameters
(like isolcpus= and nohz_full=) and system topology, which is prone to
error. This dedicated file simplifies the configuration of low-latency
workloads.

This patch introduces a new UIO driver, uio_pci_generic_sva, which
extends the functionality of uio_pci_generic by adding support for
Shared Virtual Addressing (SVA) when IOMMU is enabled in the system.
The key enhancement allows PCI devices to directly use user-space virtual
addresses for DMA operations, eliminating the need for bounce buffers or
explicit IOVA mapping. This is achieved by leveraging the kernel's IOMMU-SVA
subsystem, including process address space attachment, page fault handling,
and shared context management between CPU and device.
With this driver, userspace applications can perform zero-copy DMA using
native pointers:
void *addr = malloc(N);
set_dma_addr((uint64_t)addr); // Passing user VA directly
start_dma();
The device can now access 'addr' through the IOMMU's PASID-based translation,
provided that the underlying IOMMU hardware (e.g., Intel VT-d 3.1+, AMD-Vi,
ARM SMMU, RISCV IOMMU) and platform support SVA.
Dependencies:
- CONFIG_IOMMU_SVA must be enabled.
- The platform must support PRI (Page Request Interface) and PASID.
- Device drivers/userspace must handle page faults if demand-paging is used.
The implementation reuses core logic from uio_pci_generic.c while adding
PASID setting, and integration with the IOMMU SVA APIs.
Also, add a read-only sysfs attribute 'pasid' to expose the Process Address
Space ID assigned by IOMMU driver when binding an SVA-enabled device.
For details, refer to the ABI documentation for uio_pci_sva driver sysfs attribute
(Documentation/ABI/testing/sysfs-driver-uio_pci_sva-pasid).
