If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then
it results in an out of bounds access.
The code checks for invalid values, but doesn't set the error code. Return
-EINVAL in that case, instead of returning success.

setup_percpu_irq() was forgotten when the percpu_devid infrastructure was
updated to deal with CPU affinities.
In order to keep ignoring users of this legacy API, provide sensible
defaults by setting the affinity to cpu_online_mask if none was provided by
the caller.

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
- fix to not account invalid blocks in get_left_section_blocks()
- revert summary entry count from 2048 to 512 in 16kb block support
- fix to 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()
- fix to propagate error from f2fs_enable_checkpoint()
- invalidate dentry cache on failed whiteout creation
- fix to avoid updating compression context during writeback
- fix to avoid updating zero-sized extent in extent cache
- fix to avoid potential deadlock

either later fixes, or cleanups that don't make sense to defer. This

- Fix for a recent regression in io-wq worker creation
- Tracing cleanup
- Use READ_ONCE/WRITE_ONCE consistently for ring mapped kbufs. Mostly
for documentation purposes, indicating that they are shared with
userspace
- Fix for POLL_ADD losing a completion, if the request is updated and
now is triggerable - eg, if POLLIN is set with the updated, and the
polled file is readable
- In conjunction with the above fix, also unify how poll wait queue
entries are deleted with the head update. We had 3 different spots
doing both the list deletion and head write, with one of them
nicely documented. Abstract that into a helper and use it
consistently
- Small series from Joanne fixing an issue with buffer cloning, and
cleaning up the arg validation"

incrementally add clks to their SoC drivers, causing them to show up higher in

plug error paths or fix typos.

The for_each_child_of_node() macro automatically manages device node
reference counts during normal iteration. However, when breaking out
of the loop early with return, the current iteration's node is not
automatically released, leading to a reference count leak.
Fix this by adding of_node_put(child) before returning from the loop
when emc2305_set_single_tz() fails.
This issue could lead to memory leaks over multiple probe cycles.

The macro FAN_FROM_REG evaluates its arguments multiple times. When used
in lockless contexts involving shared driver data, this leads to
Time-of-Check to Time-of-Use (TOCTOU) race conditions, potentially
causing divide-by-zero errors.
Convert the macro to a static function. This guarantees that arguments
are evaluated only once (pass-by-value), preventing the race
conditions.
Additionally, in store_fan_div, move the calculation of the minimum
limit inside the update lock. This ensures that the read-modify-write
sequence operates on consistent data.
Adhere to the principle of minimal changes by only converting macros
that evaluate arguments multiple times and are used in lockless
contexts.

From users point of view, perf list will provide richer
information about hardware events like the following.

[Retired branch instructions [This event is an alias of branches]. Unit: cpu]
branch-misses
[Mispredicted branch instructions. Unit: cpu]
branches
[Retired branch instructions [This event is an alias of branch-instructions]. Unit: cpu]
bus-cycles
[Bus cycles,which can be different from total cycles. Unit: cpu]
cache-misses
[Cache misses. Usually this indicates Last Level Cache misses; this is intended to be used in conjunction with the
PERF_COUNT_HW_CACHE_REFERENCES event to calculate cache miss rates. Unit: cpu]
cache-references
[Cache accesses. Usually this indicates Last Level Cache accesses but this may vary depending on your CPU. This may include
prefetches and coherency messages; again this depends on the design of your CPU. Unit: cpu]
cpu-cycles

Deferred unwinding support
--------------------------
With the kernel support [1], perf can use deferred callchains for
userspace stack trace with frame pointers like below:
$ perf record --call-graph fp,defer ...
This will be transparent to users when it comes to other commands like
perf report and perf script. They will merge the deferred callchains to
the previous samples as if they were collected together.
[1] https://git.kernel.org/torvalds/c/c69993ecdd4dfde2b7da08b022052a33b203da07
ARM SPE updates
---------------
* Extensive enhancements to support various kinds of memory operations
including GCS, MTE allocation tags, memcpy/memset, register access,
and SIMD operations.
* Add inverted data source filter (inv_data_src_filter) support to
exclude certain data sources.
* Improve documentation.
Vendor event updates
--------------------
* Intel: Updated event files for Sierra Forest, Panther Lake, Meteor Lake,
Lunar Lake, Granite Rapids, and others.
* Arm64: Added metrics for i.MX94 DDR PMU and Cortex-A720AE definitions.
* RISC-V: Added JSON support for T-HEAD C920V2.
Misc
----
* Improve pointer tracking in data type profiling. It'd give better
output when the variable is using container_of() to convert type.
* Annotation support for perf c2c report in TUI. Press 'a' key to
enter annotation view from cacheline browser window. This will show
which instruction is causing the cacheline contention.
* Lots of fixes and test coverage improvements!

Unify all event and metric descriptions in JSON format. Now event
parsing and handling is greatly simplified by that.
From users point of view, perf list will provide richer information
about hardware events like the following.
$ perf list hw

branches
[Retired branch instructions [This event is an alias of branch-instructions]. Unit: cpu]

PERF_COUNT_HW_CACHE_REFERENCES event to calculate cache miss rates. Unit: cpu]

Here is the big set of staging driver updates for 6.19-rc1. Only thing
"major" in here is that two subsystems, gpib and vc04 have moved out of
the staging tree into the "real" portion of the kernel, which is great
to see. Other than that, the rest of the changes are just tiny coding
style cleanups, nothing earth-shattering.

Commit 2f26f58df0 ("ocfs2: annotate flexible array members with
__counted_by_le()") started annotating the flexible arrays used by
ocfs2, and now gcc complains about ocfs2_reflink_xattr_header():
In function ‘fortify_memset_chk’,
inlined from ‘ocfs2_reflink_xattr_header’ at fs/ocfs2/xattr.c:6365:5:
include/linux/fortify-string.h:480:25: error: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
and it looks like the complaint is valid - even if the actual error
message is somewhat confusing.
The 'last' pointer points to past the end of the counted flex array, but
is used as an actual 'last' entry rather than a 'one-past-last'.
It looks like the code copied and cleared an extra entry (which is
likely harmless in practice), but I don't know ocfs2 at all. Because
it's also possible that the counted-by annotations are off-by-one, and
so this needs checking by somebody who actually knows ocfs2.
But in the meantime this fixes the build error, and certainly _looks_
sane.

- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
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.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

- Fix accounting of stop_count in file release
On opening the trace file, if "pause-on-trace" option is set, it will
increment the stop_count. On file release, it checks if stop_count is set,
and if so it decrements it. Since this code was originally written, the
stop_count can be incremented by other use cases. This makes just checking
the stop_count not enough to know if it should be decremented.
Add a new iterator flag called "PAUSE" and have it set if the open
disables tracing and only decrement the stop_count if that flag is set on
close.
- Remove length field in trace_seq_printf() of print_synth_event()
When printing the synthetic event that has a static length array field,
the vsprintf() of the trace_seq_printf() triggered a "(efault)" in the
output. That's because the print_fmt replaced the "%.*s" with "%s" causing
the arguments to be off.
- Fix a bunch of typos

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 in this pull request 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

added a `pub(crate)` import in the same "block" as the `pub` one,
without running `rustfmt`, which would sort them differently.
Instead of running `rustfmt` as-is, add a newline to keep the import
"blocks" with different visibilities separate.

Rust module parameter support:
- Add Rust module parameter support, enabling Rust kernel modules to declare
and use module parameters. The rust_minimal sample module demonstrates this,
and the rust null block driver will be the first to use it in the next cycle.
This also adds the Rust module files under the modules subsystem as agreed
between the Rust and modules maintainers.
Hardening:
- Add compile-time check for embedded NUL characters in MODULE_*() macros. This
module metadata was once used (and maybe still) to bypass license enforcement
(LWN article [1] from 2003). This change required a sparse fix [2] which you
reviewed.
MAINTAINERS:
- Add Aaron Tomlin as reviewer for the Modules subsystem.
The changes have been in linux-next for 4 weeks. Recent 0day reports for UM [3]
and arm64 [4] builds were not reproducible and traced to a buggy bindgen version
combined with unreleased clang-22 in 0day. The Rust team has reported this to
0day.
As discussed previously, we rotate module maintainership among co-maintainers
every 6 months. Sami Tolvanen is next in line and will send the next pull
request. As a reminder, Luis has already announced [5] he will gradually step
away as maintainer.
