dw_i3c_master_daa() derives the number of newly assigned dynamic
addresses from cmd->rx_len, the ISR sets it to the number of address
slots ENTDAA left unassigned. It starts out as zero, which already
means "every address was assigned", so a timed out transfer leaves
that value in place and it gets used as a result.
If there's no client connected, the addr assign cmd times out, then
the driver calls i3c_master_add_i3c_dev_locked() to add devices that
are not there, each costing about 1s, thus adds non necessary boot
time up to (maxdev * 1)s.
Start from maxdevs instead: no address is assigned before ENTDAA runs,
and the existing rx_count >= maxdevs check then reports an empty bus.

Pull ARM SoC platform updates from Arnd Bergmann:
"The 32-bit Arm platforms are a bit more interesting this time: I
refreshed an earlier series to mark code as deprecated that does have
the tendency of getting in the way of cleanups and new features but
has close to zero users. Among these are:
- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and
Marvell. The remaining six board files are for TI OMAP1 and Samsung
s3c64xx chips and all still have known users.
- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.
- be8, be32, oabi and iwmmxt userspace binaries, which were mostly
associated with the platforms now scheduled for removal and are
increasingly problematic to support with modern toolchains.
Nothing is actually removed at this point, to ensure that any
remaining users continue to have the 7.3-LTS for a while longer.
Patches for removal are currently being tested.
Other updates include a continued work to convert GPIO number based
interfaces to descriptors, a patch to restore little-endian mode on
the one Arm platform (ixp4xx) that only worked in big-endian mode
recently, and some minor cleanups and bugfixes"

Pull SoC driver updates from Arnd Bergmann:
"The SoC driver changes once more consist of many small fixes and
cleanups, that are to a large part the result of automated testing.
On platform specific drivers, this includes SoC specific code for
xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung,
rockchip, renesas, ixp4xx. In firmware drivers, we see a similar
picture for SCMI and qcomtee.
Aside from these, we see actual new hardware support in a few areas:
- The Apple platform gets a new driver for low power states
- Updates to Qualcomm platform drivers add several new hardware
specific features and additional SoCs.
- Amlogic SoC support for A1 and T7 is added
- The Mediatek MMSYS driver is refactored as a cleanup"

Pull SoC devicetree updates from Arnd Bergmann:
"There are two new mystery SoCs with very little public information
about them so far, Qualcomm's Cortex-A78C based "Shikra" and Altera's
Cortex-A720 based Agilex72 SOCFPGA.
We have also gained support for a couple of SoCs from the 2023/2024
timeframe that have been in the making for a while:
- The Apple platform gains support for M3 Pro, Max and Ultra SoC,
following the basic M3 support from 7.2.
- Samsung Exynos 1580 is a high-end mobile phone SoC from 2024
- Canaan K230 is a RISC-V based 64-bit AI SoC, based on the earlier
K210 chip
- Sophgo SG2000 is a mixed Arm/RISC-V chip that was already supported
using the Arm core but is now also added for RISC-V along with
several other variants of the cv18xx series
In terms of newly added machines we have reference platforms for all
the chips above, plus
- Only four 32-bit Arm boards: two older phones and two older
industrial/embedded boards; using Allwinner, Qualcomm and Rockchip
SoCs
- Three laptops und three phones using Qualcomm SoCs
- Ten 64-bit Rockchips based single-board computers, along with one
NAS box and a game console.
- Seven industrial/embedded boards and modules using NXP i.MX8/9
SoCs.
- A Lenovo desktop box based on NVIDIA Jetson Xavier NX
- A few more single-board computers based on Allwinnner A133,
Spacemit K1 and TI AM62.
As usual, there is a constant stream of minor cleanups and fixes
towards addressing the 'dt-check-style --mode strict' warnings, and
everyone is expected to address those warnings for new submissions
now"

Pull VDSO updates from Thomas Gleixner:
- Consolidate the VDSO datastore further and provide support for
mlock_all() and prefaulting.
- Provide 32-bit legacy time related functionality only if

but architecture code still exposes the legacy functionality even
disabled.
Clean this up by adding the missing guards and validating at build
time that the VDSO is legacy free if disabled.

Per PCIe r7.0 sec 6.2.4.3, certain Non-Fatal Errors may be signaled using
ERR_COR instead of ERR_NONFATAL. These "Advisory Non-Fatal Errors" are
listed in sec 6.2.7 and explained in detail in sec 6.2.3.2.4.
Advisory Non-Fatal Errors set bits in the Uncorrectable Error Status
Register as well as one bit in the Correctable Error Status Register
(Advisory Non-Fatal Error Status, bit 13). The latter is masked by
default, hence these errors are currently not signaled at all (except on
non-compliant products which choose to unmask the bit).
Unmask Advisory Non-Fatal Errors on device enumeration.
Some Non-Fatal Errors are always Advisory, others may be Advisory at the
discretion of the detecting agent. If multiple errors occur, the agent
may qualify a portion as non-Advisory and signal ERR_NONFATAL in addition
to ERR_COR. In this case, there's no way to determine which Non-Fatal
Error was Advisory. Assume none is to ensure that the Uncorrectable Error
code path is taken to recover from the errors.
Introduce aer_compute_anfe_status() to compute Advisory Non-Fatal Error
bits from AER registers, based on this policy. Use it for Firmware First
error handling in pci_print_aer(), which receives an AER register dump
from the platform (UEFI r2.11 sec N.2.7).
Introduce aer_get_anfe_status() to read AER registers from a device and
feed them to aer_compute_anfe_status(). Use it for native error handling
in aer_get_device_error_info(), which gathers registers from the device
and caches the computed Advisory Non-Fatal Error bits in a new anfe_status
field in struct aer_err_info.
Regardless whether error handling is native or Firmware First, the AER
driver needs to increment error counters, signal a trace event and log
each error. When Advisory Non-Fatal Errors occur, these steps must be
performed for Correctable Errors and for Uncorrectable Errors. Achieve
this through a recursive invocation of aer_print_error() (for native error
handling) and pci_print_aer() (for Firmware First error handling). The
recursive invocation reports the (Advisory) Uncorrectable Errors after
reporting the Correctable Errors.
Note that the First Error Pointer and TLP Prefix Log is only meaningful
for Uncorrectable Errors, but when Advisory Non-Fatal Errors occur,
aer_get_device_error_info() has to populate the first_error and
tlp_header_valid fields in struct aer_err_info for a Correctable Error.
Avoid incorrectly logging those fields for Correctable Errors by amending
__aer_print_error() and aer_print_error() with conditionals.
Sample log output for an Advisory Unsupported Request Error:
pcieport 0001:00:00.4: AER: Multiple Correctable Error messages received, first one from 0001:0e:00.0

- Remove redundant dev_err() and dev_err_probe() invocations in various
drivers as that error logging has been moved to devm_request_*_irq().
- Support dynamic MSI-X allocations in the GIC-V3-ITS MSI parent domain
driver. That's important for VFIO pass through devices to avoid
reinitialization of the MSI-X space when extending the vector range.
Such a reinitialization can result is lost interrupts and stale
devices.

In PIO mode initialization, STAT_IBI_STATUS_THLD was missing from
pio->enabled_irqs. As a result, the host controller interrupt signal for
IBI threshold was never enabled when transfer starts, preventing IBI
status descriptors from being properly processed in PIO mode.
Include STAT_IBI_STATUS_THLD in pio->enabled_irqs so that the IBI
threshold interrupt is activated alongside error interrupts upon the first
transfer.

git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Warn when using 'bindgen' < 0.72.1 with 'libclang' >= 22, since
that combination may fail to build. It includes a probe for the bug
in case 'bindgen' happens to be patched, and tests
In parallel, Nathan updated the instructions for the kernel.org
LLVM+Rust toolchains so that the latest version of 'bindgen' is
installed, which should avoid some of these situations
- Support testing 'rust_is_available.sh' with 'bash' as '/bin/sh'
- Fix an objtool warning by adding one more 'noreturn' function for
Rust 1.99.0 (expected 2026-10-01)
- Fix build error in the 'rusttest' target due to ambiguity when the
'rustc-dev' component is installed, which was uncovered by the work
to support Rust's GCC backend ('rustc_codegen_gcc')
- Fix future Clang warnings in the upcoming powerpc support due to
macro redefinitions in the UAPI helper header by including the
arch-aware 'ioctl.h' header
'kernel' crate:
- Rework module ownership support:
- Move the module-related types into a new 'module' module and
make the 'THIS_MODULE' pointer a constant of 'ModuleMetadata'
so that modules can provide the pointer in const contexts, and
add a 'this_module' 'const fn' to retrieve it
This was enabled by upstream Rust's work on the 'const_mut_refs'
and 'const_refs_to_static' features which were stabilized back
in Rust 1.83.0
- Teach '#[vtable]' to associate implementations with their
owning module, defaulting to the local one, including fallbacks
for doctests, uses within the 'kernel' crate (like upcoming
KUnit '#[test]'s for DRM) and 'rusttest'
- Set 'fops.owner' from the module pointer for DRM and
miscdevice
- Migrate Rust Binder and configfs away from the old
'THIS_MODULE' 'static' and finally remove it from the 'module!'
macro
- 'num' module:
- Add the new 'casts' module for lossless integer conversions
Rust's 'core' library's 'From' implementations do not cover
conversions that are not portable or future-proof. However, the
kernel supports a narrower set of architectures, which makes it
helpful to provide more infallible conversions, instead of
having developers use 'as' casts, which carry the risk of
silently losing data
This goes along with previous work we did to avoid casts in
Rust kernel code since they are more powerful than needed
Thus, provide safe 'const' conversion functions (e.g.
'usize_as_u64' and 'u64_into_u8'), as well as the
'FromSafeCast' and 'IntoSafeCast' extension traits that provide
conversions that are known to be lossless in the kernel, and an
'arch' submodule defining conversions that are known to be
lossless on particular architectures (e.g. 64-bit platforms).
For instance:
// Conversion in const context.
const USIZED_CONST: usize = u8_as_usize(255u8);
// Non-const conversions.
let a = u64::from_safe_cast(4096usize);
let b: u64 = 4096usize.into_safe_cast();
- Add 'Bounded::shr_exact' method in the vein of 'try_shrink'
which shifts a bounded right only if it loses no set bits
- Fix unsoundness issue in the 'Bounded::shr' method by
rejecting, at compile-time, shifts of at least the type's bit
width
- 'fmt' module:
- Route '{:p}' raw pointer formatting through the kernel's hashed
'%p' format to prevent address leaks, including support for
width and padding. Include tests for both 'no_hash_pointers'
case and the default (hashed) one
- Fix the '{:p}' forwarding implementation, which could print the
address of a temporary stack variable
- 'time' module:
- Make 'Delta' generic over its time unit, with a default unit of
nanoseconds ('Nsec'), preserving the existing behavior. Then,
add a 'Jiffy' time unit
- Add the 'Delta::as_millis_ceil()' method
- Fix 'as_micros_ceil()' rounding near 'i64::MAX', which could
yield a result one microsecond too small
- 'sync' module:
- Implement 'ForeignOwnable' for 'ARef<T>', allowing C code to
own an 'ARef<T>'
- Add a safe abstraction for 'rcu_barrier()'
- 'error' module: add all of the remaining error codes, except the
deprecated compatibility aliases
- 'bug' module:
- Fix build error on UML in 'warn_on!' for callers from within
the 'kernel' crate
- Fix future 'dead_code' warning on arm and loongarch64 and under
'CONFIG_BUG=n' in 'warn_on!', which would trigger with the
upcoming SRCU abstractions
- Fix future build error in 'rusttest' on cross-compilation
cases, which would trigger when 'warn_on!' has callers inside
the 'kernel' crate
- 'bitfield' module: fix build error for the upcoming support for
Rust's GCC backend ('rustc_codegen_gcc') by always inlining a
couple conversions used in tests
'pin-init' crate:
- User-visible changes:
- Merge the '__pinned_init' and '__init' methods and make 'Init'
a marker trait
- Introduce public APIs 'raw_init' and 'raw_try_init' to prevent
users from needing to invoke the internal '__pinned_init' and
'__init' methods
- Emit errors for duplicate '#[pin]' attributes
- Link 'Zeroable::zeroed' and 'pin_init::zeroed' in documentation
- Other changes:
- Fix unwind safety issues
- Clean up lint 'allow' and 'expect's
- Overhaul '#[cfg]' handling to pave the way for tuple structs
and self-referential structs
- Mark many functions as '#[inline]' for better codegen with '-C
opt-level=s' ('CC_OPTIMIZE_FOR_SIZE')
'MAINTAINERS':
- Update 'MODULE SUPPORT' to cover the new 'module' module
And some other fixes, cleanups and improvements"

When hardware GRO (SHAMPO) coalesces a small IPv4/TCP segment that was
padded up to the 60-byte minimum Ethernet frame, the trailing padding is
folded into the merged payload causing padding to be delivered
to the user as payload.
Detecting and reproducing the issue: the selftest
tools/testing/selftests/drivers/net/gro.py subtest
hw_ipv4_data_lrg_1byte sends {100, 1} expecting to receive {101}.
In current code, it receives {106} (100 + 1 payload + 5 pad) instead.
This patch avoids giving the user padding as payload by simply not
coalescing small packets (which fails the subtest; the same approach
and behavior as sw gro). This gains code simplicity at the cost of
more computation (passing an extra skb up the stack) for small packets
that could be coalesced.
The threshold is chosen as ETH_ZLEN + 2 * VLAN_HLEN. This is the largest
frame that may still contain minimum-frame padding (+ 2 VLAN tags), so
anything larger is safe to consider for coalesce. (We do not include
ETH_FCS_LEN in that threshold computation as netdev_fix_features()
drops NETIF_F_GRO_HW whenever NETIF_F_RXFCS is set, so retained FCS
can't reach this path.)

Pull memblock updates from Mike Rapoport:
"Non-urgent fixes:
- Fix calculation of node_spanned_pages when running
with 'kernelcore=mirror'
- Properly handle failure to allocate per_cpu_nodestats
in free_area_init_core_hotplug()
- Fix deferred initialization of the memory map for
configurations where node's RAM end is not aligned
on PAGES_PER_SECTION
Cleanups:
- Remove redundant pageblock_align() call in free_unused_memmap()
- Remove unnecessary invalid range checks in users of memblock
iterators. Some users of for_each_mem_range() and
for_each_mem_pfn_range() verify that start < end for each range.
This is redundant because memblock iterators guarantee to never
return an invalid range
- Stop overlapping zones with 'kernelcore=mirror' and align behaviour
of 'kernelcore=mirror' with other variants of kernelcore and
movablecore
- Remove redundant updates of numa_nodes_parsed mask in the callers
of numa_add_memblk(), the latter always updates the mask anyway
- Remove unnecessary initialization of pgdat->per_cpu_nodestats to
NULL, the variable is reset to the actual value a few lines below"

Add PTP clock support for the ZL3073x DPLL driver. A PTP clock device
is registered for each DPLL channel regardless of the initial channel
state, providing gettimex64, settime64, adjtime, adjfine, adjphase
and getmaxphase callbacks.
Callback availability depends on the current channel state:
- adjfine: when NCO pin is connected (returns -EOPNOTSUPP otherwise)
- adjphase: available when tracking a reference, uses TIE write
- adjtime: always available and uses
* phase step for sub-second deltas when NCO pin is connected
* TIE write when tracking a reference
* plain ToD read-modify-write otherwise
- gettime/settime: always available
The adjtime callback splits multi-second adjustments into a ToD
read-modify-write for the seconds part and a sub-second mechanism
(phase step or TIE write) for the remainder. On partial failure
where seconds were already committed, success is returned to
prevent the PTP servo from retrying and applying seconds again.
All PTP callbacks are serialized by the existing per-DPLL zldpll->lock
mutex, which is also used by DPLL pin and device callbacks.

Add low-level DPLL channel operations for ToD read/write/adjust,
output phase step, delta frequency offset write and TIE (Time
Interval Error) write. These serve as building blocks for the PTP
clock callbacks added in the next patch.
ToD operations use a wait-before-write pattern to avoid blocking
after each operation.
The tod_ready_wait helper selects the poll timeout based on the
current ToD command - write operations use a longer timeout (1000 ms)
than reads (30 ms).
The ToD read captures system timestamps (ptp_system_timestamp) around
the HW command and completion poll to support cross-timestamping.
The TIE write operation provides sub-picosecond resolution phase
adjustment for modes where the DPLL is tracking a reference
(AUTO and REFLOCK).
Add output step-time mask to struct zl3073x_dev and
zl3073x_dev_out_is_stepped() helper to check if an output
participates in step-time operations.

Replace the fixed 10 us poll sleep in zl3073x_poll_zero_u8() with
timeout_us / 50, scaling the sleep interval proportionally to the
timeout for all callers.
Testing showed that existing callers (mailbox, HWREG, DF read,
frequency measurement and phase error polls with 25-50 ms timeouts)
typically completed in low hundreds of sleep cycles with the fixed
10 us interval. With the scaled interval the cycle count drops to
single digits. The longer PTP-related timeouts (up to 3000 ms for
phase step) added in the following patches benefit most, avoiding
on the order of 10^5 bus transactions per wait.

current_password_store() checks the password length before removing the
trailing newline, which can reject valid passwords that are exactly
->maxlen bytes long.
It also passes ->maxlen to strscpy(), which truncates passwords without
a newline.
Use strchrnul() to measure the password length up to the newline, then
copy that many bytes and add a trailing NUL terminator using strscpy().

vmclock_miscdev_mmap() rejects writable mappings of the shared vmclock
ABI page with -EROFS, but leaves VM_MAYWRITE set. Userspace can map the
page read-only and then upgrade it to writable with mprotect(), after
which the guest can corrupt the host-written timekeeping data (sequence
counter, UTC time, TSC offset) that the vmclock ABI defines as read-only.
Clear VM_MAYWRITE on the read-only path so the mapping cannot be
upgraded, as i915 does for its read-only objects and as fixed in drm/vc4
(CVE-2026-68445) and drm/panthor (CVE-2024-53071).

Empty NLA_NESTED attributes are valid, and bonding uses them to clear
the ARP and NS target lists. When either target attribute is empty,
nla_for_each_nested() does not execute, so err retains an uninitialized
value before it is tested. The request can consequently return an
unpredictable error after clearing the targets.
Initialize err to zero so an empty target list completes successfully.
Non-empty lists still propagate errors from __bond_opt_set() unchanged.
This issue was found by a static analysis checker and confirmed by manual
source review.
