Replace unbounded sprintf() with the safer snprintf(). While the
current code works correctly, snprintf() is safer and follows secure
coding best practices.
No functional changes.

- Fix a problem where the deferred non-NCQ command would incorrectly
get completed as a failed command, if there was another command that
timed out. Found by Gemini (Guenter)
- The deferred non-NCQ command work is only supposed to run after the
last NCQ command finishes. However, because the work was never
canceled on error (e.g. a timeout), the work could incorrectly run
when commands were still in flight. Found by syzbot (me)

According to the FF-A specification (DEN0077, v1.1, §13.7), when
FFA_RXTX_UNMAP is invoked from any instance other than non-secure
physical, the w1 register must be zero (MBZ). If a non-zero value is
supplied in this context, the SPMC must return FFA_INVALID_PARAMETER.
The Arm FF-A driver operates exclusively as a guest or non-secure
physical instance where the partition ID is always zero and is not
invoked from a hypervisor context where w1 carries a VM ID. In this
execution model, the partition ID observed by the driver is always zero,
and passing a VM ID is unnecessary and potentially invalid.
Remove the vm_id parameter from ffa_rxtx_unmap() and ensure that the
SMC call is issued with w1 implicitly zeroed, as required by the
specification. This prevents invalid parameter errors and aligns the
implementation with the defined FF-A ABI behavior.

Commit e7e222ad73d9 ("cxl: Move devm_cxl_add_nvdimm_bridge() to
cxl_pmem.ko") moves devm_cxl_add_nvdimm_bridge() into the cxl_pmem file,
which has independent config compile options for built-in or module. The
call from cxl_acpi_probe() is guarded by IS_ENABLED(CONFIG_CXL_PMEM),
which evaluates to true for both =y and =m.
When CONFIG_CXL_PMEM=m, a built-in cxl_acpi attempts to reference a
symbol exported by a module, which fails to link. CXL_PMEM cannot simply
be promoted to =y in this configuration because it depends on LIBNVDIMM,
which may itself be =m.
Add a Kconfig dependency to prevent CXL_ACPI from being built-in when
CXL_PMEM is a module. This contrains CXL_ACPI to =m when CXL_PMEM=m,
while still allowing CXL_ACPI to be freely configured when CXL_PMEM is
either built-in or disabled.

devm_gpiod_get_optional() in sky81452_bl_parse_dt()
The devm_gpiod_get_optional() function may return an ERR_PTR in case of
genuine GPIO acquisition errors, not just NULL which indicates the
legitimate absence of an optional GPIO.

On 32-bit architectures, unsigned long is only 32 bits wide, which
causes 64-bit inode numbers to be silently truncated. Several
filesystems (NFS, XFS, BTRFS, etc.) can generate inode numbers that
exceed 32 bits, and this truncation can lead to inode number collisions
and other subtle bugs on 32-bit systems.
Change the type of inode->i_ino from unsigned long to u64 to ensure that
inode numbers are always represented as 64-bit values regardless of
architecture. Update all format specifiers treewide from %lu/%lx to
%llu/%llx to match the new type, along with corresponding local variable
types.
This is the bulk treewide conversion. Earlier patches in this series
handled trace events separately to allow trace field reordering for
better struct packing on 32-bit.

This series enables QoS configuration for QNOC type device which
can be found on QCS8300 platform. It enables QoS configuration
for master ports with predefined priority and urgency forwarding.
This helps in prioritizing the traffic originating from different
interconnect masters at NOC (Network On Chip).
The system may function normally without this feature. However,
enabling QoS helps optimize latency and bandwidth across subsystems
like CPU, GPU, and multimedia engines, which becomes important in
high-throughput scenarios. This is a feature aimed at performance
enhancement to improve system performance under concurrent workloads.

Remove the clock and reset entries for WDT{0,2,3} to prevent

This change is harmless as only WDT1 is used by Linux, there

The rzt2h_gpio_get_direction() function is called from
gpiod_get_direction(), which ends up being used within the __setup_irq()
call stack when requesting an interrupt.
__setup_irq() holds a raw_spinlock_t with IRQs disabled, which creates
an atomic context. spinlock_t cannot be used within atomic context
when PREEMPT_RT is enabled, since it may become a sleeping lock.
An "[ BUG: Invalid wait context ]" splat is observed when running with
CONFIG_PROVE_LOCKING enabled, describing exactly the aforementioned call
stack.
__setup_irq() needs to hold a raw_spinlock_t with IRQs disabled to
serialize access against a concurrent hard interrupt.
Switch to raw_spinlock_t to fix this.

2. Reusing existing Glymur definitions for identical NoCs.
3. Overriding the channel and buswidth, with Mahua specific values for

When a scatterlists table of a GEM shmem object of size 4 GB or more is
populated with pages allocated from a folio, unsigned int .length
attribute of a scatterlist may get overflowed if total byte length of
pages allocated to that single scatterlist happens to reach or cross the
4GB limit. As a consequence, users of the object may suffer from hitting
unexpected, premature end of the object's backing pages.

ublk_ctrl_set_size() unconditionally dereferences ub->ub_disk via
set_capacity_and_notify() without checking if it is NULL.
ub->ub_disk is NULL before UBLK_CMD_START_DEV completes (it is only
assigned in ublk_ctrl_start_dev()) and after UBLK_CMD_STOP_DEV runs
(ublk_detach_disk() sets it to NULL). Since the UBLK_CMD_UPDATE_SIZE
handler performs no state validation, a user can trigger a NULL pointer
dereference by sending UPDATE_SIZE to a device that has been added but
not yet started, or one that has been stopped.
Fix this by checking ub->ub_disk under ub->mutex before dereferencing
it, and returning -ENODEV if the disk is not available.

Driver core holds a reference to the USB interface and its parent USB
device while the interface is bound to a driver and there is no need to
take additional references unless the structures are needed after
disconnect.
Drop the redundant device reference to reduce cargo culting, make it
easier to spot drivers where an extra reference is needed, and reduce
the risk of memory leaks when drivers fail to release it.

Add a debugfs 'simulate_incumbent_signal_interference' with custom
file_operations and a .write that accepts "<freq_mhz> <bitmap>". The
handler selects the 6 GHz chanctx whose primary 20 MHz center matches
<freq_mhz> and reports the event via cfg80211_incumbent_signal_notify().
The bitmap marks affected 20 MHz segments within the current chandef
(lowest bit = lowest segment)

The action code actually serves to identify the type of action
frame, so it really isn't part of the per-type structure. Pull
it out and have it in the general action frame format.
In theory, whether or not the action code is present in this
way is up to each category, but all categories that are defined
right now all have that value.
While at it, and since this change requires changing all users,
remove the 'u' and make it an anonymous union in this case, so
that all code using this changes.
Change IEEE80211_MIN_ACTION_SIZE to take an argument which says
how much of the frame is needed, e.g. category, action_code or
the specific frame type that's defined in the union. Again this
also ensures that all code is updated.
In some cases, fix bugs where the SKB length was checked after
having accessed beyond the checked length, in particular in FTM
code, e.g. ieee80211_is_ftm().

If the ata_qc_for_each_raw() loop finishes without finding a matching SCSI
command for any QC, the variable qc will hold a pointer to the last element
examined, which has the tag i == ATA_MAX_QUEUE - 1. This qc can match the
port deferred QC (ap->deferred_qc).
If that happens, the condition qc == ap->deferred_qc evaluates to true
despite the loop not breaking with a match on the SCSI command for this QC.
In that case, the error handler mistakenly intercepts a command that has
not been issued yet and that has not timed out, and thus erroneously
returning a timeout error.
Fix the problem by checking for i < ATA_MAX_QUEUE in addition to
qc == ap->deferred_qc.
The problem was found by an experimental code review agent based on
gemini-3.1-pro while reviewing backports into v6.18.y.

Some modem devices can take significant time (up to 20 secs for sdx75) to
enter mission mode during initialization. Currently, mhi_sync_power_up()
waits for this entire process to complete, blocking other driver probes
and delaying system boot.
Switch to mhi_async_power_up() so probe can return immediately while MHI
initialization continues in the background. This eliminates lengthy boot
delays and allows other drivers to probe in parallel, improving overall
system boot performance.

QDU100 device
Enable IP_SW1 (ch:48/49), IP_ETH0 (ch:50,51) and IP_ETH1 (ch:52,
53) channels over MHI for M-plane, NETCONF and S-plane interface
for Qualcomm 5G DU X100 Accelerator Card (QDU100).
M-plane:
Used to implement DU M-Plane software for non-real-time O-RAN management
between O-DU and O-RU using NETCONF/YANG and O-RAN WG4 M-Plane YANG models.
It provides capability exchange, configuration management, performance
monitoring, and fault management per O-RAN.WG4.TS.MP.0-R004-v18.00 spec.
Netconf:
Used for configuration operations such as fetching, modifying, and deleting
network device configurations.
This interface is also used for IETF Netconf communication, with a Netconf
server on the ORU to interact with a Netconf client running on the host.
S-plane:
To support frequency and time synchronization between O-DUs and O-RUs using
Synchronous Ethernet and IEEE 1588. Assume PTP transport over L2 Ethernet
(ITU-T G.8275.1) for full timing support and to allow PTP over UDP/IP
(ITU-T G.8275.2) with reduced reliability, as per ORAN spec
O-RAN.WG4.CUS.0-R003-v12.00.
