c3011b9a7d smb: client: make use of common smbdirect_socket
This is the next step in the direction of a common smbdirect layer.
Currently only structures are shared, but that will change
over time until everything is shared.

22234e37d7 smb: smbdirect: add smbdirect_socket.h
This abstracts the common smbdirect layer.

Currently with just a few things in it,
but that will change over time until everything is
in common.

Will be used in client and server in the next commits

43a67dd812 block: flip iter directions in blk_rq_integrity_map_user()
blk_rq_integrity_map_user() creates the ubuf iter with ITER_DEST for
write-direction operations and ITER_SOURCE for read-direction ones.
This is backwards; writes use the user buffer as a source for metadata
and reads use it as a destination. Switch to the rq_data_dir() helper,
which maps writes to ITER_SOURCE (WRITE) and reads to ITER_DEST(READ).

0939bd2fcf perf tools improvements and fixes for Linux v6.16:
perf report/top/annotate TUI:
 
 - Accept the left arrow key as a Zoom out if done on the first column.
 
 - Show if source code toggle status in title, to help spotting bugs with
   the various disassemblers (capstone, llvm, objdump).
 
 - Provide feedback on unhandled hotkeys.
 
 Build:
 
 - Better inform when certain features are not available with warnings in the
   build process and in 'perf version --build-options' or 'perf -vv'.
 
 perf record:
 
 - Improve the --off-cpu code by synthesizing events for switch-out -> switch-in
   intervals using a BPF program. This can be fine tuned using a --off-cpu-thresh
   knob.
 
 perf report:
 
 - Add 'tgid' sort key.
 
 perf mem/c2c:
 
 - Add 'op', 'cache', 'snoop', 'dtlb' output fields.
 
 - Add support for 'ldlat' on AMD IBS (Instruction Based Sampling).
 
 perf ftrace:
 
 - Use process/session specific trace settings instead of messing with
   the global ftrace knobs.
 
 perf trace:
 
 - Implement syscall summary in BPF.
 
 - Support --summary-mode=cgroup.
 
 - Always print return value for syscalls returning a pid.
 
 - The rseq and set_robust_list don't return a pid, just -errno.
 
 perf lock contention:
 
 -  Symbolize zone->lock using BTF.
 
 - Add -J/--inject-delay option to estimate impact on application performance by
   optimization of kernel locking behavior.
 
 perf stat:
 
 - Improve hybrid support for the NMI watchdog warning.
 
 Symbol resolution:
 
 - Handle 'u' and 'l' symbols in /proc/kallsyms, resolving some Rust symbols.
 
 - Improve Rust demangler.
 
 Hardware tracing:
 
 Intel PT:
 
 - Fix PEBS-via-PT data_src.
 
 - Do not default to recording all switch events.
 
 - Fix pattern matching with python3 on the SQL viewer script.
 
 arm64:
 
 - Fixups for the hip08 hha PMU.
 
 Vendor events:
 
 - Update Intel events/metrics files for alderlake, alderlaken, arrowlake,
   bonnell, broadwell, broadwellde, broadwellx, cascadelakex, clearwaterforest,
   elkhartlake, emeraldrapids, grandridge, graniterapids, haswell, haswellx,
   icelake, icelakex, ivybridge, ivytown, jaketown, lunarlake, meteorlake,
   nehalemep, nehalemex, rocketlake, sandybridge, sapphirerapids, sierraforest,
   skylake, skylakex, snowridgex, tigerlake, westmereep-dp, westmereep-sp,
   westmereep-sx.
 
 python support:
 
 - Add support for event counts in the python binding, add a counting.py example.
 
 perf list:
 
 - Display the PMU name associated with a perf metric in JSON.
 
 perf test:
 
 - Hybrid improvements for metric value validation test.
 
 - Fix LBR test by ignoring idle task.
 
 - Add AMD IBS sw filter ana d'ldlat' tests.
 
 - Add 'perf trace --summary-mode=cgroup' test.
 
 - Add tests for the various language symbol demanglers.
 
 Miscellaneous.
 
 - Allow specifying the cpu an event will be tied using '-e event/cpu=N/'.
 
 - Sync various headers with the kernel sources.
 
 - Add annotations to use clang's -Wthread-safety and fix some problems
   it detected.
 
 - Make dump_stack() use perf's symbol resolution to provide better backtraces.
 
 - Intel TPEBS support cleanups and fixes. TPEBS stands for Timed PEBS
   (Precision Event-Based Sampling), that adds timing info, the retirement
   latency of instructions.
 
 - Various memory allocation (some detected by ASAN) and reference counting
   fixes.
 
 - Add a 8-byte aligned PERF_RECORD_COMPRESSED2 to replace PERF_RECORD_COMPRESSED.
 
 - Skip unsupported event types in perf.data files, don't stop when finding one.
 
 - Improve lookups using hashmaps and binary searches.

607d09d1a0 io_uring/kbuf: limit legacy provided buffer lists to USHRT_MAX
The buffer ID for a provided buffer is an unsigned short, and hence
there can only be 64k added to any given buffer list before having
duplicate BIDs. Cap the legacy provided buffers at 64k in the list.
This is mostly to prevent silly stall reports from syzbot, which
likes to dump tons of buffers into a list and then have kernels with
lockdep and kasan churning through them and hitting long wait times
for buffer pruning at ring exit time.

70087d2200 tracing fixes:
- Fix UAF in module unload in ftrace when there's a bug in the module
 
   If a module is buggy and triggers ftrace_disable which is set when
   an anomaly is detected, when it gets unloaded it doesn't free
   the hooks into kallsyms, and when a kallsyms lookup is performed
   it may access the mod->modname field and crash via UAF.
 
   Fix this by still freeing the mod_maps that are attached to kallsyms
   on module unload regardless if ftrace_disable is set or not.
 
 - Do not bother allocating mod_maps for kallsyms if ftrace_disable is set
 
 - Remove unused trace events
 
   When a trace event or tracepoint is created but not used, it still
   creates the code and data structures needed for that trace event.
   This just wastes memory.
 
   A patch is being worked on to warn when a trace event is created but
   not used: https://lore.kernel.org/linux-trace-kernel/20250529130138.544ffec4@gandalf.local.home/
 
   Remove the trace events that are created but not used. This does not
   remove trace events that are created but are not used due configs
   not being set. That will be handled later. This only removes events
   that have no user under any config.

8887abccf8 PM: sleep: Add locking to dpm_async_resume_children()
Commit 0cbef962ce ("PM: sleep: Resume children after resuming the
parent") introduced a subtle concurrency issue that may lead to a kernel
crash if system suspend is aborted and may also slow down asynchronous
device resume otherwise.

Namely, the initial list walks in dpm_noirq_resume_devices(),
dpm_resume_early(), and dpm_resume() call dpm_clear_async_state() for
every device and attempt to asynchronously resume it if it has no
children (so it is a "root" device).  The asynchronous resume of a
root device triggers an attempt to asynchronously resume its children
which may take place before calling dpm_clear_async_state() for them
due to the lack of synchronization between dpm_async_resume_children()
and the code calling dpm_clear_async_state().  If this happens, the
dpm_clear_async_state() that comes in late, will clear
power.work_in_progress for the given device after it has been set by
__dpm_async(), so the suspend callback will be allowed to run once
again for the same device during the same transition.  This leads to
a whole range of interesting breakage.

Fortunately, if the suspend transition is not aborted, power.work_in_progress
is set by it for all devices, so dpm_async_resume_children() will not
schedule asynchronous resume for them until dpm_clear_async_state()
clears that flag, but this means missing an opportunity to start the
resume of those devices earlier.

Address the above issue by adding dpm_list_mtx locking to
dpm_async_resume_children(), so it will wait for the entire initial
list walk and the invocation of dpm_clear_async_state() for all devices
to be completed before scheduling any new asynchronous resume callbacks.

d46c4c839c PM: sleep: Fix power.is_suspended cleanup for direct-complete devices
Commit 03f1444016 ("PM: sleep: Fix handling devices with direct_complete
set on errors") caused power.is_suspended to be set for devices with
power.direct_complete set, but it forgot to ensure the clearing of that
flag for them in device_resume(), so power.is_suspended is still set for
them during the next system suspend-resume cycle.

If that cycle is aborted in dpm_suspend(), the subsequent invocation of
dpm_resume() will trigger a device_resume() call for every device and
because power.is_suspended is set for the devices in question, they will
not be skipped by device_resume() as expected which causes scary error
messages to be logged (as appropriate).

To address this issue, move the clearing of power.is_suspended in
device_resume() immediately after the power.is_suspended check so it
will be always cleared for all devices processed by that function.

Commits aa7a9275ab ("PM: sleep: Suspend async parents after suspending

asynchronous") added list splicing to the error paths of dpm_suspend(),
dpm_suspend_late(), and dpm_noirq_suspend_devices(), but they should
have used the list_splice_init() variant because the emptied list is
used going forward in all of these cases.

appropriate.

269c1d1443 drm/amd/display: replace fast_validate with enum dc_validate_mode
[Why]
The boolean fast_validate is used as an
input parameter in multiple functions. To
support more scenarios, we are
replacing it with enum dc_validate_mode.

[How]
The enum dc_validate_mode introduces three
possible values:
1) DC_VALIDATE_MODE_AND_PROGRAMMING:
   Apply the mode to hardware
2) DC_VALIDATE_MODE_ONLY:
   Check whether the mode can be supported
3) DC_VALIDATE_MODE_AND_STATE_INDEX:
   Check if the mode can be supported, and
   determine the optimal voltage level
   needed to support it.

a4d04bc90d drm/amd/display: Do not bypass chroma scaling in 1:1 case
[Why]
When doing 2:1 downscaling on a YUV sub-sampled format, the chroma
scaling ratio is 1:1. Since chroma has cositing, it is needed to do
scaling on the chroma plane(s) and not to bypass chroma scaling.

[How]
Do not set the chroma taps to one when the chroma ratio is identity
and the input format is a sub-sampled YUV format.

[Why]
The quantity and duration of FAMS2 commands are set to increase
in future products. This necessitates the implementation of a new
mechanism for chaining commands together, allowing all commands
to be processed within a single transaction.

[How]
The indirect buffer acts as a shared buffer on the driver side,
mapped to DMUB's internal CW7 address. Its source address and
size are sent through mailbox command to DMUB, triggering the
transaction.

removed the events themselves. As each event created takes up memory

   - Avoid a -Wflex-array-member-not-at-end GCC warning by replacing an
     on-stack flexible structure definition with a utility function call

  Multicolor LEDs:
   - Fix issue where setting multi_intensity while software blinking is
     active could stop blinking

  PCA955x LEDs:
   - Avoid potential buffer overflow when creating default labels by
     changing a field's type to 'u8' and updating format specifiers

  PCA995x LEDs:
   - Fix a typo (stray space) in an 'of_device_id' entry in the
     'pca995x_of_match' table

  Kconfig:
   - Prevent LED drivers from being enabled by default when
     'COMPILE_TEST' is set

  Device Property API:
   - Split 'device_get_child_node_count()' into a new helper
     'fwnode_get_child_node_count()' that doesn't require a device
     struct, making the API more symmetrical

  Driver Modernization (using 'fwnode_get_child_node_count()'):
   - Update 'leds-pwm-multicolor', 'leds-ncp5623' and 'leds-ncp5623' to
     use the new 'fwnode_get_child_node_count()' helper, removing their
     custom implementation
   - As above in the USB Type-C TCPM driver

  Driver Modernization (using new GPIO setter callbacks):
   - Convert 'leds-lgm-sso' to use new GPIO line value setter callbacks
     which return an integer for error handling
   - Convert 'leds-pca955x', 'leds-pca9532' and 'leds-tca6507' to use
     new GPIO setter callbacks

  Documentation:
   - Remove the '.rst' extension for 'leds-st1202' in the documentation
     index for consistency

  LP8860 LEDs:
   - Use 'regmap_multi_reg_write()' for EEPROM writes instead of manual
     looping
   - Use scoped mutex guards and 'devm_mutex_init()' to simplify
     function exits and ensure automatic cleanup
   - Remove default register definitions that are unused when regmap
     caching is not active
   - Use 'devm_regulator_get_enable_optional()' to handle the optional
     regulator, simplifying enabling and removing manual disabling
   - Refactor 'lp8860_unlock_eeprom()' to only perform the unlock
     operation, removing the lock part and an unnecessary parameter
   - Use a 'devm' action to disable the enable-GPIO, simplifying cleanup
     and error paths, and remove the now-empty '.remove()' function

  Turris Omnia LEDs:
   - Drop unnecessary commas in terminator entries of 'struct attribute'
     and 'struct of_device_id' arrays

  MT6370 RGB LEDs:
   - Use the 'LINEAR_RANGE()' for defining 'struct linear_range' entries
     to improve robustness

  Texas Instruments TPS6131x:
   - Add new devicetree bindings for the TI TPS61310/TPS61311 flash LED
     driver"

98a46a4089 drm/amdgpu: Fix integer overflow issues in amdgpu_userq_fence.c
This patch only affects 32bit systems.  There are several integer
overflows bugs here but only the "sizeof(u32) * num_syncobj"
multiplication is a problem at runtime.  (The last lines of this patch).

These variables are u32 variables that come from the user.  The issue
is the multiplications can overflow leading to us allocating a smaller
buffer than intended.  For the first couple integer overflows, the
syncobj_handles = memdup_user() allocation is immediately followed by
a kmalloc_array():

	syncobj = kmalloc_array(num_syncobj_handles, sizeof(*syncobj), GFP_KERNEL);

In that situation the kmalloc_array() works as a bounds check and we
haven't accessed the syncobj_handlesp[] array yet so the integer overflow
is harmless.

But the "num_syncobj" multiplication doesn't have that and the integer
overflow could lead to an out of bounds access.

5cccf10f65 drm/amdgpu: disable workload profile switching when OD is enabled
Users have reported that they have to reduce the level of undervolting
to acheive stability when dynamic workload profiles are enabled on
GC 10.3.x. Disable dynamic workload profiles if the user has enabled
OD.

Fixes: b9467983b7 ("drm/amdgpu: add dynamic workload profile switching for gfx10")
