firmware: cs_dsp: mock_bin: Add function to create long-offset patches
Add cs_dsp_mock_bin_add_patch_off32(). This is the same as
cs_dsp_mock_bin_add_patch() except that it puts the offset in the
new 32-bit offset field and modifies the block type to indicate
that it uses the long offset.

firmware: cs_dsp: mock_bin: Pass offset32 to cs_dsp_mock_bin_add_raw_block()
Add an argument to cs_dsp_mock_bin_add_raw_block() to pass a 32-bit
offset, and change the type of the existing offset argument to u16.

The cs_dsp_test_bin_error.c test uses cs_dsp_mock_bin_add_raw_block()
so it needs corresponding updates to pass 0 as the 32-bit offset.

Version 1 and 2 of the bin file format had a 16-bit offset on blocks
and the sample rate field of the blocks was not used. Version 3 adds
new block types that change the old sample rate field to be a 32-bit
offset with the old offset currently unused.

cs_dsp_mock_bin_add_raw_block() doesn't attempt to do any magic - its
purpose is to create a raw block exactly as specified by the calling
test code. So the test case can pass a value for both offset fields.

firmware: cs_dsp: test_bin: Make patch function a test parameter
Make the call to cs_dsp_mock_bin_add_patch() a function pointer in

This is to allow for future parameterization by which function to

The new v3 file format has all the same functionality as the earlier
formats, so run all the existing test cases with a file type of 3.

bc0305cb29
firmware: cs_dsp: Handle long-offset data blocks
Handle a new type of data block that has a 32-bit offset. These are
identical to the normal blocks except that the offset is now in the
32-bit field that was previously 'sr'.

A new file version of 3 indicates that it is mandatory to process
the long-offset blocks, so that older code without that support will
reject the file.

The original 'sr' field was never used by the driver so it has been
renamed offset32.

regmap: maple: free entry on mas_store_gfp() failure
regcache_maple_write() allocates a new block ('entry') to merge
adjacent ranges and then stores it with mas_store_gfp().
When mas_store_gfp() fails, the new 'entry' remains allocated and
is never freed, leaking memory.

Free 'entry' on the failure path; on success continue freeing the
replaced neighbor blocks ('lower', 'upper').

ASoC: codecs: wsa884x: fix codec initialisation
The soundwire update_status() callback may be called multiple times with
the same ATTACHED status but initialisation should only be done when
transitioning from UNATTACHED to ATTACHED.

Fix the inverted hw_init flag which was set to false instead of true
after initialisation which defeats its purpose and may result in
repeated unnecessary initialisation.

Similarly, the initial state of the flag was also inverted so that the
codec would only be initialised and brought out of regmap cache only
mode if its status first transitions to UNATTACHED.

a2564d0688 loadpin: Implement custom proc_handler for enforce

loadpin_sysctl_table (moves into .rodata) as there is no longer need to

when loadpin_root_writable is false and the kernel var (enforce) is

stays in loadpin_check and is still set by calling sb_is_writable.

e3fe30e576 libceph: make free_choose_arg_map() resilient to partial allocation
free_choose_arg_map() may dereference a NULL pointer if its caller fails
after a partial allocation.

For example, in decode_choose_args(), if allocation of arg_map->args
fails, execution jumps to the fail label and free_choose_arg_map() is
called. Since arg_map->size is updated to a non-zero value before memory
allocation, free_choose_arg_map() will iterate over arg_map->args and
dereference a NULL pointer.

To prevent this potential NULL pointer dereference and make
free_choose_arg_map() more resilient, add checks for pointers before
iterating.

f0487a90b2 media: uvcvideo: UVC minimum relative pan/tilt/zoom speed fix.
In Video4Linux, a negative value in V4L2_CID_ZOOM_CONTINUOUS,
V4L2_CID_PAN_SPEED and V4L2_CID_TILT_SPEED indicates a movement in the
"opposite" direction to the standard direction.

Currently, we were using -UVC_GET_MIN as the negative value, which
resulted in the camera moving in the slowest possible speed.

Quirk the driver to return -UVC_GET_MAX for the affected controls.

Note that the get/set function from the mapping cannot be used for
this, because we need to use the information from GET_MAX for GET_MIN
and hacking uvc_ctrl_populate_cache seems like a worse alternative.

Tested on OBSBOT Tiny 2.

062191adfd thunderbolt: Log path activation failures without WARN backtraces
tb_path_activate() currently logs failures with tb_WARN(), which triggers
a stack trace. Transient conditions such as lane bonding or Type-C link
hiccups can fail path activation briefly, and the resulting backtraces are
noisy without aiding diagnosis.

Switch to tb_warn() for all path activation failures. The error code is
already returned to callers, and the warning still shows the message
without the backtrace.

9c214d10c5 x86,fs/resctrl: Rename some L3 specific functions
With the arrival of monitor events tied to new domains associated with a
different resource it would be clearer if the L3 resource specific functions
are more accurately named.

Rename three groups of functions:

Functions that allocate/free architecture per-RMID MBM state information:
arch_domain_mbm_alloc()		-> l3_mon_domain_mbm_alloc()
mon_domain_free()		-> l3_mon_domain_free()

Functions that allocate/free filesystem per-RMID MBM state information:
domain_setup_mon_state()	-> domain_setup_l3_mon_state()
domain_destroy_mon_state()	-> domain_destroy_l3_mon_state()

Initialization/exit:
rdt_get_mon_l3_config()		-> rdt_get_l3_mon_config()
resctrl_mon_resource_init()	-> resctrl_l3_mon_resource_init()
resctrl_mon_resource_exit()	-> resctrl_l3_mon_resource_exit()

Ensure kernel-doc descriptions of these functions' return values are present
and correctly formatted.

will have a new domain structure.

Rename the L3 resource specific domain data structures to include "l3_"
in their names to avoid confusion between the different resource specific
domain structures:
rdt_mon_domain		-> rdt_l3_mon_domain
rdt_hw_mon_domain	-> rdt_hw_l3_mon_domain

6b10cf7b6e x86,fs/resctrl: Use struct rdt_domain_hdr when reading counters
Convert the whole call sequence from mon_event_read() to resctrl_arch_rmid_read() to
pass resource independent struct rdt_domain_hdr instead of an L3 specific domain
structure to prepare for monitoring events in other resources.

This additional layer of indirection obscures which aspects of event counting depend
on a valid domain. Event initialization, support for assignable counters, and normal
event counting implicitly depend on a valid domain while summing of domains does not.
Split summing domains from the core event counting handling to make their respective
dependencies obvious.

9efb74f84b x86/sev: Disable GCOV on noinstr object
With Debian clang version 19.1.7 (3+build5) there are calls to
kasan_check_write() from __sev_es_nmi_complete(), which violates noinstr.  Fix
it by disabling GCOV for the noinstr object, as has been done for previous
such instrumentation issues.

Note that this file already disables __SANITIZE_ADDRESS__ and
__SANITIZE_THREAD__, thus calls like kasan_check_write() ought to be nops
regardless of GCOV. This has been fixed in other patches. However, to avoid
any other accidental instrumentation showing up, (and since, in principle GCOV
is instrumentation and hence should be disabled for noinstr code anyway),
disable GCOV overall as well.

Initializing automatic __free variables to NULL without need (e.g.
branches with different allocations), followed by actual allocation is
in contrary to explicit coding rules guiding cleanup.h:

"Given that the "__free(...) = NULL" pattern for variables defined at
the top of the function poses this potential interdependency problem the
recommendation is to always define and assign variables in one statement
and not group variable definitions at the top of the function when
__free() is used."

Code does not have a bug, but is less readable and uses discouraged
coding practice, so fix that by moving declaration to the place of
assignment.

6dc78c53de RDMA/mlx5: Fix ucaps init error flow
In mlx5_ib_stage_caps_init(), if mlx5_ib_init_ucaps() fails after
mlx5_ib_init_var_table() succeeds, the VAR bitmap is leaked since
the function returns without cleanup.

Thus, cleanup the var table bitmap in case of error of initializing
ucaps before exiting, preventing the leak above.
