ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

kbuild: Add top-level target for building gen_init_cpio

Add a top-level target for building gen_init_cpio to prevent re-entering
kbuild for 'modules-cpio-pkg'.

The recently introduced target 'modules-cpio-pkg' depends on
gen_init_cpio but there is no simple way to add this dependency as a
prerequisite that can be built in parallel to other recipes.

Introducing the top-level target, enables fixing this and also prepares
a possible move of gen_init_cpio from usr/ to scripts/.

Merge branch 'resolve_btfids-support-for-btf-modifications'

Ihor Solodrai says:

====================
resolve_btfids: Support for BTF modifications

This series changes resolve_btfids and kernel build scripts to enable
BTF transformations in resolve_btfids. Main motivation for enhancing
resolve_btfids is to reduce dependency of the kernel build on pahole
capabilities [1] and enable BTF features and optimizations [2][3]
particular to the kernel.

Patches #1-#4 in the series are non-functional changes in
resolve_btfids.

Patch #5 makes kernel build notice pahole version changes between
builds.

Patch #6 changes minimum version of pahole required for
CONFIG_DEBUG_INFO_BTF to v1.22

Patch #7 makes a small prep change in selftests/bpf build.

The last patch (#8) makes significant changes in resolve_btfids and
introduces scripts/gen-btf.sh. See implementation details in the patch
description.

kbuild: Sync kconfig when PAHOLE_VERSION changes

This patch implements kconfig re-sync when the pahole version changes
between builds, similar to how it happens for compiler version change
via CC_VERSION_TEXT.

Define PAHOLE_VERSION in the top-level Makefile and export it for
config builds. Set CONFIG_PAHOLE_VERSION default to the exported
variable.

Kconfig records the PAHOLE_VERSION value in
include/config/auto.conf.cmd [1].

The Makefile includes auto.conf.cmd, so if PAHOLE_VERSION changes
between builds, make detects a dependency change and triggers
syncconfig to update the kconfig [2].

For external module builds, add a warning message in the prepare
target, similar to the existing compiler version mismatch warning.

Note that if pahole is not installed or available, PAHOLE_VERSION is
set to 0 by pahole-version.sh, so the (un)installation of pahole is
treated as a version change.

See previous discussions for context [3].

dt-bindings: kbuild: Support single binding targets

Running the full 'make dt_binding_check' is slow. A shortcut is to set
DT_SCHEMA_FILES env variable to a substring of DT schema files to test.
It both limits which examples are validated and which schemas are used
to validate the examples. This is a problem because errors from other
schemas are missed. What makes validation slow is checking all examples,
so we really just need a way to test a single example.

Add a %.yaml target to validate the schema and validate the example:

make example-schema.yaml

The behavior for 'make dt_binding_check DT_SCHEMA_FILES=example-schema'
is unchanged. Really it should mirror dtbs_check and validate all the
examples with a subset of schemas, but there are lots of users of
expecting the existing behavior.

Merge tag 'tracepoints-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull unused tracepoints update from Steven Rostedt:
"Detect unused tracepoints.

If a tracepoint is defined but never used (TRACE_EVENT() created but
no trace_<tracepoint>() called), it can take up to or more than 5K of
memory each. This can add up as there are around a hundred unused
tracepoints with various configs. That is 500K of wasted memory.

Add a make build parameter of "UT=1" to have the build warn if an
unused tracepoint is detected in the build. This allows detection of
unused tracepoints to be upstream so that outreachy and the mentoring
project can have new developers look for fixing them, without having
these warnings suddenly show up when someone upgrades their kernel.

When all known unused tracepoints are removed, then the "UT=1" build
parameter can be removed and unused tracepoints will always warn. This
will catch new unused tracepoints after the current ones have been
removed.

Summary:

- Separate out elf functions from sorttable.c

Move out the ELF parsing functions from sorttable.c so that the
tracing tooling can use it.

- Add a tracepoint verifier tool to the build process

If "UT=1" is added to the kernel command line, any unused
tracepoints will trigger a warning at build time.

- Do not warn about unused tracepoints for tracepoints that are
exported

There are sever cases where a tracepoint is created by the kernel
and used by modules. Since there's no easy way to detect if these
are truly unused since the users are in modules, if a tracepoint is
exported, assume it will eventually be used by a module. Note,
there's not many exported tracepoints so this should not be a
problem to ignore them.

- Have building of modules also detect unused tracepoints

Do not only check the main vmlinux for unused tracepoints, also
check modules. If a module is defining a tracepoint it should be
using it.

- Add the tracepoint-update program to the ignore file

The new tracepoint-update program needs to be ignored by git"

Merge tag 'rust-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:

- Add support for 'syn'.

Syn is a parsing library for parsing a stream of Rust tokens into a
syntax tree of Rust source code.

Currently this library is geared toward use in Rust procedural
macros, but contains some APIs that may be useful more generally.

'syn' allows us to greatly simplify writing complex macros such as
'pin-init' (Benno has already prepared the 'syn'-based version). We
will use it in the 'macros' crate too.

'syn' is the most downloaded Rust crate (according to crates.io),
and it is also used by the Rust compiler itself. While the amount
of code is substantial, there should not be many updates needed for
these crates, and even if there are, they should not be too big,
e.g. +7k -3k lines across the 3 crates in the last year.

'syn' requires two smaller dependencies: 'quote' and 'proc-macro2'.
I only modified their code to remove a third dependency
('unicode-ident') and to add the SPDX identifiers. The code can be
easily verified to exactly match upstream with the provided
scripts.

They are all licensed under "Apache-2.0 OR MIT", like the other
vendored 'alloc' crate we had for a while.

Please see the merge commit with the cover letter for more context.

- Allow 'unreachable_pub' and 'clippy::disallowed_names' for
doctests.

Examples (i.e. doctests) may want to do things like show public
items and use names such as 'foo'.

Nevertheless, we still try to keep examples as close to real code
as possible (this is part of why running Clippy on doctests is
important for us, e.g. for safety comments, which userspace Rust
does not support yet but we are stricter).

'kernel' crate:

- Replace our custom 'CStr' type with 'core::ffi::CStr'.

Using the standard library type reduces our custom code footprint,
and we retain needed custom functionality through an extension
trait and a new 'fmt!' macro which replaces the previous 'core'
import.

This started in 6.17 and continued in 6.18, and we finally land the
replacement now. This required quite some stamina from Tamir, who
split the changes in steps to prepare for the flag day change here.

- Replace 'kernel::c_str!' with C string literals.

C string literals were added in Rust 1.77, which produce '&CStr's
(the 'core' one), so now we can write:

c"hi"

instead of:

c_str!("hi")

- Add 'num' module for numerical features.

It includes the 'Integer' trait, implemented for all primitive
integer types.

It also includes the 'Bounded' integer wrapping type: an integer
value that requires only the 'N' least significant bits of the
wrapped type to be encoded:

// An unsigned 8-bit integer, of which only the 4 LSBs are used.
let v = Bounded::<u8, 4>::new::<15>();
assert_eq!(v.get(), 15);

'Bounded' is useful to e.g. enforce guarantees when working with
bitfields that have an arbitrary number of bits.

Values can also be constructed from simple non-constant expressions
or, for more complex ones, validated at runtime.

'Bounded' also comes with comparison and arithmetic operations
(with both their backing type and other 'Bounded's with a
compatible backing type), casts to change the backing type,
extending/shrinking and infallible/fallible conversions from/to
primitives as applicable.

- 'rbtree' module: add immutable cursor ('Cursor').

It enables to use just an immutable tree reference where
appropriate. The existing fully-featured mutable cursor is renamed
to 'CursorMut'.

kallsyms:

- Fix wrong "big" kernel symbol type read from procfs.

'pin-init' crate:

- A couple minor fixes (Benno asked me to pick these patches up for
him this cycle).

Documentation:

- Quick Start guide: add Debian 13 (Trixie).

Debian Stable is now able to build Linux, since Debian 13 (released
2025-08-09) packages Rust 1.85.0, which is recent enough.

We are planning to propose that the minimum supported Rust version
in Linux follows Debian Stable releases, with Debian 13 being the
first one we upgrade to, i.e. Rust 1.85.

MAINTAINERS:

- Add entry for the new 'num' module.

- Remove Alex as Rust maintainer: he hasn't had the time to
contribute for a few years now, so it is a no-op change in
practice.

And a few other cleanups and improvements"

Pull documentation updates from Jonathan Corbet:
"This has been another busy cycle for documentation, with a lot of
build-system thrashing. That work should slow down from here on out.

- The various scripts and tools for documentation were spread out in
several directories; now they are (almost) all coalesced under
tools/docs/. The holdout is the kernel-doc script, which cannot be
easily moved without some further thought.

- As the amount of Python code increases, we are accumulating modules
that are imported by multiple programs. These modules have been
pulled together under tools/lib/python/ -- at least, for
documentation-related programs. There is other Python code in the
tree that might eventually want to move toward this organization.

- The Perl kernel-doc.pl script has been removed. It is no longer
used by default, and nobody has missed it, least of all anybody who
actually had to look at it.

- The docs build was controlled by a complex mess of makefilese that
few dared to touch. Mauro has moved that logic into a new program
(tools/docs/sphinx-build-wrapper) that, with any luck at all, will
be far easier to understand and maintain.

- The get_feat.pl program, used to access information under
Documentation/features/, has been rewritten in Python, bringing an
end to the use of Perl in the docs subsystem.

- The top-level README file has been reorganized into a more
reader-friendly presentation.

Merge drm/drm-next into drm-xe-next

Backmerging to bring in a needed dependency for the Xe VFIO
driver variant. This should ideally have been done before we
commited that, so we now have a small window in drm-xe-next
where that driver doesn't compile.

ASoC: Updates for v6.19

This is a very large set of updates, as well as some more extensive
cleanup work from Morimto-san we've also added a generic SCDA class
driver for SoundWire devices enabling us to support many chips with
no custom code. There's also a batch of new drivers added for both
SoCs and CODECs.

- Added a SoundWire SCDA generic class driver, pulling in a little
regmap work to support it.
- A *lot* of cleaup and API improvement work from Morimoto-san.
- Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm
drivers.
- Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
TAS5815, TAS5828 and TAS5830.

This also pulls in some gpiolib changes supporting shared GPIOs in the
core there so we can convert some of the ASoC drivers open coding
handling of that to the core functionality.

Merge tag 'vfs-6.19-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
"Features:

- Cheaper MAY_EXEC handling for path lookup. This elides MAY_WRITE
permission checks during path lookup and adds the
IOP_FASTPERM_MAY_EXEC flag so filesystems like btrfs can avoid
expensive permission work.

- Hide dentry_cache behind runtime const machinery.

- Add German Maglione as virtiofs co-maintainer.

Cleanups:

- Tidy up and inline step_into() and walk_component() for improved
code generation.

- Re-enable IOCB_NOWAIT writes to files. This refactors file
timestamp update logic, fixing a layering bypass in btrfs when
updating timestamps on device files and improving FMODE_NOCMTIME
handling in VFS now that nfsd started using it.

- Path lookup optimizations extracting slowpaths into dedicated
routines and adding branch prediction hints for mntput_no_expire(),
fd_install(), lookup_slow(), and various other hot paths.

- Enable clang's -fms-extensions flag, requiring a JFS rename to
avoid conflicts.

- Remove spurious exports in fs/file_attr.c.

- Stop duplicating union pipe_index declaration. This depends on the
shared kbuild branch that brings in -fms-extensions support which
is merged into this branch.

- Use MD5 library instead of crypto_shash in ecryptfs.

- Use largest_zero_folio() in iomap_dio_zero().

- Replace simple_strtol/strtoul with kstrtoint/kstrtouint in init and
initrd code.

- Various typo fixes.

Fixes:

- Fix emergency sync for btrfs. Btrfs requires an explicit sync_fs()
call with wait == 1 to commit super blocks. The emergency sync path
never passed this, leaving btrfs data uncommitted during emergency
sync.

- Use local kmap in watch_queue's post_one_notification().

- Add hint prints in sb_set_blocksize() for LBS dependency on THP"
