ASoC: Fixes for v6.9

A relatively large set of fixes here, the biggest piece of it is a
series correcting some problems with the delay reporting for Intel SOF
cards but there's a bunch of other things. Everything here is driver
specific except for a fix in the core for an issue with sign extension
handling volume controls.

Merge tag 'hardening-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull hardening updates from Kees Cook:
"As is pretty normal for this tree, there are changes all over the
place, especially for small fixes, selftest improvements, and improved
macro usability.

Some header changes ended up landing via this tree as they depended on
the string header cleanups. Also, a notable set of changes is the work
for the reintroduction of the UBSAN signed integer overflow sanitizer
so that we can continue to make improvements on the compiler side to
make this sanitizer a more viable future security hardening option.

Summary:

- string.h and related header cleanups (Tanzir Hasan, Andy
Shevchenko)

- VMCI memcpy() usage and struct_size() cleanups (Vasiliy Kovalev,
Harshit Mogalapalli)

- selftests/powerpc: Fix load_unaligned_zeropad build failure
(Michael Ellerman)

- hardened Kconfig fragment updates (Marco Elver, Lukas Bulwahn)

- Handle tail call optimization better in LKDTM (Douglas Anderson)

- Use long form types in overflow.h (Andy Shevchenko)

- Add flags param to string_get_size() (Andy Shevchenko)

- Add Coccinelle script for potential struct_size() use (Jacob
Keller)

- Fix objtool corner case under KCFI (Josh Poimboeuf)

- Drop 13 year old backward compat CAP_SYS_ADMIN check (Jingzi Meng)

- Add str_plural() helper (Michal Wajdeczko, Kees Cook)

- Ignore relocations in .notes section

- Add comments to explain how __is_constexpr() works

- Fix m68k stack alignment expectations in stackinit Kunit test

- Convert string selftests to KUnit

- Add KUnit tests for fortified string functions

- Improve reporting during fortified string warnings

- Allow non-type arg to type_max() and type_min()

- Allow strscpy() to be called with only 2 arguments

- Add binary mode to leaking_addresses scanner

- Various small cleanups to leaking_addresses scanner

- Adding wrapping_*() arithmetic helper

- Annotate initial signed integer wrap-around in refcount_t

- Add explicit UBSAN section to MAINTAINERS

- Fix UBSAN self-test warnings

- Simplify UBSAN build via removal of CONFIG_UBSAN_SANITIZE_ALL

- Reintroduce UBSAN's signed overflow sanitizer"

string: Allow 2-argument strscpy()

Using sizeof(dst) for the "size" argument in strscpy() is the
overwhelmingly common case. Instead of requiring this everywhere, allow a
2-argument version to be used that will use the sizeof() internally. There
are other functions in the kernel with optional arguments[1], so this
isn't unprecedented, and improves readability. Update and relocate the
kern-doc for strscpy() too, and drop __HAVE_ARCH_STRSCPY as it is unused.

Adjust ARCH=um build to notice the changed export name, as it doesn't
do full header includes for the string helpers.

This could additionally let us save a few hundred lines of code:
1177 files changed, 2455 insertions(+), 3026 deletions(-)
with a treewide cleanup using Coccinelle:

lib/string: shrink lib/string.i via IWYU

This diff uses an open source tool include-what-you-use (IWYU) to modify
the include list, changing indirect includes to direct includes. IWYU is
implemented using the IWYUScripts github repository which is a tool that
is currently undergoing development. These changes seek to improve build
times.

This change to lib/string.c resulted in a preprocessed size of
lib/string.i from 26371 lines to 5321 lines (-80%) for the x86
defconfig.
