ASoC: Fixes for v7.3

A relatively large pile of fixes here, a lot of driver specific stuff
that's broadly unremarkable plus a few core fixes from Richard that fix
issues where SoundWire systems with multiple CODECs on the same link
would configure the CODECs to use the same bus slots leading to broken
audio.

The other two are low-hanging fruits from Lorenzo's recent kbuild
speed-up patch set that fix older symbol leakages.

- don't delete in-flight filechk temporaries in asm-headers

A rule for generating header files was changed from using make
$(wildcard) fnglob to 'find' instead; as 'find' finds "hidden"
files by default, temporary files from Kbuild's 'filechk', used for
generating asm header files, may get deleted and break header file
generating.

scripts/mksysmap: fix escape of '$' in the __pi_ pattern

Commit b18b047002b7 ("kbuild: change scripts/mksysmap into sed script")
converted scripts/mksysmap from a shell script to a sed script.

However an error was made - escaping of '$' required \\ escaping in shell
but only \ in a sed script.

This was mostly corrected in commit 7a6c355b55c0 ("scripts/mksysmap: Fix
escape chars '$'"), but this fix missed arm64 PIE namespace local symbols
like __pi_$x and __pi_$d which appear in System.map and /proc/kallsyms:

$ grep __pi_\\$ /proc/kallsyms | sort -u
0000000000000000 d __pi_$d
0000000000000000 t __pi_$x

Fix the escaping properly.

scripts/mksysmap: drop the MODULE_INFO() symbols from kallsyms

Commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped")
keeps .modinfo symbols out of System.map and kallsyms, which assumes unique
IDs have a format like '__UNIQUE_ID_modinfo123'.

However, commit afb026b6d35c ("compiler: Tweak __UNIQUE_ID() naming"), sent
in the same cycle, changes this to '__UNIQUE_ID_modinfo_123'.

As a result this regexp has never matched and every kernel since v6.18 has
carried one kallsyms entries for every MODULE_INFO() declaration in the
kernel whether the modules are compiled or not.

That's 5,810 entries for an x86 defconfig build and 15,200 for arm64.

On x86 defconfig that is 113 KiB of kallsyms tables and 32 KiB of bzImage,
and every lookup walks past them.

Fix the pattern.

- Extend modules.builtin.modinfo to include module aliases from
MODULE_DEVICE_TABLE for builtin modules so that userspace tools (such
as kmod) can verify that a particular module alias will be handled by
a builtin module

- Bump the minimum version of LLVM for building the kernel to 15.0.0

- Upgrade several userspace API checks in headers_check.pl to errors

- Unify and consolidate CONFIG_WERROR / W=e handling

- Turn assembler and linker warnings into errors with CONFIG_WERROR /
W=e

- Respect CONFIG_WERROR / W=e when building userspace programs
(userprogs)

- Enable -Werror unconditionally when building host programs
(hostprogs)

- Support copy_file_range() and data segment alignment in gen_init_cpio
to improve performance on filesystems that support reflinks such as
btrfs and XFS

- Miscellaneous small changes to scripts and configuration files

Merge patch series "Add generated modalias to modules.builtin.modinfo"

Alexey Gladkov says:

The modules.builtin.modinfo file is used by userspace (kmod to be specific) to
get information about builtin modules. Among other information about the module,
information about module aliases is stored. This is very important to determine
that a particular modalias will be handled by a module that is inside the
kernel.

There are several mechanisms for creating modalias for modules:

The first is to explicitly specify the MODULE_ALIAS of the macro. In this case,
the aliases go into the '.modinfo' section of the module if it is compiled
separately or into vmlinux.o if it is builtin into the kernel.

The second is the use of MODULE_DEVICE_TABLE followed by the use of the
modpost utility. In this case, vmlinux.o no longer has this information and
does not get it into modules.builtin.modinfo.

For example:

$ modinfo pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30
modinfo: ERROR: Module pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30 not found.

$ modinfo xhci_pci
name: xhci_pci
filename: (builtin)
license: GPL
file: drivers/usb/host/xhci-pci
description: xHCI PCI Host Controller Driver

The builtin module is missing alias "pci:v*d*sv*sd*bc0Csc03i30*" which will be
generated by modpost if the module is built separately.

To fix this it is necessary to add the generated by modpost modalias to
modules.builtin.modinfo. Fortunately modpost already generates .vmlinux.export.c
for exported symbols. It is possible to add `.modinfo` for builtin modules and
modify the build system so that `.modinfo` section is extracted from the
intermediate vmlinux after modpost is executed.

modpost: Create modalias for builtin modules

For some modules, modalias is generated using the modpost utility and
the section is added to the module file.

When a module is added inside vmlinux, modpost does not generate
modalias for such modules and the information is lost.

As a result kmod (which uses modules.builtin.modinfo in userspace)
cannot determine that modalias is handled by a builtin kernel module.

$ cat /sys/devices/pci0000:00/0000:00:14.0/modalias
pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30

description: xHCI PCI Host Controller Driver

Missing modalias "pci:v*d*sv*sd*bc0Csc03i30*" which will be generated by
modpost if the module is built separately.

To fix this it is necessary to generate the same modalias for vmlinux as
for the individual modules. Fortunately '.vmlinux.export.o' is already
generated from which '.modinfo' can be extracted in the same way as for
vmlinux.o.
