Pull Kbuild fixes from Nicolas Schier:
"Fix a build race and builds on stable branches.
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: 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.

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/sorttable: Mark long_size as __maybe_unused
When building in a kernel tree prior to commit b055f4c431e3 ("sorttable:
Move ELF parsing into scripts/elf-parse.[ch]") with clang-23 or newer,
which implements a new warning under -Wunused-but-set-variable for
static global variable, there is a warning from sorttable because
long_size is unused when MCOUNT_SORT_ENABLED is not set:
scripts/sorttable.c:452:12: error: variable 'long_size' set but not used [-Werror,-Wunused-but-set-global]
452 | static int long_size;
| ^
Mark long_size as __maybe_unused to avoid inserting more ugly #ifdef
directives while insuring the warning does not reappear, as the
aforementioned change does not alter the uses of long_size, so it
appears to be coincidence that the warning disappears after this
refactoring.

kbuild: don't delete in-flight filechk temporaries in asm-headers
Commit 2d69b891e646 ("kbuild: Support generated asm-headers in
subdirectories") switched the stale-wrapper sweep in
scripts/Makefile.asm-headers from $(wildcard $(obj)/*.h) to a find(1)
invocation, so that generated headers in subdirectories are considered.
The two do not match the same set of files. Make's $(wildcard) uses glob
semantics, where a leading '.' has to be matched explicitly, whereas
find's -name uses fnmatch() without FNM_PERIOD, so '*.h' matches
dotfiles as well. filechk writes its output to $(dir $@).tmp_$(notdir $@)
before renaming it into place, so such a scratch file, if it happens to
exist in $(obj) when the sub-make is parsed, is now picked up in
old-headers. It appears in neither generic-y, generated-y nor syscall-y,
is therefore classified as unwanted, and cmd_remove deletes it.
On x86 this races with archprepare, which lists both asm-generic and
arch/x86/include/generated/asm/cpufeaturemasks.h as prerequisites. Under
-j they run concurrently against the same directory, and the build fails

Pull xfs fixes from Carlos Maiolino:
"More than the usual amount of fixes.
The highlights here are a block under reservation fix which caused an
assert to be triggered in non-default configurations. The assert,
initially added on 7.3-rc2 just makes the problem explicit but is not
the cause. Another highlight is a missed lock/unlock mutex in the xfs
healthmonitor which was causing lockdeps warnings.
Besides those two, this also contains a myriad of fixes for random
bugs found by LLM tools in the healthmon, scrub and online repair.
A few bug fixes for zoned xfs are also included.
This also includes an accounting fix for our buffer slab cache where
the memory payload associated to each object was not being properly
accounted for.

Pull erofs updates from Gao Xiang:
"The most impactful fix here is to disable LZ4 rolling decompression
for now.
AWS folks recently found their systems could get corrupted data with
some rare, specific LZ4 datasets, and after a deeper analysis, I found
the root cause is that there could be uncontrolled backward memory
copies in the current LZ4 implementation and it breaks the assumption
of the rolling decompression optimization, since the kernel LZ4
codebase is out of our control and it needs more time to plan how to
do next, so disable LZ4 rolling decompression for now to ensure data
correctness for real production on these rare cases first. The
technical details also see the corresponding commit.
Other changes are random minor fixes.
