[GIT PULL] Kbuild fixes for 7.3 #1

Hi Linus,

please consider pulling these four Kbuild fixes for 7.3.

The first one fixes a build race, the second one fixes builds on stable
branches.

The last two are low-hanging fruits from Lorenzo's recent kbuild speed-up patch
set that fix older symbol leakages; they qualify for kbuild-fixes scarcely, but
in order to accelerate the patch set incorporation it would be great if you'd
take these, too.

Thanks and kind regards,
Nicolas

  scripts/mksysmap: fix escape of '$' in the __pi_ pattern (2026-09-12 20:01:19 +0200)

----------------------------------------------------------------
First round of Kbuild fixes for 7.3

 - kbuild: 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/sorttable: Mark long_size as __maybe_unused

   Fix builds with clang-23 or newer on trees w/o commit b055f4c431e3
   ("sorttable: Move ELF parsing into scripts/elf-parse.[ch]");
   targetting for backport to stable kernels < 6.19.

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

   Update regexp to remove kallsyms entries from kernel binary, saves
   about 32 KiB of bzImage.

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

   Prevent arm64 PIE namespace local symbols from appearing System.map
   and /proc/kallsyms.
