Merge tag 'kbuild-fixes-7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linux

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/sorttable: Mark long_size as __maybe_unused

     Fix builds with clang-23 or newer on trees w/o commit b055f4c431
     ("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"
