Merge tag 'kbuild-7.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linux

Pull Kbuild / Kconfig updates from Nathan Chancellor:
 "Kbuild:

   - Remove broken module linking exclusion for BTF

   - Add documentation around how offset header files work

   - Include unstripped vDSO libraries in pacman packages

   - Bump minimum version of LLVM for building the kernel to 17.0.1 and
     clean up unnecessary workarounds

   - Use a context manager in run-clang-tools

   - Add dist macro value if present to release tag for RPM packages

   - Detect and report truncated buf_printf() output in modpost

   - Add __llvm_covfun and __llvm_covmap to section whitelist in modpost

   - Support Clang's distributed ThinLTO mode

   - Remove architecture specific configurations for AutoFDO and
     Propeller to ease individual architecture maintenance

  Kconfig:

   - Add kconfig-sym-check target to look for dangling Kconfig symbol
     references and invalid tristate literal values

   - Harden against potential NULL pointer dereference

   - Fix typo in Kconfig test comment"
