Merge tag 'kbuild-fixes-7.0-4' of git://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linux

Pull Kbuild fixes from Nathan Chancellor:

 - Make modules-cpio-pkg respect INSTALL_MOD_PATH so that it can be
   used with distribution initramfs files that have a merged /usr,
   such as Fedora

 - Silence an instance of -Wunused-but-set-global, a strengthening
   of -Wunused-but-set-variable in tip of tree Clang, in modpost,
   as the variable for extra warnings is currently unused

* tag 'kbuild-fixes-7.0-4' of git://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linux:
  modpost: Declare extra_warn with unused attribute
  kbuild: modules-cpio-pkg: Respect INSTALL_MOD_PATH
