Subject: [PATCH] linux/init.h: include <linux/build_bug.h> and
 <linux/stringify.h>
Date: Sun, 13 Nov 2022 20:08:02 +0900
Message-Id: <20221113110802.3760705-1-masahiroy@kernel.org>
X-Mailer: git-send-email 2.34.1
MIME-Version: 1.0
Precedence: bulk
List-ID: <linux-kbuild.vger.kernel.org>
X-Mailing-List: linux-kbuild@vger.kernel.org

With CONFIG_HAVE_ARCH_PREL32_RELOCATIONS=y, the following code
fails to build:

  ---------------->8----------------
  #include <linux/init.h>

  int foo(void) { return 0; }
  core_initcall(foo);
  ---------------->8----------------

Include <linux/build_bug.h> for static_assert() and <linux/stringify.h>
for __stringify().
