Subject: [PATCH] linux/init.h: include <linux/build_bug.h> and
 <linux/stringify.h>

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().
