Recent changes to kernel/module.c caused the following compile
error:

  kernel/module.c: In function ‘show_taint’:
  kernel/module.c:1024:2: error: implicit declaration of function ‘module_flags_taint’ [-Werror=implicit-function-declaration]
  cc1: some warnings being treated as errors

Correct this error by moving the definition of module_flags_taint
outside of the #ifdef CONFIG_MODULE_UNLOAD section.
