Pull compiler attributes fixes from Miguel Ojeda:
 "Clean the new GCC 9 -Wmissing-attributes warnings

  The upcoming GCC 9 release extends the -Wmissing-attributes warnings
  (enabled by -Wall) to C and aliases: it warns when particular function
  attributes are missing in the aliases but not in their target, e.g.:

    void __cold f(void) {}
    void __alias("f") g(void);

  diagnoses:

    warning: 'g' specifies less restrictive attribute than
    its target 'f': 'cold' [-Wmissing-attributes]

  These patch series clean these new warnings. Most of them are caused
  by the module_init/exit macros"
