Hi Linus,

Please pull these changes to clean up the new GCC 9 warnings coming from
-Wmissing-attributes. With this, we can avoid disabling them.

The patches have been for quite in -next in several forms/shapes during
the iterations we did.

Cheers,
Miguel

  include/linux/module.h: copy __init/__exit attrs to init/cleanup_module (2019-02-15 19:52:56 +0100)

----------------------------------------------------------------
Compiler Attributes: 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.
