Merge tag 'compiler-attributes-for-linus-v5.0-rc7' of git://github.com/ojeda/linux
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"
