-[ Upstream commit a6e60d84989fa0e91db7f236eda40453b0e44afa ]
-
-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.
-
-In particular, it triggers for all the init/cleanup_module
-aliases in the kernel (defined by the module_init/exit macros),
-ending up being very noisy.
-
-These aliases point to the __init/__exit functions of a module,
-which are defined as __cold (among other attributes). However,
-the aliases themselves do not have the __cold attribute.
-
-Since the compiler behaves differently when compiling a __cold
-function as well as when compiling paths leading to calls
-to __cold functions, the warning is trying to point out
-the possibly-forgotten attribute in the alias.
-
-In order to keep the warning enabled, we decided to silence
-this case. Ideally, we would mark the aliases directly
-as __init/__exit. However, there are currently around 132 modules
-in the kernel which are missing __init/__exit in their init/cleanup
-functions (either because they are missing, or for other reasons,
-e.g. the functions being called from somewhere else); and
-a section mismatch is a hard error.
-
-A conservative alternative was to mark the aliases as __cold only.
-However, since we would like to eventually enforce __init/__exit
-to be always marked,  we chose to use the new __copy function
-attribute (introduced by GCC 9 as well to deal with this).
-With it, we copy the attributes used by the target functions
-into the aliases. This way, functions that were not marked
-as __init/__exit won't have their aliases marked either,
-and therefore there won't be a section mismatch.
-
-Note that the warning would go away marking either the extern
-declaration, the definition, or both. However, we only mark
-the definition of the alias, since we do not want callers
-(which only see the declaration) to be compiled as if the function
-was __cold (and therefore the paths leading to those calls
-would be assumed to be unlikely).
