From: Arnd Bergmann <arnd@arndb.de> This addresses all arm64 specific protype warnings. As with the arm32 patches, the majority of them should be straightforward, either adding an #include statement to get the right header, or ensuring that an unused global function is left out of the build when the prototype is hidden. The ones that are a bit awkward are those that just add a prototype to shut up the warning, but the prototypes are never used for calling the function because the only caller is in assembler code. I tried to come up with other ways to shut up the compiler, and ideally this would be triggered by the 'asmlinkage' keyword as Ard suggested in the past, but I could not come up with a way to do this. All of the warnings have to be addressed in some form before the warning can be enabled by default.
