From: Arnd Bergmann <arnd@xxxxxxxx>
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.
