x86: address -Wmissing-prototype warnings

From: Arnd Bergmann <[email protected]>

This addresses all x86 specific prototype warnings. The majority of the patches 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 using the asmlinkage annotation, but with no success.

All of the warnings have to be addressed in some form before the warning can be enabled by default.
