gop.c is not part of arch/x86/boot/compressed/
So I'd take a patch adding -Wunused to arch/x86/boot/compressed/Makefile
and fixing the single warning in kaslr.c
The extrawarn W=1 stuff gives a lot more (below) and there I guess I'd
take only well thought out patches, each fixing all -Wmissing-prototypes
in a single compilation unit.
