I'm not sure we should do one patch per warning - that's too granulary. What I did earlier was this: make allmodconfig make W=1 arch/x86/kernel/apic/ and then looked at all those -Wmissing-prototypes warnings. Once I've fixed them, I commit the result as a x86/apic: Fix -Wmissing-prototypes warnings and this way it is more or less per subsystem or folder or whatever, which still keeps the amount of patches sane for further handling. Now, I did some fixes here so I'd suggest you do all your patches ontop of tip/master after merging this branch into it: https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/log/?h=tip-ras-core I'll push it into tip the next days.
