If you can Cc linuxppc-dev on arch/powerpc patches that would be ideal, that way my patchwork[1] picks it up. I realise this is a KVM patch so you've Cc'ed kvm-ppc but it's also a powerpc patch :) If you use scripts/get_maintainer.pl it should give you the right answer. cheers [1]: https://patchwork.ozlabs.org/project/linuxppc-dev > diff --git a/arch/powerpc/kvm/book3s_hv.c b/arch/powerpc/kvm/book3s_hv.c > index ee4a8854985e..15c2c64291f4 100644 > --- a/arch/powerpc/kvm/book3s_hv.c > +++ b/arch/powerpc/kvm/book3s_hv.c > @@ -46,6 +46,7 @@ > #include <linux/compiler.h> > #include <linux/of.h> > > +#include <asm/ftrace.h> > #include <asm/reg.h> > #include <asm/ppc-opcode.h> > #include <asm/asm-prototypes.h> > -- > 2.16.4
