To solve that, after -rc2 comes out, I'll apply the tracing portion of this series to a branch in my tree directly on top of -rc2 and I will then use that to base my changes for the next merge window. Then the arm/kvm folks could start with that branch and add the arm/KVM portion of this series on top of it. This will prevent major merge conflicts in linux-next. Does that sound OK? -- Steve
