Some patches touch core tracing code, and some are arch specific. Now
the question is how do we go. I prefer that we go the path of the
tracing tree (easier for me to test). But every patch that touches MIPS
arch, needs an Acked-by from the MIPS maintainer. Which I see is Ralf
(on the Cc of this patch set.)
