hm, but it's all ftrace bits. Could this go through the tracing 
tree? That's how it's generally done for most cross-arch 
subsystems. By having it in a separate tree we risk conflicts 
and various logistics problems. It's not like the PPC tree is 
modifying its ftrace.c file all that frequently, right?
