This seems to painlessly merge with the objtool changes I have in
queue.git/call-depth-tracking. After that all I need is the below little
patch to make it to build ppc44x_defconfig + CONFIG_DYNAMIC_FTRACE=y.

So I think these patches can go through the powerpc tree if Michael
wants. Josh you okay with that, or should we do something complicated?

I'm all for avoiding complicated, but let me try to give it a proper
review first.

Did you get a chance to review this patch set?
