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?
