This is a feature request for Ubuntu 16.10:

Optimized kprobes support for powerpc :
This feauture aims to enhance the performance of kprobes. Currently, whenever a 
probe is placed in the kernel using the kprobes infrastructure, it places a 
trap instruction at that place. This feature will replace the trap with a 
branch thereby reducing the probe overhead drastically.

Patches to enable this are being sent :
