Public bug reported:

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 :
