Bug description:
  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 :
