Please update this feature with the outstanding actions needed for this to be ready for 17.04.
Gery - this is status that needs to be reflected in the weekly UPM meeting.

The latest version has been posted here:
https://marc.info/?l=linuxppc-embedded&m=148215354725740&w=2

It has been acked by the Kprobes maintainer and is awaiting powerpc maintainer review. We expect this to land in kernel v4.11.
