Title:
RPT related fixes missing in Ubuntu 16.04.3
Status in The Ubuntu-power-systems project:
In Progress
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Zesty:
Fix Released
Bug description:
== SRU Justification ==
These four commits are Radix performance patches specific to powerpc.
The patches are reported to help anywhere from 40% up to 3.5X on
unixbench fork/exec testcases.
The first patch was included in mainlne as of 4.12-rc1. The last three
patches are
still in linux-next.
---Problem Description---
The following patches are missing in the ubuntu 16.04.3 kernel
https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-April/156104.html
https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-April/156105.html

ppc64le ppc64le ppc64le GNU/Linux
Machine Type = power9
---Steps to Reproduce---
Did a fork and exec benchmark to look at the performance and they
pointed to radix routines.
