Could the following enhancement backport be approved, please?

Bug		: https://bugs.openjdk.java.net/browse/JDK-8168318
Review		: http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2016-October/024771.html
Changeset	: http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/622d3fe587f2

An improvement of ~1% was observed on some Neo4j benchmarks with that change
applied. This is a significant ppc64-only performance improvement and applies
cleanly. It's low risk and does not affect any of the Oracle platforms in any
way. The proposed integration date is as soon as granted since there is no
remaining work to be done.

Thank you.

Best regards,
