Yes, as I said here:

http://mail.openjdk.java.net/pipermail/hotspot-dev/2015-February/017175.html

there are JDK changes but what I had to begin with was for 7 as that's where
the bug was reported. While the HotSpot changes are pretty much the same on 7,
8 and 9, doing the JDK side has basically been a complete re-write, especially
as, unlike 7, 8 has very little recognition of ppc64le.

I now have these changes working on 8u31:

http://cr.openjdk.java.net/~andrew/rh1191652/root
http://cr.openjdk.java.net/~andrew/rh1191652/jdk

I can re-base these onto whichever OpenJDK 9 tree is appropriate and push when
reviewed under the same bug as used for the HotSpot side.
