The following patchset is available upstream and fixes the issue here described:

PPC64: Improve TM detection for enabling RTM on Linux / POWER9
https://bugs.openjdk.java.net/browse/JDK-8203305

PPC64: Fix jtreg RTM tests after "8203305: Improve TM detection for enabling RTM on Linux / POWER9"
https://bugs.openjdk.java.net/browse/JDK-8203669

They apply cleanly to 10u and approval to push it to 10u is already
granted by Oracle.

Or apply them to the next package update due to the 10.0.2 GA on July
2018... :)
