Original fix:
   http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/16c9c159df90
   https://bugs.openjdk.java.net/browse/JDK-8181872

8u(aarch64 platforms) webrev:
http://cr.openjdk.java.net/~dongbohe/8266191/webrev.00/

Note that JDK-8181872 got backported to OpenJDK 8u. Released with 8u252. Aarch64 port got integrated with 8u292 (JDK-8257192). Since JDK-8181872 got backported earlier, the aarch64 code is missing the aarch64 part of 
https://bugs.openjdk.java.net/browse/JDK-8181872

Testing: tier1
