Request for Approval: Backport of 8147611: G1 - Missing memory barrier in start_cset_region_for_worker

[Yangfei (Felix)]

Hi,



Please approve the backport of 8147611 to 8u-dev.

This bug is biting one of our product which is based on the aarch64 Linux platform.

    As the patch changes shared code, it's better to backport it to the jdk8u master repo first.



    Bug: https://bugs.openjdk.java.net/browse/JDK-8147611

    JDK9 Changeset: http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/8fcd5cba7938



    The code change is trivial and should be easy for it to be applied to the jdk8u master repo.



Thanks,

Felix
