The following webrev against jdk9/hs-rt fixes AArch64 after it was
broken by JDK-8122937:

  http://cr.openjdk.java.net/~adinn/8129584/webrev/

It is an AArch64-only patch. Could AArch64 reviewers please check it is
ok? I'll also need someone to push it as I am not a committer. Thanks.

regards,


Andrew Dinn
