Hi,

JDK-8255479 is backported to 11.0.11-oracle. I'd like to backport it for parity.
Change doesn't apply cleanly. I had to integrate 2 small hunks manually:
1. g1BarrierSetAssembler_aarch64.cpp: Unrelated context change.
2. macroAssembler_aarch64.cpp: Unrelated context change, minor differences in code which gets removed by this change.

Bug:
https://bugs.openjdk.java.net/browse/JDK-8255479

Original change:
https://github.com/openjdk/jdk/commit/695117f8

11u backport:
http://cr.openjdk.java.net/~mdoerr/8255479_aarch64_11u/webrev.00/

Please review.

Best regards,
Martin
