Hs-tier1-7,jdk-tier1-3 of the final patch look good.

One final note: could you update the reference to Google's paper to
also show authors and other publication info?

Something like the ACM ref on the ACM page so that people preferring
paper can more easily find it, e.g.

"Wessam Hassanein. 2016. Understanding and improving JVM GC work
stealing at the data center scale. In Proceedings of the 2016 ACM
SIGPLAN International Symposium on Memory Management (ISMM 2016). ACM,
New York, NY, USA, 46-54. DOI: https://doi.org/10.1145/2926697.2926706"

No need for a re-review for me if you change it.

Thanks,
