[aarch64-port-dev ] RFR 8135018: AARCH64: Missing memory barriers for CMS collector

[Yangfei (Felix)]

Hi Liu Xin,

    Thanks for preparing a new webrev.   That looks good to me (Not a Reviewer).
I also run a jcsress with CMS on my aarch64 machine last night.
As this backport only add necessary memory barriers, risk should be low.
I will push this for you.

Felix

Hi, Reviewers,
