RFR: 8241354: ZGC: fatal error: Failed to get NUMA id due to get_mempolicy operation not permitted

[jiefu(傅杰)]

Hi all,

JBS:    https://bugs.openjdk.java.net/browse/JDK-8241354
Webrev: http://cr.openjdk.java.net/~jiefu/8241354/webrev.00/

A VM fatal error may be observed if ZGC is used.

The background is that some of our products will run in the docker.
For some safety reason, SYS_get_mempolicy is not allowed in the docker.

It might be not a good practice to generate a fatal error when get_mempolicy fails.
What do you think?

Thanks a lot.
Best regards,
Jie
