RFR(S): 8206919: Add missing CPU/system info to vm_version_ext on s390

[Haug, Gunter]

Hi all,

can I please have reviews and a sponsor for the following tiny fix:

https://bugs.openjdk.java.net/browse/JDK-8206919
http://cr.openjdk.java.net/~ghaug/webrevs/8206919/

The solution is the same as the one we have on ppc and it suffers from the same shortcoming: there is no obvious way to detect the number of cores/slots on a s390 system. Anyway, it would be better to have information on the virtualization of the system. We do have a solution for that at SAP and we would be happy to adopt it to JFR and contribute it if there is any interest.

Thanks and best regards,
Gunter
