PPC64: jfr profiling doesn't work (PPC64 only)

[Haug, Gunter]

Hi all,

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

https://bugs.openjdk.java.net/projects/JDK/issues/JDK-8207392?filter=allopenissues
http://cr.openjdk.java.net/~ghaug/webrevs/8207392/

JFR profiling on linux PPC64 has not been implemented correctly so far, the VM crashes when it is turned on. Therefore hotspot/jtreg/runtime/appcds/TestWithProfiler.java fails. With this fix the test succeeds. I've analyzed a couple of benchmarks with JMC and results look plausible when compared to linux x86.

Thanks and best regards,
Gunter
