This fixes several issues in GC and other runtime code showing on PPC64.
- Accessing arrays in CMS (compactibleFreeListSpace.cpp)
- CMS: Do release when marking a card dirty. The release must only be done if GC is running. (several files)
- method counter initialization (method.hpp).
- Order accessing f1/f2 in constant pool cache.
- Release stores in OopMapCache constructor (instanceKlass.cpp).
- BiasedLocking: Release setting object header to displaced mark.
- Release state of nmethod sweeper (sweeper.cpp).
- Do barriers when writing the thread state (thread.hpp).
---------------------------------
This is preparation for PPC64 integration: http://openjdk.java.net/jeps/175
This and following ppc64 changes will go into staging repository first and tested there: http://hg.openjdk.java.net/ppc-aix-port/stage/
