can I have reviews for the backport of "8069273: Decrease Hot Card
Cache Lock contention" for 8u60?
It did only apply with minor changes, so I need re-reviews. The problems
- some previous, non-ported changed the copyright date
- 8u60 does not have size_t versions of the Atomic instructions, fixed
by casting to intptr_t (as done elsewhere in this case)
- removing the HotCardCache_lock needed to be done manually, as
somewhere the declaration order of locks changed in mutexLocker.cpp.
Note that this change is based on "JDK-8053998: Hot card cache flush
chunk size too coarse grained", which is also out for review.
