Requesting review of the patch for allocating old generation of g1 gc on alternate memory devices such nv-dimm.
The design of this implementation is explained on the bug page - https://bugs.openjdk.java.net/browse/JDK-8211425
Please follow the parent issue here : https://bugs.openjdk.java.net/browse/JDK-8202286.
Testing : Passed tier1_gc and tier1_runtime jtret tests.
I added extra options "-XX:+UnlockExperimentalVMOptions -XX:AllocateOldGenAt=/home/Kishor" to each test. There are some tests which I had to exclude since they won't work with this flag. Example: tests in ConcMarkSweepGC which does not support this flag, tests requiring CompressedOops to be enabled, etc.
