Hi All,

Could I have some reviews for the backport of the following two fixes 
from jdk8 to 7u:
6412968 <https://bugs.openjdk.java.net/browse/JDK-6412968>: CMS: Long 
initial mark pauses
6990419 <https://bugs.openjdk.java.net/browse/JDK-6990419>: CMS: 
Remaining work for 6572569: consistently skewed work distribution in 
(long) re-mark pauses

These changes parallelize the initial-mark phase of the CMS collector 
and improve the work distribution among parallel worker threads.
Webrev: http://cr.openjdk.java.net/~poonam/6412968_6990419/webrev.00/

Original fixes:
6412968 : http://hg.openjdk.java.net/hsx/hsx25/hotspot/rev/ca9dedeebdec
6990419: http://hg.openjdk.java.net/hsx/hsx25/hotspot/rev/7b06ae405d7b

Testing:
JPRT, Customer verification testing

Thanks,
Poonam
