Hi Mikael, Looks good to me. I just noticed g1MonitoringSupport.cpp needs a copyright bump.
Thanks for the review, I'll update the copyright year before pushing.

G1CollectorPolicy contains copies of the linked list heads and tails present in YoungList. In order to reduce the size of the G1CollectorPolicy, I suggest we remove them and have the policy access the ones in YoungList instead.
