Has anyone tried hugepages with UEK2 kernel?

According to the press release:
http://www.oracle.com/us/corporate/press/1555025

"Transparent Hugepages: automatically organizes memory in larger units to reduce memory management overhead and improve stability for memory-intensive workloads."

Are AMM and hugepages now compatible with UEK2? Does it use larger page size than 2M?
