Hugh/Mel/Naoya/Andrew,

Andrew had already reviewed the changes in the first two patches during
the RFC phase and was okay with them. Could you please review the third
patch here as well and let me know your inputs/suggestions. Currently
the third patch has got build failures on SPARC and S390 platforms
(details of which are on the thread with possible fixes). Thank you.
