Thanks shaohua, since the initial code has been collecting dust for
some several months now, and I never got time to finish it.
Think you forgot to cc the ia64 crowd. We tried to do it a little bit more
generic way, but some required arch assist due to some differences.
Andrew: please help stage in -mm since we would need more extensive testing

It would also help to check if other archs have any compile issues etc..
