At which point we can also then drop it into 2.4 so that all the non IA64
architectures just happen to resolve to the same old 32bit calls via
a tiny set of #defines and the IA64 - which requires it for basically
everything anyway - can use it natively, and if they get it wrong suffer
their own problems without annoying anyone else
