This is all in order to get a clean AM-infinity technology in place, that is something that rival architectures like x64 cannot match. 32-bit and 64-bit programs can co-exist in the exact same AM-infinity environment. I'm not familiar with z/Linux, but I assume 32-bit modules in z/Linux are currently run as AM31 instead of AM64 too. z/OS could lead the way to changing that. >What additional changes will you need next in > z/OS in order to support this addressing mode > that IBM hasn't seen a need for?

It's not AM32, it's AM-infinity, and it's the gold standard of computing as far as I can tell. People should migrate to z/Arch instead of x64 because x64 is likely to be saddled by needing special modes for 32 and 64 that don't exist on a pure 64-bit z/Arch. And there's no downside. 32-bit programs get access to a full 32-bit virtual memory, and 64-bit programs get access to a full 64-bit virtual memory. BFN.
