How Intel does 64-bit on 32-bit Android

Intel wants to take the lead in 64-bit Android. This week, it offered some proof of how it's doing that.

Intel said this week that it's going 64-bit on 32-bit Android. Confused? Intel offered some clarification at its China developer conference this week.
Here's the initial statement Intel released this week:
"Intel...released Android KitKat 4.4 with a 64-bit kernel optimized for [Intel Architecture]. With this release, the company ported, validated, and tested the Android Open Source code on IA, taking on the work that developers typically would need to do on their own. This release will provide the...64-bit kernel support for development of next-generation devices."
Intel's Doug Fisher, general manager, Software and Services Group, expounded on this during his presentation.
He began by saying that Intel is moving everything to 64-bit now. That means it's moving all of its mobile silicon. More-traditional hardware like servers, desktops, and laptops have been 64-bit for years (servers since 2001, desktops since 2004).
But that's just half the battle, because the software needs to be 64-bit too.
So, he went on to explain and demonstrate how a kernel -- a core piece of the operating system -- that's 64-bit can begin to provide some of the benefits of a full 64-bit OS.
