There's kernel support for the bigLITTLE architecture in some ARM chips,
but since it depends on being able to migrate execution streams between
them, the various processors really *do* need to be compatible.

You *really* don't want to try to make things work when some cores are
ARM6 and some are ARM7, for instance - that way lies madness if you ever
reschedule onto a different processor (and I'm not even sure our toolchains
are able to generate a mixed-architecture binary without complaint).
