Never got the new name DIE for CPU? Might confuse people when they use /proc/sys/kernel/sched_domain/cpuX/domainY/name or sched_domain_debug_one().
In fact, CPU is also confusing because it's used for different things. But if it makes things even more confusing, i can come back to CPU
Yeah, not sure DIE is the right thing either; because there's multi-die packages that get classified under CPU :-)
Take for example the Core 2 Quad, which was 2 dual core dies glued together in a single package.
There's also the AMD bulldozer which glued two dies into a single package; but for those its not a problem because each die is a separate numa node, so there DIE would actually be the correct term and PACKAGE would be wrong.
So while CPU sucks, I'm not sure we can come up with anything that's actually correct. That said; we could try for something less wrong than CPU :-)
OK
Dietmar,
Have you got another naming that DIE that could suit better ? otherwise i will keep it
If backward compatibility is not an issue here, keep it.

I'm not sure there are a lot of people who see/know the names of these domains to be bothered by a change in them; it might be limited to just us for all I know.
