Looking this over, it simply makes it _possible_ to offline CPU0, but
doesn't do it by default, correct?
I've got it queued locally and assuming the answer to my question is
what I think it is, I'll push it out soonish. Thanks.
Josh, after some additional testing it looks like we should not do this yet.
There are some odd bugs that have popped up on older hardware and a few issues
on new hardware that need to be resolved.
So ... I think this should be rejected or reverted.
Thanks,
