Don't refer to stop_machine() in the CPU hotplug path, since we are going
to get rid of it. Also, move the comment referring to callback adoption
to the CPU_DEAD case, because that's where it happens now.

Ouch!  That comment is indeed obsolete and must die.

I queued this to -rcu with your Signed-off-by.  However, I omitted
the added comment, as it is imcomplete -- it is easy to look at
rcu_cleanup_dead_cpu() to see what it does.

Cool! I'll drop it from my patch series then. Thank you!
