The kernel could preserve that state across suspend, but it doesn't have to
be the kernel's job. user-space should apply the configured policy for CPU
hotplug events. This would ensure correct behaviour in all CPU hotplug
cases, not just suspend-resume where the kernel hot-unplugs all but one CPU
before suspend. (This is maybe only likely to happen with virtual machines,
because most desktop hardware isn't physically hotplug safe. And AFAIK Xen
prevents cpufreq from working.)
