Tejun pointed out that if we set or unset the hotplug online flag before we invoke the relevant hotplug callbacks, schedulers could get confused because they could begin receiving callbacks on a CPU before (or after) they're notified that a CPU is online (or offline). Let's reverse the order to fix that. Signed-off-by: David Vernet <void@manifault.com>
