[PATCH] x86: fix NMI with CPU hotplug
With CPU hotplug enabled, NMI watchdog stoped working. It appears the
violation is the cpu_online check in nmi handler. local ACPI based NMI
watchdog is initialized before we set CPU online for APs. It's quite
possible a NMI is fired before we set CPU online, and that's what happens
here.
