Heiko Carstens 5bd418784a [S390] cpu hotplug: fix external interrupt subclass mask handling
When disabling a cpu all external interrupt subclass masks in control
register 0 get cleared. However instead of the service signal subclass
mask bit an unused bit got cleared.
Accidently (or luckily) the service subclass mask gets cleared with the
pfault_fini() call that happens just before the rest of the subclass
mask bits get cleared.
