Subject: [PATCH] stop_machine: convert cpu notifier to return encapsulate
 errno value

In commit e6bde73b07edeb703d4c89c1daabc09c303de11f ("cpu-hotplug: return
better errno on cpu hotplug failure"), the cpu notifier can return an
encapsulated errno value.

This converts the cpu notifier to return an encapsulated errno value for
stop_machine().
