* @name: Name of the boot protocol.

* @cpu_start: Boots a cpu into the kernel.
* @cpu_disable: Prepares a cpu to die. May fail for some

* unplug to be aborted. Called from the cpu to be killed.
* @cpu_stop: Makes a cpu leave the kernel. Must not fail. Called from
* the cpu being stopped.
* @cpu_is_stopped: Ensures a cpu has left the kernel. Called from another
