/**
* struct cpu_operations - Callback operations for hotplugging CPUs.
*
- * @name: Name of the boot protocol.
- * @cpu_prepare: Early one-time preparation step for a cpu. If there
- * is a mechanism for doing so, tests whether it is
- * possible to boot the given HART.
* @cpu_start: Boots a cpu into the kernel.
- * @cpu_disable: Prepares a cpu to die. May fail for some
- * mechanism-specific reason, which will cause the hot
- * 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
* cpu.
