/**
* struct cpu_operations - Callback operations for hotplugging CPUs.
*
* @name: Name of the property as appears in a devicetree cpu node's
* enable-method property. On systems booting with ACPI, @name
* identifies the struct cpu_operations entry corresponding to
* the boot protocol specified in the ACPI MADT table.
* @cpu_init: Reads any data necessary for a specific enable-method for a
* proposed logical id.
* @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 CPU.
* @cpu_boot: Boots a cpu into the kernel.
* @cpu_postboot: Optionally, perform any post-boot cleanup or necesary
* synchronisation. Called from the cpu being booted.
* @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_die: Makes a cpu leave the kernel. Must not fail. Called from the
* cpu being killed.
* @cpu_kill: Ensures a cpu has left the kernel. Called from another cpu.
* @cpu_init_idle: Reads any data necessary to initialize CPU idle states for
* a proposed logical id.
* @cpu_suspend: Suspends a cpu and saves the required context. May fail owing
* to wrong parameters or error conditions. Called from the
* CPU being suspended. Must be called with IRQs disabled.
