+ *
+ * Offlined-CPUs have three stages of being offline:
+ *
+ * CPU_ENABLE indicates that the CPU is participating in I/O interrupts
+ * that can be directed at a number of different CPUs.  If CPU_ENABLE
+ * is off, the CPU will not be given interrupts that can be sent elsewhere,
+ * but will still get interrupts from devices associated with that CPU only,
+ * and from other CPUs.
+ *
+ * CPU_OFFLINE indicates that the dispatcher should not allow any threads
+ * other than interrupt threads to run on that CPU.  A CPU will not have
+ * CPU_OFFLINE set if there are any bound threads (besides interrupts).
+ *
+ * CPU_QUIESCED is set if p_offline was able to completely turn idle the
+ * CPU and it will not have to run interrupt threads.  In this case it'll
+ * stay in the idle loop until CPU_QUIESCED is turned off.
+ *
+ * CPU_FROZEN is used only by CPR to mark CPUs that have been successfully
+ * suspended (in the suspend path), or have yet to be resumed (in the resume
+ * case).
+ *
+ * On some platforms CPUs can be individually powered off.
+ * The following flags are set for powered off CPUs: CPU_QUIESCED,
+ * CPU_OFFLINE, and CPU_POWEROFF.  The following flags are cleared:
+ * CPU_RUNNING, CPU_READY, CPU_EXISTS, and CPU_ENABLE.
