/*
 * To avoid the need to unnecessarily exit fully to the host kernel, an IPI to
 * a CPU thread that's running/napping inside of a guest is by default regarded
 * as a request to wake the CPU (if needed) and continue execution within the
 * guest, potentially to process new state like externally-generated
 * interrupts or IPIs sent from within the guest itself (e.g. H_PROD/H_IPI).
 *
 * To force an exit to the host kernel, kvmppc_set_host_ipi() must be called
 * prior to issuing the IPI to set the corresponding 'host_ipi' flag in the
 * target CPU's PACA. To avoid unnecessary exits to the host, this flag should
 * be immediately cleared via kvmppc_clear_host_ipi() by the IPI handler on
 * the receiving side prior to processing the IPI work.
 *
 * NOTE:
 *
 * We currently issue an smp_mb() at the beginning of kvmppc_set_host_ipi().
 * This is to guard against sequences such as the following:
