It needs to be wrapped in a set of synchronization hypervisor calls (H_Join). When the H_Join calls are made on all CPUs, the intent is that only one will return with H_Continue, meaning that he is the "last man standing". That CPU then issues the ibm,suspend-me call. What is interesting, of course, is that the CPU running when the rtas syscall is made, may NOT be the CPU that ultimately executes the ibm,suspend-me rtas call.
