[PATCH] powerpc: special-case ibm,suspend-me RTAS call
Handle the ibm,suspend-me RTAS call specially. 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.
