[PATCH] powerpc: Don't start secondary CPUs in a UP && KEXEC kernel
Because smp_release_cpus() is built for SMP || KEXEC, it's not safe to
unconditionally call it from setup_system(). On a UP && KEXEC kernel we'll
start up the secondary CPUs which will then go beserk and we die.
Simple fix is to conditionally call smp_release_cpus() in setup_system(). With
that in place we don't need the dummy definition of smp_release_cpus() because
all call sites are #ifdef'ed either SMP or KEXEC.
