[PATCH] ppc32: make cur_cpu_spec a single pointer instead of an array
Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs. Additionally, made call_setup_cpu check to see if the cpu_setup pointer is NULL or not before calling the function. This lets remove the dummy cpu_setup calls that just return. Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
