[SPARC64]: Make cpu_present_map available earlier.
The change to kernel/sched.c's init code to use for_each_cpu() requires that the cpu_possible_map be setup much earlier. Set it up via setup_arch(), constrained to NR_CPUS, and later constrain it to max_cpus in smp_prepare_cpus(). This fixes SMP booting on sparc64. Signed-off-by: David S. Miller <davem@davemloft.net>
