[PATCH] m32r: Fix cpu_possible_map and cpu_present_map initialization for SMP kernel

Browse Source 
This patch fixes a boot problem of the m32r SMP kernel 2.6.16-rc1-mm3 or
later.

In this patch, cpu_possible_map is statically initialized, and cpu_present_map
is also copied from cpu_possible_map in smp_prepare_cpus(), because the m32r
architecture has not supported CPU hotplug yet.
