percpu data for non-existant cpus

It was neccessary in 2.4 to allocate cpu_data areas for
non-existent cpus. I forget where, but some generic
initialization code expected to be able to reference cpu_data
for all cpus up to NR_CPUS.

Does 2.6 have the same requirement or can I allocate cpu_data
areas only for cpus that exist or might exist (cpu_possible()).
