[PATCH] mask ADT: remove x86_64 topology.h cpumask hack [20/22]

[Paul Jackson]

Patch_20_of_22 - Remove cpumask hack from asm-x86_64/topology.h
	This file had the cpumask cpu_online_map as type
	unsigned long, instead of type cpumask_t, for no good
	reason that I could see.  So I changed it.  Everywhere
	else, cpu_online_map is already of type cpumask_t.
