Patch 14/23 - Bitmaps, Cpumasks and Nodemasks

[Paul Jackson <pj@sgi.com>]

P14.cpumask_x86_64_online - 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.
