[PATCH] x86_64/ia64 : Fix compilation error for node_to_first_cpu

Browse Source 
Fixes a compiler error in node_to_first_cpu, __ffs expects unsigned long as
a parameter; instead cpumask_t was being passed.  The macro
node_to_first_cpu was not yet used in x86_64 and ia64 arches, and so we never
hit this.  This patch replaces __ffs with first_cpu macro, similar to other
arches.
