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