[PATCH]add an ifdef in sched.c

[andyliu]

hi

I have found that in sched.c. the macro for_each_domain only useful
for the config
that has CONFIG_SMP defined. so i add an ifdef in sched.c.

below is the patch

--- linux-2.6.10-rc1/kernel/sched.c     2004-10-23 05:40:05.000000000 +0800
+++ linux-2.6.10-rc1-new/kernel/sched.c 2004-11-04 16:34:55.000000000 +0800

 static DEFINE_PER_CPU(struct runqueue, runqueues);

-#define for_each_domain(cpu, domain) \
+#ifdef CONFIG_SMP
+# define for_each_domain(cpu, domain) \
        for (domain = cpu_rq(cpu)->sd; domain; domain = domain->parent)
+#endif

 #define cpu_rq(cpu)            (&per_cpu(runqueues, (cpu)))
 #define this_rq()              (&__get_cpu_var(runqueues))
