[PATCH] sched: hardcode non-smp set_cpus_allowed

Browse Source 
Simplify the UP (1 CPU) implementatin of set_cpus_allowed.

The one CPU is hardcoded to be cpu 0 - so just test for that bit, and avoid
having to pick up the cpu_online_map.

Also, unexport cpu_online_map: it was only needed for set_cpus_allowed().
