[patch 1/1] export cpu_online_map

[akpm@osdl.org]

From: Andrew Morton <akpm@osdl.org>

With CONFIG_SMP=n:

*** Warning: "cpu_online_map" [drivers/firmware/dcdbas.ko] undefined!

due to set_cpus_allowed().

Questions:

- Why isn't set_cpus_allowed() just a no-op on UP?  Or some trivial thing
  which tests for cpu #0?

- Why does cpu_online_map even exist on CONFIG_SMP=n?
