From: Andrew Morton <[email protected]>
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?
