Subject: [patch 1/1] export cpu_online_map
Date: Tue, 25 Oct 2005 21:20:48 -0700 [thread overview]
Message-ID: <200510260421.j9Q4LGh9014087@shell0.pdx.osdl.net> (raw)
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?
