Subject: [patch 01/23] git-acpi: uniprocessor compile fixes
Date: Tue, 21 Mar 2006 22:30:26 -0800 [thread overview]
Message-ID: <200603220633.k2M6XeDF019526@shell0.pdx.osdl.net> (raw)
From: Andrew Morton <akpm@osdl.org>,
Venkatesh Pallipadi <venkatesh.pallipadi@intel.com>
cpu_online_map doesn't exist if !CONFIG_SMP.
This path is rather lame and it'd be nice to fix it better.
