Subject: [PATCH 06/14] [PARISC] Populate cpu_enabled_map
Date: Mon, 14 Jul 2008 20:34:15 -0600 [thread overview]
Message-ID: <20080715023415.2528.97760.stgit@blender.achiang> (raw)
In-Reply-To: <20080715023344.2528.1836.stgit@blender.achiang>
Populate the cpu_enabled_map correctly.
Note that this patch does not actually make any decisions based
on the contents of the map.
However, as the map is presented via sysfs in:
/sys/devices/system/cpu/
It should be populated correctly.
