Subject: [PATCH 07/14] [POWERPC] Populate cpu_enabled_map
Date: Mon, 14 Jul 2008 20:34:20 -0600	[thread overview]
Message-ID: <20080715023420.2528.44404.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.
