[PATCH 05/14] [MIPS] Populate cpu_enabled_map

From: Alex Chiang
Date: Mon Jul 14 2008 - 22:36:33 EST


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.
