Subject[PATCH 06/14] [PARISC] Populate cpu_enabled_map
Date
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.
