    Subject[PATCH 02/14] [M32R] 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.
