[PATCH] sched: remove __cpuinitdata anotation to cpu_isolated_map

[PATCH] sched: remove __cpuinitdata anotation to cpu_isolated_map

[Tim Chen]

The structure cpu_isolated_map is used not only during initialization. 
Multi-core scheduler configuration changes and exclusive cpusets 
use this during run time.  During setting of sched_mc_power_savings
 policy, this structure is accessed to update sched_domains.

Thanks.
