Subject[PATCH] sched: remove __cpuinitdata anotation to cpu_isolated_map
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.
