From: Amerigo Wang <amwang@xxxxxxxxxx>
lock_policy_rwsem_* and unlock_policy_rwsem_* functions are scheduled to
be unexported when 2.6.33. Now there are no other callers of them out of
cpufreq.c, unexport them and make them static.

-What: lock_policy_rwsem_* and unlock_policy_rwsem_* will not be
- exported interface anymore.
-When: 2.6.33
-Why: cpu_policy_rwsem has a new cleaner definition making it local to
- cpufreq core and contained inside cpufreq.c. Other dependent
- drivers should not use it in order to safely avoid lockdep issues.
