Subject: cpufreq: unexport (un)lock_policy_rwsem* functions
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

-When:	2.6.33
-Why:	cpu_policy_rwsem has a new cleaner definition making it local to
