This suppresses sparse error generated due to the recently added
rcu_assign_pointer sparse check.

error: incompatible types in comparison expression (different address
spaces)
Fix this by annotating cpufreq_update_util_data pointer with __rcu. This
will also help sparse catch any future RCU misuage bugs.

This fixes the following sparse errors in sched/fair.c:
fair.c:6506:14: error: incompatible types in comparison expression
fair.c:8642:21: error: incompatible types in comparison expression
Using __rcu will also help sparse catch any future bugs.

Made changes to various scheduler patches (Peter Zijlstra)

net: rtnetlink: Fix incorrect RCU API usage
ixgbe: Fix incorrect RCU API usage
sched/cpufreq: Annotate cpufreq_update_util_data pointer with __
rea to review / test it properly.

net: rtnetlink: Fix incorrect RCU API usage

sched/cpufreq: Fix incorrect RCU API usage
sched/topology: Annonate RCU pointers properly
rcuwait: Replace rcu_assign_pointer() with WRITE_ONCE
replaced with, say, WRITE_ONCE or smp_store_release. Or, may
be we add a new API to do it. But calls rcu_assign_pointer seems an
abuse of the RCU API unless RCU is being used.
