Uses of RCU for dynamically changeable NMI handlers need to use the new rcu_dereference() and rcu_assign_pointer() facilities. This change makes it clear that these uses are safe from a memory-barrier viewpoint, but the main purpose is to document exactly what operations are being protected by RCU. This has been tested on x86 and x86-64, which are the only architectures affected by this change.
