The rcu_dereference() call in core/rtw_mlme.c is no longer there in mainline 
3.17, thus it was removed some time ago.

There is a similar reference in os_dep/recv_linux.c. Perhaps it should be removed.

This problem shows the importance of working with the latest pull of the staging 
repo when working with staging code. Even then patches may suffer mid-air 
collisions if multiple devs are working on a particular piece of code.
