History
M Hightower 38d8b6efde Added memory fence to xt_rsil() (#6301) 
Without this the compiler may use memory references loaded to registers before the fence, in computation within the fence. These values could have changed before xt_rsil()
(critical section start) was called.
Note: this is needed to stop the compiler from reordering instructions at the critical section boundary.
