#     powerpc/64s/radix: optimise pte_update
#     
#     Implementing pte_update with pte_xchg (which uses cmpxchg) is
#     inefficient. A single larx/stcx. works fine, no need for the less
#     efficient cmpxchg sequence.
#     
#     Then remove the memory barriers from the operation. There is a
#     requirement for TLB flushing to load mm_cpumask after the store
#     that reduces pte permissions, which is moved into the TLB flush
#     code.
