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. # # Signed-off-by: Nicholas Piggin #
