Heiko Carstens 51dbedee2f s390/percpu: add READ_ONCE() to arch_this_cpu_to_op_simple() 
commit e3f360db08d55a14112bd27454e616a24296a8b0 upstream.

Make sure that *ptr__ within arch_this_cpu_to_op_simple() is only
dereferenced once by using READ_ONCE(). Otherwise the compiler could
generate incorrect code.
