Ilya Leoshkevich c9c260681f s390/preempt: mark all functions __always_inline 
preempt_count-related functions are quite ubiquitous and may be called
by noinstr ones, introducing unwanted instrumentation. Here is one
example call chain:

  irqentry_nmi_enter()  # noinstr
    lockdep_hardirqs_enabled()
      this_cpu_read()
        __pcpu_size_call_return()
          this_cpu_read_*()
            this_cpu_generic_read()
              __this_cpu_generic_read_nopreempt()
                preempt_disable_notrace()
                  __preempt_count_inc()
                    __preempt_count_add()

They are very small, so there are no significant downsides to
force-inlining them.
