      s390/time: Migrate to new 'set-state' interface · 07aeed3f
      Viresh Kumar 提交于
      Migrate s390 driver to the new 'set-state' interface provided by
      clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.
      
      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.
      
      We weren't doing anything in the ->set_mode() callback. So, this patch
      doesn't provide any set-state callbacks.

      Stephen Powell reported the following crash on a z890 machine:

      The illegal operation was executed because of a missing facility check,
      which should have made sure that the ECAG execution would only be executed
      on machines which have the general-instructions-extension facility
      installed.
