      [S390] Fix compile on !CONFIG_SMP. · 0d2be088
      Heiko Carstens authored
      Commit fae8b22d
      "[S390] Add per-cpu idle time / idle count sysfs attributes" causes
      a link error on !CONFIG_SMP.
      Fix this by adding some #ifdef's. Real fix would be to cleanup the
      code since we don't register a cpu on !CONFIG_SMP. But that would
      be quite a big patch. For the time being this is good enough.

      [S390] device_schedule_callback() for dcssblk. · 931bb68b
      Gerald Schaefer authored
      Unregistering a device from within a device attribute handler leads to
      a deadlock. Need to use device_schedule_callback() to unregister device
      in error path.

      [S390] Fix smsgiucv init on no iucv machines · 0fc3ddd6
      Christian Borntraeger authored
      smsgiucv is a driver that relies on iucv to work properly. If
      iucv ans smsgiucv are compiled into the kernel and run on an
      lpar the following scenario happens:
      iucv is initialized early as a subsystem. It checks for z/VM and
      returns with EPROTONOTSUPPORT. Later smsgiucv tries to run
      driver_register with iucv_bus as bus. As this bus is not
      initialized the driver core and list debugging issue several
      warnings and oopses.
      
      Solution is to let smsgiucv also check for z/VM and return
      EPROTONOTSUPPORT as well.

      [S390] cio: use INIT_WORK to initialize struct work. · 33583c36
      Heiko Carstens authored
      Use INIT_WORK to initialize struct work and don't initialize a
      struct work partial by explicitly initializing its private structures.
      Fixes the following lockdep bug because no key was assigned:
      
      INFO: trying to register non-static key.
      the code is fine but needs lockdep annotation.
      turning off the locking correctness validator.
