      [S390] Fix smsgiucv init on no iucv machines · 0fc3ddd6
      Christian Borntraeger 提交于
      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 提交于
      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.
