      [AF_IUCV/IUCV]: smp_call_function deadlock · 04b090d5

      Calling smp_call_function can lead to a deadlock if it is called
      from tasklet context. 
      Fixing this deadlock requires to move the smp_call_function from the
      tasklet context to a work queue. To do that queue the path pending
      interrupts to a separate list and move the path cleanup out of
      iucv_path_sever to iucv_path_connect and iucv_path_pending.
      This creates a new requirement for iucv_path_connect: it may not be
      called from tasklet context anymore. 
      Also fixed compile problem for CONFIG_HOTPLUG_CPU=n and
      another one when walking the cpu_online mask. When doing this, 
      we must disable cpu hotplug.
