[S390] Support for disconnected devices reappearing on another subchannel.
- create a 'pseudo_subchannel' per channel subsystem (the 'orphanage') - use the orphanage as a shelter for ccw_devices that can't remain on the same subchannel Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
