[PATCH] s390: multiple subchannel sets support
Add support for multiple subchannel sets. Works with arbitrary devices in subchannel set 1 and is transparent to device drivers. Although currently only two subchannel sets are available, this will work with the architectured maximum number of subchannel sets as well.
