Revision 834a846eee9588ac672cb504677490c28b597871 authored by Cornelia Huck on 02 May 2018, 12:52:21 UTC, committed by Michael Roth on 21 June 2018, 01:45:02 UTC 
s390-ccw: force diag 308 subcode to unsigned long
 
We currently pass an integer as the subcode parameter. However,
the upper bits of the register containing the subcode need to
be 0, which is not guaranteed unless we explicitly specify the
subcode to be an unsigned long value.
