From c8cda8748eceeeb06f1952e7e765a0919103644d Mon Sep 17 00:00:00 2001 From: Dominik Dingel Date: Mon, 17 Jun 2013 14:29:42 +0200 Subject: s390/IPL: Allow boot from other ssid than 0 We now take the subchannel set id also into account to find the boot device. If we want to use a subchannel set other than the default set 0, we first need to enable the mss facility.
