From 69ba97436647f3b793f8e0784d1cde63adf241ea Mon Sep 17 00:00:00 2001 From: Carsten Otte Date: Sun, 30 Oct 2011 15:16:59 +0100 Subject: [S390] load user asce on sie_fault On sie_fault we need to switch back to user ASCE. Otherwise we get interresting effects when exiting to "userspace" while the guest space is still active.
