From 075dfd82102d2048e43e1cbf48d558d915c50072 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 13 Jan 2014 13:35:16 +0100 Subject: [PATCH] s390/compat: fix PSW32_USER_BITS definition PSW32_USER_BITS should define the primary address space for user space instead of the home address space. Symptom of this bug is that gdb doesn't work in compat mode. The bug was introduced with e258d719ff28 "s390/uaccess: always run the kernel in home space" and f26946d7ecad "s390/compat: make psw32_user_bits a constant value again".
