Subject: [PATCH v2 01/12] linux-user: elfload: Add more initial s390x PSW bits
Date: Tue, 4 Jul 2023 10:12:25 +0200 [thread overview]
Message-ID: <20230704081506.276055-2-iii@linux.ibm.com> (raw)
In-Reply-To: <20230704081506.276055-1-iii@linux.ibm.com>
Make the PSW look more similar to the real s390x userspace PSW.
Except for being there, the newly added bits should not affect the
userspace code execution.
Reviewed-by: David Hildenbrand <david@redhat.com>
