+Subject: [PATCH] fix s390x_newuname
+
+From: Martin Schwidefsky <schwidefsky@de.ibm.com>
+
+The uname system call for 64 bit compares current->personality without
+masking the upper 16 bits. If e.g. READ_IMPLIES_EXEC is set the result
+of a uname system call will always be s390x even if the process uses
+the s390 personality.
