From d2f019fe40e8fecd822f87bc759f74925a5c31d6 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Fri, 14 Nov 2008 18:18:09 +0100 Subject: [PATCH] [S390] fix s390x_newuname 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.
