From 02aff3aa1772c63d82e1f160d7b60db1f9649f43 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 20 Aug 2013 08:24:29 +0200 Subject: s390/bitops: fix inline assembly constraints Fix inline assembly contraints for non atomic bitops functions. This is broken since 2.6.34 987bcdac "[S390] use inline assembly contraints available with gcc 3.3.3".
