From 521674e4ffad2b2fc8c56cd79e4b2c07c074e9cb Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 14 May 2012 12:58:26 +0200 Subject: s390/claw: remove "eieio" calls If the code really depends on ordering it's already racy. The additional memory barriers (eieio) don't help with that. If the code is not racy the memory barriers also aren't needed. In any case, just remove them.
