From f844c817d726cd2bdb431aa41c8217891ede2eaf Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 10 Sep 2010 15:08:33 +0000 Subject: [PATCH] PPC: Enable hint bits for lwarx/ldarx MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The lwarx and ldarx instructions have a bit to give some hint to the CPU which is safe to ignore. We currently refuse to accept any instruction with that bit set, as it used to be declared MBZ. Let's remove the reserved bit and make the instruction work as expected. This fixes Linux boot for ppc64. Signed-off-by: Alexander Graf Reviewed-by: Andreas Färber Signed-off-by: Edgar E.
