[PATCH v2 1/2] target/i386: Remove split lock detect in Snowridge CPU mo


From: Chenyi Qiang
Subject: [PATCH v2 1/2] target/i386: Remove split lock detect in Snowridge CPU model
Date: Fri, 27 Aug 2021 14:48:17 +0800

At present, there's no mechanism intelligent enough to virtualize split
lock detection correctly. Remove it in Snowridge CPU model to avoid the
feature exposure.
