Subject: [Qemu-devel] [PATCH 16/22] target/i386: move cpu_sync_bndcs_hflags() function
Date: Tue,  4 Jul 2017 13:12:09 +0200	[thread overview]
Message-ID: <1499166735-39360-17-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1499166735-39360-1-git-send-email-pbonzini@redhat.com>

From: Yang Zhong <yang.zhong@intel.com>

Move cpu_sync_bndcs_hflags() function from mpx_helper.c
to helper.c because mpx_helper.c need be disabled when
tcg is disabled.
