Subject: [Qemu-devel] [PULL 9/9] kvm: always update the MPX model specific register
Date: Mon, 20 Jan 2014 15:44:11 +0100	[thread overview]
Message-ID: <1390229051-28635-10-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1390229051-28635-1-git-send-email-pbonzini@redhat.com>

The original patch from Liu Jinsong restricted them to reset or full
state updates, but that's unnecessary (and wrong) since the BNDCFGS
MSR has no side effects.
