Subject: [PATCH] add missing guest clock update removed by e48672fa25e879f7ae21785c7efd187738139593
Date: Mon, 7 Mar 2011 11:18:27 +0100	[thread overview]
Message-ID: <20110307101827.GA1762@pcnci.linuxbox.cz> (raw)

e48672fa25e879f7ae21785c7efd187738139593 removed kvm_request_guest_time_update(vcpu);
this breaks 32bit SMP guests using virtio-clock.
thus add unconditional call to kvm_make_request(KVM_REQ_CLOCK_UPDATE, vcpu) to fix the
problem.
