x86: KVM guest: use paravirt function to calculate cpu khz
We're currently facing timing problems in guests that do calibration under heavy load, and then the load vanishes. This means we'll have a much lower lpj than we actually should, and delays end up taking less time than they should, which is a nasty bug. Solution is to pass on the lpj value from host to guest, and have it preset. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
