The CPU GPs if we try and set a bit in a variable MTRR mask above the limit of physical address bits on the host. We hit this when loading a migration from a host with a larger physical address limit than our destination (e.g. a Xeon->i7 of same generation) but previously used to get away with it until 48e1a45c started checking that msr writes actually worked. It seems in our case the GP probably comes from KVM emulating that GP.
