The GuestCtl1 CP0 register can contain the GuestID used for root TLB operations, which affects TLB matching. The other TLB registers are already dumped out to the log on a machine check exception due to multiple matching TLB entries, so also dump the value of the GuestCtl1 register if GuestIDs are supported.
