SKD022: VM Entry That Clears TraceEn May Generate a FUP.

        If VM entry clears Intel(R) PT (Intel Processor Trace)
        IA32_RTIT_CTL.TraceEn (MSR 570H, bit 0) while PacketEn is 1 then a
        FUP (Flow Update Packet) will precede the TIP.PGD (Target IP Packet,
        Packet Generation Disable).  VM entry can clear TraceEn if the
        VM-entry MSR-load area includes an entry for the IA32_RTIT_CTL MSR.
