Yes, it works,
HVM_INFO is only removed for IPF side.

In IA32 side, it uses HVM_INFO to pass parameter to hvmloader.

But in IPF side, it uses HOB interface to pass parameter to guest Firmware
in a predifined address, such as vcpu number.
SMP vti has nothing to do with HVM_INFO.
We are working at SMP VTI, the root cause is that vcpu parameter is removed for
Merge, we'll add it at somewhere, we'll send out patch ASAP.
