Hi Eric,

I am not targeting VT-d 2.5 for SVA related work. I am working on the
rest of the APIs for supporting VT-d v3, which includes guest PASID
bind, fault reporting, and invalidation passdown from the guest. These
are based on some recent patches from Baolu.

So I feel it is better for you to take over bind_pasid_table() API in
your series. I will drop it from my next version.

Thanks,

Jacob
