This makes it sound like the dummy page table for the private alias is
also called a shared page table, but in the drawing below it looks like
only the shared alias is called "shared PT".

I think the point of putting these in a union is that they only apply
to shadow paging and so can't be used with TDX. I think you are putting
more than the sizeof(void *) in there as there are multiple in the same
category. But there seems to be a new one added, *shadowed_translation.
Should it go in there too? Is the union because there wasn't room
before, or just to be tidy?
I think the commit log should have more discussion of this union and
maybe a comment in the struct to explain the purpose of the
organization. Can you explain the reasoning now for the sake of
discussion?

This particular memcache zeros the allocations so it is safe to free
this without regard to whether sp->private_spt has been set and that
the allocation caller is not in place yet. It would be nice to add this
detail in the log.
