Most of those look like small files. I don't see the point of having it
all in separate files - you can just as well put them in tdx.c and carve
out only then when the file becomes too unwieldy to handle.

Didn't you just read what I wrote about "kernel"?

It would be a lot harder to move them to a different location later,
when they're upstream already. I'm talking from past experience here.

But let's see what the others think first.
