Yes, I know. But that is not my question. Lemme try again.

My previous comment was:

"I think you should simply export sev_do_cmd() and call it instead."

In this case, the API is a single function - sev_do_cmd() - which the
hypervisor calls.

So my question still stands: why is it better to have silly wrappers
of sev_do_cmd() instead of having the hypervisor call sev_do_cmd()
directly?
