Oh, sorry for the confusion. I think the current feedback I got is
that my restructuring patchset was blocked due to the fact that it is
a partial one. So, if this patchset got checked in, then the psp-sev.h
will have two types of APIs: ones that use sev_data_* structure and
ones that do not. So one of the worries is that this would make the
situation even worse.

So that's why I am thinking that maybe it is fine to just avoid using
sev_data_* for all PSP functions exposed to KVM? I use the number of
arguments as the justification. But that might not be a good one.

In anycase, I will not rush into any code change before we reach a consensus.

Thanks.
