Other than R10 being variable here and fixed for __tdx_hypercall(), this looks *EXACTLY* the same as __tdx_hypercall(), or at least a strict subset of what __tdx_hypercall() can do.
Did I miss something?
Another way of saying this: It seems like you could do this with a new version of _tdx_hypercall() (and all in C) instead of a new __tdx_hypercall().
