Subject: [RFC PATCH v2 04/69] KVM: TDX: Add TDX "architectural" error codes
Date:   Fri,  2 Jul 2021 15:04:10 -0700

Add TDX completion status codes for SEAMCALL and TDG_VP_VMCALL.

TDX-SEAM uses bits 31:0 to return more information, so these error codes
for SEAMCALL will only exactly match RAX[63:32]. [1] Section 17.1 Interface
Function Completion Status Codes
Completion status codes for TDG.VP.VMCALL is defined in
[2] Chapter 3 TDG.VP.VMCALL Interface.
