History
Linus Torvalds bc1bb2a49b - Add the necessary glue so that the kernel can run as a confidential 
SEV-SNP vTOM guest on Hyper-V. A vTOM guest basically splits the
   address space in two parts: encrypted and unencrypted. The use case
   being running unmodified guests on the Hyper-V confidential computing
   hypervisor
 
 - Double-buffer messages between the guest and the hardware PSP device
   so that no partial buffers are copied back'n'forth and thus potential
   message integrity and leak attacks are possible
 
 - Name the return value the sev-guest driver returns when the hw PSP
   device hasn't been called, explicitly
 
 - Cleanups
