Subject: [PATCH 0/3] x86/sev: Carve out the SVSM support code

From: "Borislav Petkov (AMD)" <bp@...en8.de>

Hi,

I've been meaning to do this for a while now but didn't have a good idea how
to do it nicely. Using the internal header makes it almost trivial.

Thx.

  x86/sev: Move the internal header
  x86/sev: Add internal header guards
  x86/sev: Carve out the SVSM code into a separate compilation unit
