Pull unified attestation reporting from Dan Williams:
 "In an ideal world there would be a cross-vendor standard attestation
  report format for confidential guests along with a common device
  definition to act as the transport.

  In the real world the situation ended up with multiple platform
  vendors inventing their own attestation report formats with the
  SEV-SNP implementation being a first mover to define a custom
  sev-guest character device and corresponding ioctl(). Later, this
  configfs-tsm proposal intercepted an attempt to add a tdx-guest
  character device and a corresponding new ioctl(). It also anticipated
  ARM and RISC-V showing up with more chardevs and more ioctls().

  The proposal takes for granted that Linux tolerates the vendor report
  format differentiation until a standard arrives. From talking with
  folks involved, it sounds like that standardization work is unlikely
  to resolve anytime soo...
