Subject: [PATCH 0/2] KVM: SEV: Fall back to __vmalloc() for SEV-ES scratch

Two cleanups related to handling failure to setup the GHCB scratch area
for SEV-ES.  Found by inspection when reviewing the SNP series.  Compile
tested only.

Sean Christopherson (2):
  KVM: SEV: Return appropriate error codes if SEV-ES scratch setup fails
  KVM: SEV: Fall back to __vmalloc() for SEV-ES scratch area if
    necessary
