Subject: [PATCH 0/3] clean up interface between KVM and psp

This patch set is trying to help make the interface between KVM and psp
cleaner and simpler. In particular, the patches do the following
improvements:
 - avoid the requirement of psp data structures for some psp APIs.
 - hide error handling within psp API, eg., using sev_decommission.
 - hide the serialization requirement between DF_FLUSH and DEACTIVATE.

Mingwei Zhang (3):
  KVM: SVM: move sev_decommission to psp driver
  KVM: SVM: move sev_bind_asid to psp
  KVM: SVM: move sev_unbind_asid and DF_FLUSH logic into psp
