Subject: [PATCH 0/2] KVM: SVM: Fix error handling bugs in SEV migration

Fixes for bugs reported by Dan Carpenter, found by static analysis.  All
credit goes to Dan, the bug report all but wrote the code for me.

Compile tested only, I don't have a SEV migration sussed out yet.

Sean Christopherson (2):
  KVM: SVM: Return -EFAULT if copy_to_user() for SEV mig packet header
    fails
  KVM: SVM: Fix sev_pin_memory() error checks in SEV migration utilities
