I noticed a small bug in previous patch. Use this one instead.
(change update_db_intercept(to_svm(svm)) -> update_db_intercept(&svm->vcpu))
If NMI is received during handling of another NMI it should be injected
immediately after IRET from previous NMI handler, but SVM intercept IRET
before instr

If NMI is received during handling of another NMI it should be injected
immediately after IRET from previous NMI handler, but SVM intercept IRET
before instruction execution so we can't inject pending NMI at this
point and there is not way to request exit when NMI window opens. This
patch fix SVM c
