Subject: [PATCH v2 00/11] SVM: vNMI (with my fixes)

Hi!

This is the vNMI patch series based on Santosh Shukla's vNMI patch series.

In this version of this patch series I addressed most of the review feedback
added some more refactoring and also I think fixed the issue with migration.

I only tested this on a machine which doesn't have vNMI, so this does need
some testing to ensure that nothing is broken.

Best regards,
       Maxim Levitsky

Maxim Levitsky (9):
  KVM: nSVM: don't sync back tlb_ctl on nested VM exit
  KVM: nSVM: clean up the copying of V_INTR bits from vmcb02 to vmcb12
  KVM: nSVM: explicitly raise KVM_REQ_EVENT on nested VM exit if L1
    doesn't intercept interrupts
  KVM: SVM: drop the SVM specific H_FLAGS
  KVM: x86: emulator: stop using raw host flags
  KVM: SVM: add wrappers to enable/disable IRET interception
  KVM: x86: add a delayed hardware NMI injection interface
  KVM: SVM: implement support for vNMI
  KVM: nSVM: implement support for nested VNMI

Santosh Shukla (2):
  x86/cpu: Add CPUID feature bit for VNMI
  KVM: SVM: Add VNMI bit definition
