[v2,0/3] KVM: qemu patches for few KVM features I developed

Message

These patches implement the qemu side logic to support
the KVM features I developed recently.

All 3 patches are for features that are accepted upstream in KVM.

V2: rebased and fixed patch 2 to compile without kvm

Best regards,
    Maxim Levitsky

Maxim Levitsky (3):
  KVM: use KVM_{GET|SET}_SREGS2 when supported.
  gdbstub: implement NOIRQ support for single step on KVM
  KVM: SVM: add migration support for nested TSC scaling
