  DAX/ZONE_DEVICE, and module unload/reload"

* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  KVM: MMU: Do not treat ZONE_DEVICE pages as being reserved
  KVM: VMX: Introduce pi_is_pir_empty() helper
  KVM: VMX: Do not change PID.NDST when loading a blocked vCPU
  KVM: VMX: Consider PID.PIR to determine if vCPU has pending interrupts
  KVM: VMX: Fix comment to specify PID.ON instead of PIR.ON
  KVM: X86: Fix initialization of MSR lists
  KVM: fix placement of refcount initialization
  KVM: Fix NULL-ptr deref after kvm_create_vm fails
