Subject: [PATCH v2 0/3] KVM: VMX: Posted Interrupts fixes

Hey,

This mini-series addresses two bugs plus a small cleanup: 

 1) Considering PID.PIR as opposed to just PID.ON for pending interrupt checks
    in the direct yield code path;
 
 2) Not changing NDST in vmx_vcpu_pi_load(), which addresses a regression. 
    Prior to this, we would observe Win2K12 guests hanging momentarily.
 
 3) Small cleanup to streamline PIR checks with a common helper.

The cleanup is done last to simplify backports.

	Joao

v2:
* Fixed missing Tb/Rb tags;
* Fixed broken Sob chains (on first two patches)
* Only test PID.PIR if PID.SN=1 (third patch)

Joao Martins (3):
  KVM: VMX: Consider PID.PIR to determine if vCPU has pending interrupts
  KVM: VMX: Do not change PID.NDST when loading a blocked vCPU
  KVM: VMX: Introduce pi_is_pir_empty() helper
