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.

KVM: VMX: Introduce pi_is_pir_empty() helper
