[PATCH 0/2] iommu/vt-d: Fix posted vCPU vs. posted MSI bugs

[Sean Christopherson]

Fix bugs where using posted MSIs will clobber IRTEs that are configured to
post IRQs to a vCPU, and where undoing vCPU posting fails to put the IRTE
backing into posted MSI mode.

Sean Christopherson (2):
  iommu/vt-d: Put IRTE back into posted MSI mode if vCPU posting is
    disabled
  iommu/vt-d: Don't clobber posted vCPU IRTE when host IRQ affinity
    changes
