Thread-topic: [PATCH][VTD] force boot to fail if interrupt remapping cannot be enabled when iommu=force
Force Xen boot to fail if interrupt remapping fails to enable and the following 
are true: iommu=force is set as xen boot parameter, VT-d engine HW is interrupt 
remapping capable, DMAR_INTR_REMAP bit is set in DMAR flags.  This forces 
iommu=force boot instances has interrupt remapping enabled if HW and BIOS 
supports it.
