x64, x2apic/intr-remap: Queued invalidation infrastructure (part of VT-d)
Queued invalidation (part of Intel Virtualization Technology for
Directed I/O architecture) infrastructure.
This will be used for invalidating the interrupt entry cache in the
case of Interrupt-remapping and IOTLB invalidation in the case
of DMA-remapping.
