    Pull VFIO updates from Alex Williamson:

     - Relax IGD support code to match display class device rather than
       specifically requiring a VGA device (Tomita Moeko)

     - Accelerate DMA mapping of device MMIO by iterating at PMD and PUD
       levels to take advantage of huge pfnmap support added in v6.12
       (Alex Williamson)

     - Extend virtio vfio-pci variant driver to include migration support
       for block devices where enabled by the PF (Yishai Hadas)

     - Virtualize INTx PIN register for devices where the platform does not
       route legacy PCI interrupts for the device and the interrupt is
       reported as IRQ_NOTCONNECTED (Alex Williamson)
