  vfio/pci: Handle INTx IRQ_NOTCONNECTED (2025-03-17 15:15:17 -0600)

----------------------------------------------------------------
VFIO updates for v6.15-rc1

 - 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)

----------------------------------------------------------------
