Pull vfio updates from Alex Williamson:

- The vfio fsl-mc bus driver has become orphaned. We'll consider
removing it in future releases if a new maintainer isn't found (Alex
Williamson)

- Improved usage of opaque data in vfio-pci INTx handling, avoiding
lookups of the eventfd through the interrupt and irqfd runtime paths
(Alex Williamson)

- Resolve an error path memory leak introduced in vfio-pci interrupt
code (Ye Bin)

- Addition of interrupt support for vfio devices exposed on the CDX
bus, including a new MSI allocation helper and export of existing
helpers for MSI alloc and free (Nipun Gupta)

- A new vfio-pci variant driver supporting migration of Intel QAT VF
devices for the GEN4 PFs (Xin Zeng & Yahui Cao)

- Resolve a possibly circular locking dependency in vfio-pci by
avoiding copy_to_user() from a PCI bus walk callback (Alex
Williamson)

- Trivial docs update to remove a duplicate semicolon (Foryun Ma)

vfio/cdx: add interrupt support

Support the following ioctls for CDX devices:
- VFIO_DEVICE_GET_IRQ_INFO
- VFIO_DEVICE_SET_IRQS

This allows user to set an eventfd for cdx device interrupts and
trigger this interrupt eventfd from userspace.
All CDX device interrupts are MSIs. The MSIs are allocated from the
CDX-MSI domain.

vfio/cdx: add support for CDX bus

vfio-cdx driver enables IOCTLs for user space to query
MMIO regions for CDX devices and mmap them. This change
also adds support for reset of CDX devices. With VFIO
enabled on CDX devices, user-space applications can also
exercise DMA securely via IOMMU on these devices.

ioctls for CDX devices:
- VFIO_DEVICE_GET_INFO:
- VFIO_DEVICE_GET_REGION_INFO
- VFIO_DEVICE_RESET
