Merge tag 'vfio-v6.10-rc1' of https://github.com/awilliam/linux-vfio
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)
