Merge tag 'vfio-v5.15-rc1' of git://github.com/awilliam/linux-vfio
Pull VFIO updates from Alex Williamson:
- Fix dma-valid return WAITED implementation (Anthony Yznaga)
- SPDX license cleanups (Cai Huoqing)
- Split vfio-pci-core from vfio-pci and enhance PCI driver matching to
support future vendor provided vfio-pci variants (Yishai Hadas, Max
Gurtovoy, Jason Gunthorpe)
- Replace duplicated reflck with core support for managing first open,
last close, and device sets (Jason Gunthorpe, Max Gurtovoy, Yishai
Hadas)
- Fix non-modular mdev support and don't nag about request callback
support (Christoph Hellwig)
- Add semaphore to protect instruction intercept handler and replace
open-coded locks in vfio-ap driver (Tony Krowiak)
- Convert vfio-ap to vfio_register_group_dev() API (Jason Gunthorpe)
