#     Pull VFIO updates from Alex Williamson:
#     
#      - Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
#        which allows both larger device image sizes for migration, beyond the
#        previous 4GB limit, and also read-ahead support for improved
#        migration performance (Yishai Hadas)
#     
#      - A new bus master control interface for the CDX bus driver where there
#        is no in-band mechanism to toggle device DMA as there is through
#        config space on PCI devices (Nipun Gupta)
#     
#      - Add explicit alignment directives to vfio data structures to reduce
#        the chance of breaking 32-bit userspace. In most cases this is
#        transparent and the remaining cases where data structures are padded
#        work within the existing rules for extending data structures within
#        vfio (Stefan Hajnoczi)
#     
#      - Resolve a bug in the cdx bus driver noted when compiled with clang
#        where missing parenthesis result in the wrong operation (Nathan
#        Chancellor)
#     
#      - Resolve errors reported by smatch for a function when dealing with
#        invalid inputs (Alex Williamson)
#     
#      - Add migration support to the mtty vfio/mdev sample driver for testing
#        and integration purposes, allowing CI of migration without specific
#        hardware requirements. Also resolve many of the short- comings of
#        this driver relative to implementation of the vfio interrupt ioctl
#        along the way (Alex Williamson)
#
