    Pull VFIO updates from Alex Williamson:
    
     - Remove redundant resource check in vfio-platform (Angus Chen)
    
     - Use GFP_KERNEL_ACCOUNT for persistent userspace allocations, allowing
       removal of arbitrary kernel limits in favor of cgroup control (Yishai
       Hadas)
    
     - mdev tidy-ups, including removing the module-only build restriction
       for sample drivers, Kconfig changes to select mdev support,
       documentation movement to keep sample driver usage instructions with
       sample drivers rather than with API docs, remove references to
       out-of-tree drivers in docs (Christoph Hellwig)
    
     - Fix collateral breakages from mdev Kconfig changes (Arnd Bergmann)
    
     - Make mlx5 migration support match device support, improve source and
       target flows to improve pre-copy support and reduce downtime (Yishai
       Hadas)
    
     - Convert additional mdev sysfs case to use sysfs_emit() (Bo Liu)
    
     - Resolve copy-paste error in mdev mbochs sample driver Kconfig (Ye
       Xingchen)
    
     - Avoid propagating missing reset error in vfio-platform if reset
       requirement is relaxed by module option (Tomasz Duszynski)
    
     - Range size fixes in mlx5 variant driver for missed last byte and
       stricter range calculation (Yishai Hadas)
    
     - Fixes to suspended vaddr support and locked_vm accounting, excluding
       mdev configurations from the former due to potential to indefinitely
       block kernel threads, fix underflow and restore locked_vm on new mm
       (Steve Sistare)
    
     - Update outdated vfio documentation due to new IOMMUFD interfaces in
       recent kernels (Yi Liu)
    
     - Resolve deadlock between group_lock and kvm_lock, finally (Matthew
       Rosato)
    
     - Fix NULL pointer in group initialization error path with IOMMUFD (Yan
       Zhao)
