Merge tag 'vfio-v7.2-rc2' of https://github.com/awilliam/linux-vfio

Pull VFIO fixes from Alex Williamson:
 "Mostly straightforward fixes here, inconsistent runtime PM handling
  due to global device policies, bitfield races, unwind path gaps,
  teardown ordering, and a misplaced library flag.

   - Fix racy bitfield updates in vfio-pci-core and the mlx5 vfio-pci
     variant driver with a binary split between setup/release and
     runtime modified flags. These were noted across several Sashiko
     reviews as pre-existing issues (Alex Williamson)

   - Fix runtime PM inconsistency where the vfio-pci driver module_init
     could modify the idle PM policy of existing devices through globals
     managed in vfio-pci-core, leading to unbalanced runtime PM
     operations (Alex Williamson)

   - Restore mutability of writable vfio-pci module options by further
     pulling policy globals out of vfio-pci-core, to instead be latched
     per device at device init. Provide visibility of the per device
     latched values through debugfs (Alex Williamson)

   - Fix missing VGA arbiter uninit callback in unwind path (Alex
     Williamson)

   - Reorder device debugfs removal before device_del() to avoid gap
     where debugfs is available with stale devres pointers (Alex
     Williamson)

   - Move UUID library linking flag from vfio selftest Makefile into
     libvfio.mk to avoid exposing such dependencies when linking with
     KVM selftests (Sean Christopherson)"
