Linus Torvalds 826eec5b5e VFIO fixes for v7.2-rc2
- 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)

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.
