Pull VFIO updates from Alex Williamson:
 "Just a few cleanups this cycle:

   - Remove several unused structure and function declarations, and
     unused variables (Dr. David Alan Gilbert, Yue Haibing, Zhang Zekun)

   - Constify unmodified structure in mdev (Hongbo Li)

   - Convert to unsigned type to catch overflow with less fanfare than
     passing a negative value to kcalloc() (Dan Carpenter)"
