Pull iommu fixes from Will Deacon:
 "Joerg's away at the moment so I've been looking after the IOMMU tree
  in his absence. In the process of doing that, I've hoovered up a
  handful of fixes for the AMD and Intel drivers which address a
  combination of the usual out-of-bounds/locking/leak bugs as well as
  some logical issues around SVA and command completion.

  AMD:

   - Fix lockdep splat from nested domain allocation

   - Fix nested domain leak

   - Fix broken synchronisation of command completion

   - Fix OOB write in "ivrs_acpihid" command-line parsing

  VT-d:

   - Prevent SVA for IOMMUs with non-coherent page-table walker

   - Fix OOB write in PMU driver"
