Pull IOMMU fixes from Joerg Roedel:
 "Two patches are in here which fix AMD IOMMU specific issues.  One
  patch fixes a long-standing warning on resume because the
  amd_iommu_resume function enabled interrupts.  The other patch fixes a
  deadlock in an error-path of the page-fault request handling code of
  the IOMMU driver.
