Merge git://git.infradead.org/intel-iommu

Pull Intel IOMMU fix from David Woodhouse:
 "This fixes an oops when attempting to enable 1:1 passthrough mode for
  devices on which VT-d translation was disabled anyway.

  It's actually a long-standing bug but recent changes (commit
  18436afdc11a: "iommu/vt-d: Allow RMRR on graphics devices too") have
  made it much easier to trigger with 'iommu=pt intel_iommu=igfx_off' on
  the command line"

  iommu/vt-d: Fix passthrough mode with translation-disabled devices
