commit 181e505952c5e4b4beb287d0022ea3cd20f23e74
Merge: 86579aa 4ed6a54

    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"
    
    * git://git.infradead.org/intel-iommu:
      iommu/vt-d: Fix passthrough mode with translation-disabled devices
