Pull iommu fixes from Joerg Roedel:
 "A couple of Intel VT-d fixes:

   - Make Intel SVM code 64bit only. The code uses pgd_t* and the IOMMU
     only supports long-mode page-table formats, so its broken on 32bit
     anyway.

   - Make sure GFX quirks in for Intel VT-d are not applied to untrusted
     devices. Those devices might gain full memory access otherwise.

   - Identity mapping setup fix.

   - Fix ACS enabling when Intel IOMMU is off and untrusted devices are
     detected.

   - Two smaller fixes for coherency and IO page-table setup"
