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"
