iommu/vt-d: Fix misuse of iommu_domain_identity_map() (2020-06-23 10:08:32 +0200)

----------------------------------------------------------------
IOMMU Fixes for Linux v5.8-rc2:

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
