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
