-Subject: [PATCH] iommu/vt-d: Fix kernel panic on boot

-The LTS release 5.10.37 would panic immediately on boot with the

-Commit 416fa531c816 (iommu/vt-d: Preset Access/Dirty bits for IOVA over
-FL, 2021-01-15) seemed to have introduced this problem by changing the
-conditional:
-
-if (!sg) { ...
- sg_res = nr_pages;
- pteval = ((phys_addr_t)phys_pfn << VTD_PAGE_SHIFT) | attr;
-}
-
-to an unconditional:
-
-pteval = ((phys_addr_t)phys_pfn << VTD_PAGE_SHIFT) | attr;
-
-Whilst we do not know exactly what went wrong, this patch was proposed
-in [1] and then reworked into fixing the original commit in [2].
-
-See also [3] for our initial report.
