stable inclusion from stable-5.10.37 commit 416fa531c8160151090206a51b829b9218b804d9 bugzilla: 51868 CVE: NA -------------------------------- [ Upstream commit a8ce9ebb ] The Access/Dirty bits in the first level page table entry will be set whenever a page table entry was used for address translation or write permission was successfully translated. This is always true when using the first-level page table for kernel IOVA. Instead of wasting hardware cycles to update the certain bits, it's better to set them up at the beginning.
