While the last patch is technically targetting core-mm and is not directly related to arm64, I'd like to to go via the arm64 tree so that the wider performance improvement series (v2 to be posted shortly) that depends on this series doesn't have to be robust to the fix not being present. I've included maintainers/reviewers for all the arches that are (trivially) touched due to the API changes, hoping for some ACKs. Changes since v1 [1] ==================== - Added Rb from Anshuman - Thanks! - Added "#ifndef __PAGETABLE_PMD_FOLDED" around PUD_SIZE in flush_hugetlb_tlb_range() I've marked all of these as candidates for backport to stable. Applies on top of v6.14-rc3. All mm selftests run and pass.
