Having two Fixes: for one patch presumably makes backporting more
complicated and adds risk of making mistakes.

So I have split this into a three-patch series and I've fixed up the patch naming:

Subject: madvise:madvise_cold_or_pageout_pte_range(): don't use mapcount() against large folio for sharing check
Subject: madvise:madvise_free_huge_pmd(): don't use mapcount() against large folio for sharing check
Subject: madvise:madvise_free_pte_range(): don't use mapcount() against large folio for sharing check

I haven't added cc:stable at this time - that awaits the description of
user-visible effects.
