This reverts commit 002d8b395fa1c0679fc3c3e68873de6c1cc300a2.
b2b29d6d011944 (mm: account PMD tables like PTE tables) is
introduced between v5.9 and v5.10, so this fix should NOT
apply to any pre-5.10 branch
Missing sign-off.
Also I think you should make it clear that the patch is for stable in
subject
(like [PATCH for stable]) and Cc stable folks like Greg to catch their
attention.
Thanks.
