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.
