This reverts commit 002d8b395fa1c0679fc3c3e68873de6c1cc300a2 which is commit ed914d48b6a1040d1039d371b56273d422c0081e upstream.
Commit b2b29d6d011944 (mm: account PMD tables like PTE tables) is introduced between v5.9 and v5.10, so this fix (commit 002d8b395fa1) should NOT apply to any pre-5.10 branch.
