This reverts commit 920a42d8b854b1f112aef97a21f0549918889442 which is
commit 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.
