+From: Huang Pei <huangpei@loongson.cn>
+
+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.
