I was expecting that BUG will get removed in the next patch. But I don't
see it in the next patch. Considering

@@ -475,11 +453,10 @@ static void free_hugepd_range(struct mmu_gather *tlb, hugepd_t *hpdp, int pdshif
        for (i = 0; i < num_hugepd; i++, hpdp++)
                hpdp->pd = 0;

-#ifdef CONFIG_PPC_FSL_BOOK3E
-	hugepd_free(tlb, hugepte);
-#else
-	pgtable_free_tlb(tlb, hugepte, pdshift - shift);
-#endif
+	if (shift >= pdshift)
+		hugepd_free(tlb, hugepte);
+	else
+		pgtable_free_tlb(tlb, hugepte, pdshift - shift);
 }

What is that I am missing ?
