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 ?
