The difference is WRT how we handle hash # fault on these address. THP address enables MPSS in segments. We want # to manage devmap hugepage entries similar to THP pt entries. Hence use # H_PAGE_THP_HUGE for devmap huge PTE entries. # # With current code while handling hash PTE fault, we do set is_thp = # true when finding devmap PTE huge PTE entries. # # Current code also does the below sequence we setting up huge devmap # entries. # # entry = pmd_mkhuge(pfn_t_pmd(pfn, prot)); # if (pfn_t_devmap(pfn)) # entry = pmd_mkdevmap(entry); # # In that case we would find both H_PAGE_THP_HUGE and PAGE_DEVMAP set # for huge devmap PTE entries. This results in false positive error like # below. # # kernel BUG at /home/kvaneesh/src/linux/mm/memory.c:4321! # Oops: Exception in kernel mode, sig: 5 [#1] # LE PAGE_SIZE=64K MMU=Hash SMP
