From 8937ba48dcf62b5cdf7abb93652914af16756f50 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 18 Nov 2013 14:58:12 +0530 Subject: [PATCH] powerpc/mm: Only check for _PAGE_PRESENT in set_pte/pmd functions We want to make sure we don't use these function when updating a pte or pmd entry that have a valid hpte entry, because these functions don't invalidate them. So limit the check to _PAGE_PRESENT bit. Numafault core changes use these functions for updating _PAGE_NUMA bits. That should be ok because when _PAGE_NUMA is set we can be sure that hpte entries are not present.
