From 3ff38e1874863827374b02b4f31c73faa3744e1c Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Mon, 15 Oct 2018 06:37:41 +0000 Subject: powerpc/book3s64: fix dump_linuxpagetables "present" flag Since commit bd0dbb73e013 ("powerpc/mm/books3s: Add new pte bit to mark pte temporarily invalid."), _PAGE_PRESENT doesn't mean exactly that a page is present. A page is also considered preset when _PAGE_INVALID is set. This patch changes the meaning of "present" and adds a status "valid" associated to the _PAGE_PRESENT flag. Fixes: bd0dbb73e013 ("powerpc/mm/books3s: Add new pte bit to mark pte temporarily invalid.")
