From f32af63ed1327451cb91e3816fa043b6c2c52db1 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 22 Sep 2009 18:12:26 +0000 Subject: powerpc/mm: Fix 40x and 8xx vs. _PAGE_SPECIAL The test to check whether we have _PAGE_SPECIAL defined is broken, since we always define it, just not always to a meaninful value :-) That broke 8xx and 40x under some circumstances. This fixes it by adding _PAGE_SPECIAL for both of these since they had a free PTE bit, and removing the condition around advertising it.
