From c9a803fb17bcec0e7527dc8fa055e56a9691abbb Mon Sep 17 00:00:00 2001 From: LEROY Christophe Date: Fri, 19 Sep 2014 10:36:09 +0200 Subject: [PATCH] powerpc/8xx: _PMD_PRESENT already set in level 1 entries When a PMD entry is valid, _PMD_PRESENT is set. Therefore, forcing that bit during TLB loading is useless.
