From c1a7ca0de38c23a15f652b1693afd56c9f07b16c Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 8 Oct 2012 12:15:13 -0400 Subject: [PATCH] drm/radeon/cayman: set VM max pfn at MC init MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit No need to emit them at VM flush as we no longer use variable sized page tables now that we support 2 level page tables. This matches the behavior of SI (which does not support variable sized page tables).
