From 7c0411d2fabc2e2702c9871ffb603e251158b317 Mon Sep 17 00:00:00 2001 From: Christian König Date: Thu, 28 May 2015 15:51:59 +0200 Subject: drm/radeon: partially revert "fix VM_CONTEXT*_PAGE_TABLE_END_ADDR handling" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We have that bug for years and some users report side effects when fixing it on older hardware. So revert it for VM_CONTEXT0_PAGE_TABLE_END_ADDR, but keep it for VM 1-15.
