From 9c97b5ab4a91c18c2e7654f044cbff446cfd979b Mon Sep 17 00:00:00 2001 From: Christian König Date: Thu, 3 Dec 2015 20:54:35 +0100 Subject: drm/amdgpu: partially revert "drm/amdgpu: fix VM_CONTEXT*_PAGE_TABLE_END_ADDR" v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The gtt_end is already inclusive, we don't need to subtract one here. v2 (chk): keep the fix for the VM code, cause here it really applies.
