Date: Tue, 20 Oct 2015 08:48:08 +0800 From: lizf@...nel.org To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Christian König <christian.koenig@....com>, Alex Deucher <alexander.deucher@....com>, Zefan Li <lizefan@...wei.com> Subject: [PATCH 3.4 58/65] drm/radeon: partially revert "fix VM_CONTEXT*_PAGE_TABLE_END_ADDR handling" From: Christian König <christian.koenig@....com> 3.4.110-rc1 review patch. If anyone has any objections, please let me know. ------------------ commit 7c0411d2fabc2e2702c9871ffb603e251158b317 upstream. 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.
