This is a note to let you know that I have just added a patch titled ttm: Clear the ttm page allocated from high memory zone to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From b47a1b49394d479364b92592fb4f7e77155ee64d Mon Sep 17 00:00:00 2001 From: Zhao Yakui <yakui.zhao@intel.com> Date: Tue, 13 Nov 2012 18:31:55 +0000 Subject: [PATCH] ttm: Clear the ttm page allocated from high memory zone correctly commit ac207ed2471150e06af0afc76e4becc701fa2733 upstream. The TTM page can be allocated from high memory. In such case it is wrong to use the page_address(page) as the virtual address for the high memory page. bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=50241 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Herton Ronaldo Krzesinski <herton.krzesinski@canonical.com> --- drivers/gpu/drm/ttm/ttm_page_alloc.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) -- 1.7.9.5
