This is a note to let you know that I have just added a patch titled drm/radeon: add semaphore trace point 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. -Luis ------ From 8ae87a279145fe0790a627bf0faab6712039263d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= <christian.koenig@amd.com> Date: Tue, 12 Nov 2013 12:58:04 +0100 Subject: drm/radeon: add semaphore trace point MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit bd80c8ba995c1dbdddee14acc55c541c499e0442 upstream.
