This is a note to let you know that I have just added a patch titled drm/radeon: do not try to uselessly update virtual memory pagetable to the linux-3.8.y-queue branch of the 3.8.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-3.8.y-queue This patch is scheduled to be released in version 3.8.13.4. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 015a02ea12ac2be3e53431b763a531c54b277c71 Mon Sep 17 00:00:00 2001 From: Jerome Glisse <jglisse@redhat.com> Date: Thu, 6 Jun 2013 12:41:17 -0400 Subject: drm/radeon: do not try to uselessly update virtual memory pagetable commit 3813f5ca9ab7a00e80a17aab34f155453c66c78a upstream. If a buffer is never bound to a virtual memory pagetable than don't try to unbind it. Only drawback is that we don't update the pagetable when unbinding the ib pool buffer which is fine because it only happens at suspend or module unload/shutdown. Fixes spurious messages about buffers without VM mappings.
