[2.6.32+drm33-longterm] Linux 2.6.32.43+drm33.19
From: Stefan Bader
Date: Thu Jul 14 2011 - 04:13:06 EST
I am announcing the release of the 2.6.32.43+drm33.19 longterm tree.
This tree is based on 2.6.32 and generally has all of the stable updates
applied. Except those to the DRM subsystem, which was based on 2.6.33 and
took updates from that upstream stable as long as that existed. It will
continue to add patches to the DRM subsystem as long as they are valid
according to the stable update rules (Documentation/stable_kernel_rules.txt).
DRM patches for this tree should be sent to kernel-team@xxxxxxxxxxxxxxxxx
This release contains patches from upstream 2.6.32.43, but dropped any patches
to the DRM subsystem.
The updated 2.6.32.y-drm33.z tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git
and can be browsed through git web via:
http://git.kernel.org/?p=linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git;a=summary
