Linux 2.6.32.43+drm33.19
 
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@lists.ubuntu.com.

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

Note that the patch above requires the following reverted patch to be applied
(or the revert reverted):

commit 87682e466f75198056810381c87d2a3a4338dc5c
Author: Steve Conklin <sconklin@canonical.com>
Date: Thu May 26 17:30:21 2011 -0500

Revert "xen: set max_pfn_mapped to the last pfn mapped"

This reverts commit 5490ee42c5725aa3e32634c19f70913e0e634d0c

Not sure, do we already have a bug report for tracking this (like things to keep
in mind when reverted stuff needs to be re-activated)?

Unfortunately for this one we were not yet creating tracking bugs, so
there is no tracking bug for it.

But for more recent reverts, Steve is creating tracking bugs with tag
'stable-next' on it.
