[2.6.32+drm33-longterm] Linux 2.6.32.50+drm33.21

I am announcing the release of the 2.6.32.50+drm33.21 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 at lists.ubuntu.com.
This release contains patches from upstream 2.6.32.50, 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
or
git://kernel.ubuntu.com/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
or
http://kernel.ubuntu.com/git?p=smb/linux-2.6.32.y-drm33.z.git;a=summary

+ help
+ On revisions of the PL310 prior to r3p2, the Store Buffer does
+ not automatically drain. This can cause normal, non-cacheable
+ writes to be retained when the memory system is idle, leading
+ to suboptimal I/O performance for drivers using coherent DMA.
+ This option adds a write barrier to the cpu_idle loop so that,
+ on systems with an outer cache, the store buffer is drained
+ explicitly.
