[2.6.32+drm33-longterm] Linux 2.6.32.38+drm33.17

I am announcing the release of the 2.6.32.38+drm33.17 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 updates the DRM subsystem only.

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

-Stefan

Note that last time I looked there were 2 changes we already carried through
security updates and one which we were carrying even longer (not to care about
the lid status).

Integrating LTTng in Ubuntu

Hello,

LTTng, the Linux Trace Toolkit Next Generation, is a project that aims
at producing a highly efficient full system tracing solution. It is
composed of several components to allow tracing of the kernel, of
userspace, trace viewing and analysis and trace streaming.

Ubuntu is more and more popular as a server-grade distribution and
having a comprehensive tracing infrastructure built into the kernel
would allow system administrators to investigate problems as they appear
without patching the kernel and rebooting the server.

For example, with LTTng you know really quickly what is the I/O
bandwidth (network or disk) associated with a particular process, and in
this process which file is the culprit for slowing down your whole
system. LTTng can also be used as a highly efficient userspace tracer
with UST. When the user-space and kernel-space traces are combined,
application developpers and sysadmins have a very detailed overview of
what is happening on their system.

Over the last months, the size of the LTTng kernel patchset has been
considerably shrinked for Linux distributions by removing all
LTTng-specific instrumentation from the tree.

You can find the latest patchset here [1].

Please note that the patches within this patchset are elected as the
first items from the LTTng project to eventually get into the mainline
Linux kernel. This includes TRACE_EVENT() changes, the LTTng trace
clocks and the Generic Ring Buffer Library. Please take into account

[Lucid-ec2] SRU: Sync upstream changes from 2.6.32.35.15

Except one (which only adds the deviations file and has no impact at
all), all of these patches are changes to files which the Xen patchset
has been creating clones. So upstream changes take no effect in the
ec2 kernel otherwise.

There is one more patch which we carry (and has been verified to fix
migration issues) that needs backporting:

* xen: events: do not unmask event channels on resume

I have that patch prepared, but as it likely depends on the other
changes around interrupt handling and delivery, I would put this
one into the big update that is pending.

Tested a kernel based on _all_ patches (big patchset and these) running
the regression tests on a local test system with no issues.

-Stefan

The following changes since commit a2954ed27c57dfcc6cdcc1be012364322294df30:
  Stefan Bader (1):
        UBUNTU: Start new release
