[Buildroot] [pull request] Pull request for branch for-2012.02/lttng

[Thomas Petazzoni]

Hello,

Here is a set of patches that integrate the new generation LTTng
tracing infrastructure into Buildroot. There are several components in
this infrastructure:

 * lttng-modules are kernel modules that implement the kernel side of
   lttng. So far they are compatible with 2.6.38, 2.6.39, 3.0 and 3.1,
   and they don't require any kernel patches, they are simple external
   kernel modules.

 * lttng-tools are the userspace tools to start/stop and configure
   tracing sessions. They are typically installed on the target.

 * liburcu is an implementation of the RCU algorithm in userspace,
   used by lttng-tools.

 * lttng-babeltrace is the utility that allows to convert the binary
   traces generated by lttng-tools into a human-readable text
   format. A host variant of lttng-babeltrace is automatically built
   as a dependency of lttng-tools, because running babeltrace on the
   host machine is probably the most common use case. But building
   lttng-babeltrace for the target is also possible.

 * lttng-libust is an userspace library that allows applications to
   create their own trace events, which are combined with all other
   kernel events by lttng.

Some updates to the popt and util-linux packages are also required in
order to have an host variant of those packages, required to build the
host variant of lttng-babeltrace.

See http://lttng.org/lttng2.0 for more details.

Regards,

Thomas
