From: He Zhe <zhe.he@windriver.com>

This is based on meta/recipes-kernel/lttng/lttng-modules_2.10.9.bb and is for
those who want to build lttng-modules with bleeding edge kernel, to avoid
regularly backporting patches from upstream.

Note that PREFERRED_VERSION needs to be set to select this recipe instead of the
tar ball one.
