This patch intended to integrate the lttng-modules 2.0 package
containing the kernel tracer modules.
LTTng-modules 2.0 is currently in pre-release (-pre11), so we
have to update it when official released.
lttng-2.0 supports lttng-modules extra builds, which don't need
any patches on Linux kernel vs the previous version of lttng.
As described in README of lttng-modules-2.0, so far, it has been
tested in the latest kernel on x86 32/64-bit, and powerpc 32-bit,
, build tested on ARM. So does yocto kernel, the related tests
on qemux86 and qemuppc has been validated and a build test on
qemuarm passed too with this patcheset.
