Everyone using lttng-modules from 2.6.1 to 2.6.5 and using moderately
recent Linux kernels should consider upgrading to stable-2.7, or at
least picking up this commit from the stable-2.6 branch:

    Fix: missing Tracepoint prototype checking due to bogus merge

Without this fix, lttng-modules 2.6.x happily builds against more
recent Linux kernels that have incompatible tracepoint prototypes.
The end result is a lttng-modules that builds fine against a kernel,
but which OOPS the kernel when kernel tracing is used.
