[RFC PATCH 5/9] sched: export-GPL task_prio

[Mathieu Desnoyers <mathieu.desnoyers@efficios.com>]

Exporting the task_prio() symbol to GPL modules is useful for kernel
tracers implemented as kernel modules. It exports information which is
already available through /proc in a way which allows it to be sampled
by kernel tracers with low overhead.
