Subject: [ 15/34] frv: Use core allocator for task_struct

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@...utronix.de>

commit c6ae063aaf3786b9db7f19a90bf4ed8aaebb7f90 upstream.

There is no point having a copy of the core allocator.
