[patch 08/29] frv: Use generic init_task

From: Thomas Gleixner
Date: Mon Apr 30 2012 - 16:22:02 EST


Same code. Use the generic version. The special Makefile treatment is
pointless anyway as init_task.o contains only data which is handled by
the linker script. So no point on being treated like head text.
