* The "output_buff_size" field of the RCP task structure is set to this
* address. It is placed in its own .c, and thus its own .o, since the
* linker aligns individual relocatables to data cache line size (16 byte)
* boundaries.
*
* This avoids the problem where the output buffer length data is accidentally
* scribbled over during a writeback for data sharing the same line.
