MIPS: Remove unused task_struct.trap_no field.
It is initialized to zero and only ever read. Remove it, and pass zero in its place. Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1531/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
