metag: copy_thread(): rename 'arg' argument to 'kthread_arg'
The 'arg' argument to copy_thread() is only ever used when forking a new kernel thread. Hence, rename it to 'kthread_arg' for clarity. Signed-off-by: Alex Dowad <alexinbeijing@gmail.com> Signed-off-by: James Hogan <james.hogan@imgtec.com>
