Subject: wait_task_* cleanups: use copy_wait_opts_to_user() in do_wait()
From: Vitaly Mayatskikh <v.mayatskih@gmail.com>
All copy-paste getrusage() and put_user() code in wait_task_* functions is
replaced by call to copy_wait_opts_to_user()
Use copy_wait_opts_to_user() in do_wait() to clean up user's siginfo
structure.
