#     kernel/sys.c: fix prototype of prctl_get_tid_address()
#     
#     tid_addr is not a "pointer to (pointer to int in userspace)"; it is in
#     fact a "pointer to (pointer to int in userspace) in userspace".  So
#     sparse rightfully complains about passing a kernel pointer to
#     put_user().
