    this causes a build warning:
    In file included from arch/blackfin/kernel/signal.c:8:
    include/linux/signal.h:246: warning: 'struct timespec' declared inside
    parameter list
    include/linux/signal.h:246: warning: its scope is only this definition
    or declaration, which is probably not what you want
