| |
m68k: implement __clear_user(), which is needed by fs/signalfd.c
Since we always let the MMU do all checking, clear_user() and __clear_user() are identical. The old clear_user() is renamed to __clear_user() for consistency.

In personal conversations with technical people, I call myself a hacker. But when I'm talking to journalists I just say "programmer" or something like that. -- Linus Torvalds - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
