    Subject[patch 06/15] m68k: Make gcc aware that BUG() does not return
    From: Geert Uytterhoeven <geert@linux-m68k.org>

    Use `__builtin_trap()' instead of `asm volatile("illegal")' in the m68k BUG()
    macros (as suggested by Andrew Pinski), to kill warnings in code that assumes
    BUG() does not return.

    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.
