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.
