It's just a little hack to create an exception panic. You can
accomplish the same thing with the call that Scott mentioned
earlier:
char *a = (char *)0x0;
*a = 0;
So just replace the __asm__ call with the stuff above. I'm surprised
you weren't able to compile -- I've been copying that code in for a
long time, and haven't had any problem whatsoever.
