Fixed in r219698, sorry.

Actually, I think we should remove i486 from GENERIC at some point.  
It has too many limitations.  For example, I really love to implement 
atomic 64-bit mem read/write using cmpxchg8b (no 0xf00f joke, please) 
but I cannot do that cleanly without removing I486 support or 
checking cpu_class at run-time. :-(
