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. :-(
