Satoshi Asami d7629dff3b A fast memory copy for Pentiums using floating point registers. 
It is called from copyin and copyout.

The new routine is conditioned on I586_CPU and I586_FAST_BCOPY, so you
need

options "I586_FAST_BCOPY"

(quotes essenstial) in your kernel config file.

Also, if you have other kernel types configured in your kernel, an
additional check to make sure it is running on a Pentium is inserted.
(It is not clear why it doesn't help on P6s, it may be just that the
 Orion chipset doesn't prefetch as efficiently as Tritons and friends.)

Bruce can now hack this away. :)
