	Hello, world!\n

	I've tested RAID-5 on my new dual athlon box, and got the
following messages during system boot:

raid5: measuring checksumming speed
   8regs     :  2550.400 MB/sec
   32regs    :  1702.000 MB/sec
   pIII_sse  :  4735.600 MB/sec
   pII_mmx   :  3910.800 MB/sec
   p5_mmx    :  5016.800 MB/sec
raid5: using function: pIII_sse (4735.600 MB/sec)

	Why does the kernel decide to use the pIII_sse function,
even though the p5_mmx is faster?

	The kernel is 2.4.20-pre5-ac1.
