Merge with Linux 2.4.0-test9. Please check DECstation, I had a number

of rejects to fixup while integrating Linus patches.  I also found
that this kernel will only boot SMP on Origin; the UP kernel freeze
soon after bootup with SCSI timeout messages.  I commit this anyway
since I found that the last CVS versions had the same problem.
