Sorry, I did not intend to add these spr numbers.  They got added to
our additions-list when we diff'ed our 2.4-test11 to 2.4.9.  (The only
reference to these numbers that I could find are in the ibm 401).

Yes,  I was sloppy.  I will do better next time.

For others,
to get the most benefit with gdb on the kernel, it needs to be
compiled with -g.  This allows the root user to peek around with
"gdb vmlinux-g /proc/kcore".  I don't know if there is a need for
this or how to make it configurable, but here is a simple patch:
