Hi -

I've revised and improved the intel spinlock debugging I posted two
weeks ago.

Attached is the diff (against 2.4.8).  It moves the debugging routines
into a seperate C file (this is how sparc does it), fixes the race
condition noted by Tachino Nobuhiro, and adds debugging routines for
read-write spinlocks.

It compiles and runs fine on my single processor machine, and continues
to detect problems with the USB SCSI code.  Anybody want to try it on an
SMP box and make sure it's OK?

Make sure you do a "make dep" after applying the patch, since it exports
symbols...
