a3dbba7a60 Yves has sent us a ~600 Kb patch, which shuts up gcc entirely for the 
entire kernel.
Unfortunately we didn't send him a copy of the style guide before he did it.
I'm trying to find all the benign and downright sound bits and will commit
them without any other explanation than "YF fix" if they are merely cosmetic.

This also removes a possible race condition where after a bus reset (the

3f624a0187 Removed misleading copyright note. This file contains just 
definitions taken from the PCI specs. Part of them were typed
in by Wolfgang Stanglmeier, the (at that time unneeded) rest
by Charles Hannum (thanks !).

ea6ecb4e52 Disable disconnect after drive timeouts, since these 
may be the result of reselect following too fast for
the driver to notice. Not the final solution, but the
problem has been seen only with very few devices.

6398cf3113 Reapplied all of Stefan's changes. What a mess - the files were modified 
and moved at the same time. This made it *very* difficult to fix the
revision log lossage that happend when the files were moved. SIGH.
