My proposal for non-generic kernels:
o only code for the configured CPU is compiled
and linked (saves ~100k for R3000 kernels!)
o removed a lot of indirect function calls
o removed Ralf's "cowboy patch"
o added sanity check for DECstations (print warning
if the kernel is configured for the wrong CPU)
